Paytm Payment Gateway Integration in PHP - Example

On 1/22/2018 Be the first to comment!

Hi! In this tutorial, we will see how to integrate paytm payment gateway in php. Mobile wallets have become immensely popular in recent years and paytm is highly trusted among online customers. Many people use it every day for doing online recharges, DTH & other bill payments. It reduces the risk of exposing customer's banking credentials and credit card details to hackers. Therefore, Paytm is a good solution for online payments on your Website and Mobile Apps.

Integrating the paytm gateway in your application is quite easy and below I'll show how to do it with php.

Paytm Payment Gateway PHP Integration:

If your application is based on php, then you don't have to go from scratch. You can quickly integrate paytm into the application using the paytm kit for php. It covers all the basics, you just have to download and use it in the following way.

Step-1) Download Paytm Kit

Download Paytm Payment Kit for PHP and extract its contents. Then move the 'PaytmKit' folder to your working directory.

Step-2) Register for Paytm Sandbox Account

Next, you must register for merchant sandbox account with paytm and collect the necessary details to use with the API. Visit this link and provide your mobile number, email id and password and register an account. You will be provided with merchant id, key etc. Store them in a text file to use it later.

Step-3) Configure the Settings

Now you must configure the payment gateway settings with the data you received in Step-2. Open 'PaytmKit' > 'lib' > 'config_paytm.php' file and update the following details.

define('PAYTM_ENVIRONMENT', 'TEST'); //change this to 'PROD' to use it in production environment
define('PAYTM_MERCHANT_KEY', 'YOUR_MERCHANT_KEY'); //Change this to the merchant key downloaded from the portal
define('PAYTM_MERCHANT_MID', 'YOUR_MERCHANT_ID'); //change this to merchant id received from paytm
define('PAYTM_MERCHANT_WEBSITE', 'WEBSITE_NAME'); //change this to website name received from paytm

Step-4) Create Payment Form

Finally create a payment form to make transactions. Here we need to pass the form action to file 'pgRedirect.php' located inside the 'PaytmKit' folder. This will take care of verifying the checksum and other details and process the payment via the paytm wallet.

                    <input type="text" class="form-control" id="INDUSTRY_TYPE_ID" name="INDUSTRY_TYPE_ID" maxlength="12" size="12"  autocomplete="off" tabindex="3" value="Retail">
                <div class="form-group">
                    <input type="text" class="form-control" id="CHANNEL_ID" name="CHANNEL_ID" maxlength="12" size="12" autocomplete="off" tabindex="4" value="WEB">
                <div class="form-group">
                    <input type="text" class="form-control" id="TXN_AMOUNT" name="TXN_AMOUNT" autocomplete="off" tabindex="5" value="1">
                <div class="form-group">
                    <input type="submit" name="submit" value="CheckOut" class="btn btn-success btn-lg">

This is just a usual php form, but remember to pass all the required parameters as I did. And for designing UI, I have used bootstrap css here, but you can happily skip it if you don't want.

And even though php codeigniter framework loosely follows Model-View-Controller pattern it doesn’t force it on you. While controller classes are required for application development, the models and view files are purely optional.

The Model-View-Controller pattern isolates the application logic from the user interface and the database communication.

Twitter Bootstrap CSS is used in this tutorial series for designing the user interface for codeigniter application and there are some dedicated articles covering the usage of bootstrap framework with codeigniter application. But you are encouraged to write down your own style sheets if you prefer.

Using Twitter Bootstrap with CodeIgniter saves the hassle of writing CSS stylesheets of your own and lets you focus on development. Later you can customize bootstrap styles to suit your need. That is the best part of using MVC pattern as the presentation layer (i.e., view) is separate, you can change the look and feel of the app anytime without disturbing the rest of it.

What Makes a Wireless Adapter Compatible with Kali?

Kali is a popular Linux Distro commonly used by security and penetrating testing professionals. Not all wireless adapters are made to work with Kali Linux. Only the drivers and chipsets decides if they are compatibile with the OS or not.

In addition, if you run it as a VM, the USB adapter must also be compatible with the host operating system.

Any of the above recommended devices will be good for pentesting, but you are called to decide which one is right for your configuration.

Long-range adapters with big dBi antenna are great for distance but not exactly compact. On the other hand smaller ones with built-in antenna are good for staying low profile.

Over To You:

So these are the best wireless adapters and usb dongles for kali linux. Though all these adapters works well with Kali, just make sure if it is the right one for your environment. For example if you wish to run Kali on Virtual box in Windows 7 host then make sure the card is compatible with Windows 7 OS. Also you must be cautious about the coverage range. Antenna with bigger dBi would be better for longer range. This helps you avoid future trouble. If you find this useful please share it with others to give them good suggestion.

Hi, we’ll see how to remove index.php from url in codeigniter. Even though codeigniter uses search engine friendly urls, nobody would have missed the awkward presence of 'index.php' in between those codeigniter's urls. Have you ever wondered how to get rid of it to get more clean urls in your codeigniter application? Say your app has an url something like and you want it to look like Yes, you can do it. In codeigniter removing index.php from url should be done by rewriting urls in htaccess file.

Recommended Read: CodeIgniter/MySQL Tutorial - Read and Display data with Twitter Bootstrap

Step 1: Enable Mod Rewrite Option in your APACHE Server

To rewrite urls in the htaccess file, the mod_rewrite option should be enabled in the apache server. Goto apache's "httpd.conf" file and search for the line,

LoadModule rewrite_module modules/

If the above line is preceded with # (in which case, the module is disabled), then remove the # (hash) symbol to enable url rewriting.

Step 2: Create '.htaccess' File

Next create the .htaccess file at the root directory. To create the htaccess file, open your favourite text editor and create a new text file. Save it as ".htaccess" (make sure you type the filename within quotes to avoid the file to be saved as text file) in the root directory.

htaccess file codeigniter

Now copy paste this code to the htaccess file and save it.

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteCond %{THE_REQUEST} ^GET.*index\.php [NC]
    RewriteCond %{REQUEST_URI} !/system/.* [NC]
    RewriteRule (.*?)index\.php/*(.*) /$1$2 [R=301,NE,L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ /index.php/$1 [L]

If you run your codeigniter app as a subdirectory instead of root domain like, instead of then the above code won't work. You have to tweak it little to tell that your site runs as a subdirectory. Add this code to the htaccess file instead of the above one.

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteCond %{THE_REQUEST} ^GET.*index\.php [NC]
    RewriteCond %{REQUEST_URI} !/system/.* [NC]
    RewriteRule (.*?)index\.php/*(.*) /$1$2 [R=301,NE,L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php/$1 [L]

Step 3: Modify CodeIgniter Config Settings

Open config.php file under application >> config folder and search for the line,

$config['index_page'] = 'index.php';

Remove index.php from it to look like this,

$config['index_page'] = '';

Now restart apache and check the url. eg., instead of

If it doesn't work, you may be having problem with uri protocol. In that case find $config['uri_protocol'] ='AUTO' setting in config file and replace with $config['uri_protocol'] = 'REQUEST_URI'.

Restart apache server again and you can check the codeigniter site to see that index.php has been removed from codeigniter url.

How to Choose the Best Wireless Network Adapter - Buying Guide

Tech savvy or not, knowing few things about Wi-fi and Adapters will help you choose the right adapter that works best in your network system. So let's see some of the important features you must consider before buying a USB Wireless Adapter.

1. What are Wireless Protocols?

802.11 is the number representing the Wireless protocols. It is the universal standard set for wireless products so that they can communicate with each other without trouble.

The current Wi-Fi standard is 802.11ac and introduced in 2013. It works only on 5 GHZ band but can transfer data much faster than wireless N.

But most devices in today's market use the previous 802.11n (or) Wireless-N protocol. This is the widely used wifi standard and works on both 2.4 GHz and 5 GHz band.

Dual Band: Adapters that works on both 2.4GHz and 5GHz frequency ranges are known as dual-band wireless adapters.

To simply put the newer 802.11ac wireless adapters have better speed over Wireless N device. So can you buy the 802.11ac dongle?

Well! It depends.

The fact is 802.11ac is fast but has less coverage. Remember it only works on 5 GHz range? The higher frequency does not travel as far as the lower 2.4 GHz frequency.

So if there is not much distance between adapter and router then the best option would be an 802.11ac dongle. Else go for the dual band Wireless-N dongle which is good for long distance range.

2. Wireless Frequencies

There is two type of frequencies used for wireless transmission. One is 2.4 GHz and the other one is 5 GHz range. Up until 2013, only 2.4 GHz band was used. But later due to overcrowding of wireless networks they have introduced the higher 5 GHz band.

The higher the frequency the less the signal can travel through barriers. So a 2.4GHz dongle will transmit data farther than the new 5GHz dongles.

Numerous networks still use 2.4GHz band and collide with other wireless devices fighting to get a signal through. And the fact that it travels a greater distance and penetrates through walls makes the situation even worse.

Hence the introduction of the 5GHz band. It travels less distance and has mighty speed. The network is also less crowded so there is a little chance for the collision with other N/w s.

3. Distance

Antennas play a larger role when it comes to distance. Some USB wireless adapters come with the built-in antenna which is good for staying low profile. But these internal antennas will not transmit signal as far as large external antennas.

On the other hand adapters with external antennas cover long distance well and carry wireless signal better than the built-in one. They come with a screw-in antenna which can be easily replaced with large dBi antenna as per distance requirement.

Generally, antenna size is measured in dBi. As a general rule of thumb, the larger the dBi the higher the coverage. But keep in mind having an adapter with large dBi antenna will not guarantee better signal at long distance - as external factors like barriers, adapter wattage will affect the signal quality.

4. Speed

Speed matters in a wireless connection... A LOT!

Till date, the Wireless-AC adapters (802.11ac) have the fastest data transfer speed of up to 1.3Gbps. The second best is the Wireless-N adapters (802.11n) with a speed of up to 300 Mbps which indeed is not at all slow for personal use.

But 802.11ac will only work in 5GHz range so if you prefer distance over speed then stick to the old 802.11n which works on 2.4GHz band.

Just keep in mind.

2.4 GHz band travel far but has less speed (relative).

5 GHz band travel less but with greater speed.

Certain dual band adapters are capable of using both 2.4GHz and 5GHz bands for maximum speed and said to have 1200Mbps transfer rate. Note that it's just a theoretical estimation and hard to be achieved in real-life. Wireless speed is always relative to the environment you live in.

5. Easy to Use

Wireless adapters are easy to setup and use it. With PCI adapters you have to go through installation process via setup CD and all. But that's not the case with USB Wifi adapters. Most of the USB Adapters are the plug-and-play type. All you have to do is to connect them to a free USB Port of your computer and the system will automatically detect the device and run set up for the first time. Once the driver is installed you are good to go from there.

6. Compatibility

The wireless adapter must be compatible with the router to send and receive data. Dual band routers will work with any adapter. But an old router will only work on 2.4 GHz range. So make sure the adapter also works in the similar range.

In case you are not sure about the router being used, just get a Dual Band Wireless N adapter. It will work with any router.

Besides your Desktop/Laptop Operating system is also important. A Wi-Fi adapter must be compatible with the computer OS in order to work. So make sure your adapter works on a particular OS and also have updated drivers required for it.

So if you buy a wireless adapter to work on Windows 10 machine, it must be compliant with Windows 10 OS. The fact it works on Windows 7 or 8 doesn't mean it will also work on Win 10 version.

7. USB 2.0 Vs USB 3.0

USB 3.0 is mandatory for 802.11ac adapters. This is because their peak data rate exceeds the USB 2.0 speed on 2.4GHz band.

USB 2.0 can transfer data at 480Mbps, the new USB 3.0 at 5Gbps speed. This is only theoretical, but real world's performance is always lower than this.

PCI Based or USB Wi-Fi Adapter? Which One to Choose?

Before starting your hunt for wireless adapters, you must first know that there are two types of wireless adapters commonly used these days. Let's see what they are.

USB Wireless Adapter

The first type of wireless adapter is USB based. USB Wifi adapters are the simplest to install and use among the two types. It's because of their plug and play nature. They work like a flash drive in this context.

You have to simply plug it into a USB Port, and then the computer will automatically detect, run setup and install the necessary drivers. After that, you can connect it to any available Wi-Fi network and you are good to go from there. The installation process takes place only for the first time you use it on a PC or Laptop.

Well! The wifi adapter is external and requires one free USB Port. In some cases, the devices are bigger and might as well block nearby ports. Plus you may need it to be out of the way of other computer cables.

In fact, it's good to use an USB extension cable to connect USB Wireless adapters. They will be out of your way and can be kept farther from PC to pick up wifi signals better.

PCI Based Wireless Adapter

PCI stands for Peripheral Component Interconnect and wireless adapters of these types should be plugged into the PCI slot of the computer's motherboard. These devices are bigger than the USB network adapters and come with powerful antennas sticking out at the back of the adapters.

PCI wifi adapters generally crowd over the area they are attached to. Plus somewhat harder to setup and use for an average user. Nonetheless, they are excellent in terms of wireless transmission and long distance coverage.

But overall I would happily choose anytime a USB wireless adapter over PCI ones just because of their simplicity and ease of use.

Advantages of Using USB Wireless Adapters

A USB wireless adapter is the easiest solution to put a device online. It's cheap, effective and has several advantages over using wired connection.

  • Free of Cords - The first and foremost benefit of using the wireless adapter is it eliminates the necessity of computer cables. Your computer desk will no more be a clutter of cords. You get to have true mobility if you work with laptop or tablet. When you have wifi, you don't have sit at your work table. You are free to take your work to couch or bed. Plus USB wireless adapters stay low profile and most of them look no bigger than a flash drive.
  • No Hardware Installation - There are several ways to set up wifi on your computer. Of all the choices USB wireless adapters is the popular choice for most users. It's because they are simple external devices. You have to simply plug them into a USB port, install drivers and connect to wifi network. That's all to the total set up. And the plug-and-play feature is even better.
  • But PCI based adapters have complicated setup. In some cases, you have to open up the computer or laptop case and fix wifi card to motherboard slot. Not a favorable choice at all.
  • Easy Replacement - Does your desktop doesn't have a built-in wifi card? Or you laptop wifi is broken? Then don't worry. You don't have to upgrade your entire computer which is quite costly. Get a USB wireless adapter compatible with your system OS. That'll do. It is the simplest solution to enable wifi on a computer. USB wifi adapters are very cheap and you can replace it at any time if the need arises.
  • Multi-Device Support - One of the key benefit of usb wireless adapter is it can be shared among multiple devices. Since it's an external device mounting and un-mounting is quite easy. So you can use the very same usb adapter on your laptop, desktop, tablet etc. The device is small so you can carry it anywhere you go and use it at your convenience.

FAQ on USB Wireless Adapters

I'm not sure about the Network used? Which Wi-Fi Adapter is right for me?

It's easier to get confused with all those wireless protocol numbers, operational frequency etc. If your network operates on 2.4GHz frequency then there's no point in buying a wireless adapter that only works on 5GHz band.

So in case you are not sure about the wireless network being used, then get a dual-band usb wifi dongle. They will work on most of the networks since they operate on both 2.4GHz and 5GHz band.

How can I know if an USB Wireless Adapter works on my Computer?

A wireless adapter needs to have driver software for the Operating system being used. So if you have Windows 10 PC, the wireless adapter you get to work with the machine must be Windows 10 compliant.

I live in City? Which Adapter should I buy?

802.11ac protocol only works in the new 5GHz band and doesn't travel far. So the network will be confined to a small area.

On the other hand, the older Wireless N works on 2.4GHz band and is widely used by many and travel far than 5GHz range. So there is a greater possibility for network collision in a crowded city which pulls down the wifi speed.

If you live in a city with crowded neighborhood your best choice would be a 5GHz Wifi adapter. If you live outside of the city limit with few neighbors then go for 2.4 GHz adapter which gives you greater coverage.

Can I use USB Wireless Adapter as Wi-Fi Hotspot?

Using USB wireless adapters as Wi-Fi Hotspot let you share the PC's internet connection with multiple devices like smartphone, tablet etc.

If your computer runs Windows 10 here's a way to do it.

Open Windows Settings > Network & Internet and choose 'Mobile HotSpot' and complete the setup wizard. You might as well need to tweak security settings to grant permission for this.

Over to You

USB Wireless Adapters are inexpensive and convenient solution to connect desktop computers to wifi networks. But then the market is crowded with so many brands claiming their adapters are the best among all. And it's also a tough task to narrow down to an adapter that works best for your desktop pc. Just remember, the Wi-Fi USB adapter must be compatible with your network and has drivers for the OS you use. The new 5GHz adapter will have high-speed but has short range. If you are not sure about the network and all, get a dual-band adapter. It will work with any network old or new.

PHP CodeIgniter Pagination with Twitter Bootstrap Styles - Example

On 1/20/2018 24 Comments so far

PHP Codeigniter framework provides a good number of libraries required for building a website with codeigniter and pagination library is one among them. For those who are not familiar with the term pagination, this refers to the set of numbered links that allows you to navigate from page to page to view a large set of data. For example let's say you want to fetch and display some data from database and it contains several hundreds of records. In that case pagination will be very useful to display the database resultset in chunks and let the user to skim through several page links (similar to google search results).

However the pagination links in codeigniter are plain looking in nature and a little customization to codeigniter pagination doesn't hurt. Here we'll see in this tutorial, how to style codeigniter pagination links with twitter bootstrap styles.

Implement Twitter Bootstrap Styles in CodeIgniter Pagination

We'll see an example below to fetch and display the list of department names and their department head in a neat table view along with pagination links at the bottom.

MySQL Database Example

As an example I'll use this below 'employee' database for this tutorial.

-- Database: `employee`
  `int_id` int(4) NOT NULL AUTO_INCREMENT,
  `var_dept_name` varchar(50) NOT NULL,
  `int_hod` int(5) NOT NULL,
  KEY `int_id` (`int_id`)

  `int_id` int(5) NOT NULL AUTO_INCREMENT,
  `var_emp_name` varchar(50) NOT NULL,
  `int_dept_id` int(4) NOT NULL,
  PRIMARY KEY (`int_id`)

The Model ('models/department_model.php')

First we create a model file with a method to fetch and return the entire department details along with the head of the department employee name.

class department_model extends CI_Model{
    function __construct()
        // Call the Model constructor

    //fetch department details from database
    function get_department_list($limit, $start)
        $sql = 'select var_dept_name, var_emp_name from tbl_dept, tbl_emp where tbl_dept.int_hod = tbl_emp.int_id order by var_dept_name limit ' . $start . ', ' . $limit;
        $query = $this->db->query($sql);
        return $query->result();

The Controller ('controllers/department.php')

Next create the controller file and load the codeigniter pagination library and the department model file which we created earlier in the constructor method. Then create the index() function where we configure the behavior of the pagination library with the $config[] array and create the pagination links to be displayed at the bottom of the department table in the view file.

class department extends CI_Controller
    public function __construct()

        //load the department_model

    public function index()
        //pagination settings
        $config['base_url'] = site_url('department/index');
        $config['total_rows'] = $this->db->count_all('tbl_dept');
        $config['per_page'] = "5";
        $config["uri_segment"] = 3;
        $choice = $config["total_rows"] / $config["per_page"];
        $config["num_links"] = floor($choice);

        //config for bootstrap pagination class integration
        $config['full_tag_open'] = '<ul class="pagination">';
        $config['full_tag_close'] = '</ul>';
        $config['first_link'] = false;
        $config['last_link'] = false;
        $config['first_tag_open'] = '<li>';
        $config['first_tag_close'] = '</li>';
        $config['prev_link'] = '&laquo';
        $config['prev_tag_open'] = '<li class="prev">';
        $config['prev_tag_close'] = '</li>';
        $config['next_link'] = '&raquo';
        $config['next_tag_open'] = '<li>';
        $config['next_tag_close'] = '</li>';
        $config['last_tag_open'] = '<li>';
        $config['last_tag_close'] = '</li>';
        $config['cur_tag_open'] = '<li class="active"><a href="#">';
        $config['cur_tag_close'] = '</a></li>';
        $config['num_tag_open'] = '<li>';
        $config['num_tag_close'] = '</li>';

        $data['page'] = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;

        //call the model function to get the department data
        $data['deptlist'] = $this->department_model->get_department_list($config["per_page"], $data['page']);           

        $data['pagination'] = $this->pagination->create_links();

        //load the department_view

As you can see in the above code, we have integrated bootstrap's '.pagination' class to codeigniter pagination links. Using the '.active' css class will highlight the active page in the links.

The View ('views/department_view.php')

Finally create view file to display the department list in a neat striped table with bootstrap pagination links at the bottom.

    <div class="row">
        <div class="col-md-12">
            <table class="table table-striped table-hover">
                        <th>Department Name</th>
                        <th>Head of Department</th>
                    <?php for ($i = 0; $i < count($deptlist); ++$i) { ?>
                        <td><?php echo ($page+$i+1); ?></td>
                        <td><?php echo $deptlist[$i]->var_dept_name; ?></td>
                        <td><?php echo $deptlist[$i]->var_emp_name; ?></td>
                    <?php } ?>
    <div class="row">
        <div class="col-md-12 text-center">
            <?php echo $pagination; ?>

We have used bootstrap table styles such as '.table', '.table-striped', '.table-hover' to display the department list in a neat format and at the bottom with pagination links.

Open the controller in the browser and you get the department details displayed like this.


I hope now you get a better understanding of integrating twitter bootstrap styles with codeigniter pagination links.

How to Merge Two JSON Strings into One with PHP

On 1/19/2018 Be the first to comment!

Hi! In this tutorial we will see how to merge two json strings into one in php. People often mistakes JSON for object or array but it's the string representation of a JavaScript object. In a recent project, I wanted to combine two jsons. That is, I have to make two API calls and combine their results into one. It is a rest api and returns the response as json. The task is simpler than I thought. It employs a similar technique I used here earlier when dealing with json. Let me show you how to do it.

php merge two json strings

PHP - Merging Two JSON into One:

If you are new to working with JSON, don't worry. PHP offers native functions to handle it easily. The idea is to decode the json data, write it to an array and encode it back to json.

Below are the steps involved in the process.

STEP-1) Let's take two different jsons containing couple of employee details.

$json1 = '{"id": "GD01", "name": "Garrett Davidson", "position": "System Administrator", "location": "New York"}';
$json2 = '{"id": "DW02", "name": "Donna Winters", "position": "Senior Programmer", "location": "Seattle"}';

STEP-2) Next we should convert the json strings into an array and join them into a single array.

$array[] = json_decode($json1, true);
$array[] = json_decode($json2, true);

Keep in mind the function json_decode() will return stdObject by default. To make it return associative array, we have to set the second parameter as 'true'.

STEP-3) Then convert the merged array to json. For this we have to use the function json_encode(). While encoding, I have included the token 'JSON_PRETTY_PRINT' to add proper indentation so that it's easy on the eyes.

$result = json_encode($array, JSON_PRETTY_PRINT);

STEP-4) Finally print the merged json. You can simply echo it, but the output will look messy and difficult to read. So be sure to set the headers with right content type to display indents and blank spaces between the texts.

header('Content-type: text/javascript');
echo $result;

This will produce the below output,

// output
        "id": "GD01",
        "name": "Garrett Davidson",
        "position": "System Administrator",
        "location": "New York"
        "id": "DW02",
        "name": "Donna Winters",
        "position": "Senior Programmer",
        "location": "Seattle"

As you can see, the output consists of a nested json combining the data from $json1 and $json2.

Here is the complete php script for json merging process.


$json1 = '{"id": "GD01", "name": "Garrett Davidson", "position": "System Administrator", "location": "New York"}';
$json2 = '{"id": "DW02", "name": "Donna Winters", "position": "Senior Programmer", "location": "Seattle"}';

// decode json to array
$array[] = json_decode($json1, true);
$array[] = json_decode($json2, true);

// encode array to json
$result = json_encode($array, JSON_PRETTY_PRINT);

// print merged json
header('Content-type: text/javascript');
echo $result;

You can also store the json output in a file instead of displaying it in the browser window.
