Create Simple Contact Form in CodeIgniter with Database Save Option

On 11/26/2017

Hi, sometime back I wrote a tutorial on codeigniter contact form with email sending option. It received good response and I got requests from blog readers to write about saving the codeigniter contact form data into database. For doing so, it requires a proper database to store the form data and some tweaking to the script. Though it's easy for experienced developers, it's proves to be a challenge for newbie's to do it by themselves. So I decided to write a detailed tutorial here about creating simple contact form in codeigniter and saving the data into database.

Contact Form Workflow

The workflow of the codeigniter contact form we build goes like this. Create a simple contact form for the user to enter 'name', 'email-id', 'subject' and 'message'. Upon proper server side validation we should insert the form data into database. If the database insert operation succeeds, we notify the user with some success message else the error message.

Creating CodeIgniter Contact Form and Save in Database

As the foremost step we need to create database with proper fields to store the contact form data. I'm going to use MySQL DB and create a database with name 'mysite'. Next we should create a table inside the database. For that run this below 'sql' file to create the table required to store the contact form data.


-- Database: `mysite`
-- Table structure for table `contacts`
  `name` varchar(60) NOT NULL,
  `email` varchar(255) NOT NULL,
  `subject` varchar(120) NOT NULL,
  `message` text NOT NULL,
  PRIMARY KEY (`id`)

Connect to Database

Next we have to connect the codeigniter app to our 'mysite' database. Copy paste the below connectivity settings to 'application\config\database.php' file and you are done.

$db['default']['hostname'] = 'localhost'; //server
$db['default']['username'] = 'username'; //mysql username
$db['default']['password'] = 'password'; //mysql password
$db['default']['database'] = 'mysite'; //database name
$db['default']['dbdriver'] = 'mysql';

Note: Change the above db settings according to your needs.

Next we'll move on to the coding phase. We need to create a controller and a view file for this contact form. For styling the form, I will use twitter bootstrap css in view file (Not mandatory. Feel free to use your own stylesheets). You can learn here to set up the twitter bootstrap css with codeigniter.

The Contact Form Controller File ('contactform.php')

Create a controller file with name 'contactform.php' inside 'application\controllers' folder. Now copy paste the below code to it and save.

class contactform extends CI_Controller
    public function __construct()
        $this->load->library(array('session', 'form_validation'));

    function index()
        //set validation rules
        $this->form_validation->set_rules('name', 'Name', 'trim|required|xss_clean|callback_alpha_space_only');
        $this->form_validation->set_rules('email', 'Emaid ID', 'trim|required|valid_email');
        $this->form_validation->set_rules('subject', 'Subject', 'trim|required|xss_clean');
        $this->form_validation->set_rules('message', 'Message', 'trim|required|xss_clean');
        //run validation on post data
        if ($this->form_validation->run() == FALSE)
        {   //validation fails
            //insert the contact form data into database
            $data = array(
                'name' => $this->input->post('name'),
                'email' => $this->input->post('email'),
                'subject' => $this->input->post('subject'),
                'message' => $this->input->post('message')

            if ($this->db->insert('contacts', $data))
                // success
                $this->session->set_flashdata('msg','<div class="alert alert-success text-center">We received your message! Will get back to you shortly!!!</div>');
                // error
                $this->session->set_flashdata('msg','<div class="alert alert-danger text-center">Oops! Some Error.  Please try again later!!!</div>');
    //custom callback to accept only alphabets and space input
    function alpha_space_only($str)
        if (!preg_match("/^[a-zA-Z ]+$/",$str))
            $this->form_validation->set_message('alpha_space_only', 'The %s field must contain only alphabets and space');
            return FALSE;
            return TRUE;

As you can see in the above controller file, first we have loaded the required files in the constructor function. And the index() is the default function to be called when the controller is invoked. Here is where we run the validation check on the posted data and if it is valid, we save the contact form data into mysql table 'contacts' using the $this->db->insert('contacts', $data); statement.

The statement $this->session->set_flashdata() is used to notify success or failure message to the user, and the flashdata message will be displayed when the page is redirected.

We also have a custom callback alpha_space_only() which is used for validating the name field to allow only alphabets and space characters.

The Contact Form View File ('contact_form_view.php')

Next we have to create the view file which we load in the controller. Create a file with name 'contact_form_view.php' inside 'application\views' folder. Now copy paste the below code to it and save.

<!DOCTYPE html>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>CodeIgniter Contact Form Example</title>
    <link href="<?php echo base_url("assets/bootstrap/css/bootstrap.css"); ?>" rel="stylesheet" type="text/css" />
<div class="col-md-6 col-md-offset-3">
    <div class="panel panel-default">
        <div class="panel-heading">
            <h3 class="panel-title">Contact Form</h3>
        <div class="panel-body">
            <?php $attributes = array("name" => "contactform");
            echo form_open("contactform/index", $attributes);?>
            <div class="form-group">
                <label for="name">Name</label>
                <input class="form-control" name="name" placeholder="Your Full Name" type="text" value="<?php echo set_value('name'); ?>" />
                <span class="text-danger"><?php echo form_error('name'); ?></span>
            <div class="form-group">
                <label for="email">Email ID</label>
                <input class="form-control" name="email" placeholder="Email-ID" type="text" value="<?php echo set_value('email'); ?>" />
                <span class="text-danger"><?php echo form_error('email'); ?></span>

            <div class="form-group">
                <label for="subject">Subject</label>
                <input class="form-control" name="subject" placeholder="Subject" type="text" value="<?php echo set_value('subject'); ?>" />
                <span class="text-danger"><?php echo form_error('subject'); ?></span>

            <div class="form-group">
                <label for="message">Message</label>
                <textarea class="form-control" name="message" rows="4" placeholder="Message"><?php echo set_value('message'); ?></textarea>
                <span class="text-danger"><?php echo form_error('message'); ?></span>

            <div class="form-group">
                <button name="submit" type="submit" class="btn btn-success">Submit</button>
            <?php echo form_close(); ?>
            <?php echo $this->session->flashdata('msg'); ?>

As I have already mentioned about using bootstrap css, we have linked the bootstrap css file in the view to style the user interface. All the css classes used inside the html markup belong to bootstrap framework.

Now run the controller in the browser (http://localhost/cidemo/index.php/contactform) and you can see a neatly aligned contact form like this.

CodeIgniter Contact Form Example

In case of any validation errors, we repopulate the form data with codeigniter's set_value() method and use the form_error() method to display the error message below the respective form fields like this,

Validation Errors Displayed in Contact Form

As for notifications, the statement $this->session->flashdata('msg'); is included below the form to display the success or failure message in green or red color respectively.

Success Message Notification
Failure Message Notification

And that explains about creating codeigniter contact form and storing the form data into mysql database. I hope this codeigniter contact form tutorial is helpful to you. Feel free to voice your comments if you have any queries.

  1. Hi why it has an error it says

    Fatal error: Call to undefined function form_open() in C:\xampp\htdocs\Website\contact_form_view.php on line 104

    the line 104 was

    echo form_open("contactform/index", $attributes);?>

    1. It seems like form helper is not loaded. You can try loading it at the autoload.php file inside config folder like this,

      $autoload['helper'] = array('form', 'url');

      If this doesn't help, replace the system folder of codeigniter app with a fresh copy. This will fix the corrupted files.


  2. Unable to load the requested file: contact_form_view.php

  3. Unable to load the requested file: contact_form_view.php

  4. Unable to load the requested file: contact_form_view.php

  5. Nice tutorial but I keep getting this error
    Unable to access an error message corresponding to your field name Name.(xss_clean)

    1. Hi! xss_clean is no longer required. Please remove it from the validation rules and keep them like this,

      $this->form_validation->set_rules('subject', 'Subject', 'trim|required');
      $this->form_validation->set_rules('message', 'Message', 'trim|required');

      This'll fix the issue. Cheers.

    2. xss_clean is no longer part of form validation. The alternative is not to use it, as xss_clean is doing sanitization and not validation.

      xss_clean now is part of security helper. If you need to do it, after validation you do a:


      or simply:

      // on each data. NO need to load the class Security
      - $this->security->xss_clean($data) ;
