Ajax add, edit, delete records in database using bootstrap modal with php and jquery

Today we are going to see How to Ajax add, edit, delete records in the database using bootstrap modal with PHP and jquery. In this tutorial, I will explain about how to add and edit with single bootstrap form. For using this Script you can easily add and edit the user's information. Here I have used some jquery script for display dynamic record to the form. Let's see deep in the tutorial.

Database

Create a new table as users_information with below structure. insert some dumping data. This data will load our bootstrap model.
CREATE TABLE `users_information` (
  `id` int(11) NOT NULL,
  `name` varchar(50) NOT NULL,
  `email` varchar(100) NOT NULL,
  `country` varchar(50) NOT NULL,
  `mobile` varchar(50) NOT NULL,
  `about` varchar(300) NOT NULL,
  `dob` date NOT NULL,
  `last_update` datetime NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

--
-- Dumping data for table `users_information`
--

INSERT INTO `users_information` (`id`, `name`, `email`, `country`, `mobile`, `about`, `dob`, `last_update`) VALUES
(1, 'Karthick', 'mostlikers@gmail.com', 'India', '9876543210', 'Blogger', '1992-12-02', '2017-04-17 00:00:00'),
(2, 'Arunkumar', 'arun@mostlikers.com', 'India', '8976543210', 'Author', '1991-05-21', '2017-04-17 00:00:00');

Database Connection

create a new file as config.php then paste the copied below code inside the file.
<?php 
    $db = new mysqli('localhost','root','','mostlikers');
    // Check connection
    if (mysqli_connect_errno()) {
      echo "Failed to connect to MySQL: " . mysqli_connect_error(); exit;
    }
?>


Load Table Data

Create new file as index.php then follow the below steps
  • Write a query to fetch the table users information
  • Load the query information to Bootstrap table.
  • Convert users information to Jquery data value.
  • Load the ajax() and jquery functions.

Fetch the user's information

Fetch the query for all inserted records in the user's information table with name Ascending order.
<?php 
    include('config.php');
    session_start();
    $result = $db->query('SELECT * FROM users_information order by name ASC');
    $data_record = $result->num_rows;
?>


Load bootstrap CDN Files. 

Load Bootstrap CDN file to your <HEAD> tag
<head> 
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
    <link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
    <script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>

Load the query information to Bootstrap table.

var page_0 - load the users with JSON format this data will load bootstrap model. Here I have used the same form for add and edit. So, I have called same class .model_form in add /edit icon it will load the bootstrap model.

<div class="row">
      <div class="col-md-4"></div>
      <div class="col-md-4"> <h3>Add/Edit Users information</h3></div>

           <?php endif; ?>               
            </tbody>
        </table>
          <?php
              if(isset($_SESSION['flash_msg'])) :  
               $message = $_SESSION['flash_msg'];

<!-- /form modal -->



Ajax Script

Load the ajax script for add, update and delete the user information
<script src="js/script.js"></script>
<script type="text/javascript">
$(document).ready(function() {
    $(document).on('click','.model_form',function(){
        $('#form_modal').modal({
          keyboard: false,
          show:true,
          backdrop:'static'
        });
        var data = eval($(this).attr('data'));
        $('#id').val(data.id);
        $('#name').val(data.name);
        $('#country').val(data.country);
        $('#email').val(data.email);
        $('#about').val(data.about);
        $('#mobile').val(data.mobile);
        $('#dob').val(data.dob);
        if(data.id!="")
            $('#pop_title').html('Edit');
        else
            $('#pop_title').html('Add');
       
    });  
    $(document).on('click','.delete_check',function(){
      if(confirm("Are you sure to delete data")){
        var current_element = $(this);
        url = "add_edit.php";
        $.ajax({
        type:"POST",
        url: url,
        data: {ct_id:$(current_element).attr('data')},
        success: function(data) { //location.reload(); 
          $('.'+$(current_element).attr('data')+'_del').animate({ backgroundColor: "#003" }, "slow").animate({ opacity: "hide" }, "slow");
        } 
      });
      }
     });     
});
</script>









Add and delete the user's information PHP code

Create a new file called as add_edit.php After the ajax() call users information form data post to this page. 
<?php 
    session_start();
    include("config.php");
    if(isset($_POST['form_data'])) :
        $user_name = $db->real_escape_string($_POST['name']);
        $user_email = $db->real_escape_string($_POST['email']);
        $user_country = $db->real_escape_string($_POST['country']);
        $user_about = $db->real_escape_string($_POST['about']);
        $date = new DateTime($db->real_escape_string($_POST['dob']));
        $user_dob = $date->format('Y-m-d');
        $user_mobile = $db->real_escape_string($_POST['mobile']);
        $id = ($_POST['id']!="") ? $db->real_escape_string($_POST['id']) : '';
        if($id!="") :
            $query = " UPDATE `users_information` SET `name`= '$user_name', `email`='$user_email',
             `country`='$user_country', `mobile`='$user_mobile' , `about`='$user_about',
             `dob`='$user_dob' WHERE id=$id";
            $msg = "Successfully Updated Your Record";
        else: 
            $query = " INSERT INTO `users_information` SET `name`= '$user_name', `email`='$user_email',
             `country`='$user_country', `mobile`='$user_mobile' , `about`='$user_about',`dob`='$user_dob'";
            $msg = "Successfully Inserted Your Record";         
        endif;
        $sql = $db->query($query);
        $_SESSION['flash_msg'] = $msg;
        header("Location:index.php");
    endif;

    if(isset($_POST['ct_id'])) :
        $id = ($_POST['ct_id']!="") ? $db->real_escape_string($_POST['ct_id']) : '';
        if($id!="") :
            $query = "DELETE FROM users_information WHERE id =$id";
            $sql = $db->query($query);
            echo 1;
        else :
            echo 0;
        endif;
    else :
        echo 0;
    endif;
?>
