PHP - Ajax Delete Table Row In MySQLi

In this tutorial we will create a Ajax Delete Table Row In MySQLi using PHP. This code will delete a table row in MySQLi database when user click the delete button.The code use jQuery ajax to dynamically delete a table row from MySQLi server without refreshing web page and modify HTML table to display message that tells the data is being deleted. This is a user-friendly kind of program feel free user it in your program.

We will be using jQuery a JavaScript framework that design to simplify HTML DOM tree traversal and manipulation. It can retrieve DOM and manipulate each properties of an element based on different criteria such as id, class, etc.

Getting Started:

First you have to download & install XAMPP or any local server that run PHP scripts. Here's the link for XAMPP server

And this is the link for the jquery that i used in this tutorial

Lastly, this is the link for the bootstrap that i used for the layout design

Creating Database

Open your database web server then create a database name in it db_ajax_delete, after that click Import then locate the database file inside the folder of the application then click ok.

Creating the database connection

Open your any kind of text editor(notepad++, etc..). Then just copy/paste the code below then name it conn.php.

  1. <?php
  2. $conn = mysqli_connect('localhost', 'root', '', 'db_ajax_delete') or die(mysqli_error());
  3. if(!$conn){
  4. die("Error: Failed to connect to database");
  5. }
  6. ?>

Creating The Interface

This is where we will create a simple form for our application. To create the forms simply copy and write it into your text editor, then save it as index.php.

  1. <!DOCTYPE html>
  2. <html lang="en">
  3. <head>
  4. <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1"/>
  5. <link rel="stylesheet" type="text/css" href="css/bootstrap.css"/>
  6. </head>
  7. <body>
  8. <nav class="navbar navbar-default">
  9. <div class="container-fluid">
  10. <a class="navbar-brand" href="">Sourcecodester</a>
  11. </div>
  12. </nav>
  13. <div class="col-md-3"></div>
  14. <div class="col-md-6 well">
  15. <h3 class="text-primary">PHP - Ajax Delete Table Row In MySQLi</h3>
  16. <hr style="border-top:1px dotted #ccc;"/>
  17. <div class="col-md-4">
  18. <form method="POST" action="save.php">
  19. <div class="form-group">
  20. <label>Firstname</label>
  21. <input type="text" name="firstname" class="form-control"/>
  22. </div>
  23. <div class="form-group">
  24. <label>Lastname</label>
  25. <input type="text" name="lastname" class="form-control" />
  26. </div>
  27. <div class="form-group">
  28. <label>Address</label>
  29. <input type="text" name="address" class="form-control"/>
  30. </div>
  31. <center><button name="save" class="btn btn-primary">Save</button></center>
  32. </form>
  33. </div>
  34. <div class="col-md-8">
  35. <table class="table table-bordered">
  36. <thead class="alert-info">
  37. <tr>
  38. <th>Firstname</th>
  39. <th>Lastname</th>
  40. <th>Address</th>
  41. <th>Action</th>
  42. </tr>
  43. </thead>
  44. <tbody style="background-color:#fff;">
  45. <?php
  46. require 'conn.php';
  47. $query = mysqli_query($conn, "SELECT * FROM `member` ORDER BY `lastname` ASC") or die(mysqli_error());
  48. while($fetch = mysqli_fetch_array($query)){
  49. ?>
  50. <tr class="del<?php echo $fetch['mem_id']?>">
  51. <td><?php echo $fetch['firstname']?></td>
  52. <td><?php echo $fetch['lastname']?></td>
  53. <td><?php echo $fetch['address']?></td>
  54. <td><button type="button" class="btn btn-danger btn_del" id="<?php echo $fetch['mem_id']?>">Delete</button></td>
  55. </tr>
  56. <?php
  57. }
  58. ?>
  59. </tbody>
  60. </table>
  61. </div>
  62. </div>
  63. <script src="js/jquery-3.2.1.min.js"></script>
  64. <script src="js/bootstrap.js"></script>
  65. <script src="js/script.js"></script>
  66. </body>
  67. </html>

Creating the Save Query

This code contains the save function of the application. This code will store the form data to MySQLi database. To make this just copy and write these block of codes below inside the text editor, then save it as save.php.

  1. <?php
  2. require_once 'conn.php';
  3. if(ISSET($_POST['save'])){
  4. $firstname = $_POST['firstname'];
  5. $lastname = $_POST['lastname'];
  6. $address = $_POST['address'];
  8. mysqli_query($conn, "INSERT INTO `member` VALUES('', '$firstname', '$lastname', '$address')") or die(mysqli_error());
  10. header("location: index.php");
  11. }
  12. ?>

Creating the Main Function

This code contains the main function of the application. This code will dynamically delete a table row when the button is clicked. To make this just copy and write these block of codes below inside the text editor, then save it as shown below

  1. <?php
  2. require_once 'conn.php';
  3. $mem_id = $_POST['mem_id'];
  4. mysqli_query($conn, "DELETE FROM `member` WHERE `mem_id` = $mem_id") or die(mysqli_error());
  5. ?>

Note: To make the script works make sure you save this file inside the js directory.

  1. $(document).ready(function(){
  2. $('.btn_del').on('click', function(){
  3. var mem_id = $(this).attr('id');
  4. $.ajax({
  5. type: "POST",
  6. url: "delete.php",
  7. data:{
  8. mem_id: mem_id
  9. },
  10. success: function(){
  11. $(".del" + mem_id).empty();
  12. $(".del" + mem_id).html("<td colspan='5'><center class='text-danger'>Deleting...</center></td>");
  13. setTimeout(function(){
  14. $(".del" + mem_id).fadeOut('slow');
  15. }, 1000);
  16. }
  17. });
  18. });
  19. });
