This code contains the php query of the application. This code will save the data inputs to the MySQLi database server. To do that just copy and write this block of codes inside the text editor, then save it as insert.php.

  1. <?php
  2. require_once 'conn.php';
  3.  
  4. $firstname = $_POST['firstname'];
  5. $lastname = $_POST['lastname'];
  6. $address = $_POST['address'];
  7.  
  8. mysqli_query($conn, "INSERT INTO `member` VALUES('', '$firstname', '$lastname', '$address')") or die(mysqli_error());
  9.  
  10. header("location: index.php");
  11. ?>

Creating the Main Function

This code contains the main function of the application. This code will delete a MySQLi data 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 delete.php

  1. <?php
  2. require_once 'conn.php';
  3.  
  4. if(ISSET($_REQUEST['mem_id'])){
  5. $id=$_REQUEST['mem_id'];
  6. mysqli_query($conn, "DELETE FROM `member` WHERE `mem_id`='$id'") or die(mysqli_error());
  7. header("location:index.php");
