Creating the PHP Query
This code contains the php query of the application. This code will store the data inputs to the database server. To do that just copy and write this block of codes inside the text editor, then save it as save_member.php.- <?php
- require_once 'conn.php';
- $firstname = $_POST['firstname'];
- $lastname = $_POST['lastname'];
- $age = $_POST['age'];
- $address = $_POST['address'];
- mysqli_query($conn, "INSERT INTO `member` VALUES('', '$firstname', '$lastname', '$age', '$address')") or die(mysqli_error());
- }
- ?>
Creating Main Function
This code contains the main function of the application. This code can remove and restore the data when the button is clicked. To do that just copy and write this block of codes inside the text editor, then save it as shown below. remove.php- <?php
- require_once 'conn.php';
- $mem_id = $_REQUEST['mem_id'];
- $query=mysqli_query($conn, "SELECT * FROM `member` WHERE `mem_id` = '$mem_id'") or die(mysqli_error());
- mysqli_query($conn, "INSERT INTO `trash` VALUES('', '$fetch[mem_id]', '$fetch[firstname]', '$fetch[lastname]', '$fetch[age]', '$fetch[address]')") or die(mysqli_error());
- }
- ?>
- <?php
- require_once 'conn.php';
- $trash_id = $_REQUEST['trash_id'];
- $query=mysqli_query($conn, "SELECT * FROM `trash` WHERE `trash_id` = '$trash_id'") or die(mysqli_error());
- mysqli_query($conn, "INSERT INTO `member` VALUES('', '$fetch[firstname]', '$fetch[lastname]', '$fetch[age]', '$fetch[address]')") or die(mysqli_error());
- }
- ?>
