Question

Notice: Undefined index: id in C:\xampp\htdocs\project\Book_store\admin\process_del_book.php on line 4

<?php
require('includes/config.php');

$query="delete from book where b_id =".$_GET['id'];

mysqli_query($conn,$query) or die("can't Execute...");

header("location:all_book.php.php");

?>

Answer 1

Check if the $_GET['id'] is set

if(isset($_GET['id'])) {
$query="delete from book where b_id =".$_GET['id'];
}

Undefined index means that you are trying to access data in array that doesn't exist.

Answer 3

When you call the $_GET super global variable it retrieves variables from the url of the page (like anything after the ? located after the page name.) You need to make sure that there is something that says id=someValue. If not it will not work
