Question

In my product.php I give the user the opportunity to add or remove a deal in his wishlist.
I did it using AJAX and an external file that added his id and product id but I don’t want it with AJAX.

What is another way to run this SQL query in PHP when a button or a link or image is clicked? I don’t mind if the page is refreshed.

$query = "DELETE FROM relations WHERE user_id = '$myid' and deal_id = '$dealid'";
mysql_query($query);
mysql_close();

Answer 1

With a simple link?

<a href="delete-deal.php?dealid=42">Delete</a>

delete.php would look like something this:

<?php

/* mysql connection code here */

$myid = /* get myid somehow */
$dealid = (int)$_GET['dealid'];

$query = "DELETE FROM relations WHERE user_id = '$myid' and deal_id = '$dealid'";
mysql_query($query);
mysql_close();

header('Location: http://example.com/page/to/go/back/to');
