Question

Basically as my question stated, it works on phpmyadmin but not php itself. When I run the script, it returns true, and doesn’t die. HELP!

here is the query:

DELETE FROM selections WHERE selectorID = '$userID' AND selectedID = '$ID'

Here is the php script:

<?php

include_once "connect_to_mysql.php";

$errorB = false;

$error = '';
$id = '';
$userID = '';
if (empty($_GET['ID']) || empty($_GET['userID'])) {
$errorB = true;

if (empty($_GET['ID'])) {
    $error = $error.'-No selected ID was sent';

}

if (empty($_GET['userID'])) {
    $error = $error.'-No selector ID was sent';

}


} else {
$id = $_GET['ID'];
$userID = $_GET['userID'];
echo $id.$userID;
$sqlInsert = mysql_query("DELETE FROM selections WHERE selectorID = '$userID' AND selectedID = '$ID'") or die (mysql_error());
echo 'shz';
}

if ($errorB) {
echo $error;

}



?>

My database looks like this:

 id|selectorID|selectedID
 3  1          4
 4  1          5

Your first, but lesser trouble is the case sensitive nature of PHP variables:

Here

$sqlInsert = mysql_query("DELETE FROM selections WHERE selectorID = '$userID' AND selectedID = '$ID'") or die (mysql_error());

you refer to $ID, but have only $id:

$id = $_GET['ID'];

Correctly:

$sqlInsert = mysql_query("DELETE FROM selections WHERE selectorID = '$userID' AND selectedID = '$id'") or die (mysql_error());

IMPORTANT NOTE

While this will most likely work, but this is prone to SQL injection! Use PDO instead, or at the very least, escape your values!!!
