[Activation]

I can't seem to get my activation link (code) to properly activate the link. I had a lot of trouble debugging it, but once I finished with that, the code runs through, and it keeps saying, "Your account could not be activated. Please re-check the link or contact the administrator." I can't tell what is failing though? Does my code look alright? I am almost sure that my database is correct.

 

Here is the main body of my code:

 

 

<?php

if (isset($_GET['x'], $_GET['y']) && filter_var($_GET['x'], FILTER_VALIDATE_EMAIL) && (strlen($_GET['y']) == 32 )) {

require (MYSQL);
$q = "UPDATE users SET active=NULL WHERE email=' " . mysqli_real_escape_string($dbc, $_GET['x']) . "' \n"
. "\n"
. "AND \n"
. " \n"
. "active=' " . mysqli_real_escape_string($dbc, $_GET['y']) . "' \n"
. "\n"
. "LIMIT 1";

$r = mysqli_query ($dbc, $q) or trigger_error("Query: $q\n<br />MySQL Error: " . mysqli_error($dbc));

if (mysqli_affected_rows($dbc) == 1) {
echo "<h3>Your account is now active; log in at any time.</h3>";

} else {
echo '<p class="error">Your account could not be activated. Please re-check the link or 
contact the administrator.</p>';
}

mysqli_close($dbc);

} else {

$url = BASE_URL . '/index.php';
ob_end_clean();
header("Location: $url");
exit();
}

?>

 

I know that my query is written very oddly. I wrote it like that because it kept feeding me errors and I just wanted it to work for now, so I fed it in very discretely.

 

Any help would be greatly appreciated.
