Help: something's wrong, but I cant find the error

[clown[NOR]]

everytime a user who's logged in refreshes the control panel, I need to update the timestamp in the database for the user... but it wont update... can anyone see what might be causing it?

 

this is the validation function I run on top of every page:

<?php

function valUser($epost)
{
	$axx = $_COOKIE['axx'];
	$sid = $_COOKIE['sid'];
	if (!empty($axx) && !empty($sid)) {
		c2db();
		$epost = secureSQL($epost);
		$axx = secureSQL($axx);
		$sid = secureSQL($sid);
		$query = "
			SELECT * FROM `news_users` WHERE
				`email` = '".$epost."'
			AND
				`access` = '".$axx."'
			AND
				`sid` = '".$sid."'
			AND
				`authorized` = '1'
			LIMIT 1
		";
		$result = mysql_query($query);
		if (!$result) { die(mysql_error()); }

		$dbRows = mysql_num_rows($result);
		if ($dbRows == 1) {
			$dbField = mysql_fetch_array($result);
			$last_active = strtotime($dbField['timestamp']);
			$idle = strtotime(date("Y-m-d H:i:s", strtotime("5 minutes ago")));
			if ($idle > $last_active) {
				setcookie("epost", "", time()-3600);
				setcookie("axx", "", time()-3600);
				setcookie("sid", "", time()-3600);
				return 0;
			} elseif ($idle < $last_active) {
				updateTimestamp($epost,$axx,$sid);
				return 1;
			}
		} else { header("Location: index.php"); }		

	}

}

?>

 

this is the updateTimestamp() function

<?php
function updateTimestamp($epost,$axx,$sid)
{

	c2db();
	$new_time = secureSQL(date("Y-m-d H:i:s"));
	$epost = secureSQL($epost);
	$axx = secureSQL($axx);
	$sid = secureSQL($sid);
	$query = "
		UPDATE `news_users` SET 
			`timestamp` = '".$new_time."'
		WHERE
			`email` = '".$user."'
		AND
			`sid` = '".$sid."'
		AND
			`access` = '".$axx."'
		LIMIT 1
	";
	$result = mysql_query($query);
	if (!$result) { die(mysql_error()); }

	setcookie("epost", "", time()-3600);
	setcookie("axx", "", time()-3600);
	setcookie("sid", "", time()-3600);
	setcookie("epost", $epost, time()+3600);
	setcookie("axx", $axx, time()+3600);
	setcookie("sid", $sid, time()+3600);
}
?>

 

this is what I run on top of every page

<?php
if (isset($_COOKIE['epost']) && !empty($_COOKIE['epost'])) {
	$epost = $_COOKIE['epost'];
	$valUser = valUser($epost);
	if ($valUser == 0) { header("Location: index.php"); }
} else { header("Location: index.php"); }
?>

 

Thanks In Advance

Did you puke out the query?  What's it look like?

[clown[NOR]]

what you mean?

[Wildbug]

Did you output the query that is assembled in your script to see that it's correct?

 

Also, have you checked for any mysql_error()s?

[sasa]

where you set variable $user? (function updateTimestamp())
