hi

are you trying something like this

<?php

$connection = mysql_connect('localhost', 'username', 'password');

$sql = mysql_select_db('db1', $connection);

$userid = "Snib";

$query = "SELECT * FROM `table1` WHERE userid='$userid'";

$result = mysql_query($query);

$data = mysql_fetch_assoc($result);

$usernum = $data['usernum'];

?>



<script language="javascript" type="text/javascript">

var userid = "<?php echo $userid; ?>";

var usernum = "<?php echo $usernum; ?>";

//if usernum is less than or equal to 50
if (usernum <= 50) {

alert("You are not allowed on this page, " + userid);
setTimeout('window.location = "otherpage.php"', 3000); // user leaves in 3 seconds

} else {

alert('Welcome to this page, ' + userid);

}

</script>

<?php mysql_close($connection); ?>

Try this code
Regards

Ajax only calls javascript functions which are client side. If you need to access the variable, you must write it and asign it to a javascript variable. If you use ajax to load another php page behind the scenes, you'll need to return the variable as part of the response text
