Help: Invalid url php help...

I have some code,

$number = urldecode( $_GET['id'] );

Which gets the id from the url, ('/GAMETAB/template.php?&id=')

but you can change this manually...

to like '/GAMETAB/template.php?&id=200000'

Which would be invalid.

Is there any to put, if the 'id' number isnt in the table/database, it will redirect you to an error page, or something?

Is this possible?

Please comment...

 

$number = urldecode( $_GET['id'] );

Search $number in you database
if ($number NOT found) {
echo "Invalid";
} else {

....

Is this what you need or Im missing something here...?

 

Perfect thanks.

 

Working

 

<?php
// inval() is for security.
$number = intval($_GET['id'])
require_once(db_config.php);

$queryGetGames = mysql_query("SELECT * FROM table_perfix WHERE id = '$number' ");
$numGames = mysql_num_rows($queryGetGames);

if($numGames == 0){
echo "NO GAMES WERE FOUND";
exit;
}
else{
// your code here..
}

?>

Code (markup):

Please notice that inval cannot deal with numbers bigger than 2147483647.
Good Luck.
