Although I can see the use of is_numeric(), I hardly ever use it. Hold on! Before you think I'm insane, let me explain why. Most of the time, when I'm dealing with a numeric input, it's most likely an auto incremented unsigned integer. I'm not sure about other databases, but MySQL starts numbering those columns at 1, so I just intval the incoming variable and handle it at the same time as I would catch an unset or 0 value. ----- You also can use this for SQL queries: $sql=sprintf("SELECT * FROM table WHERE id='%d';", $id); It only accept numeric stuff, and if you try to input some string it will return false (zero), and that's it.. - http://Kmos.TondelaOnline.com - I'm a lost soul in this lost world... ---- Manual Page -- http://www.php.net/manual/en/security.database.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+37591 Delete -- http://master.php.net/manage/user-notes.php?action=delete+37591&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+37591&report=yes Search -- http://master.php.net/manage/user-notes.php
