How to check field contents ??

[jeddi]

Hi,

I am getting to much span in my contact form and want to
filter out any messages with a link in them.

I have written this code:

PHP Code:

// Test for link in message.
if($Db_mess  ) {
    $err_msg = "Please do not use links in message."
    require_once ("contact_fm.php");
    exit;
    }  // endif 


I would like to know what test I can use to find
this :[B] [url=[/B]

This is always found in the spam messages.

Thanks for any help.

take a look at preg_match()
http://php.net/manual/en/function.preg-match.php

So this should work then ...

[PHP]

if (preg_match("[url=", $Db_mess)) { // Test for link in message.
$err_msg = "Please do not use links in message."
require_once ("contact_fm.php");
exit;
} // endif
[/PHP]

Thanks for the help.
