Blocking Form Spam

[kruser]

Hello,

I have a form that someone is passing undesirable content with. I have tried to remove the "[ ]" brackets using php string replace , but the bad content & brackets are still getting passed.

This is a piece of what is being passed.

Does anyone know how to handle this?

It seem there is a problem with your replace code. can you post it here to check it for you.
you can also use regular expressions to strict inputs to certain pattern. like numbers or letters only or both.

brackets should be able to be removed using:

$string = ereg_replace('[\[\]]', '', $string);
