[Resolved] How can I prevent these chars {,},[,],<, and > in form text field?

How can I prevent these chars {,},[,],<, and > from being acceptable in a 'text' field in a form?

I tried the following:

if (ereg("([{}[]<>])", $field2, $arr6)) {$clean_up[field2] = $arr6[0];}

but, if these symbols appeared, e.g. at the end of the text, it was ignored.

Thank you.

Try [man]preg_replace[/man] or [man]preg_match[/man]. It's faster than ereg, anyway.

Either way, your preg matching string is:

[FONT=courier new]"/[[]{}<>]/"[/FONT]

for example:
[FONT=courier new]$thestring = preg_replace("/[[]{}<>]/", "", $thestring);[/FONT]

Thank you for your reply.

It works!
