multi functions against user input - help

[Fritz]

I am new to functions and am trying to clean up ALL fields from a form... I can get this to effect all fields but If I try to add a second function THAT function doesn't effect anything...

any examples of how to do multi-functions against all input fields would be extremely appreciated.

here what I have

<? // [cleanup.inc] : Clean form text on input.

function clean_input ()
{ foreach ($_POST as $key => $value) 

{ $_POST[$key] = strip_text ($value); }

}

function strip_text ($text)
/* Do your cleaning/stripping functions here.  Actual text cleanup, etc. */

{ return str_replace ("badword", "*CENSORED*", $text); 

return str_replace ("damn", "***You can say Damn***", $text); } ?>

?>[/code]

Well you've got 2 return()'s in your second function, one after the other. Do you realise that your program will always return after the first return(), and the second return() won't even be processed?

I clearly haven't a clue as to how to do a second function that will apply to all form fields...

any expamples would be highly appreciated.

I think that instead of having

return str_replace ("badword", "*CENSORED*", $text);

return str_replace ("damn", "***You can say Damn***", $text);

you should have

$text = str_replace ("badword", "*CENSORED*", $text);
$text = str_replace ("damn", "***You can say Damn***", $text);
return $text;
