Stupid question about HTML_QuickForm...

Hi, I try PEAR HTML_QuickForm class yesterday & I think it work great for all my purpose BUT I can't figure out how SIMPLY trim() all submit values without overriding éverithing :-(( for sure, I tried to catch at top with this: reset ($HTTP_POST_VARS); while (list ($key, $val) = each ( $HTTP_POST_VARS )) { $$key = munge_space($val); I think then I can't modified special values like $HTTP_*_VARS for security reason but if I can do a stripslashes on it why can't I remove simply space... I also try to trim all inside class with custom method but nothing works *snif* ! also, when I try to addRule on FORM element a second time I got a pear error,. I'd comment the first lines to avoid this without undersatnding why exactly line 507 to line 511 inside QuickForm.php function addRule($element, $message="", $type="", $format="", $validation="server") {

        	#	if (!$this->elementExists($element)) {
          #		return new PEAR_ERROR("Element does not exist in HTML_QuickForm::addRule");
        	#	}

... Maybe I'm stupid, tired or both but, for now I can't find if somebody can help me thanks you Sioui
