[QuickForm][Controller/Page] register(methodic)Rule();

!Buenas dias! I am trying to use a custom rule in my QuickForm which is inside of a QF_Page-class. As probably anyone I want to group my special rules in a special class to be able to reuse them. Here is a simplified version of this rulelib with just one rule :) <?php class customRules { function superCheck($element,$val) { if(isset($val)==1) { $ret = '1'; } else { $ret = '0' } return $ret; } } ?> this is the code inside my form (see above) which tries to validate the form. It seems like the registration is well done, but for some unknown reason i always get strange return-values which forces the QuickForm-object to react not I expected it to do. <?php // .. class definitions.. // add element $list_sixMAgo[] = &HTML_QuickForm::createElement('radio', null, null, 'Yes', '1'); $list_sixMAgo[] = &HTML_QuickForm::createElement('radio', null, null, 'No', '0'); $this->addGroup($list_sixMAgo, 'sixMAgo', 'Uhh.. something went very very wrong..'); // register custom rules $customRules = new customRules(); // necessary or will registerRule()-method call the method from the (available) class (statically)? $this->registerRule('superCheck','function','superCheck','customRules'); // add rule // $this->addRule('sixMAgo', 'please click this, baby!', 'superCheck'); // ..more stuff.. ?> Whats my fault? Thank you in advance! --M PS: Something different: Is it possible that the renderer SmartyDynamic (which i found on the web) is identical with the bundled QuickForm_Renderer_Array?
