But you'd better make a distinction between the elements and their attributes. You could probably do something like this: $txtAttributes = array( 'maxlength' => 30, 'style' => 'border: 1px solid #FFCCCC;'); Then your elements : $elementArr = array('name' => 'test1', 'type' => 'text', 'attributes' => $txtAttributes, 'rule' => 'required', 'rulemsg' => 'element is required' ...); Probably, you will make a big array with all your element arrays. then with your own parser (a foreach loop), you walk the elements array and when you meet a new element you do $form->addElement($name, $type, $label, $attributes); and if you want some rules, you just do $form->addRule($name, $rule, $rulemsg); BTW, QuickForm elements all extend HTML_Common which has the following methods : - setAttributes - updateAttributes - removeAttribute and so on... This way, you can do: $myelement->setAttributes( array or string of attributes) whenever you want to modify your element. Methods like setMaxlength, setSize and the rest are just convenience accessors to make it easier to set these default parameters. All in all, what you want to do is really possible with QuickForm but will require a bit more effort from the beginning by working on your parser and calling the right methods. If I were you, I would also use a form object. I would create a new form object, then create my elements individually, then call $myFormObject->addElement($myElement); just to make sure values and validation work. I don't think it is possible to validate an element when it is not in a form object. Bertrand Mansion Mamasam
