Is there a way to disable or hide/show XoopsForm elements at runtime?

I've got a form that contains time info: Time starts with a XoopsFormDateTime element and has a duration that is set with a collection of radio buttons. But if the radio button "Custom" is chosen I'd like the user to set the duration in a new XoopsFormDateTime control that either has to become enabled or visible (if it's been hidden so far).

This is easily done with "onclick" javascript if I do things from scratch, but is it possible to do this using XoopsForms?

You can use the XoopsFormElement::setExtra method:

$xoopsOption['template_main'] = 'template filename';
require_once 
XOOPS_ROOT_PATH '/header.php';
require_once 
XOOPS_ROOT_PATH '/class/xoopsformloader.php';
...
$form = new XoopsThemeForm('form title''form1', ...);
...
$element = new XoopsFormRadio(...);
...
$element->setExtra("onClick = func;");
$form->addElement($element);
...
$xoopsTpl->assign('form_validation_js'$form->renderValidationJS());
$form->assign($xoopsTpl);
...
require_once 
XOOPS_ROOT_PATH '/footer.php';


The Javascript function "func" would go in the template.

Thanks!!! How come the only way to figure this out is to ask?

Uh, sorry, some additional questions popped up here:

I want to hide an element within a form, which means I need to know the ids of the elements... Nope! I need a way to set the id of the <-tr-> tag that contains the element that I want to hide, right? Or else I get empty rows in the form, and I don't want that. But:

1. I can't find a way to give the <-tr-> that contains the element an id. Is this possible? - or -

2. I know that the element I want to hide is inside the following <-tr->. This means that I could search for it in the DOM. Am I on the right track?

3. Would it be easier if I start using a javascript library like Prototype for stuff like this? Any recommendations?


BTW, how do I write tags in this forum without messing up the layout?

why can't you use an 'IF' clause to hide the element?

if you set that up in the .php files

if(isset($element)) {
}


or even with smarty

<{if $element !== ''}>
<{/if}>

No, that would take a reload if I want to toggle show/hide (please correct me if I'm wrong). I want to do it at runtime, which means there's got to be some javascript involved (again, please correct me )

yes, you're right..

for a +/- toggle to hide/view etc, yes you will need some javascript.
