Using the *horizontal or *vertical layout works fine, but I need a more customized layout. What would be useful is if an array could be passed to the template instead of the particular multiple variables.

eg instead of $label_checkbox_1 and $checkbox_1 etc could we please get $label_checkbox['1'] and $checkbox['1']. That way we could simple foreach through the array.

The problem is that if client-side validation is done and ok, the form will submit but in PHP you will not know which elements were hidden BUT you know all the values that were submitted. So, the trick is that when you create the form, attach rules based on value of $_POST like:

// we have a random checkbox
$form->add('checkbox', 'mycheckbox', 1);

// this second checkbox is required only if the first one is
// selected; whether this checkbox is visible or not is
// controlled from jQuery
$obj = &$form->add(
  'checkbox',
  'myothercheckbox',
  2,
  array('style' => 'display:none')
);

if (
  isset($_POST['mycheckbox']) &&
  $_POST['mycheckbox'] == 1
) {

  $obj->set_attributes(array('style' => 'display:block'));

  $obj->set_rule(array(
    'required' => array('error', 'Some error');
  ));

);

I hope this makes sense

I need to use a custom form with dynamic checkboxes but cannot work out how to display them.

ie I have $label_checkbox_1 and $checkbox_1 but I might also have $label_checkbox_2 and $checkbox_2 or $label_checkbox_5 and $checkbox_5

this thing would be great i think ( or maybe i have missed this functionnality ^^)

The problem is with validation. If the first option is selected, then I’d like the second appearing select box to be required. If the second option is selected, then I’d like both appearing text boxes to be required. I can set the validation rule for all of them to be required initially, but when the form is submitted, even if one of these controls is still hidden, then it generates a validation error. So what I’d like to do is be able to set a validation rule for a control when it’s visible and remove it when it’s not. You’re doing something similar with the ‘other’ text box that appears when Other… is selected from a select box. Can I do something similar as I’ve described? Or can I use javascript to get at your validation_rules object so I can set and unset rules dynamically? Thanks for any thoughts you might have. I appreciate how good you are about responding to these things. -Edward.
