This post is the second part of Create Drupal form using theme_table() like module list form post. In first part I have showed how we can create Drupal form like we have in Module list pages. In this post, I am showing how we disable some of the checkboxes so user can’t select them like we have for core modules in module list page. We can’t enable/disable core modules in module list.

Drupal Form using theme_table() function (Part II)

Here I am just showing the changes which we require in code of Part I post.

 $form['featured'] = array(
    '#type' => 'checkboxes',
    '#options' => $options,
    '#default_value' => $status,
);
 
// Change this to 
 
$form['featured'] = array(
    '#type' => 'checkboxes',
    '#options' => $options,
    '#default_value' => $status,
    '#process' => array(
        'expand_checkboxes',
        'featured_disable',
        ),
    '#disabled_products' => $disabled,
);

In above code “$disabled” is an array containing the productid’s of all the products which we want to show as checked and in disable state. The structure of “$disabled” array is similar to “$status” array. We stored this array in “#disabled_products”. We also added “#process” in above code.

“expand_checkboxes” and “featured_disable” are function names which Drupal call when create and render these checkboxes. “expand_checkboxes()” is defined in Drupal core files and we don’t need to define it again.

function featured_disable($form, $edit) {
  	foreach ($form['#disabled_products'] as $key) {
  		$form[$key]['#attributes']['disabled'] = 'disabled';
  	}
 
  	return $form;
}

“featured_disable()” function is very important here. Drupal call this function when renders these checkboxes. Here we assigned “disabled” attribute to each checkbox which we want as disable.
