İşte benim örnek (kullanarak #after_build
):
$form['legal']['legal_accept']['#type'] = 'checkboxes';
$form['legal']['legal_accept']['#options'] = $options;
$form['legal']['legal_accept']['#after_build'][] = '_process_checkboxes';
Ayrıca aşağıdaki işlev geri çağrısı:
function _process_checkboxes($element) {
foreach (element_children($element) as $key) {
if ($key == 0) { // value of your checkbox, 0, 1, etc.
$element[$key]['#attributes'] = array('disabled' => 'disabled');
// $element[$key]['#theme'] = 'hidden'; // hide completely
}
}
return $element;
}
Drupal 6'da test edildi ancak Drupal 7 için de çalışması gerekiyor.
