【问题描述】:
我在使用 hook_theme 为特定表单自定义单选按钮时遇到问题。下面是我的模块上的一段代码;请参阅我的 cmets 详细说明我遇到的问题:
// Implementation of hook_form_alter().
function mymodule_form_alter(&$form, $form_state, $form_id){
// e.g form id: commerce_cart_add_to_cart_form_u6onPJSgS7pOgw0Tlo7zHy42LTQzbV913taANkYQKTo
if (strpos($form_id, 'commerce_cart_add_to_cart_form') !== FALSE) {
// Alter add to cart form
mymodule_commerce_cart_add_to_cart_form_alter($form, $form_state, $form_id);
}
}
function mymodule_commerce_cart_add_to_cart_form_alter(&$form, $form_state, $form_id) {
// Change the field type to radios.
$form['attributes']['field_artwork_ref']['#type'] = 'radios';
// Apply my custom theme for radios.
$form['attributes']['field_artwork_ref']['#theme'] = array('custom_radios');
}
// Implementation of hook_theme().
function mymodule_theme() {
return array(
'custom_radios' => array(
'variables' => array('element' => NULL),
),
);
}
function theme_custom_radios($variables) {
// Custom theme should go here.
// However, $variables are empty, print_r gives me "Array ( [element] => )."
// I am at least expecting to see my radio element here.
print_r($variables);
}
