我已經在我的形式掛鉤確定的以下內容:的Drupal 7:Ajax表單更新問題
$form['touchpointdivision'] = array(
'#type' => 'select',
'#title' => t('Division'),
'#options' => $divisions,
'#required' => TRUE,
'#ajax' => array(
'event' => 'change',
'wrapper' => 'department-wrapper',
'callback' => 'touchpoints_dept_callback',
'method' => 'replace'
)
);
$form['touchpointdepartment'] = array(
'#type' => 'select',
'#title' => t('Department'),
'#prefix' => '<div id="department-wrapper">',
'#suffix' => '</div>',
'#options' => _get_departments($selected),
'#required' => TRUE
);
這裏的回調:
function touchpoints_dept_callback($form, $form_state){
return $form('touchpointdepartment');
}
當我在第一個下拉列表,我得到改變一個項目以下錯誤:
「致命錯誤:函數名必須是行203 /cmi/sites/all/modules/touchpoints/touchpoints.module字符串」
我在這份聲明中遺漏了什麼?
