[英]migrating from drupal 6 to drupal 7 form_alter hook is throwing an error - Notice: Undefined index: buttons in sport_utils_form_alter()
我正在從Drupal 6
升級到Drupal 7
。 我在更新后啟用了此模塊。
這是我的功能:
function sport_utils_form_alter($form, $form_state, $form_id) {
if (strpos($form_id, '_node_form') !== FALSE) {
$form['#validate'][] = 'byu_sport_utils_verify_valid_author';
$form['#validate'][] = 'byu_sport_utils_remove_first_line_break';
$form['top_buttons'] = $form['buttons'];
$form['top_buttons']['#weight'] = -500;
$form['top_buttons']['#prefix'] = $form['buttons']['#prefix'] = '<div class="button-bar">';
$form['top_buttons']['#suffix'] = $form['buttons']['#suffix'] = '</div><div class="clear"></div>';
}
}
它在此行上引發錯誤:
$form['top_buttons'] = $form['buttons'];
我不知道是否需要用在Drupal 7中可用的其他東西替換$form['buttons']
。
有什么建議么?
在Drupal 7中,表單按鈕被分組在$form['actions']
。 因此,您需要修改代碼以支持如下所示的代碼。
function sport_utils_form_alter($form, $form_state, $form_id) {
if (strpos($form_id, '_node_form') !== FALSE) {
$form['#validate'][] = 'byu_sport_utils_verify_valid_author';
$form['#validate'][] = 'byu_sport_utils_remove_first_line_break';
/**
* Copy the action buttons (submit, preview, etc ..)
* and place them at the top of the form
*/
if(!empty($form['actions'])) {
$actions = element_children($form['actions'], TRUE);
foreach($actions as $name) {
$form['top_buttons']["$name-top"] = $form['actions'][$name];
}
}
$form['top_buttons']['#weight'] = -500;
$form['top_buttons']['#prefix'] = $form['actions']['#prefix'] = '<div class="button-bar">';
$form['top_buttons']['#suffix'] = $form['actions']['#suffix'] = '</div><div class="clear"></div>';
}
}
