我试图弄清楚我试图在 Drupal 7 中工作的这段 Drupal 6 php 代码有什么问题:
function node_widget_get_fields(&$form) {
$fields = array();
if (isset($form['#type'])) {
$content_type = content_types($form['#type']['#value']);
foreach ($content_type['fields'] as $field_name => $field) {
if ($field['type'] == 'nodereference' && $field['widget']['type'] ==
'node_widget_node_form') {
$fields[$field_name] = $field;
}
}
}
return $fields;
这是我已经走了多远:
function node_widget_get_fields(&$form) {
$fields = array();
if (isset($form['#type'])) {
$content_type = field_info_instances($form['#type']['#value']);
foreach ($content_type['fields'] as $field_name => $field) {
if ($field['type'] == 'nodereference' && $field['widget']['type'] ==
'node_widget_node_form') {
$fields[$field_name] = $field;
}
}
}
return $fields;
返回的错误:
