Buat bidang Referensi Entitas dengan konfigurasi default
Function entitasreference_autocomplete_callback_get_matches menentukan output dari autocomplete.
function entityreference_autocomplete_callback_get_matches($type, $field, $instance, $entity_type, $entity_id = '', $string = '') {
$matches = array();
$entity = NULL;
if ($entity_id !== 'NULL') {
$entity = entity_load_single($entity_type, $entity_id);
$has_view_access = (entity_access('view', $entity_type, $entity) !== FALSE);
$has_update_access = (entity_access('update', $entity_type, $entity) !== FALSE);
if (!$entity || !($has_view_access || $has_update_access)) {
return MENU_ACCESS_DENIED;
}
}
$handler = entityreference_get_selection_handler($field, $instance, $entity_type, $entity);
if ($type == 'tags') {
// The user enters a comma-separated list of tags. We only autocomplete the last tag.
$tags_typed = drupal_explode_tags($string);
$tag_last = drupal_strtolower(array_pop($tags_typed));
if (!empty($tag_last)) {
$prefix = count($tags_typed) ? implode(', ', $tags_typed) . ', ' : '';
}
}
else {
// The user enters a single tag.
$prefix = '';
$tag_last = $string;
}
if (isset($tag_last)) {
// Get an array of matching entities.
$entity_labels = $handler->getReferencableEntities($tag_last, $instance['widget']['settings']['match_operator'], 10);
// Loop through the products and convert them into autocomplete output.
foreach ($entity_labels as $values) {
foreach ($values as $entity_id => $label) {
$key = "$label ($entity_id)";
// Strip things like starting/trailing white spaces, line breaks and tags.
$key = preg_replace('/\s\s+/', ' ', str_replace("\n", '', trim(decode_entities(strip_tags($key)))));
// Names containing commas or quotes must be wrapped in quotes.
if (strpos($key, ',') !== FALSE || strpos($key, '"') !== FALSE) {
$key = '"' . str_replace('"', '""', $key) . '"';
}
/* *** */$matches[$prefix . $key] = '<div class="reference-autocomplete">' . $label .' - ('. $entity_id . ')</div>';//****
}
}
}
drupal_json_output($matches);
}
baris terakhir $matches[$prefix . $key] = '<div class="reference-autocomplete">'menentukan output dan $entity_idtersedia yang merupakan ID. Anda dapat melakukan apa yang saya lakukan di baris itu (ditunjukkan oleh **), cukup tulis:
$matches[$prefix . $key] = '<div class="reference-autocomplete">' . $label .' - ('. $entity_id . ')</div>';
Anda dapat menggunakan $entity_iduntuk mengambil bidang lain dan apa pun yang Anda inginkan.
Satu hal lagi!
Beberapa kali itu bukan ide yang baik untuk mengubah fungsi modul inti (jika tidak penting bagi Anda solusi di atas sudah cukup).
Jika Anda perlu mengganti fungsi inti entity_referencemodul, buat modul kecil dan beri namaelabel
ini elabel.info
;$Id;
name = My Entity Reference Label
description = This module creates special Entity Reference Label
package = My Modules
core = 7.x
php = 5.1
files[] = elabel.module
dan itu elabel.module

Saya mencoba kode ini dan berfungsi dengan baik Jika ada jenis referensi entitas lain dan Anda tidak perlu melakukan ini untuk mereka, cukup tambahkan IFpernyataan dan periksa bundel atau tipe konten.
