我是drupal的新手。我正在使用 drupal 7 中的代码创建自定义 url，我想设置自定义 url。我正在使用以下代码。目前它正在显示网址 http://abc.com/greeting-12 我想设置它http://abc.com/ab/cd/md5(string) 请让我知道我该怎么做？
<?php
drupal_add_css(drupal_get_path('theme', 'custom') . '/css/my_flip1.css', array('group' => CSS_THEME, 'type' => 'file'));
$path = base_path() . path_to_theme();
?>
<?php
global $url;
$link_id=$_REQUEST['link_id'];
global $myimg;
global $de;
if(isset($_REQUEST['id']))
{
global $myimg;
global $de;
global $url;
$myimg=$_REQUEST['img'];
$path = base_path() . path_to_theme();
$account = $GLOBALS['user']->uid;
$de=$_REQUEST['txt'];
$node=new stdClass();
$node->type = "page"; // Or any other content type you want
$title=$node->title="Greeting";
$node->language = LANGUAGE_NONE;
node_object_prepare($node); // Set some default values.
$node = node_submit($node); // Prepare node for a submit
node_save($node); // After this call we'll get a nid
$node->status = 1;
$options = array('absolute' => TRUE);
$nid =$node->nid;
$url = url('node/' . $nid, $options);
$node->path=$url;
db_insert('user_shared_image')
->fields(array(
'uid' => $account,
'link' => $node->path,
'description'=>$_REQUEST['txt'],
'link_id'=>$link_id,
))
->execute();
$format = '
