你可能想使用arg()

Drupal API文檔中提到了arg()函數:「儘可能避免使用此函數,因爲結果代碼很難讀取,而是嘗試在菜單回調函數中使用命名參數。請參閱http://api.drupal.org/api/function/arg/6。 – marcvangend 2010-05-03 19:36:40

您可以使用PA rse_url提取URL的路徑部分,然後您可以從爆炸部件中選取項目。例如:

$x=parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH); 
$y=explode('/',$x); 
$z=$y[2];

在大多數情況下,你可以和應該使用hook_menu處理URL和它的參數。看一看下面的示例代碼,從http://api.drupal.org/api/function/page_example_menu/6採取:

function page_example_menu() { 
    // This is the minimum information you can provide for a menu item. This menu 
    // item will be created in the default menu: Navigation. 
    $items['example/foo'] = array(
    'title' => 'Page example: (foo)', 
    'page callback' => 'page_example_foo', 
    'access arguments' => array('access foo content'), 
); 

    // By using the MENU_CALLBACK type, we can register the callback for this 
    // path but do not have the item show up in the menu; the admin is not allowed 
    // to enable the item in the menu, either. 
    // 
    // Notice that the 'page arguments' is an array of numbers. These will be 
    // replaced with the corresponding parts of the menu path. In this case a 0 
    // would be replaced by 'bar', a 1 by 'baz', and like wise 2 and 3 will be 
    // replaced by what ever the user provides. These will be passed as arguments 
    // to the page_example_baz() function. 
    $items['example/baz/%/%'] = array(
    'title' => 'Baz', 
    'page callback' => 'page_example_baz', 
    'page arguments' => array(2, 3), 
    'access arguments' => array('access baz content'), 
    'type' => MENU_CALLBACK, 
); 

    return $items; 
} 

此功能hook_menu的實現。在這個例子中,註冊了兩個路徑:'example/foo'和'example/baz /%/%'。第一個路徑是一個沒有參數的簡單路徑;當請求時,函數page_example_foo()被調用,不帶參數。第二個路徑是具有兩個參數('參數')的路徑。當請求這條路徑時,Drupal將運行函數page_example_baz($argument1, $argument2)。這被認爲是「正確的方式」,使網址的參數。
