drupal塊variable_set不保存選擇值

我想創建一個塊來保存選擇框中的值。但是，重新加載後，variable_get不會返回保存的值...所以variable_set接縫不能工作。drupal塊variable_set不保存選擇值

我在這裏做錯了什麼？（Drupal的6）

function get_courses(){ 
    global $user;  
    $my_items_sql = 'SELECT course_node.uid, '; 
        //get the course nid 
        $my_items_sql .='course_node.nid as course_nid, '; 
        //get the course title 
        $my_items_sql .='course_node.title as course_title '; 
        $my_items_sql .=' from node as course_node where course_node.type="course" and course_node.uid = "'.$user->uid.'"'; 
        $my_items_sql .=' order by course_node.nid; '; 
        $my_items_data= db_query($my_items_sql); 

        $my_courses = array(); 
        while ($row = db_fetch_array($my_items_data)) { 

          //$course_node = node_load($row["course_nid"]); 
          $my_courses[$row["course_nid"]]=$row["course_title"]; 
        } 
        //$variables['courses']=$my_courses; 
        //drupal_add_js(array('courses'=>$my_courses), "setting"); 

     return $my_courses; 
} 
function front_page_block($op='list',$delta = 0, $edit = array()) { 

    $course_options = array(); 
    $courses = get_courses(); 
    $tmp = $courses; 
    $first_course = $tmp; 
    reset($first_course); 
    $first_course_nid = key($first_course); 

    $first_course_nid = key($first_course); 
    switch($op){ 
     case 'list': 
      $blocks[0]['info']= t('Course Data Loader'); 
      $blocks[0]['cache']= BLOCK_NO_CACHE; 
      return $blocks; 
     case 'configure': 
      $form['course_to_display'] = array(
      '#type' => 'select', 
      '#description' => t('Display flashcards from which deck on the front page?'), 
      '#options' => $courses, 
      '#default_value'=>variable_get('front_page_deck_to_load', $first_course_nid) 
      ); 
      return $form; 
     case 'save': 
      variable_set('front_page_deck_to_load', 
       $edit['front_page_deck_to_load']); 

      break; 


    }

首先檢查一下，有什麼值設置爲$編輯[ 'front_page_deck_to_load']，前致電

variable_set（ 'front_page_deck_to_load'，$編輯[ 'front_page_deck_to_load' ]）;功能。

如果$ edit ['front_page_deck_to_load']的值設置正確，那麼variable_set正在工作。

現在的問題是，在'#default_value' 的$形式[ 'course_to_display']設置不正確。請修改get_courses（）功能如下，然後再試一次：FYI

function get_courses(){ 
    global $user;  
    $my_items_sql = 'SELECT course_node.uid, '; 
        //get the course nid 
        $my_items_sql .='course_node.nid as course_nid, '; 
        //get the course title 
        $my_items_sql .='course_node.title as course_title '; 
        $my_items_sql .=' from node as course_node where course_node.type="course" and course_node.uid = "'.$user->uid.'"'; 
        $my_items_sql .=' order by course_node.nid; '; 
        $my_items_data= db_query($my_items_sql); 

        $my_courses = array(); 
        while ($row = db_fetch_array($my_items_data)) { 

          //$course_node = node_load($row["course_nid"]); 
          $my_courses[$row["course_title"]]=$row["course_title"]; 
        } 
        //$variables['courses']=$my_courses; 
        //drupal_add_js(array('courses'=>$my_courses), "setting"); 

     return $my_courses; 
}
