Drupal 7：如何在添加内容时仅允许选择分类项目的子级别作为类别

Question

我有一个基于分类的具有类别字段的内容类型。但我希望编辑只能选择每个内容片段的子类别，而不是父类别。我怎么做？

我有类似这样看，如果可以帮助你在某种代码...它得到孩子的家长在一个数组，如果你打算使用自定义模块，使之...

$tree_type = taxonomy_get_tree(3); 
    $childs["selected"]="All"; 

    foreach($tree_type as $key =>$value) { 
       $temp_ = taxonomy_term_load($value->parents[0]);   //IF parent is set already 
      if($value->parents[0]==0) {        //if no any parent taxonomy 
        if(is_object($temp_)==TRUE) {     //CHECK IF SINGLE iTEM PARENT 
        if(isset($childs[$temp_->name])) {   //if array key is already set 
          if(is_array($key)!=FALSE) {   //if value is not an array 
        $childs[$temp_->name][$tree_type[$key]->tid]=array($key=>$value->name); // set the parent child array 
          } 
        }else { 
          if(is_array($key)!=FALSE) { //if value is not an array 
        $childs[$temp_->name][$tree_type[$key]->tid]=array($key=>$value->name); // set the parent child array 
          } 
         } 
        }else 
        { 
         $childs[$value->name]=array(); 
         $childs[$value->name][$tree_type[$key]->tid]="-".$value->name; 
         //drupal_set_message("-------<pre>".$value->name."</pre>-------"); 
         //drupal_set_message("<pre>".print_r($childs,true)."</pre>"); 
         } 
       }else { 
     $childs[$temp_->name][$tree_type[$key]->tid]=$value->name;   //$childs[$temp_->tid]=$temp_->name; 
       } 
     }
