magento - 检索给定类别ID的所有子类别

As said in the title, i'm trying to do this stuff through my custom function:

public function retrieveAllChilds($id = null, $childs = null){

        $childIdsArray = is_null($childs) ? array() : $childs;
        $category = is_null($id) ? $this->getCurrentCategory() : $this->getCategoryFromId($id);
        if (count($this->getChildrenCategories($id)) > 0) {
            $c = count($this->getChildrenCategories($id));
            $tmp_array = array();
            foreach ($this->getChildrenCategories($id) as $category) {
                array_push($tmp_array, $category->getId());             
            }
            $childIdsArray = array_merge($childIdsArray, $tmp_array);
            foreach ($this->getChildrenCategories($id) as $category){
                $this->retrieveAllChilds($category->getId(), $childIdsArray);
            }
        }
        else{
            return array_unique($childIdsArray);
        }

        return array_unique($childIdsArray);
}

but seems that there's something wrong in the stop or in the exit condition. the function retrieve correctly first 16 elements. anybody could help me?

如标题中所述,我正在尝试通过自定义函数执行此操作: \ n

  public function retrieveAllChilds($ id = null,$ childs = null){
 
 $ childIdsArray = is_null($ childs)?  array():$ childs; 
 $ category = is_null($ id)?  $ this-> getCurrentCategory():$ this-> getCategoryFromId($ id); 
 if(count($ this-> getChildrenCategories($ id))> 0){
 $ c = count($  this-> getChildrenCategories($ id)); 
 $ tmp_array = array(); 
 foreach($ this-> getChildrenCategories($ id)as $ category){
 array_push($ tmp_array,$ category-&gt  ;的getId());  
 $ \ child $ childIdsArray = array_merge($ childIdsArray,$ tmp_array); 
 foreach($ this-> getChildrenCategories($ id)as $ category){
 $ this-> retrieveAllChilds($ category->  getId(),$ childIdsArray); 
} 
} 
 else {
 return array_unique($ childIdsArray); 
} 
 
返回array_unique($ childIdsArray); 
} 
    
 
 

但似乎停止或退出条件有问题。 该函数正确检索前16个元素。 有人可以帮帮我吗?

    I think the class Mage_Catalog_Model_Category already includes the function you are searching. It is called getChildren:

    public function retrieveAllChilds($id = null, $childs = null) {
        $category = Mage::getModel('catalog/category')->load($id);
        return $category->getChildren();
    }
    

    The function getChildren returns children IDs comma-separated, getChildrenCategories returns an array of Mage_Catalog_Model_Category instances.

    If you want to get the children categories recursively, you can use:

    public function retrieveAllChilds($id = null, $childs = null) {
        $category = Mage::getModel('catalog/category')->load($id);
        return $category->getResource()->getChildren($category, true);
    }
