magento-在给定类别ID的情况下检索所有子类别 [英] magento - retrieve all children categories given a category id
本文介绍了magento-在给定类别ID的情况下检索所有子类别的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
如标题中所述,我正在尝试通过我的自定义函数执行此操作:
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($childIdsArray);
}
但是在停止或退出条件下似乎出了点问题.该函数正确检索前16个元素.有人可以帮助我吗?
but seems that there's something wrong in the stop or in the exit condition. the function retrieve correctly first 16 elements. anybody could help me?
推荐答案
我认为该类 getChildren
:
I think the class Mage_Catalog_Model_Category
already includes the function you are searching. It is called getChildren
:
public function retrieveAllChilds($id = null, $childs = null) {
$category = Mage::getModel('catalog/category')->load($id);
return $category->getChildren();
}
函数 getChildren
返回以逗号分隔的子ID, getChildrenCategories
返回Mage_Catalog_Model_Category
实例的数组.
如果要递归获取子类别,则可以使用:
If you want to get the children categories recursively, you can use:
public function retrieveAllChilds($id = null, $childs = null) {
$category = Mage::getModel('catalog/category')->load($id);
return $category->getResource()->getChildren($category, true);
}
