Php 创建类别树
我的Php 创建类别树,php,wordpress,woocommerce,Php,Wordpress,Woocommerce,我的WoodPress（woocommerce）中包含了这些类别，我需要使用从WooCommerceAPI检索的数据构建一个这样的人 建立这样一个男人的有效方法是什么？我试图检查wordpress代码，但没有找到答案 这个API允许我检索所有产品类别 这是从请求中获得的对象： array(5) { [0] => object(stdClass)#77 (10) { ["id"] => int(15) ["name"] => string(13) "Unc

最后，我用递归函数计算出：
private function _categoriaOrder($level = 0) {
echo "<ul>";
for($i = 0; $i < count($this->_mycats[$level]); $i++) {
echo "<li style='list-style-type: none;'><label style=\"margin-bottom:0;\" for=\"woo_id_categoria_{$this->_mycats[$level][$i]['id']}\"><input value=\"{$this->_mycats[$level][$i]['id']}\" id=\"woo_id_categoria_{$this->_mycats[$level][$i]['id']}\" name=\"woo_id_categoria[]\" type=\"checkbox\"> <span>" . $this->_mycats[$level][$i]['id'] . " " . $this->_mycats[$level][$i]['name'] . "</span></label>";
if(array_key_exists($this->_mycats[$level][$i]['id'], $this->_mycats)) {
$this->_categoriaOrder($this->_mycats[$level][$i]['id']);
}
echo "</li>";
}
echo "</ul>";
}
public function getCategoriaTree(){
$categorie = $this->woo->getCategoria(); //here is the object with categories from woocommerce
foreach($categorie as $k => $category){
$this->_mycats[(int)$category->parent][] = array(
'id' => $category->id,
'name' => $category->name,
);
$categories_ordered[(int)$category->parent] = $category;
}
ob_start();
$this->_categoriaOrder();
$output = ob_get_contents();
ob_end_clean();
return $output;
}
私有函数\u分类顺序（$level=0）{
回声“”；
对于（$i=0；$i_mycats[$level]）；$i++）{
echo“- ”$this->\u mycats[$level][$i]['id']。”。$this->\u mycats[$level][$i]['name']。”；
如果（数组\密钥\存在（$this->\ mycats[$level][$i]['id']，$this->\ mycats））{
$this->_categoriaoorder（$this->_mycats[$level][$i]['id']）；
}
回声“
”；
}
回声“

}
公共函数getCategoriaTree（）{
$categorie=$this->woo->getCategoria（）；//这是woocommerce中包含类别的对象
foreach（$k=>$category分类）{
$this->_mycats[（int）$category->parent][]=数组(
'id'=>$category->id，
“名称”=>$category->name，
);
$categories\u ordered[（int）$category->parent]=$categories；
}
ob_start（）；

返回$output；
