woocommerce построить дерево категорий

Question

У меня есть эти категории в моем wordpress (woocommerce), и мне нужно построить людей, подобных этому, используя данные, полученные из woocommerce api.

Какой эффективный способ построить такого мужчину? Я пытался проверить код WordPress без выяснения.

Этот API позволяет мне получать все категории продуктов.

https://woocommerce.github.io/woocommerce-rest-api-docs/#list-all-product-categories

это объект, полученный из запроса:

array(5) {
  [0] => object(stdClass)#77 (10) {
    ["id"] => int(15)
    ["name"] => string(13) "Uncategorized"
    ["slug"] => string(13) "uncategorized"
    ["parent"] => int(0)
    ["description"] => string(0) ""
    ["display"] => string(7) "default"

Answer 1

Наконец-то я разобрался, используя рекурсивную функцию:

    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\">&nbsp;<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;
    }

используйте функцию getCategoriaTree() для получения html.

Надеюсь, это кому-нибудь поможет, я потратил несколько часов на его получение.
