我想做的是制作一个foreach循环来获取所有产品,并从那些我希望获得类别ID的产品中获取。这样我以后可以检查某些类别。
$order = new WC_Order( $order_id );
$items = $order->get_items();
foreach ( $items as $item ) {
$product_catagory_id .= $item['catagory_id']; //in between these brackets I need a value that gives me the catagory id.
}
//Some validation here if one of the catagorie_id's was found.
//I can build this. It's not part of the question
经过一番评论后,这就是我陷入困境的地方:
$order = new WC_Order( $order_id );
$items = $order->get_items();
foreach ( $items as $item ) {
$product_id = $item['product_id'];
var_dump($product_id);
$terms = get_the_term_list( $product_id, 'term_id' );
var_dump($terms);
}
这导致以下结果:
string(2) "79"
object(WP_Error)#9148 (2) {
["errors"]=>
array(1) {
["invalid_taxonomy"]=>
array(1) {
[0]=>
string(19) "Ongeldige taxonomie" //invalid taxonomy
}
}
["error_data"]=>
array(0) {
}
}
因此,产品ID读取完美,我可以使用,但类别未正确返回。
答案 0 :(得分:5)
尝试
$terms = get_the_terms ( $product_id, 'product_cat' );
foreach ( $terms as $term ) {
$cat_id = $term->id;
}
尝试var_dump($terms);
正确分析如何获取类别ID。
希望这有帮助。
