让 Woocommerce 使用产品标题中的关键字自动分配产品类别

如何解决让 Woocommerce 使用产品标题中的关键字自动分配产品类别

首先让我说清楚，我几乎没有任何编码经验，所以这里是。

我正在尝试为 Woocommerce 创建自定义 PHP 代码，目的是通过匹配可在产品标题中找到的一组关键字字符串来自动将产品分配到产品类别。我希望在导入、更新、更改或保存产品时执行此操作。

我找到了其他方法来实现这一点，但是我还没有找到简单地添加 object_terms 的方法。 这是我从其他代码创建的代码，我已经用于其他目的，我尝试编辑代码以满足我的要求。这是我目前编译的内容。

    add_action( 'woocommerce_product_quick_edit_save','get_cat_from_title',150,1 );
    // On admin single product creation/update
    add_action( 'woocommerce_process_product_meta',100,1);
    // On admin single product variation creation/update
    add_action( 'woocommerce_save_product_variation',1);
    add_action( 'save_post_product',1);
    add_action( 'save_product_category',1);
  // Update below //  function get_cat_from_title($title,$defaultcat) {
  // function get_cat_from_title($title) {
    function get_cat_from_title( $product_id) { 
        
    // get an instance of the WC_Product Object
        if (is_object($product_id)){
            $product  = $product_id;
            $product_id=$product->get_id();
        }else{
            $product  = wc_get_product( $product_id );
        }
                    
    // keyword in title - 'test1'
                if (strpos($title,'test1') !== false){
                    // category for found keyword 'test1'
                    $cat = "test1";
                    // category for found keyword 'test2'
    } elseif(strpos($title,"test2") !== false);{      
                $cat = "test2";
    
            switch ($cat) {
            // assign category test1
            case 'test1':
                    wp_add_object_terms ( $product_id,'test1','product_cat' );
                    break;  
            // assign category test2
            case 'test2':
                    wp_add_object_terms ( $product_id,'test2','product_cat' );
                break;
            default:
                # code...
                break;
            }
                }
    }

不幸的是，该代码对我不起作用，并在我的 debug.log 中引发了以下错误。

管理员通常会因为我没有清楚或正确地写出我的问题而责备我，我不是开发人员，我不理解所有的术语，但我真的希望我已经正确地发布了这个并足够清楚地解释了我的目标！也许有人可以告诉我我哪里出错了，以及如何通过一些编辑使这段代码工作。我乐于接受评论并始终愿意学习。谢谢:)
