当产品在 WooCommerce 中“有货”时,product_visibility 分类是否设置为 false?

问题描述

根据 Hide WooCommerce variable product from catalog if all variations are out of stock 答案代码,我在检查所有变量产品的库存数量都小于 0 后,已使该变量产品脱销:

我的代码尝试:

{shops.map((shop,index) => {
    return (
      <Link to={`/barbershop${index}`} key={shop.id}>
        <ShopList
          shop={shop.shopName}
          address={shop.address}
          operation={shop.operatingHour}
          click={() => this.barberShopHandler(index)}
        ></ShopList>
      </Link>
    );
  })}

在上面的代码中,我将 function is_wc_variable_product_in_stock( $product_id ){ global $wpdb; $count = $wpdb->get_var( $wpdb->prepare( " SELECT COUNT(ID) FROM {$wpdb->posts} p INNER JOIN {$wpdb->postMeta} pm ON p.ID = pm.post_id WHERE p.post_type = 'product_variation' AND p.post_status = 'publish' AND p.post_parent = %d AND pm.Meta_key = '_stock' AND pm.Meta_value != '0' ",$product_id ) ); return $count > 0 ? true : false; } /* Set product out of stock if all it's variations are out of stock*/ function hide_out_of_stock_product() { global $product; $product_id = $product->get_id(); $is_prod_in_stock = is_wc_variable_product_in_stock( $product_id ); if ( ! $is_prod_in_stock && $product->get_type() === 'variable' ) { $out_of_stock_staus = 'outofstock'; // Updating the product status update_post_Meta( $product_id,'_stock_status',wc_clean( $out_of_stock_staus ) ); // Updating post term relationship wp_set_post_terms( $product_id,'outofstock','product_visibility',true ); } } add_action( 'woocommerce_after_shop_loop_item','hide_out_of_stock_product',9 ); 产品的 product_visiblity 设置为 true。现在我的问题是,当产品从仪表板 outofstock 制作时,product_visiblity 是否会被设置为 false?

希望我的问题很清楚。如果逻辑有缺陷,也请纠正我。

解决方法

不确定您使用的是正确的钩子...

当产品有货时,WooCommerce 会从后期关系中删除“product_visibility”分类法的缺货术语(术语 ID),并将 _stock_status 元键的后期元数据值设置为“instock”。>

要删除词后关系,您当然要使用 wp_remove_object_terms() 函数。

因此,您需要对第二个函数进行一些更改,以便在其任何变体有库存时使可变产品有库存(未经测试)

add_action( 'woocommerce_after_shop_loop_item','show_hide_variable_product_based_on_stock',9 );
function show_hide_variable_product_based_on_stock() {
    global $product;
    
    $product_id       = $product->get_id();
    $is_prod_in_stock = is_wc_variable_product_in_stock( $product->get_id() );
    $current_status   = get_post_meta( $product_id,'_stock_status',true );
    $status_to_set    = '';
    
    if ( $product->is_type('variable') ) {
        $status_to_set    = ''; 
        if ( ! $is_prod_in_stock && $current_status === 'instock' ) {
            $status_to_set = 'outofstock';
        } elseif ( $is_prod_in_stock && $current_status === 'outofstock' ) {
            $status_to_set = 'instock';
        } else {
            $status_to_set = '';
        }
        if ( ! empty($status_to_set) ) {
            // Updating the product status (meta data)
            update_post_meta( $product_id,$status_to_set ); 
            
            // Add or Remove "outofstock" post term relationship for "product_visibility" taxonomy
            if( $status_to_set === 'outofstock' ) {
                wp_set_post_terms( $product_id,'outofstock','product_visibility',true ); // Add
            } else {
                wp_remove_object_terms( $product_id,'product_visibility' ); // Remove
            }
        } 
    }
}
