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
}
}
}
}
