大家好，我用这个代码
add_action( 'woocommerce_before_shop_loop_item_title', 'wk_out_of_stock_variations_loop' );
function wk_out_of_stock_variations_loop(){
global $product;
if ( $product->product_type == 'variable' ) { // if variation product is out of stock
$available = $product->get_available_variations();
if ( $available )foreach ( $available as $instockvar ) {
if ( isset($instockvar['attributes']['attribute_pa_megethos'] ) ) {
if ( ( $instockvar['attributes']['attribute_pa_megethos'] == $_GET['filter_megethos'] ) && (!$instockvar['max_qty']>0) ) {
global $product;
$id = $product->get_id();
echo "<style>.post-$id{display: none}</style>";
}
}
}
}
if ( !$product->is_in_stock() ) { // if single product is out of stock
global $product;
$id = $product->get_id();
echo "<style>.post-$id{display: none}</style>";
}
}
这个代码运行良好，但隐藏了产品，但它们的位置仍在页面上，但我不想显示不存在的产品并替换那些现有的产品
您应该从Wooccommerce->设置->库存->quot；从目录中隐藏缺货项目"；
您可以使用此代码。在修改后的代码中，我添加了一个额外的步骤，在将缺货产品显示在滑块或网格循环中之前，将其从$related_products数组中排除。
