我在我的 WooCommerce 网站中创建了“新到货”产品类别部分。我希望分配给新类别的产品将隐藏或自动从“新到货”类别中删除，并且如果分配了一个或多个类别，则在其他类别中保持可见。
详细说明：
示例： 商品“红色T恤”被指定为“新品到货”和“促销”类别，那么15天后，该商品将被隐藏或从“新品到货部分”中删除，但在“新品到货部分”中仍然可见“销售”类别。
这是迄今为止我的代码：
// Add a custom action to schedule a job when a product is published
add_action('woocommerce_new_product', 'schedule_product_visibility_change', 10, 2);
function schedule_product_visibility_change($product_id, $product)
{
// Schedule the job to run after 15 days
wp_schedule_single_event(time() + 15 * DAY_IN_SECONDS, 'auto_hide_product_from_new_arrival', array($product_id));
}
// Hook to run when the scheduled job is triggered
add_action('auto_hide_product_from_new_arrival', 'auto_hide_product_from_new_arrival_callback');
function auto_hide_product_from_new_arrival_callback($product_id)
{
// Get product categories
$categories = wp_get_post_terms($product_id, 'product_cat', array('fields’ => ‘ids'));
// Check if the product is in the "New Arrival" category
if (in_array('new-arrival-category-id', $categories)) {
// Update product visibility
wp_set_object_terms($product_id, 'exclude-from-catalog', 'visibility', true);
}
}
// Restore product visibility if it’s removed from the “New Arrival” category before 15 days
add_action('woocommerce_remove_product_cat', 'restore_product_visibility_on_category_removal', 10, 2);
function restore_product_visibility_on_category_removal($product_id, $category)
{
// Get product categories
$categories = wp_get_post_terms($product_id, 'product_cat', array('fields' => 'ids'));
// Check if the product was in the "New Arrival" category
if ($category->term_id === 'new-arrival-category-id' && !in_array('new-arrival-category-id', $categories)) {
// Restore product visibility
wp_remove_object_terms($product_id, 'exclude-from-catalog', 'visibility');
}
}
但是我的代码不完整并且不起作用。任何帮助将不胜感激。
你让事情变得毫无意义，而且你的代码中有多个错误......你只需要在15天后安排“新品到货”类别取消分配，这样产品就不会再在“新品到货”类别中可见，但是将在分配给它的其他类别中保持可见。
尝试以下操作：
// Add a custom action to schedule a job when a product is published
add_action( 'woocommerce_new_product', 'schedule_unassign_product_category', 10, 2 );
function schedule_unassign_product_category( $product_id, $product ) {
// Schedule the job to run after 15 days
wp_schedule_single_event(time() + 15 * DAY_IN_SECONDS, 'unassign_new_arrival_product_category', array($product_id));
}
// Hook to run when the scheduled job is triggered
add_action( 'unassign_new_arrival_product_category', 'unassign_new_arrival_product_category_callback', 10, 1 );
function unassign_new_arrival_product_category_callback( $product_id )
{
$taxonomy = 'product_cat';
$terms = wp_get_post_terms($product_id, $taxonomy); // Get product categories
// Loop through assigned product categories
foreach( $terms as $key => $term ) {
// Check if the product is in the "New Arrival" category
if ( 'new-arrival' === $term->slug ) {
unset($terms[$key]); // Remove 'new-arrival' category from the array
if ( ! empty($terms) ) {
wp_set_object_terms($product_id, $terms, $taxonomy); // Update product assigned categories
}
break;
}
}
}
代码位于子主题的functions.php 文件中（或插件中）。应该可以。
还是不行
我也尝试过这段代码，请检查并建议该怎么做。
我还尝试按产品发布日期和产品修改日期获取产品，并将其分配给“最近”产品类别，但未收到所需的输出。
我只想将产品保留在发布日期后 15 天内 f
