我正在尝试创建所有这些if语句:
到目前为止,除“缺货”部分外,这两种语句均有效。知道如何调用和设置库存状态吗?
add_action( 'save_post', 'auto_add_product_category', 50, 3 );
function auto_add_product_category( $post_id, $post, $update ) {
if ( $post->post_type != 'product') return;
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE )
return $post_id;
if ( ! current_user_can( 'edit_product', $post_id ) )
return $post_id;
$term_id_A = 116; //category A
$term_id_B = 1459; //category B
$terms = get_the_terms( $post_id, 'product_cat' );
$term_ids = wp_list_pluck( $terms, 'term_id' );
if(in_array($term_id_A, $term_ids) && ($key = array_search($term_id_B, $term_ids)) !== false) {
unset($term_ids[$key]);
} elseif(!in_array($term_id_A, $term_ids) && !in_array($term_id_B, $term_ids)) {
$term_ids[] = $term_id_B;
}
wp_set_post_terms($post_id, $term_ids, 'product_cat');
}
答案 0 :(得分:1)
您需要使用以下内容替换代码的最后一部分:
if(in_array($term_id_A, $term_ids) && ($key = array_search($term_id_B, $term_ids)) !== false) {
//remove term A from the terms array:
unset($term_ids[$key]);
//set stock level to zero:
$out_of_stock_staus = 'outofstock';
// 1. Updating the stock quantity
update_post_meta($post_id, '_stock', 0);
// 2. Updating the stock quantity
update_post_meta( $post_id, '_stock_status', wc_clean( $out_of_stock_staus ) );
// 3. Updating post term relationship
wp_set_post_terms( $post_id, 'outofstock', 'product_visibility', true );
// And finally (optionally if needed)
wc_delete_product_transients( $post_id ); // Clear/refresh the variation cache
} elseif(!in_array($term_id_A, $term_ids) && !in_array($term_id_B, $term_ids)) {
$term_ids[] = $term_id_B;
}
