我对Wordpress和PHP非常陌生，正在尝试为自定义帖子向批量编辑列表添加自定义字段。我关注了以下博文，但我的handle_bulk_actions 回调未启动：https://make.wordpress.org/core/2016/10/04/custom-bulk-actions/
这是我的代码：
/**
* Adds a new item into the Bulk Actions dropdown for custom products
list.
*/
function register_my_bulk_actions( $bulk_actions ) {
$bulk_actions[\'out_of_stock\'] = \'Mark as Out of Stock\';
$bulk_actions[\'in_stock\'] = \'Mark as In Stock\';
debug_to_console( \'Hello console\' );
return $bulk_actions;
}
add_filter( \'bulk_actions-edit-custom_product\', \'register_my_bulk_actions\' );
/**
* Handles the bulk action above.
* NOT FIRING!!
*/
function my_bulk_action_handler( $redirect_to, $action, $post_ids ) {
debug_to_console( \'Running handler\' );
if ( $action !== \'out_of_stock\' || $action !== \'in_stock\') {
return $redirect_to;
}
// let\'s remove query args first
$redirect_to = remove_query_arg( array( \'out_of_stock_done\', \'in_stock_done\' ), $redirect );
foreach ( $post_ids as $post_id ) {
if ($action === \'out_of_stock \') {
wp_update_post( array(
\'ID\' => $post_id,
\'in_stock\' => \'no\',
) );
$redirect_to = add_query_arg( \'out_of_stock_done\', count( $post_ids ), $redirect_to );
}
if ($action === \'in_stock \') {
wp_update_post( array(
\'ID\' => $post_id,
\'in_stock\' => \'yes\',
) );
$redirect_to = add_query_arg( \'in_stock_done\', count( $post_ids ), $redirect_to );
}
}
return $redirect_to;
}
add_filter( \'handle_bulk_actions-edit-custom_product\', \'my_bulk_action_handler\', 10, 3 );
/**
* Shows a notice in the admin once the bulk action is completed.
*/
function my_bulk_action_admin_notice() {
debug_to_console( \'Running notifier\' );
if ( ! empty( $_REQUEST[\'bulk_out_of_stock\'] ) ) {
$success_oos = intval( $_REQUEST[\'bulk_out_of_stock\'] );
printf(
\'<div id="message" class="updated fade">\' .
_n( \'%s product updated!\', \'%s products updated!\', $drafts_count, \'domain\' )
. \'</div>\',
$success_oos
);
}
}
add_action( \'admin_notices\', \'my_bulk_action_admin_notice\' );
谢谢！

嗨，首先修复你的状况
如果（$action！=“out\\u of\\u stock”| |$action！=“in\\u stock”）{
此条件将始终运行，因为您的操作与“out\\u of\\u stock”或“in\\u stock”相反。因此，我认为如果你将条件从或改为，它就会起作用。
然后找出屏幕id是否是您要查找的，然后修改过滤器：要了解您的屏幕id是什么，请将其添加到插件或主题函数中。php，请记住稍后将其删除：
add_filter( \'wc_product_has_unique_sku\', \'__return_false\' );
add_action(\'init\', \'test_function\');
function test_function(){
$value = get_current_screen();
echo \'<pre>\';
print_r($value);
echo \'</pre>\';
}
然后，当您获得正确的屏幕id（例如screen\\u id）时，请按如下方式修改过滤器：
add_filter( \'bulk_actions-SCREEN_ID\', \'register_my_bulk_actions\' );
