我使用的插件包含以下代码：

    $download = array(
        \'post_title\'   => $title,
        \'post_content\' => \'\',
        \'post_status\'  => \'publish\',
        \'post_author\'  => get_current_user_id(),
        \'post_type\'    => \'dlm_download\'
    );

    $download_id = wp_insert_post( $download );

    if ( $download_id ) {

        // Meta
        update_post_meta( $download_id, \'_featured\', \'no\' );
        update_post_meta( $download_id, \'_members_only\', \'no\' );

我想创建自己的插件，以便在所有情况下将\\u members\\u only值设置为yes。到目前为止，我得到的代码是：

function dlmc_members_only_default( $check, $object_id, $meta_key, $meta_value, $prev_value )
{
    // Avoid infinite recursion:
    remove_filter( current_filter(), __FUNCTION__ ); 

    // Modify the meta value;
    $meta_value = "yes";

    // Update the modified value.
    update_post_meta( $object_id, $meta_key, $meta_value, $prev_value ); 

    // Return something else than null
    return true; 
}
add_filter( \'update_post_metadata\', \'dlmc_members_only_default\', 11, 5 );

不幸的是，这似乎让wordpress陷入了一个无限循环，尽管有一行人打算阻止它。有没有更好的方法来实现我的目标？谢谢

add_action("wp_insert_post", function( $post_ID ) {

    if ( ! $post_data = get_post( $post_ID ) ) return;

    // try to make this run only once needed ( from the question, the content is empty and cPT is dlm_download )
    if ( "dlm_download" == $post_data->post_type && ! $post_data->post_content ) {
        update_option( "dlm_download_members_only_yes", $post_data->ID );
    }

    return;

}, 10);

add_action("init", function() {
    if ( $pid = (int) get_option( "dlm_download_members_only_yes" ) ) {
        update_post_meta( $pid, "_members_only", "yes" );
        delete_option( "dlm_download_members_only_yes" );
    } return;
});
