首先：授予对项目的完全访问权限post type(Example).

在用户配置文件中添加允许的帖子id。

然后，如果不允许post id，请使用下面的筛选器限制访问。

function allow_user_to_edit_cpt_filter( $capauser, $capask, $param){

    global $wpdb;

    $allowed_posts_id_for_current_user = array( \'29\', \'30\' ); // you need to get these ids yourself
    $post = get_post( $param[2] );

    // If current post isn\'t allowed then delete edit and delete capabilities
    if( !in_array( $post->ID, $allowed_post_type_ids ) ){
        if( ( $param[0] == "edit_projects") || ( $param[0] == "delete_projects" ) ) { // Change to yours capabilities
            foreach( (array) $capask as $capasuppr) {
               if ( array_key_exists($capasuppr, $capauser) ) {
                  $capauser[$capasuppr] = 0;
               }
            }
        }
    }

    return $capauser;
}
add_filter(\'user_has_cap\', \'allow_user_to_edit_cpt_filter\', 100, 3 );
