我用这些功能制作了一个自定义的post-type evement。在这里，我只是把能力参数。

\'capability_type\' => \'evenement\',
\'map_meta_cap\' => true,
\'capabilities\' => array(
    // meta caps (don\'t assign these to roles)
    \'edit_post\' => \'edit_evenement\',
    \'read_post\' => \'read_evenement\',
    \'delete_post\' => \'delete_evenement\',

    // primitive/meta caps
    \'create_posts\' => \'create_evenements\',

    // primitive caps used outside of map_meta_cap()
    \'edit_posts\'  => \'edit_evenements\',
    \'edit_others_posts\'  => \'manage_evenements\',
    \'publish_posts\' => \'publish_evenements\',
    \'read_private_posts\' => \'read\',

    // primitive caps used inside of map_meta_cap()
    \'read\' => \'read\',
    \'delete_posts\' => \'delete_evenements\',
    \'delete_private_posts\' => \'delete_private_evenements\',
    \'delete_published_posts\' => \'delete_published_evenements\',
    \'delete_others_posts\' => \'manage_evenements\',
    \'edit_private_posts\' => \'edit_evenements\',
    \'edit_published_posts\' => \'edit_evenements\'
    )

对于我使用的add\\u cap函数

// CPT event
function manage_event_capabilities() {
    $admin = get_role(\'administrator\');
    $institution = get_role(\'institution\');
    $institutionspecial = new WP_User(105);
    $caps = array(
        \'create_evenements\',
        \'delete_evenements\',
        \'delete_private_evenements\',
        \'delete_published_evenements\',
        \'edit_evenements\',
        \'manage_evenements\',
        \'publish_evenements\'
    );

    foreach($caps as $cap) {
        $admin->add_cap($cap);
    }

    // $admin->remove_cap(\'exec_php\');

    // basique
    $institution->add_cap(\'upload_files\');

    // event
    $institution->add_cap(\'create_evenements\');
    $institution->add_cap(\'edit_evenements\');
    $institution->remove_cap(\'publish_evenements\');
    $institution->add_cap(\'delete_evenements\');
    $institution->add_cap(\'special_institution\');


}

一切都很完美，除了一个想法。管理员无法列出具有此自定义角色的所有用户institution. 如果我想更改作者，我只需要当前作者（具有机构角色）或所有normal 网站作者。

你能帮帮我吗？谢谢
