您可以使用WP_Role 班

// get the the role object
$role_object = get_role( $role_name );

// add $cap capability to this role object
$role_object->add_cap( $capability_name );

// remove $cap capability from this role object
$role_object->remove_cap( $capability_name );

因此，为了解决您最初提出的关于如何让管理员在帖子内容中输入脚本和IFRAME标记的问题，您正在寻找“unfiltered\\u html”功能，这在多站点中仅授予超级管理员。

// get the the role object
$admin_role = get_role( \'administrator\' );
// grant the unfiltered_html capability
$admin_role->add_cap( \'unfiltered_html\', true );

也可以在函数中运行一次：

/* Roles & Capabilities */
add_role(\'professional\', \'Professional User\', array(
    \'read\' => true, // True allows that capability, False specifically removes it.
    \'edit_posts\' => true,
    \'delete_posts\' => true,
    //\'edit_published_posts\' => true,
    //\'publish_posts\' => true,
    //\'edit_files\' => true,
    \'upload_files\' => true //last in array needs no comma!
));
