我在网络中有几个站点。我不希望站点管理员管理网络插件之类的东西，但我希望他们能够编辑所有网络用户的个人资料，而不是使用他们站点上的个人资料。

在/wp-admin/network/users.php 文件如下：

if ( ! current_user_can( \'manage_network_users\' ) )
    wp_die( __( \'You do not have permission to access this page.\' ) );

如何授予站点管理员权限manage_network_users 没有把他们提升为超级管理员？

代码如下所示：

/**
 * Retrieve a list of super admins.
 *
 * @since 3.0.0
 *
 * @uses $super_admins Super admins global variable, if set.
 *
 * @return array List of super admin logins
 */
function get_super_admins() {
    global $super_admins;

    if ( isset($super_admins) )
        return $super_admins;
    else
        return get_site_option( \'site_admins\', array(\'admin\') );
}

/**
 * Determine if user is a site admin.
 *
 * @since 3.0.0
 *
 * @param int $user_id (Optional) The ID of a user. Defaults to the current user.
 * @return bool True if the user is a site admin.
 */
function is_super_admin( $user_id = false ) {
    if ( $user_id )
        $user = new WP_User( $user_id );
    else
        $user = wp_get_current_user();

    if ( empty( $user->id ) )
        return false;

    if ( is_multisite() ) {
        $super_admins = get_super_admins();
        if ( is_array( $super_admins ) && in_array( $user->user_login, $super_admins ) )
            return true;
    } else {
        if ( $user->has_cap(\'delete_users\') )
            return true;
    }

    return false;
}

    /**

     *

     */
    function has_cap( $cap ) {
#       fb($cap);
        if ( is_numeric( $cap ) ) {
            _deprecated_argument( __FUNCTION__, \'2.0\', __(\'Usage of user levels by plugins and themes is deprecated. Use roles and capabilities instead.\') );
            $cap = $this->translate_level_to_cap( $cap );
        }

        $args = array_slice( func_get_args(), 1 );
        $args = array_merge( array( $cap, $this->ID ), $args );
        $caps = call_user_func_array( \'map_meta_cap\', $args );

        // Multisite super admin has all caps by definition, Unless specifically denied.
        if ( is_multisite() && is_super_admin( $this->ID ) ) {
            if ( in_array(\'do_not_allow\', $caps) )
                return false;
            return true;
        }

        // Must have ALL requested caps
        $capabilities = apply_filters( \'user_has_cap\', $this->allcaps, $caps, $args );
        $capabilities[\'exist\'] = true; // Everyone is allowed to exist
        foreach ( (array) $caps as $cap ) {
            //echo "Checking cap $cap
";
            if ( empty( $capabilities[$cap] ) || !$capabilities[$cap] )
                return false;
        }

        return true;
    }

来自用户的代码。wp admin中的php显示编辑网络用户的第二个功能检查：

// Only allow super admins on multisite to edit every user.
if ( is_multisite() && ! current_user_can( \'manage_network_users\' ) && $user_id != $current_user->ID && ! apply_filters( \'enable_edit_any_user_configuration\', true ) )
    wp_die( __( \'You do not have permission to edit this user.\' ) );

function mc_admin_users_caps( $caps, $cap, $user_id, $args ){

    foreach( $caps as $key => $capability ){

        if( $capability != \'do_not_allow\' )
            continue;

        switch( $cap ) {
            case \'edit_user\':
            case \'edit_users\':
                $caps[$key] = \'edit_users\';
                break;
            case \'delete_user\':
            case \'delete_users\':
                $caps[$key] = \'delete_users\';
                break;
            case \'create_users\':
                $caps[$key] = $cap;
                break;
        }
    }

    return $caps;
}
add_filter( \'map_meta_cap\', \'mc_admin_users_caps\', 1, 4 );
remove_all_filters( \'enable_edit_any_user_configuration\' );
add_filter( \'enable_edit_any_user_configuration\', \'__return_true\');

/*

add_action(\'pre_user_query\',\'isa_pre_user_query\');
function isa_pre_user_query($user_search) {
  $user = wp_get_current_user();
  if ($user->ID!=1) { // Is not administrator, remove administrator
    global $wpdb;
    $user_search->query_where = str_replace(\'WHERE 1=1\',
      "WHERE 1=1 AND {$wpdb->users}.ID<>1",$user_search->query_where);
