如何使用 Codeigniter 4 和 Shield 权限构建 HTML 表格

Question

使用 Codeigniter 4.3.3、Shield 1.0.0-beta.5 和 MySQL

我确定我把这个复杂化了......我想使用 auth_permissions_users 表和 2 个左侧导航表 sidebar_modules 和 sidebar_modules_sub 构建一个 html 表。

默认情况下，Shield 喜欢使用存储在 auth_permissions_users 表中的 Group.Permission IE：admin.useredit、admin.useradd 等...我将使用传统的 controller.permission 方法，这就是其他表的原因。

对于桅杆部分，我可以正常工作，但似乎应该有更简单的方法......我在 helpers 文件夹中的 array_helper.php 中构建了一个函数。该函数将拆分 controller.permission，按控制器对它们进行分组，然后根据它找到的内容构建表。虽然我说它有效，但我有 2 个问题：

#1 - 我想要表格 IE 中的 5 行：|控制器 |创建 |阅读 |更新 |删除 |所以如果没有向用户提供权限，我必须填写任何空白。

#2 - 需要弄清楚如何以它们在表格中完全正确的方式对它们进行排序，这样我就可以添加一个 jQuery 元素来单击并根据需要更改用户的权限。它们并不总是以相同的顺序输入数据库表

来自 Shield 的数据使用 $user->getPermissions();

Array
(
    [0] => admin.read
    [1] => usergroups.read
    [2] => usergroups.create
    [3] => usergroups.update
    [4] => usergroups.delete
    [5] => users.read
    [6] => users.update
    [7] => users.create
    [8] => activitylogs.read
    [9] => authgroups.read
    [10] => authgroups.create
    [11] => authgroups.update
    [12] => authgroups.delete
)

我也写了另一个查询，但似乎与权限排序的结果相同

SELECT DISTINCT 
  SUBSTRING_INDEX(SUBSTRING_INDEX(`permission`,'.', 1),'.', -1) AS `controllers`,
  SUBSTRING_INDEX(SUBSTRING_INDEX(`permission`,'.', 2),'.', -1) AS `permissions`,
  `auth_permissions_users`.`permission`,
  `modules`.`slug` AS `modules`,
  `sub_modules`.`slug` AS `sub_modules`
FROM
  `auth_permissions_users`
  LEFT JOIN `sidebar_modules` AS `modules` ON (`modules`.`slug` = SUBSTRING_INDEX(`permission`,'.', 1))
  LEFT JOIN `sidebar_modules_sub` AS `sub_modules` ON (`sub_modules`.`slug` = SUBSTRING_INDEX(`permission`,'.', 1))

我在侧边栏表格中使用“slug”来识别控制器。在路由中，我将显示方法 userGroups 的 user_groups。和菜单语言文件中的 user_groups。输出如下所示：

array_helper.php

if (!function_exists('array_reorder_keys')) {
    
    /**
     * function array_reorder_keys
     * reorder the keys of an array in order of specified keynames; all other nodes not in $keynames will come after last $keyname, in normal array order

    function array_reorder_keys(&$array, $keynames){
        if(empty($array) || !is_array($array) || empty($keynames)) return;
        if(!is_array($keynames)) $keynames = explode(',',$keynames);
        if(!empty($keynames)) $keynames = array_reverse($keynames);
        foreach($keynames as $n){
            if(array_key_exists($n, $array)){
                $newarray = array($n=>$array[$n]); //copy the node before unsetting
                unset($array[$n]); //remove the node
                $array = $newarray + array_filter($array); //combine copy with filtered array
            }
        }
    }
}

这是表格现在的样子，请注意它们的顺序不正确。它应该与列标题正确对齐：

|控制器 |创建 |阅读 |更新 |删除 |
