laravel7 权限菜单设置简易升缩

1:数据库填写数据,pid=0为*菜单,pid=对应的id为*菜单的子菜单

 2:laravel7 创建模型并链接对应的表名

<?php

namespace App\models;

use Illuminate\Database\Eloquent\Model;

class Node extends Model
{
    //
    protected $table='node';
}

 3:定义一个Base控制器,用于继承,里头书写递归方法:

<?php

namespace App\Http\Controllers\admin;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;

class Base extends Controller
{
    //递归处理层级
    public function sonlevel($data, $pid = 0)
    {
        $arr = [];
        foreach ($data as $key => $val) {
            if ($val['pid'] == $pid) {
                $val['son'] = $this->sonlevel($data, $val['id']);
                $arr[] = $val;
            }
        }
        return $arr;


    }


}

4:创建控制器:继承Base控制器,并将数据渲染至页面

<?php

namespace App\Http\Controllers\admin;

use App\Http\Controllers\Controller;
use App\models\Node;
use Illuminate\Http\Request;


class Index extends Base
{
    //展示Node模型数据列表
    public function index(){
     $data=Node::all();
//调用Base控制器的方法
    $datas=$this->sonlevel($data);
//将数据渲染至视图
    return view('admin.index.index',compact('datas'));
    }



}

5:视图进行双循环

<aside class="Hui-aside">
    <div class="menu_dropdown bk_2">
        @foreach($datas as $item)
        <dl id="menu-article">
            <dt><i class="Hui-iconfont">&#xe616;</i> {{$item['node_name']}}<i class="Hui-iconfont menu_dropdown-arrow">&#xe6d5;</i></dt>
            <dd>
                <ul>
                    @foreach($item['son'] as  $sons)
                    <li><a data-href="article-list.html" data-title="资讯管理" href="javascript:void(0)">{{$sons['node_name']}}</a></li>
                    @endforeach
                </ul>
            </dd>
        </dl>
        @endforeach

</aside>
