laravel8.5与layuiadmin整合(11)

53.添加新增，编辑，删除权限方法
/app/Http/Controllers/Admin/PermissionController.php
先增加添加方法

class PermissionController extends Controller
{
    // ................
        /**
     * 添加权限功能
     * @return \Illuminate\Contracts\View\Factory|\Illuminate\Contracts\View\View
     */
    public function create() {
        $permissions = $this->tree();
        return view('admin.permission.create',compact('permissions'));
    }

    /**
     * 处理新增加的权限功能
     * @param PermissionCreateRequest $request
     * @return \Illuminate\Http\RedirectResponse
     */
    public function store(Request $request) {
        $name = $request->input('name');
        $display_name = $request->input('display_name');
        $parent_id = $request->input('parent_id');
        $data = ['name' => $name,'display_name' => $display_name,
            'parent_id' => $parent_id];
        if(Permission::create($data)){
            return redirect()->to(route('admin.permission'))->with(['status' => '添加权限成功']);
        }else{
            return redirect()->to(route('admin.permission'))->withErrors(['status' => '系统错误']);
        }
    }
    
}

54.分别添加上面对应的模板
新增模板
/resources/views/admin/permission/create.blade.php

@extends('admin.base')

@section('content')
    <div class="layui-card">
        <div class="layui-card-header layuiadmin-card-header-auto">
            <h2>添加权限</h2>
        </div>
        <div class="layui-card-body">
            <form class="layui-form" action="{{route('admin.permission.store')}}" method="post">
                @include('admin.permission._from')
            </form>
        </div>
    </div>
@endsection


/resources/views/admin/permission/_from.blade.php

{{csrf_field()}}

<div class="layui-form-item">
    <label for="" class="layui-form-label">父级</label>
    <div class="layui-input-block">
        <select name="parent_id" lay-search>
            <option value="0">顶级权限</option>
            @forelse($permissions as $perm)
            <option value="{{$perm['id']}}" {{ isset($permission->id) && $perm['id'] == $permission->parent_id ? 'selected' : '' }} >{{$perm['display_name']}}</option>
                @if(isset($perm['_child']))
                    @foreach($perm['_child'] as $childs)
                    <option value="{{$childs['id']}}" {{ isset($permission->id) && $childs['id'] == $permission->parent_id ? 'selected' : '' }} >&nbsp;&nbsp;┗━━{{$childs['display_name']}}</option>
                                @if(isset($childs['_child']))
                    @foreach($childs['_child'] as $lastChilds)
                    <option value="{{$lastChilds['id']}}" {{ isset($permission->id) && $lastChilds['id'] == $permission->parent_id ? 'selected' : '' }} >&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;┗━━{{$lastChilds['display_name']}}</option>
                    @endforeach
                    @endif
                    @endforeach
                @endif
            @empty
            @endforelse
        </select>
    </div>
</div>


<div class="layui-form-item">
    <label for="" class="layui-form-label">显示名称</label>
    <div class="layui-input-block">
        <input type="text" name="display_name" value="{{$permission->display_name??old('display_name')}}" lay-verify="required" class="layui-input" placeholder="如：系统管理">
    </div>
</div>
<div class="layui-form-item">
    <label for="" class="layui-form-label">路由</label>
    <div class="layui-input-block">
        <input class="layui-input" type="text" name="name" value="{{$permission->name??old('name')}}" placeholder="如：admin.member" >
    </div>
</div>


<div class="layui-form-item">
    <div class="layui-input-block">
        <button type="submit" class="layui-btn" lay-submit="" >确 认</button>
        <a href="{{route('admin.permission')}}" class="layui-btn"  >返 回</a>
    </div>
</div>

至此，即权限可以添加了

55.添加编辑权限模板

/resources/views/admin/permission/edit.blade.php

@extends('admin.base')

@section('content')
    <div class="layui-card">
        <div class="layui-card-header layuiadmin-card-header-auto">
            <h2>更新权限</h2>
        </div>
        <div class="layui-card-body">
            <form class="layui-form" action="{{route('admin.permission.update',['id'=>$permission->id])}}" method="post">
                {{method_field('put')}}
                <input type="hidden" name="id" value="{{ $permission->id }}">
                @include('admin.permission._from')
            </form>
        </div>
    </div>
@endsection

56.方法中添加对应的方法
/app/Http/Controllers/Admin/PermissionController.php

//
    /**
     * 编辑权限
     * @param $id
     * @return \Illuminate\Contracts\View\Factory|\Illuminate\Contracts\View\View
     */
    public function edit($id) {
        $permission = Permission::findOrFail($id);
        $permissions = $this->tree();
        return view('admin.permission.edit',compact('permissions','permission'));
    }

    /**
     * 保存权限修改
     * @param Request $request
     * @param $id
     * @return \Illuminate\Http\RedirectResponse
     */
    public function update(Request $request, $id)
    {
        $permission = Permission::findOrFail($id);
        $data = [];
        $name = $request->get('name');
        $display_name = $request->get('display_name');
        $parent_id = $request->get('parent_id');
        $data['name'] = $name;
        $data['display_name'] = $display_name;
        $data['parent_id'] = $parent_id;
        if ($permission->update($data)){
            return redirect()->to(route('admin.permission'))->with(['status'=>'更新成功']);
        }
        return redirect()->to(route('admin.permission'))->withErrors('系统错误');
    }
    
    /**
     * 删除对应的权限
     * @param Request $request
     * @return \Illuminate\Http\JsonResponse
     */
    public function destroy(Request $request) {
        $ids = $request->get('ids');

        if (empty($ids)){
            return response()->json(['code'=>1,'msg'=>'请选择删除项']);
        }
        if (Permission::destroy($ids)){
            return response()->json(['code'=>0,'msg'=>'删除成功']);
        }
        return response()->json(['code'=>1,'msg'=>'删除失败']);
    }
