Laravel 节点列表

模型层:

//绑定数据表’
    protected $table = 'node';

    protected $guarded = [];


    //获取全部数据
    public function getAllList() {
        $data = self::get()->toArray();
        return $this->treeLevel($data);
    }

    //数组的合并，并加上html标识前缀
    public function treeLevel(array $data, int $pid = 0, string $html = '--', int $level = 0) {
        static $arr = [];
        foreach ($data as $val) {
            if ($pid == $val['pid']) {
                // 重复一个字符多少次
                $val['html'] = str_repeat($html, $level * 2);
                $val['level'] = $level + 1;
                $arr[] = $val;
                $this->treeLevel($data, $val['id'], $html, $val['level']);
            }
        }
        return $arr;
    }

 

 

控制器:

 //节点
    public function index(){
        $data =(new Node)->getAllList();
        return view('ten.node',['data'=> $data]);
    }

    //新增节点
    public function add(){
        //查找节点为0的
        $data = DB::table('node')->where('pid',0)->get();
        return view('ten.add',['data'=>$data]);
    }

    //添加处理
    public function dotenadd(Request $request){
        
        $data = $request->except('_token','id');    //获取所有数据
        $data['pid'] = $request['id'];      
        $res = DB::table('node')->insert($data);
        
        if($res){
            return redirect(route('ten_list'));
        }else{
            echo '添加失败';
        }
    }

路由:

Route::group(['prefix'=>'ten'],function(){

    Route::post('dotenadd','TenController@dotenadd')->name('dotenadd');  //添加处理
});
