在设计权限库时遇到了对象和数组生成的问题,欢迎大家来讨论

    //首先获取所有菜单
    $data = DB::table("menu")->where('isDel', 0)->get();
    //遍历数据
    $list = [];
    foreach ($data as $key => $value) {
        $fatherId = $key['fatherId'];
            if ($value->fatherId == $fatherId) {
                if($value->id!==1) {
                    $value->children = [];
                }
                $list[] = $value;
            }
    }
    return $list;

父级代码如上,,继续研究 children 里面的对象怎么放进去 持续更新,到解决完….给那些像我一样努力的新人

实现后的代码如下, 给到和我一样的新人学习 , 不过想研究 怎么只读取一次数据库 然后 进行渲染,,,继续研究

    $data = DB::table("menu")->where('isDel', 0)->get();
    $list = [];
    foreach ($data as $key => $value) {
        $fatherId = $key['fatherId'];
        if ($value->fatherId == $fatherId) {
            if ($value->id !== 1) {
                $value->children = DB::table("menu")->where('fatherId', $value->id)->get();
            }
            $list[] = $value;
        }
    }
    return $list;

感觉你说的东西是 ORM 关联关系做简单很多

ORM方式

Controoler:

$data = Menu::where(['fatherId'=>0,'isDel'=>0]) ->select('id','title','href','fontFamily','icon','spread','isCheck') ->with(['children:fatherId,title,href,fontFamily,icon,spread']) ->get();

Model

public function children() { return $this->hasMany(Menu::class,'fatherId','id'); }
