Pluck with Where condition
提问by siddiq
I can take the list using
我可以使用列表
$specialities = Speciality::pluck('name','id')
Why isn't the following code working? What could be an alternative?
I am returning this array by ajax to form a select box. So I thought pluck(list in laravel 4+) would be the right choice.
为什么下面的代码不起作用？什么是替代方案？我通过ajax返回这个数组以形成一个选择框。所以我认为pluck（在 laravel 4+ 中列出）将是正确的选择。
$specialities = Speciality::pluck('name','id')->where('role_id',$request->roleid);

I found the mistake. I should use pluck with where condition like below.
我发现了错误。我应该在如下条件下使用 pluck。
$specialities = Speciality::where('role_id',$request->roleid)->pluck('name','id');
Pluck won't filter anything, but it gives only what needed. So filtering has to be done before that.
Pluck 不会过滤任何东西，但它只提供需要的东西。所以在此之前必须进行过滤。
