如何选择期权金额记录用户在laravel

Question

我正在尝试创建500个用户的选择选项

这是我的控制器

public function index()
{
$request = new IlluminateHttpRequest();

$employees = Employee::select('name','phone','email','id', DB::raw('2020 - year(day_of_birth) as age'));
$amount = $request->record; 
dd($amount);// output is null
if( $amount == '25') $employees= $employees->paginate(25);
else if($amount == '50') $employees= $employees->paginate(50);
else if($amount == '100') $employees= $employees->paginate(100);
else if($amount == '250') $employees= $employees->paginate(250);
else $employees= $employees->paginate(500);
return view('employees.index',['employees'=>$employees]);
}

这是index.blade.php

...
<div class="clearfix">
<form class="title_left form-inline row" method="get" action="{{route('search')}}">

...        
</form>
<div class="custom-select">
<select name="record" class="custom-select">
<option value="25" selected="selected">25</option>
<option value="50">50</option>
<option value="100">100</option>
<option value="250">250</option>
<option value="500">500</option>
</select>
</div>
</div>
...

当我加载路由索引时，它总是有500个用户。

Answer 1

当您的所有条件都失败，然后执行else部分时，就会发生这种情况。你设定了500；

else $employees= $employees->paginate(500);

获取选项值请使用此

$request->input('option_field_name](；
