Laravel:未定义的变量

我的代码有问题。

我想要显示登录但我有

的学生的记录

我的view.blade上的未定义变量

这是我的模型

class Attendance extends Eloquent {
  public function users()
  {
    return $this->belongsTo('User', 'id');
  }
}

这是我的控制器

public function viewstudentAttendance()
{
$students = Auth::user()->id;

    //load view and pass users  
    return View::make('student.view')
        ->with('attendances', $students);   
}

最后这是我的view.blade

@extends('layouts.master')

@section('head')
@parent
<title>View Attendance</title>
@stop

        {{ HTML::style('css/bootstrap.css'); }}

@section('content')



</ul>
    @if ($students->count())

<table class="table table-striped table-bordered">
    <thead>
        <tr>
    <th>ID</th>
    <th>First name</th>
    <th>Last name</th>




        </tr>
    </thead>

    <tbody>
        @foreach ($students as $students)
            <tr>
       <td>{{ $students->id }}</td> 
      <td>{{ $students->firstname }}</td>
      <td>{{ $students->lastname }}</td>    




          @endforeach

            </tr>
      {{ HTML::script('js/bootstrap.js'); }}

    </tbody>

</table>

@else
There are no attendance recorded yet
@endif
@stop

我认为问题在于我的观点或我如何声明变量?请帮忙? :(

答案 0 :(得分:0)

public function viewstudentAttendance() {
    //This code turns ID ONLY Check the website out for a code that retrieves data so you can loop it.
    $students = Auth::user() - > id;
    //Code that counts number of student
    $studentCount = XXX(Google It)
    //load view and pass users  
    return View::make('student.view') - > with('attendances', $students);
    //Return StudentCount too
}

在您的刀片模板中,使用:

@if ($studentCount > 10)

而不是

@if ($students->count())

你的学生正在归还身份证,你怎么能“数”

http://laravel.com/docs/4.2/eloquent

在你的刀片内你一直在做($学生)bla bla,只是为了让你知道它的出席情况

- &gt; with('attendances',$ students);

出勤率是您的刀片将看到的变量,$ student是您正在推动刀片出席的数据
