我是laravel的新手,我试图从 here
清除问题我有以下控制器:
foreach($users as $user){
$message[] = Model::where('id',$user->id)->get();
}
$data['tests'] = $message;
return View::make('user.index', $data);
我的观点是:
@foreach($tests['message'] as $test)
id : {{$test->id}}
@endforeach
给了我Undefined index: message
我已将$data
转储到控制器中。我的数组如下所示。我将var_dump放在return语句之前的控制器中。我的var_dump($data)
正在显示:
array(1) {
["tests"] => array(2) {
[0] => object(Illuminate\ Database\ Eloquent\ Collection) #515 (1) { ["items":protected]= > array(2) {
[0] => ["attributes": protected] => array(14) {
["id"] => string(3) "12"....
}
}
[1] => object(Illuminate\ Database\ Eloquent\ Collection) #515 (1) { ["items":protected]= > array(2) {
[0] => ["attributes": protected] => array(14) {
["id"] => string(3) "12"....
}
}
}
我做错了什么。请帮帮我

<filter level="TraceEventType.Error" />
获取返回数组,如果要返回一个元素,请使用find()或first()。

您的$tests['message']
应为$tests
,因为您尚未在控制器中定义消息。
$message = array();
foreach($users as $user){
$message[] = Model::where('id',$user->id)->get();
}
$data['tests'] = $message;
return View::make('user.index', $data);
查看
@foreach($tests as $test)
id : {{$test->id}}
@endforeach

试试这个:
$users = App\User::all()
foreach($users as $user){
$message[] = Model::where('id',$user->id)->get();
}
$data['tests'] = $message;
return view( 'user.index', compact('data') );
在views / user.index.blade.php
中@foreach($data['tests'] as $test)
id : {{$test->id}}
@endforeach
