Passing data from controller to view in Laravel
提问by VP1234
I am new to laravel and I have been trying to store all records of table 'student' to a variable and then pass that variable to a view so that I can display them.
我是 laravel 的新手，我一直在尝试将表 'student' 的所有记录存储到一个变量中，然后将该变量传递给一个视图，以便我可以显示它们。
I have a controller - ProfileController and inside that a function:
我有一个控制器 - ProfileController 里面有一个函数：
public function showstudents()
{
$students = DB::table('student')->get();
return View::make("user/regprofile")->with('students',$students);
}
In my view I have this code
在我看来，我有这个代码
<html>
<head></head>
<body> Hi {{Auth::user()->fullname}}
@foreach ($students as $student)
{{$student->name}}
@endforeach
@stop
</body>
</html>
I am receiving this error : Undefined variable: students (View:regprofile.blade.php)
我收到此错误：未定义变量：学生（查看：regprofile.blade.php）

Can you give this a try,
你可以试试这个吗
return View::make("user/regprofile", compact('students')); OR
return View::make("user/regprofile")->with(array('students'=>$students));
While, you can set multiple variables something like this,
虽然，您可以像这样设置多个变量，
$instructors="";
$instituitions="";
$compactData=array('students', 'instructors', 'instituitions');
$data=array('students'=>$students, 'instructors'=>$instructors, 'instituitions'=>$instituitions);
return View::make("user/regprofile", compact($compactData));
return View::make("user/regprofile")->with($data);

For Passing a single variable to view.
用于传递单个变量以查看。
Inside Your controller create a method like:
在您的控制器内部创建一个方法，如：
function sleep()
{
return view('welcome')->with('title','My App');
}
In Your route
在你的路线
Route::get('/sleep', 'TestController@sleep');
In Your View Welcome.blade.php. You can echo your variable like {{ $title }}
在您看来Welcome.blade.php。您可以像这样回显您的变量{{ $title }}
For An Array(multiple values) change,sleep method to :
对于数组（多个值）更改，睡眠方法为：
function sleep()
{
$data = array(
'title'=>'My App',
'Description'=>'This is New Application',
'author'=>'foo'
);
return view('welcome')->with($data);
}
You can access you variable like {{ $author }}.
您可以像{{ $author }}.

The best and easy wayto pass single or multiple variables to view from controller is to use compact()method.
传递单个或多个变量以从控制器查看的最佳且简单的方法是使用compact()方法。
For passing single variable to view,
为了将单个变量传递给 view，
return view("user/regprofile",compact('students'));
For passing multiple variable to view,
为了将多个变量传递给 view，
return view("user/regprofile",compact('students','teachers','others'));
And in view, you can easily loop through the variable,
在视图中，您可以轻松地遍历变量，
@foreach($students as $student)
{{$student}}
@endforeach

You can try this as well:
你也可以试试这个：
public function showstudents(){
$students = DB::table('student')->get();
return view("user/regprofile", ['students'=>$students]);
}
Also, use this variable in your view.bladefile to get students name and other columns:
此外，在您的view.blade文件中使用此变量来获取学生姓名和其他列：
{{$students['name']}}

In Laravel 5.6:
在 Laravel 5.6 中：
$variable = model_name::find($id);
return view('view')->with ('variable',$variable);
回答by Vanndy
Try with this code:
尝试使用此代码：
return View::make('user/regprofile', array
(
'students' => $students
)
);
Or if you want to pass more variables into view:
或者，如果您想将更多变量传递到视图中：
return View::make('user/regprofile', array
(
'students' => $students,
'variable_1' => $variable_1,
'variable_2' => $variable_2
)
);
