Passing data from controller to view in Laravel

问题

Hey guys 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.

I have a controller - ProfileController and inside that a function:

    public function showstudents()
     {
    $students = DB::table('student')->get();
    return View::make("user/regprofile")->with('students',$students);
     }

In my view I have this code

    <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)

回答1:

Can you give this a try,

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,

$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.

Inside Your controller create a method like:

function sleep()
{
        return view('welcome')->with('title','My App');
}

In Your route

Route::get('/sleep', 'TestController@sleep');

In Your View Welcome.blade.php. You can echo your variable like {{ $title }}

For An Array(multiple values) change,sleep method to :

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 }}.

The best and easy way to pass single or multiple variables to view from controller is to use compact() method.

For passing single variable to view,

return view("user/regprofile",compact('students'));

For passing multiple variable to view,

return view("user/regprofile",compact('students','teachers','others'));

And in view, you can easily loop through the variable,

@foreach($students as $student)
   {{$student}}
@endforeach

Try with this code:

return View::make('user/regprofile', array
    (
        'students' => $students
    )
);

Or if you want to pass more variables into view:

return View::make('user/regprofile', array
    (
        'students'    =>  $students,
        'variable_1'  =>  $variable_1,
        'variable_2'  =>  $variable_2
    )
);

回答5:

In Laravel 5.6:

$variable = model_name::find($id);
return view('view')->with ('variable',$variable);

回答6:

You can try this as well:

    public function showstudents(){
        $students = DB::table('student')->get();
        return view("user/regprofile", ['students'=>$students]);
    }

and use this variable in your view.blade file to get students name and other columns:

    {{$students['name']}}

回答7:

public function showstudents() {
     $students = DB::table('student')->get();
     return (View::make("user/regprofile", compact('student')));
}

回答8:

try with this code :

Controller:
-----------------------------
 $fromdate=date('Y-m-d',strtotime(Input::get('fromdate'))); 
        $todate=date('Y-m-d',strtotime(Input::get('todate'))); 

 $datas=array('fromdate'=>"From Date :".date('d-m-Y',strtotime($fromdate)), 'todate'=>"To 
        return view('inventoryreport/inventoryreportview', compact('datas'));

View Page : 
@foreach($datas as $student)
   {{$student}}

@endforeach
