laravel从控制器传递数据库数组到视图

Question

hello people here is my code below for controller

$siteinformation = DB::table('siteinformation')->where('Site',$myarr[0]['site'])->select()->get();

print_R($siteinformation); will display

Array ( [0] => stdClass Object ( [Site] => site1 [Nickname] => friend [ProgramID] => 1 [CreateDateTime] => 2014-06-03 18:05:39 ) )

I am trying to pass it to view

return Redirect::to('sbs_site')->with('siteinformation',$siteinformation);

In my view i have...

@if(Session::has('siteinformation'))
@foreach ($siteinformation as $key => $value) 

{{ $value->Nickname }}

@endforeach
    @endif

Iam gettng an error Undefined variable: siteinformation

my route file contains... Route::post('sbs_site', array('uses' => 'myController@sys_config'));

what could be the problem??

Answer 1

I think you don't need to redirect; probably you are doing it wrong, instead you should pass the data to the view directly using something like this:

$siteinformation = DB::table('siteinformation')
                     ->where('Site',$myarr[0]['site'])
                     ->get();
// View Name: "sbs_site.blade.php"
return View::make('sbs_site')->with('siteinformation', $siteinformation);

Then in the view:

@foreach ($siteinformation as $value) 

    {{ $value->Site }}
    {{ $value->Nickname }}

@endforeach

But if your really need to use a redirect then you may do it like this:

// Route Is: "sbs_site"
return Redirect::to('sbs_site')->with('siteinformation', $siteinformation);

Then in your view:

@if(Session::has('siteinformation'))

    @foreach (Session::get('siteinformation') as $value) 

    {{ $value->Site }}
    {{ $value->Nickname}}

    @endforeach

@endif

This worked for me...

in view

     @if(Session::has('siteinformation'))

     @foreach (Session::get('siteinformation')as $key => $value) 

     {{ $value->Nickname}}

      @endforeach

     @endif

In controller

    return Redirect::to('sbs_site')->with('siteinformation',$siteinformation);

Answer 3

Your view file is not getting session set if(Session::has('siteinformation')), because you did not set session in your controller. You set in your controller 'siteinformation' as a normal variable. If you want to set session, instead of this.

Redirect::to('sbs_site')->with('siteinformation',$urserializedobj);

Do this

Session::put('siteinformation',$urserializedobj);
Redirect::to('sbs_site');

OR

Simply don't check session in your view instead of this

if(Session::has('siteinformation'))

Just do this

if (!empty($siteinformation)) :

I don't know why u are redirecting to pass it to the view

return View::make('yourview',array('siteinformation'=>$siteinformation));

This will do the trick if you can make the view directly from the controller BUT if u need to redirect than i suppose you can serialize your array or change it to json first because the with function passes the data as flash so only strings

$urserializedobj = $siteinformation.toJson();//if this doesn't work try serealizing
return Redirect::to('sbs_site')->with('siteinformation',$urserializedobj );

now in your view you can do this

@if(Session::has('siteinformation'))
 $siteInformation = json_decode(Session::get('siteinformation'));
 @foreach ($siteinformation as $key => $value) 

 {{ $value->Nickname }}

 @endforeach
@endif
