Laravel send variable to the view

Question

routes.php

    Route::post(\"/{user}/{char_name}\", array(
        \'as\' => \'char-profile-post\',
        \'uses\' => \'ProfileController@postDropDownL         


        

Answer 1

Laravel can absolutely send multiple variables to a view, and here's some code showing how I do it in a project of mine:

Route:

Route::get('play/{id}', array('before' => 'loggedin', 'uses' => 'GameController@confirmEntry'));

As you can see, in this route, I expect the variable id to be passed to my controller.

Controller:

public function confirmEntry($id){
    //stuff that doesn't matter
    $data = array('puzzle' => $puzzle,
                  'user'   => $user,
                  'wallet' => $wallet);
    return View::make('game.solver-confirm', $data);
}

In the above example, since I list $id as a parameter, and I have id in my route, $id will be set to whatever it was in the route. For instance, if I went to play/56, $id would be equal to 56.

View:

@foreach ($puzzle->tile as $tile)
    <li>a list gets made here</li>
@endforeach

You can see in the controller, I passed $puzzle (along with a few other variables) to the view, and then I call them just like you showed in my view.

Issues with yours:

The first issue I see is that you accept two variables from your route, and then overwrite them. That doesn't make much sense to me:

public function postDropDownList($user, $char_name) {
    $user = Auth::user();
    $char_name = Input::get('choose');
    //more stuff here
}

Why bother passing $user and $char_name only to overwrite them?

That makes me thing that the issue you're having is because your data is structured poorly. I'd suggest doing a var_dump or print_r to see how $char_name is actually being structured.

Answer 2

Ok, so here is how I partially resolved my issue.

routes.php

Route::group(array('prefix' => 'user'), function()
{       

    Route::post('/{user}/{char_name}/selectedok', array(
        'as' => 'char-profile-post',
        'uses' => 'ProfileController@postDropDownList'));   

    Route::get('/{user}/{char_name}/selectedok', array(
        'as' => 'char-profile-get',
        'uses' => 'ProfileController@getDropDownList'));                 

});

ProfileController.php

public function getDropDownList() {  

        return View::make('layout.profile');     

    }



public function postDropDownList($user, $char_name) {

    if (Auth::check())
    {   
        $user = Auth::user();
        $selected_char = Input::get('choose');
        $char_name = User::find($user->id)->characters()->where('char_name', '=', $selected_char)->first();


            return Redirect::route('char-profile-get', array($user->username, $char_name->char_dynasty, $char_name->char_name))
                    ->with('user', $user->username)
                    ->with('charname', $char_name->char_name)
                    ->with('dynastyname', $char_name->char_dynasty);



    }
}

Yes I know I redirect to 'char-profile-get' with 3 parametres, but I only need 2. It doesn't bother me. As you observe, I redirect with ->with. The only way I will print the data in the view is by doing this in the view:

 Your chosen character is {{ Session::get('charname') }} {{ Session::get('dynastyname')}}

If I don't overwrite the variables in postDropDownList($user, $char_name) my URL will literally look like this:

http://localhost/CaughtMiddle/tutorial/public/index.php/user/%7Buser%7D/%7Bchar_name%7D/selectedok

instead of this:

http://localhost/CaughtMiddle/tutorial/public/index.php/user/SerbanSpire/Spirescu/selectedok?Serban

So the verdict. The parametres in the functions will never receive any data. I don't even know how to describe them, the variables are inexistent, even if I redirect to the get route with the correct data. var_dump($user) or var_dump($char_name) doesn't print anything on the browser, dd($user) dd($char_name) also doesn't print anything nor does print_r().

Is my solution a viable one? By redirecting using ->with and storing the data in Session? Because this solution will drive me into using Session::get() alot! Stop me if I am wrong.
