Unable to render views with variables [stumped]

daevski · 2013-01-01 16:39:08

(Answered below, thanks to anggietp :: http://forums.laravel.io/viewtopic.php?pid=23383#p23383 )

I've confirmed with the help of a StackOverflow user that my code is correct, but something in my environment is not correct. (stackoverflow com /questions/14107615/laravel-unable-to-render-variables)

I'm not sure where to begin puzzle solving, but maybe a kind developer or savvy user can help?
If I take out {{ $title }}, I get no error... but then I'm also not using variables :-\ Thanks in advance!!

The variable being passed is 'title'.

<?php 

class Add_Controller extends Base_Controller {
    public $restful = true;

    public function get_recipe(){
        return View::make('add.recipe', array('title' => 'Add A Recipe'));
        // I've also tried with() and others.
    }
}

The layout:

<!DOCTYPE HTML>
<html lang="en-US">
<head>
    <meta charset="UTF-8">
    <title>{{ $title }}</title>
    <link rel="stylesheet" href="{{ URL::to('css/style.css') }}">
    <link href='http://fonts.googleapis.com/css?family=Libre+Baskerville|Domine|Donegal+One' rel='stylesheet' type='text/css'>
    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
    <script src="{{ URL::to('js/functions.js') }}"></script>
</head>
<body>
    @yield('content')
</body>
</html>

recipe page:

@layout('layouts.default')
@section('content')
    <div id="wrapper">
        <header><div id="icon"></div></header>
        <div id="create">

                        </select>
                    </div>

                    </div>

Hi Daevski,

Have you tried doing it this way:
-------------------------------------------------------
public function get_recipe(){
$data = array('title' => 'Add A Recipe');
return View::make('add.recipe', $data);

}
-------------------------------------------------------

This works fine for me so I hope it helps you as well. If this doesn't work perhaps your routes file is incorrect? May be worth posting that as well :-)
Good luck,
Lew

I've just tried this, but it didn't help.
Note that if I remove {{$title}} it renders fine, so it's not a route issue, but my route is simply:

Route::get('/add/recipe', function()
{
	return View::make('add.recipe');
});

I don't know if it's related, but I took out the line under it:

<link rel="stylesheet" href="{{ URL::to('css/style.css') }}">

And tried to use an Asset instead:

	<title>Plain Title</title>
	<?php echo Asset::styles(); ?>

after adding this to base controller:

<?php

class Base_Controller extends Controller {

	public function __construct()
	{
	    //Assets
	    // Asset::add('jquery', 'js/jquery-1.7.2.min.js');
	    Asset::add('style', 'css/style.css');
	    parent::__construct();
	}

	/**
	 * Catch-all method for requests that can't be matched.
	 *
	 * @param  string    $method
	 * @param  array     $parameters
	 * @return Response
	 */
	public function __call($method, $parameters)
	{
		return Response::error('404');
	}

}

But the Asset code seems to do absolutely nothing (page source):

<!DOCTYPE HTML>
<html lang="en-US">
<head>
	<meta charset="UTF-8">
	<title>Plain Title</title>
	
</head>
<body>
		<div id="wrapper">
		<header><div id="icon"></div></header>
... 
...

It just seems to leave whitespace in the page source! :-\

You mentioned before, you access it from controller ...
That's wont work, and definitely route problem.

Why you make route to return View? You said you had a controller right?

 public function get_recipe(){
        return View::make('add.recipe', array('title' => 'Add A Recipe'));
        // I've also tried with() and others.
    }

So you should just do this (if you still wanna using route):

Route::get('add/recipe','add@recipe');

// or just register it because your controller is straightforward (same as route)
Route::controller('add');

Hi again,
I'm pretty sure the parent construct needs to be above the assets so hopefully that should help you:

public function __construct()
{
parent::__construct();
//Assets
// Asset::add('jquery', 'js/jquery-1.7.2.min.js');
Asset::add('style', 'css/style.css');
}

With your other problem I agree with that as well. If you link to your controller from your route and call the view from there (passing in your variables) you shouldn't have a problem.
Hope this works for you.

View::make('add.recipe', array('title' => 'Add A Recipe'));

Your code will pass $title to add.recipe. It does not pass $title to your layout. For this you either need to add another section to your view for the title, and yield that in your layout, or you could use View::share(string $key, mixed $value) to make $title available to all views.

Controller

     public function get_recipe(){
        Section::inject('title','Add A Recipe');
        return View::make('add.recipe');
    }

the layout

<!DOCTYPE HTML>
<html lang="en-US">
<head>
    <meta charset="UTF-8">
    <title>@yield('title')</title>
    <link rel="stylesheet" href="{{ URL::to('css/style.css') }}">
    <link href='http://fonts.googleapis.com/css?family=Libre+Baskerville|Domine|Donegal+One' rel='stylesheet' type='text/css'>
    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
    <script src="{{ URL::to('js/functions.js') }}"></script>
</head>
<body>
    @yield('content')
</body>
</html>

But why he succeeded? I also tried that and it worked. Variable title will be available in base layout, even we just call view make add.recipe...(using blade)
