I use laravel 5.2 and tried to display a carousel only in index page but doesn't work.
I chose that the codes are not "spreaded" on the index page, they are stored in: public/carousel/carousel.php, too(not ...blade.php).
route.php:
Route::get('/', 'HomeController#index')
HomeController.php:
{
$cats = Category::all();
$carousel = public_path('carousel/carousel.php');
//$carousel = storage_path('public/carousel/carousel.php');
return view('layouts.app', compact('cats', 'carousel'));
}
layouts/app.blade.php:
{{-- #include('carousel/carousel');--}}
#if($carousel)
{{ $carousel }}
#endif
#yield('content')
Finally it displays only: C:\wamp\www\app_name\public\carousel/carousel.php.
Can you help me or point to another better way?
In your controller, you are passing to the view a variable called $carousel, which is the path to your file, as you defined here:
$carousel = public_path('carousel/carousel.php');
This is the reason why it only displays the string. You need to get the actual content of the file:
$carousel = file_get_content(public_path('carousel/carousel.php'));
A better and more laravel-ish way to do it would be to rename the file to carousel.blade.php, store it into the resources/views folder and simply include it from your main blade file (without the need of doing anything in the controller):
#include('carousel')
If you need to display the carousel on certain pages only, you can simply pass a variable $carousel = true on the pages that needs to display it:
$carousel = true;
return view('layouts.app',compact('carousel'));
And in your blade view, include the carousel file only when this variables is present and is true:
#includeWhen(isset($carousel) && $carousel, 'carousel')

This is probably something simple, but it's doing my head in.
So, my layout blade template has this:
#include('layouts.partials.sidebar')
{{ $slot }}
#include('layouts.partials.footer')
#include('layouts.partials.scripts')
I create a view which loads a template. This I assume gets parsed in $slot.
return view('request', [
'boo' => 'Hoo'
]);
No problems, the page loads and the variable 'boo' is accessible as {{ $boo }} in the 'requests' template.
But my question is, how can I pass the 'boo' variable to an included file in the layout file? In this case the following:
#include('layouts.partials.scripts')
So, in 'layouts.partials.scripts' how can I access {{ $boo }}? At the moment I just get an undefined index error.
Thank you very much for the help.
#include('layouts.partials.scripts', ['boo' => 'Hoo'])

If you have a partial like a nav, header, or sidebar, part of the master layout from which you are composing other views. It requires data that doesn't change from one view to another, like navigation links. Then, instead of passing the data from each controller method, you can define a view composer in a service provider's boot() method:
Service Provider's boot method
public function boot()
{
View::composer('layouts.partials.sidebar', function ($view) {
//$links = get the data for links
return $view->with('links', $links);
});
}

I am trying to display certain content in my blade files based on if variables are set. But variables are being set that I'm not setting.
I have GameController.php:
use App\Models\Game;
class GameController extends Controller
{
public function index() {
$games = Game::latest()->get();
return view('game.index', [
'games' => $games
]);
}
...
and then in the layout blade file I do this:
#isset($game->name)
<h1>{{ $game->name }}</h1>
#endisset
So I'm setting $games, but I am NOT setting $game. however, $game is set. I want this header to show if I do a show() and $game would be set, but it shouldn't be showing in the index() where $game is not set. Is this normal behavior, and if so what's a better way for me to handle this?
$games = Game::latest()->get();
in code above get() returns collection (may be called array) of games, and you will need #foreach directive in blade template to loop through the games collection.
if you want only one latest game then you should use $games = Game::latest()->first();
I have found the issue. It was lack of understanding of how #extend and #section work.
index.blade.php extends layout.blade.php
#extends ('layout')
it appears all of index processes before layout. Because of that a foreach in index, despite technically being below the header if you were to view source on the web page, was processing before the header and setting $game. I just refactored the variable used in the foreach and that resolved my issue.
Thank you kerbh0lz, you technically helped me find it.
I have a problem understanding how variables work inside the Laravel templating system, Blade.
I set the variables in the controller, I can see them in the first view I make, but not inside the next one.
I'm using a master.blade.php file that holds the header and footer of the page, yielding the content in the middle. I can use the variable inside the master.blade.php file, but not inside the content blade file (variable undefined).
For example, for the contact page:
CONTROLLER FUNCTION:
$this->data['page'] = "contact";
$this->layout->content = View::make('pages.contact');
$this->layout->with('data', $this->data);
MASTER.BLADE.PHP:
if ($data['page'] == 'contact')
{ //do something, it works }
#yield('content')
CONTACT.BLADE.PHP:
if ($data['page'] == 'contact')
{// do something. ErrorException Undefined variable: data}
Am I missing something or is it a known restriction?
Thanks!
The problem was that I was passing the variables only to the layout:
Instead of:
$this->layout->content = View::make('pages.contact');
$this->layout->with('data', $this->data);
I fixed it using:
$this->layout->content = View::make('pages.contact', array('data' => $this->data));
$this->layout->with('data', $this->data);
This way passing the variables to the layout, but also to that particular view.
Hope it helps someone.
I have written a training application with each page/slide of the training workbook as a seperate blade template file named as "page1.blade.php", "page2.blade.php" and so on. Each of these files has content of the kind:
#extends('en/frontend/layouts/training_modulename')
{{-- Page title --}}
#section('title')
Page Title
#parent
#stop
{{-- Page content --}}
#section('pageContent')
<div class="pageContentContainer">
<h2>Page Title</h2>
...
</div>
#stop
This works really well when being viewed page by page within the browser. However I also wish to automatically compile all pages into a PDF document. This is being done via dompdf which works amazingly well when I pass each pages html to it manually. However I wish to condense the #section('pageContent') section of each page into one large section which extends a different layout for passing to dompdf.
Given the above context my question is this:
Is there a method in Laravel's blade parser which would allow me to pass it a blade file and just get the rendered html from a particular section? The below pseudo-code demonstrates what I would like to be able to do.
$pages = array(...); // content of the directory
foreach ($pages as $page)
{
$renderedPage = Blade::render($page);
$title = $renderedPage->title;
$pageContent = $renderedPage->pageContent;
}
Instead of doing the normal return of view
return View::make('page');
You can instead store the view in a string
$view = View::make('page');
So then you can do your code something like this (not tested - but you get the idea):
$pages = array(...); // content of the directory
foreach ($pages as $page)
{
$renderedPage[] = view::make($page);
}
Im using views to display content ,, How can i show block only in the first page in the views and im enable the ajax in the views..
I tried with PHP in the Block visibility but I dont know how to get the first page in the views...
Portfolio = the views name
<?php
$url = request_uri();
$pos = strpos($url, "page");
if ($pos === false && arg(0) =='portfolio') {
return TRUE;
}
?>
you should have different page files for your pages, like "node--product_page.tpl.php"
you can add your view block inside your page, whenever you want using this code:
<?php echo views_embed_view('YourViewName[ex:product_list]', $display_id ='yourBlockViewName[ex:block_1]'); ?>
