I'm aware that Laravel-blade allows us to define sections of code, but I'm wondering if it's possible to clear, or redefine a section within the same file as where it's been defined.
For example, something like:
#section('scripts')
<script src="/example.js"></script>
#endsection
//something like
#section('scripts')
// nothing
#endsection
// now the 'scripts' stack is an empty block of code.
//print
{{ #yield('scripts') }}
I've figured out a way to do it, by simply using ob_start() in regular php instead.
#php
ob_start();
#endphp
// write blade code here
#php
$scripts = ob_get_contents();
ob_end_clean();
#endphp
//print
{!! $scripts !!}

Hi I am trying to get the content within a div element that also happens to be within a form into my controller. I dont want to use ajax. How may I get that done ?
<div id="editorcontents" name="editorcontents">
</div>
Then in controller
Use Input;
$content = Input::get('editorcontents');
In your controller, do something like this. Look up the correct way in the docs (https://laravel.com/docs/5.4/eloquent#retrieving-models). For example, if you want ALL input, you would do Input::all();, instead of Input::where('editorcontents')->get();
public function index() {
$content = Input::where('editorcontents')->get();
return view('your_view.blade.file', compact('content'));
}
Then in your view your would now have $content, that you passed from your controller.
start of by looking at it, add this at top of your view: {{ dd($content) }}. This will die dump $content.
Go ahead and remove that line and do something like (docs here https://laravel.com/docs/5.4/blade#loops):
<div id="editorcontents" name="editorcontents">
#forelse ($content as $value)
<li>{{ $value->body }}</li>
#empty
<p>No content</p>
#endforelse
</div>
I have this blade view template
<title><?
$page = App::make('page');
echo $page->getTitle( );
?></title>
<?php
$css = $page->getCssList('all');
foreach($css as $item){?>
{{ HTML::style('<?=$item['loc'];?>', array('media' => '<?=$item['media'];?>'))}}
<?}
$js = $page->getJsList('all');
foreach($js as $item){?>
{{ HTML::script('<?=$item['loc'];?>')}}
<?}?>
It does not work. What happens is it actually outputs the blade commands to the screen.
If i cut and paste these blade command into the view then they are rendered correctly.
What is the problem? Is is not possible to create dynamic blade commands? How can I solve this problem?
You are using PHP inside of PHP.
Change this
{{ HTML::script('<?=$item['loc'];?>')}}
to this
{{ HTML::script($item['loc']) }}
and change
{{ HTML::style('<?=$item['loc'];?>', array('media' => '<?=$item['media'];?>'))}}
to
{{ HTML::style($item['loc'], array('media' => $item['media'])) }}
The curly braces are simply a shortcut for printing PHP code.
You can just write
{{ HTML::script($item['loc']) }}
Which is functionally identical to
<?php echo HTML::script($item['loc']); ?>
Is it possible to check into a blade view if #yield have content or not?
I am trying to assign the page titles in the views:
#section("title", "hi world")
So I would like to check in the main layout view... something like:
<title> Sitename.com {{ #yield('title') ? ' - '.#yield('title') : '' }} </title>
For those looking on it now (2018+), you can use :
#hasSection('name')
#yield('name')
#endif
See : https://laravel.com/docs/5.6/blade#control-structures
In Laravel 5 we now have a hasSection method we can call on a View facade.
You can use View::hasSection to check if #yeild is empty or not:
<title>
#if(View::hasSection('title'))
#yield('title')
#else
Static Website Title Here
#endif
</title>
This conditional is checking if a section with the name of title was set in our view.
Tip: I see a lot of new artisans set up their title sections like this:
#section('title')
Your Title Here
#stop
but you can simplify this by just passing in a default value as the second argument:
#section('title', 'Your Title Here')
The hasSectionmethod was added April 15, 2015.
There is probably a prettier way to do this. But this does the trick.
#if (trim($__env->yieldContent('title')))
<h1>#yield('title')</h1>
#endif
Given from the docs:
#yield('section', 'Default Content');
Type in your main layout e.g. "app.blade.php", "main.blade.php", or "master.blade.php"
<title>{{ config('app.name') }} - #yield('title', 'Otherwise, DEFAULT here')</title>
And in the specific view page (blade file) type as follows:
#section('title')
My custom title for a specific page
#endsection
#hasSection('content')
#yield('content')
#else
\\Something else
#endif
see "Section Directives" in If Statements - Laravel docs
You can simply check if the section exists:
if (isset($__env->getSections()['title'])) {
#yield('title');
}
And you can even go a step further and pack this little piece of code into a Blade extension: http://laravel.com/docs/templates#extending-blade
Complete simple answer
<title> Sitename.com #hasSection('title') - #yield('title') #endif </title>
I have a similar problem with the solution:
#section('bar', '')
#hasSection('bar')
<div>#yield('bar')</div>
#endif
//Output
<div></div>
The result will be the empty <div></div>
Now, my suggestion, to fix this, is
#if (View::hasSection('bar') && !empty(View::yieldContent('bar')))
<div>#yield('bar')</div>
#endif
New in Laravel 7.x -- sectionMissing():
#hasSection('name')
#yield('name')
#else
#yield('alternative')
#endif
Check if section is missing:
#sectionMissing('name')
#yield('alternative')
#endif
#if (View::hasSection('my_section'))
<!--Do something-->
#endif
Use View::hasSection to check if a section is defined and View::getSection to get the section contents without using the #yield Blade directive.
<title>{{ View::hasSection('title') ? View::getSection('title') . ' - App Name' : 'App Name' }}</title>
I don't think you can, but you have options, like using a view composer to always provide a $title to your views:
View::composer('*', function($view)
{
$title = Config::get('app.title');
$view->with('title', $title ? " - $title" : '');
});
why not pass the title as a variable View::make('home')->with('title', 'Your Title') this will make your title available in $title
Can you not do:
layout.blade.php
<title> Sitename.com #section("title") Default #show </title>
And in subtemplate.blade.php:
#extends("layout")
#section("title") My new title #stop
The way to check is to not use the shortcut '#' but to use the long form: Section.
<?php
$title = Section::yield('title');
if(empty($title))
{
$title = 'EMPTY';
}
echo '<h1>' . $title . '</h1>';
?>
Building on Collin Jame's answer, if it is not obvious, I would recommend something like this:
<title>
{{ Config::get('site.title') }}
#if (trim($__env->yieldContent('title')))
- #yield('title')
#endif
</title>
Sometimes you have an enclosing code, which you only want to have included in that section is not empty. For this problem I just found this solution:
#if (filled(View::yieldContent('sub-title')))
<h2>#yield('sub-title')</h2>
#endif
The title H2 gets only displayed it the section really contains any value. Otherwise it won't be printed...
I have an application without controllers and read about controller layouts in laravel 4 documentation and this other article too, but I don't know where to start for implement it within routes (version 4), how can I do that?
Error received: InvalidArgumentException, View [master] not found.
app/routes.php
<?php
View::name('layouts.master', 'layout');
$layout = View::of('layout');
Route::get('users/create', array('as' => 'users.create', function() use($layout) {
//#TODO: load view using 'layouts.master',
// desirable: append 'users.create' and 'users.menu' views to sidebar and content sections.
//return View::make('users.create');
return $layout->nest('content', 'master');
}));
?>
app/views/layouts/master.blade.php
<html>
<body>
#section('sidebar')
This is the master sidebar.
#show
<div class="container">
#yield('content')
</div>
</body>
</html>
app/views/users/create.blade.php
{{ Form::open() }}
{{ Form::text('name') }}
{{ Form::submit('submit') }}
{{ Form::close() }}
app/views/users/menu.blade.php
<!-- This is appended to the master sidebar -->
<p>Create user</p>
Update: I modified example code to clarify what I want to do. Check app/routes.php and its comments
The code in your routes file is trying to nest the master layout within itself, which isn't really what you want. You're getting the error because 'master' would look for app/views/master.blade.php. That's easily fixed by changing it to 'layouts.master', but I wouldn't like to think what might happen...
The root cause of the issue you're having is the difference between "yielding" views from a Blade template, and nesting them from a route. When you nest a route, you need to echo it rather than using the #yield tag.
// File: app/routes.php
View::name('layouts.master', 'layout');
$layout = View::of('layout');
Route::get('users/create', array('as' => 'users.create', function() use ($layout)
{
return $layout
->nest('content', 'users.create')
->nest('sidebar', 'users.menu');
}));
/*

*/
View::composer('layouts.master', function($view)
{
if (!array_key_exists('sidebar', $view->getData()))
{
$view->with('sidebar', '');
}
});
// File: app/views/layouts/master.blade.php
<html>
<body>
#section('sidebar')
This is the master sidebar
{{ $sidebar }}
#show
<div class="container">
{{ $content }}
</div>
</body>
</html>
Laravel's View composers are a powerful tool. If you have any data (eg logged-in user info) used by all views that share the same template(s), you can use the composers to save injecting the data every time you load the view.
You could also use the #parent tag to append content, assuming you;re using blade for templating. E.g. (in the view)
#section('sidebar')
#parent
<p>This is appended to the master sidebar.</p>
#stop
You don't need to use nesting views if you're using blade.
app/views/users/create.blade.php
You need to extend the master.blade
#extends('layouts.master')
#section('content')
// form stuff here
#stop
Now, all you need to do is call create.blade
return View::make('users.create')
Just throwing this out there as a possible solution using controller routing (whereas you can set the template from within the controller).
app/routes.php
Route::controller('something', 'SomethingController');
app/controllers/SomethingController.php
class SomethingController extends BaseController {
protected $layout = "templates.main"; // denotes views/templates/main.blade.php
public function getIndex() { // the "landing" page for "/something" or "/something/index"
$this->layout->content = View::make('something.index')->with("myVar", "Hello, world!"); // load in views/something/index.blade.php INTO main.blade.php
}
public function getTest() { // for "/something/test"
$this->layout->content = View::make('something.index')->nest("widget", "something.widget", array("myVar" => "Hello, World!"));
}
}
app/views/templates/main.blade.php
#include('templates.partials.header')
#yield('something')
#yield('content')
#include('templates.partials.footer')
app/views/something/widget.blade.php
I'm a widget. {{ $myVar }}
app/views/something/index.blade.php
#section('something')
I will go in the 'something' yield in main.blade.php
#stop
#section('content')
I will go in the 'content' yield in main.blade.php.
{{ $myVar }}
{{ $widget }}
#stop
?>
Now you can test http://myserver/something and http://myserver/something/test to see the differences. Note: not tested but as a rough example.
How can i use something like {{#something}} and it will run a controller that checks for "something" so i can return it to translteable text?
My current blade template looks like following:
#layout("layouts.default")
#section("inner")
<h1>Velkommen til pornobiksen</h1>
#foreach($videos as $thumb)
{{$thumb}}
#endforeach
#endsection
I mean, how can i change the "Velkommen til pornobiksen" tekst? I know i can make something like
View::make("template")->with("h1_text","Velkommen til pornobiksen");
But is there not a module/plugin to make it easier? By making like {{#h1_text}} and it will takes from my database or something?
What is the easists way to make this?
You need to use {{ $h1_text }} to put the variable into your blade template.
#layout("layouts.default")
#section("inner")
<h1>{{ $h1_text }}</h1>
#foreach($videos as $thumb)
{{$thumb}}
#endforeach
#endsection
EDIT
I think I misunderstood you, it seems you are looking for localization
#layout("layouts.default")
#section("inner")
<h1>{{ Lang::get('messages.welcome') }}</h1>
#foreach($videos as $thumb)
{{$thumb}}
#endforeach
#endsection
For localization , you can use helper function : trans
home.php
return [
'welcome' => 'Velkommen til pornobiksen'
];
View
#layout("layouts.default")
#section("inner")
<h1>{{trans('home.welcome')}}</h1>
#foreach($videos as $thumb)
{{$thumb}}
#endforeach
#endsection
