Blade Templating
Blade is a simple, yet powerful templating engine provided with Laravel. Unlike controller layouts, Blade is driven by template inheritance and sections. All Blade templates should use the .blade.php extension.
Defining A Blade Layout
<!-- Stored in resources/views/layouts/master.blade.php -->
<html>
<head>
<title>App Name - @yield('title')</title>
</head>
<body>
@section('sidebar')
This is the master sidebar.
@show
<div class="container">
@yield('content')
</div>
</body>
</html>
Using A Blade Layout
@extends('layouts.master')
@section('title', 'Page Title')
@section('sidebar')
@@parent
<p>This is appended to the master sidebar.</p>
@stop
@section('content')
<p>This is my body content.</p>
@stop
Note that views which extend a Blade layout simply override sections from the layout. Content of the layout can be included in a child view using the @@parent directive in a section, allowing you to append to the contents of a layout section such as a sidebar or footer.
Sometimes, such as when you are not sure if a section has been defined, you may wish to pass a default value to the @yield directive. You may pass the default value as the second argument:
@yield('section', 'Default Content')
Other Blade Control Structures
Echoing Data
Hello, {{ $name }}.
The current UNIX timestamp is {{ time() }}.
Echoing Data After Checking For Existence
Sometimes you may wish to echo a variable, but you aren't sure if the variable has been set. Basically, you want to do this:
{{ isset($name) ? $name : 'Default' }}
However, instead of writing a ternary statement, Blade allows you to use the following convenient short-cut:
{{ $name or 'Default' }}
Displaying Raw Text With Curly Braces
If you need to display a string that is wrapped in curly braces, you may escape the Blade behavior by prefixing your text with an @ symbol:
@{{ This will not be processed by Blade }}
If you don't want the data to be escaped, you may use the following syntax:
Hello, {!! $name !!}.
Note: Be very careful when echoing content that is supplied by users of your application. Always use the double curly brace syntax to escape any HTML entities in the content.
If Statements
@if (count($records) === 1)
I have one record!
@elseif (count($records) > 1)
I have multiple records!
@else
I don't have any records!
@endif
@unless (Auth::check())
You are not signed in.
@endunless
Loops
@for ($i = 0; $i < 10; $i++)
The current value is {{ $i }}
@endfor
@foreach ($users as $user)
<p>This is user {{ $user->id }}</p>
@endforeach
@forelse($users as $user)
<li>{{ $user->name }}</li>
@empty
<p>No users</p>
@endforelse
@while (true)
<p>I'm looping forever.</p>
@endwhile
Including Sub-Views
@include('view.name')
You may also pass an array of data to the included view:
@include('view.name', ['some' => 'data'])
Overwriting Sections
To overwrite a section entirely, you may use the overwrite statement:
@extends('list.item.container')
@section('list.item.content')
<p>This is an item of type {{ $item->type }}</p>
@overwrite
Displaying Language Lines
@lang('language.line')
@choice('language.line', 1)
