模板输出

基本输出

<!-- app/views/example.blade.php -->
<p>{{ date('d/m/y') }}</p>

原样输出

<!-- app/views/example.blade.php -->
<p>{{{ '<script>alert("CHUNKY BACON!");</script>' }}}</p>

特殊字符串将被自动转义，最终结果如下：

<!-- app/views/example.blade.php -->
<p>&lt;script&gt;alert(&quot;CHUNKY BACON!&quot;);&lt;/script&gt;</p>

控制结构

if

<!-- app/views/example.blade.php -->
@if ($something == 'Red Panda')
    <p>Something is red, white, and brown!</p>
@elseif ($something == 'Giant Panda')
    <p>Something is black and white!</p>
@else
    <p>Something could be a squirrel.</p>
@endif

foreach

<!-- app/views/example.blade.php -->
@foreach ($manyThings as $thing)
    <p>{{ $thing }}</p>
@endforeach

for

<!-- app/views/example.blade.php -->
@for ($i = 0; $i < 999; $i++)
    <p>Even {{ $i }} red pandas, aren't enough!</p>
@endfor

while

<!-- app/views/example.blade.php -->
@while (isPretty($kieraKnightly))
    <p>This loop probably won't ever end.</p>
@endwhile

unless

<!-- app/views/example.blade.php -->
@unless (worldIsEnding())
    <p>Keep smiling.</p>
@endunless

模板引用

<!-- app/views/header.blade.php -->
<h1>When does the Narwhal bacon?</h1>

<!-- app/views/footer.blade.php -->
<small>Information provided based on research as of 3rd May '13.</small>

<!-- app/views/example.blade.php -->
<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Narwhals</title>
</head>
<body>
    @include('header')
    <p>Why, the Narhwal surely bacons at midnight, my good sir!</p>
    @include('footer')
</body>
</html>

模板继承

<!-- app/views/layouts/base.blade.php -->
<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title></title>
    @section('head')
        <link rel="stylesheet" href="style.css" />
    @show
</head>
<body>
    @yield('body')
    @section('message')
        @parent
        <p>parent message.</p>
    @show
</body>
</html>

<!-- app/views/home.blade.php -->
@extends('layouts.base')
@section('head')
    <link rel="stylesheet" href="another.css" />
@stop
@section('body')
    <h1>Hurray!</h1>
    <p>We have a template!</p>
@stop
@section('message')
    @parent
    <p>Fourth</p>
@stop
