但此选项不起作用，也不会加载模板，只会显示其本身的内容：

@extends('layout')


@section('content')

<?php
echo "<p>Signing up</p>";

echo Form::open(array('url' => '/users/signup'));
echo Form::label('username', 'Username');
echo Form::text('username');
echo Form::label('email', 'E-Mail Address');
echo Form::text('email');
echo Form::label('Password');
echo Form::password('password');
// echo Form::password('password1', 'Password confirmation');
echo Form::close();

if(!empty ($errors))
{
    foreach ($erros->all() as $error)
    {
        echo '<div class="error">' . $error . '</div>';
    }
}
?>
@stop

我就是不明白为什么一个加载了模板而另一个不加载。

非常感谢您的帮助。

这似乎是您对模板系统的工作方式做出一些未陈述的、可能未实现的假设的情况之一。我要指出你的问题让人困惑的地方，希望这能为你指明正确的方向

Laravel中有两个模板系统。其中一个名为blade，使用如下语法

@extends('layout')

@section('content')
    La de {{$da}}
@stop

<h1>This is a template</h1>
La de <?php echo $da; ?>

第二个使用较少的系统是一个基本的PHP模板系统。i、例如，通过类方法包含一个PHP文件，您可以访问完整的PHP系统。它使用的语法如下所示

@extends('layout')

@section('content')
    La de {{$da}}
@stop

<h1>This is a template</h1>
La de <?php echo $da; ?>

并将模板命名为app/view/example.blade.php，然后Laravel将使用blade系统呈现模板。如果将模板命名为app/view/example.php，Laravel将使用php系统呈现模板

重要提示：只有刀片系统支持模板继承。i、 e.PHP模板没有与@extends和@section等价的内容。您可以通过其他方式来模拟，但PHP模板中没有继承概念

在您的问题中，您没有包含模板的名称，因此我们无法判断它们是由blade还是由PHP呈现的

另外，在第二个模板中，您混合了blade和PHP语法。你不能用切换到PHP，我理解你的问题，但是你的代码对我来说毫无意义

如果您使用的是刀片模板，则更适合使用以下模板：

@extends('layout')

@section('content')

<p>Signing up</p>

{{ Form::open(array('url' => '/users/signup')) }}
{{ Form::label('username', 'Username') }}
{{ Form::text('username') }}
{{ Form::label('email', 'E-Mail Address') }}
{{ Form::text('email') }}
{{ Form::label('Password') }}
{{ Form::password('password') }}
{{ Form::close() }}

@if(!empty ($errors))
    @foreach ($erros->all() as $error)
        <div class="error">' . $error . '</div>';
    @endforeach
@endif
@stop

更干净

如果其中一个工作，而另一个不工作，则应检查以下各项：

@extends('layout')

@section('content')

<p>Signing up</p>

{{ Form::open(array('url' => '/users/signup')) }}
{{ Form::label('username', 'Username') }}
{{ Form::text('username') }}
{{ Form::label('email', 'E-Mail Address') }}
{{ Form::text('email') }}
{{ Form::label('Password') }}
{{ Form::password('password') }}
{{ Form::close() }}

@if(!empty ($errors))
    @foreach ($erros->all() as $error)
        <div class="error">' . $error . '</div>';
    @endforeach
@endif
@stop

1文件的位置。例如，如果它位于“layouts”文件夹中，则需要在文件夹名称前加前缀：

    @extends('layouts.foo')

2文件名的扩展名为.blade.php，例如foo.blade.php，而不是foo.php

3实际文件名，您可能命名不正确，请检查文件的拼写和扩展名

请显示您的控制器foreach$erros->all as$error to foreach$errors->all as$error您可以在blade模板中使用原始php标记，我认为问题出在另一方面，在那里学到了一些新东西。我想我不喜欢那个功能。不管怎样-模板的名称是什么？

@extends('layout')

@section('content')

<p>Signing up</p>

{{ Form::open(array('url' => '/users/signup')) }}
{{ Form::label('username', 'Username') }}
{{ Form::text('username') }}
{{ Form::label('email', 'E-Mail Address') }}
{{ Form::text('email') }}
{{ Form::label('Password') }}
{{ Form::password('password') }}
{{ Form::close() }}

@if(!empty ($errors))
    @foreach ($erros->all() as $error)
        <div class="error">' . $error . '</div>';
    @endforeach
@endif
@stop

    @extends('layouts.foo')
