Laravel 8.0 Blade 嵌套 @extends @section 和 @yield 不起作用

Question

我有这个template.blade.php，路径为views/templates/template.blade.php，代码如下：

// template.blade.php


// some codes here

@include("templates.navigation.navigation")
@yield('header')
@yield('content')
@include('templates.footer.footer')

// some other codes here

现在，在我的路线中，home.blade.php（可通过views/home/home.blade.php 访问）被设置为着陆页。主页需要借用一段代码（浮动按钮的代码。每个浮动按钮根据当前页面的不同而不同）。这是主页的代码：

// home.blade.php


@extends('templates.template')
@section('header')
    // some codes here
@endsection

@section('content')
    // some other codes here
    @yield('float-button-module-menu') // the code that needs to be accessed but doesn't work
@endsection

@yield('float-button-module-menu') 将通过views/templates/float-buttons/float-buttons.blade.php 访问。这是上述网页的代码：

// float-buttons.blade.php


@extends('home.home') // I suspect that I was wrong at declaring the name for the @extends here
@section('float-button-module-menu')
    // some codes inside the section that needs to be displayed
@endsection

为了简化问题，我需要从float-buttons.blade.php 中的home.blade.php 访问@section('float-button-module-menu')。我不知道这个逻辑中的问题。

编辑这里是float-button.blade.php内部分的完整代码：

// float-button.blade.php


@extends('home.home')
@section('float-button-module-menu')
<div class="d-flex flex-column position-fixed button button-float-position-buttom-left">
    <div class="button-float d-flex">
        <span class="fas fa-user-cog text-lg text-white align-self-center mx-auto"></span>
    </div>
</div>
@endsection

@section('float-button-anchor')
<div class="button-float d-flex">
    <span class="fas fa-arrow-up text-lg text-white align-self-center mx-auto"></span>
</div>
@endsection

@section('float-button-help')
<div class="button-float d-flex">
    <span class="fas fa-question text-lg text-white align-self-center mx-auto"></span>
</div>
@endsection

// list of buttons would be updated.

Answer 1

扩展视图适用于您直接调用/查看刀片文件时，例如通过return view('templates.float-buttons.float-buttons')。听起来这不是你要找的。你想@includehome.blade.php 中的文件。进行以下更改：

home.blade.php：

@extends('templates.template')
@section('header')
    // some codes here
@endsection

@section('content')
    // some other codes here
    @include('templates.float-buttons.float-buttons')
@endsection

浮动按钮.blade.php：

<div>
  My Float Buttons Code
</div>

float-buttons.blade.php 将只包含浮动按钮的代码

第二部分

including subviews 时可以将参数传递给@include。看看这些更改是否适合您的需求：

home.blade.php

@extends('templates.template')
@section('header')
    // some codes here
@endsection

@section('content')
    // some other codes here
    @include('templates.float-buttons.float-buttons', ['type' => 'anchor'])
@endsection

浮动按钮.blade.php：

@if ($type == 'anchor')
<div class="button-float d-flex">
    <span class="fas fa-arrow-up text-lg text-white align-self-center mx-auto"></span>
</div>

@elseif ($type == 'help')
<div class="button-float d-flex">
    <span class="fas fa-question text-lg text-white align-self-center mx-auto"></span>
</div>

@else
{{-- if no type parameter is given --}}
<p>
  Parameter 'type' is required
</p>
@endif

然后，您基本上可以在任何需要的地方使用@include('templates.float-buttons.float-buttons', ['type' => 'anchor']) 或@include('templates.float-buttons.float-buttons', ['type' => 'help'])。当然也可以随意扩展列表

注意：恕我直言，更优雅的解决方案是为每个案例创建单个刀片文件（'float-buttons-anchor.blade.php, float-buttons-help.blade.php...) and then include the file you need:@include ('templates.float-buttons.float-buttons-help')
