如何创建自定义门面在Laravel 4 [英] How to create custom Facade in Laravel 4

问题描述

在外墙和laravel 4上查看了几个教程...尝试了一些...不喜欢他们的工作方式。

Looked up a few tutorials on facades and laravel 4... tried some... not liked the way they work.

例如，他们不所有提供一种方式来定义在哪里存储立面文件和服务提供商...我试图离开那里，让我的头撞到几个墙，直到我决定做这个线程。

For instance, they don't all provide a way of defining where to store the facade files and service providers... and i tried to step away from that and got my head bumped into a few walls until i decided to do this thread.

所以：假设我有一个应用程序叫Laracms（laravel cms）。

So: Let's say i have an app called Laracms (laravel cms).

我想将我创建的所有内容 - 外墙，服务提供商等存储在名为laracms的应用程序下的文件夹中。

I'd like to store everything i create - facades, service providers, etc in a folder under app named laracms.

所以我会有/ app / laracms / facades，/ app / laracms / serviceproviders等等。我不想将外观与数据库模型混合，我想尽可能保持独立。

So i'd have /app/laracms/facades, /app/laracms/serviceproviders and so on. I don't want to mix the facades with the database models, i want to keep things as separate as possible.

现在让我们来看一下设置名称对于立面（我想实现一个设置类使用视图和管理员设置杂项。）

Let's take now, in my case, the Settings name for the facade (i want to implement a settings class to use in views and admin to set up misc. stuff).

设置:: get（），设置： set（）作为方法。

Settings::get(), Settings::set() as methods.

任何人都可以解释如何正确设置外观？我不知道我做错了，我需要一个新的开始。

Can anyone explain how to set facades up correctly? I don't know what i'm doing wrong and i need a fresh start.

感谢您，
Chris

推荐答案

首先，您需要转到 app / config / app.php 和提供程序部分添加：

First you need to go to app/config/app.php and in providers section add:

'Laracms\Providers\SettingsServiceProvider',

在别名 section您应该添加：

In the same file in aliases section you should add:

 'Settings' => 'Laracms\Facades\Settings',

在您的应用程式/ Laracms / Providers ，您应该创建文件 SettingsServiceProvider.php

In your app/Laracms/Providers you should create file SettingsServiceProvider.php

<?php

namespace Laracms\Providers;

use Illuminate\Support\ServiceProvider;

class SettingsServiceProvider extends ServiceProvider {

    public function register()
    {
        $this->app->bind('settings', function()
            {
                return new \Laracms\Settings();
            });
    }

}

> app / Laracms / Facades / 您应该创建文件 Settings.php ：

In your app/Laracms/Facades/ you should create file Settings.php:

<?php

namespace Laracms\Facades;

use Illuminate\Support\Facades\Facade;

class Settings extends Facade {

    protected static function getFacadeAccessor() { return 'settings'; }

}

现在在 Laracms 目录您应该创建文件 Settings.php ：

Now in your app/Laracms directory you should create file Settings.php:

<?php

namespace Laracms;

class Settings {
   public function get() {echo "get"; }

   public function set() {echo "set"; }
}

由于您希望自定义文件夹中的文件 Laracms 您需要将此文件夹添加到您的 composer.json （如果您使用标准 app / models 文件夹，你不需要添加任何东西到这个文件）。所以现在打开 composer.json 文件和 autoload - > classmap 您应该添加 app / Laracms ，因此composer.json的这一部分可能如下所示：

As you wanted to have your files in custom folder Laracms you need to add this folder to your composer.json (If you used standard app/models folder you wouldn't need to add anything to this file). So now open composer.json file and in section autoload -> classmap you should add app/Laracms so this section of composer.json could look like this:

"autoload": {
    "classmap": [
        "app/commands",
        "app/controllers",
        "app/models",
        "app/database/migrations",
        "app/database/seeds",
        "app/tests/TestCase.php",
        "app/Laracms"
    ]
},

现在您需要在您的控制台foler：

Now you need to run in your console inside your project foler:

composer dump-autoload

创建类映射

如果一切正常，您现在应该可以在您的应用程序中使用 :: get（）和设置：set（）

If everything is fine, you should now be able to use in your applications Settings::get() and Settings:set()

我使用带大写字母的文件夹，因为按照惯例，命名空间以大写字母开头。

You need to notice that I used folders with uppercases because namespaces by convention starts with upper letters.
