如何在 Laravel 4 中创建自定义外观
查找了一些关于外观和 laravel 4 的教程...尝试了一些...不喜欢它们的工作方式.
Looked up a few tutorials on facades and laravel 4... tried some... not liked the way they work.
例如，它们并没有提供一种方法来定义存储外观文件和服务提供者的位置......我试图远离它，但我的头撞到了几堵墙上，直到我决定这样做这个话题.
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:假设我有一个名为 Laracms (laravel cms) 的应用程序.
So: Let's say i have an app called Laracms (laravel cms).
我想将我创建的所有内容 - 外观、服务提供者等存储在名为 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.
所以我有/app/laracms/facades、/app/laracms/serviceproviders 等等.我不想将外观与数据库模型混为一谈，我想尽可能地分开.
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.
现在让我们来看看外观的设置名称(我想实现一个设置类以在视图和管理员中使用来设置杂项).
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).
Settings::get(), Settings::set() 作为方法.
Settings::get(), Settings::set() as methods.
谁能解释一下如何正确设置外墙?我不知道我做错了什么，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.
谢谢，克里斯

推荐答案
首先你需要进入 app/config/app.php 并在 providers 部分添加:
First you need to go to app/config/app.php and in providers section add:
'LaracmsProvidersSettingsServiceProvider',
您应该在 aliases 部分的同一文件中添加:
In the same file in aliases section you should add:
'Settings' => 'LaracmsFacadesSettings',
在你的 app/Laracms/Providers 你应该创建文件 SettingsServiceProvider.php
In your app/Laracms/Providers you should create file SettingsServiceProvider.php
<?php
namespace LaracmsProviders;
use IlluminateSupportServiceProvider;
class SettingsServiceProvider extends ServiceProvider {
public function register()
{
$this->app->bind('settings', function()
{
return new LaracmsSettings();
});
}
}
在你的 app/Laracms/Facades/ 你应该创建文件 Settings.php:
In your app/Laracms/Facades/ you should create file Settings.php:
<?php
namespace LaracmsFacades;
use IlluminateSupportFacadesFacade;
class Settings extends Facade {
protected static function getFacadeAccessor() { return 'settings'; }
}
现在在您的 app/Laracms 目录中，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"; }
}
由于您希望将文件放在自定义文件夹 Laracms 中，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，您无需向此文件添加任何内容).所以现在打开 composer.json 文件并在 autoload -> classmap 部分添加 app/Laracms 所以这个composer.json 的部分可能如下所示:
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"
]
},
现在您需要在项目文件夹中的控制台中运行:
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，您现在应该可以在应用程序中使用 Settings::get() 和 Settings:set()
If everything is fine, you should now be able to use in your applications Settings::get() and Settings:set()
您需要注意我使用了大写的文件夹，因为按照约定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.
