How to call custom helper in laravel 5?
提问by Reynald Henryleo
I wanna make my very own helper, and i put it in app/http/helpers.php.
This is my helper code:
我想做我自己的帮手，我把它放进去app/http/helpers.php。这是我的帮助代码：
<?php
namespace App\Helpers;
use Auth;
class helper {
public static function is_login() {
if(Auth::check()){
return True;
}else{
return False;
}
}
public static function must_login(){
if(Auth::check()){
return True;
}else{
return Redirect::to('logout');;
}
}
}
?>
and this is my app.php code:
这是我的 app.php 代码：
'aliases' => [
'customhelper'=> App\Helpers\Helper::class
]
when i use for my blade file customhelper::is_login()it work. But when i try to use in my controller customhelper::must_login()it doesn't work and i've got some error
当我用于刀片文件时，customhelper::is_login()它可以工作。但是当我尝试在我的控制器中使用customhelper::must_login()它时它不起作用并且我遇到了一些错误
Class 'App\Http\Controllers\customhelper' not found
找不到类“App\Http\Controllers\customhelper”

Use your alias with the same name of Helper Class and add use statement to Controller file.
使用与 Helper Class 同名的别名并将 use 语句添加到 Controller 文件中。
For Example :
例如 ：
app/Helpers/Helper.php
app/Helpers/Helper.php
<?php
namespace App\Helpers;
class Helper{
public static function SayHello()
{
return "SayHello";
}
}
config/app.php
config/app.php
'aliases' => [
/*Defaults...*/
'Helper' => App\Helpers\Helper::class,
],
app/Http/Controllers/MyController.php
app/Http/Controllers/MyController.php
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Helper; // Important
class MyController extends Controller
{
public function index()
{
return Helper::SayHello();
}
}

First thing like you have mentioned 'app/http/helpers.php'your helper file path in that case your namespace should be 'namespace App\Http'.
喜欢你的第一件事提到'app/http/helpers.php'在这种情况下，你的命名空间应该是你的帮手文件路径'namespace App\Http'。
for better understanding to make global helper function refer 'Custom Classes in Laravel 5, the Easy Way'section of Best practices for custom helpers on Laravel 5
为了更好地理解使全局助手功能，请参阅Laravel 5上自定义助手的最佳实践的“Laravel 5 中的自定义类，简单方法”部分
