How to add custom value to Auth::user() in Laravel
提问by Parth Vora
I've some custom value that I want to use in the whole project when the user logs in. I am writing a function in controllers but calling that static method every time can make code little bit lengthy. Instead of calling the function I want to assign a custom value to Auth::user()so I can use it anywhere in the project. I tried it below code but it won't work
当用户登录时，我想在整个项目中使用一些自定义值。我正在控制器中编写一个函数，但每次调用该静态方法都会使代码有点冗长。我想为其分配自定义值而不是调用函数，Auth::user()以便我可以在项目中的任何地方使用它。我在下面的代码中尝试过，但它不起作用
public static function getUserDetailById($id){
//Do Something and assign value to $custom_val
Auth::user()->custom = $custom_val;
}
But It's not working in any controller or view. I tried to check custom value in Auth::user()but it's missing.
但它不适用于任何控制器或视图。我试图检查自定义值，Auth::user()但它丢失了。
Is there any way to add custom value to Auth::user()without adding new column in a table?
有什么方法可以添加自定义值Auth::user()而不在表中添加新列？

It is very simple. You can create an Accessor for that.
这很简单。您可以为此创建一个访问器。
App\User.php
应用\用户.php
public function getCustomAttribute()
{
return 'Custom attribute';
}
Now, you can access it anywhere using:
现在，您可以使用以下方式在任何地方访问它：
echo Auth::user()->custom;

添加custom到您的User模型$appends数组。
