Laravel-控制器功能之间共享变量

Question

我是Laravel的新手，正在从事一个简单的项目，在我的控制器（TestController）中，我有两个功能（process和show） 。

我想做的是在函数之间传递$ email变量，因此我可以在show函数中使用它，但是我不知道该怎么做。

调节器

class TestController extends Controller
{    

    public function process(Request $request){
        if($request->ajax()) {
            $email = $request->get( "fullemail" );
        }
    }


    public function show(){

    }

}

任何帮助，将不胜感激。 提前致谢 ：）

我按如下方式编辑了代码。 目前，我得到的Too few arguments to function App\\Http\\Controllers\\TestController::show(), 0 passed and exactly 1 expected错误。

class TestController extends Controller
{    
    public function process(Request $request){
        if($request->ajax()) {
            $email = $request->get( "fullemail" );
            $this->show($email);
        }
    }

    public function show($email){
        dd($email)
    }
}

如果您已经接触到laravel并且知道什么功能，那么您可能已经知道如何执行此操作：

class TestController extends Controller
{    

    public function process(Request $request){
        if($request->ajax()) {
            $email = $request->get( "fullemail" );
            $this->show($email);
        }
    }


    public function show($email){
        // Do whatever you will with the $email variable.
        return view('some.view', ['email' => $email]);
    }

}

替代方法：

class TestController extends Controller
{    

    // Declare this variable as a class property - protected means, that only this class and any class that inherits from this class can access the variable.
    protected $email;

    public function process(Request $request){
        if($request->ajax()) {
            $this->email = $request->get( "fullemail" );
            $this->show();
        }
    }


    public function show() {
        // Do whatever you will with the $email variable.
        return view('some.view', ['email' => $this->email]);
        // On top of that, if you change $email value here, the changes will be available in all other methods as well.
        // $this->email = strtolower($this->email);
    }

}
