如何将值从一个 controller 传递到 LARAVEL 中的另一个？

Question

GOALS: I want to pass autograph database data to ImageUploadController.php from AutographController.php basically to determine if the data already existed in the Database.

---

What I've Done:

if (Autograph::where("$autograph", '=', Input::get('autograph'))->exists()) {
echo "Autograph Registered.";
}

---

But it's giving me this error

Facade\Ignition\Exceptions\ViewException

Class 'App\Http\Controllers\Autograph' not found (View: C:\xampp\htdocs\PKL_DSV\resources\views\imageUpload.blade.php)

i already imported use App\Http\Controllers\AutographController;

Answer 1

you have to import your model by adding use App\Autograph not use App\Http\Controllers\AutographController

Answer 2

Try this,

App\Autograph::where("$autograph", '=', Input::get('autograph'))

and make sure to use correct namespace. Also, do not pass data between controllers, use models to do whatever you want. If you've to pass data, you can use sessions and flush sessions after use.
