I want to send user to payment gate. Normally it could be made by this form:
It could help you use the Laravel controller as usual and redirect after to the external resource.
In your view redirect the action to your controller:
In your controller:
public function method(Request $request)
{
// Validate
// Store
// ...
Redirect::away('https://demo.moneta.ru/assistant.htm')->withInputs(Input::all());
}
I didn't test it, but I'm pretty sure that it works (or is near to the solution).
You can get other suggestion from the official guide: http://laravel.com/docs/5.1/responses#redirects
