Here's a step by step walkthrough on how to implement it. I tested it. So it works. This is for 'writer', but you could replicate it as you had originally planned for other professions.
I assume you've registered the Laravel Collective package since you're using the curly braces and exclamation points.
Step 1:
In your landing page view, where you have the writer button, add a hidden field with the string 'writer'. Like this:
{!! Form::open(['route' => ['writer_path']]) !!}
{!! Form::hidden('profession', 'writer') !!}
{!! Form::submit('Writer', array('class' => 'btn btn-warning')) !!}
{!! Form::close() !!}
Not that in the open field we are using a named route ('writer_path').
Step 2:
Register a route and a controller on your routes.php file, like this:
Route::post('auth/register', [
'as' => 'writer_path',
'uses' => 'SampleController@displayForm'
]);
Step 3:
In your sample controller, you define the displayForm method.
Within that method you first obtain the value you passed from the landing page view.
If you don't know how to create a controler, you can do
php artisan make:controller SampleController
from the command line
Because the value arrives as an array, you have to obtain the string 'writer' from the array and then pass it to the new view (the view with the registration form for the writer).
<?php
namespace AppHttpControllers;
use IlluminateHttpRequest;
use AppHttpRequests;
use AppHttpControllersController;
use IlluminateSupportFacadesInput;
class SampleController extends Controller
{
/**
* Display a listing of the resource.
*
* @return Response
*/
public function displayForm()
{
$input = Input::get();
$profession = $input['profession'];
return view('writerregistration', ['profession' => $profession]);
}
}
Last Step:
In the new view which you will create as writerregistration.blade.php, you will display the form with the field you just passed ('profession') which contains the string 'writer'. Like this:
{!! Form::open() !!}
{!! Form::label('username', 'Username:') !!}
{!! Form::text('username', null, ['class' => 'form-control']) !!}
{!! Form::label('profession', 'Profession:') !!}
{!! Form::text('profession', $profession, ['class' => 'form-control']) !!}
{!! Form::label('email', 'Email:') !!}
{!! Form::text('email', null, ['class' => 'form-control']) !!}
{!! Form::label('passowrd', 'Password:') !!}
{!! Form::password('password', ['class' => 'form-control']) !!}
{!! Form::label('password_confirmation', 'Password Confirmation:') !!}
{!! Form::password('password_confirmation', ['class' => 'form-control']) !!}
{!! Form::submit('Sign Up', ['class' => 'btn btn-primary']) !!}
{!! Form::close() !!}
Presto, you've populated the field in the registration form for the writer with the info on the hidden field that belonged to the writer button in the landing page.
