Laravel Passing Data From One View to Another View

问题:

I am thinking of making a landing page from the home page, which will direct the guest to the register page. I thought of making two forms for sending data and two submit buttons in them, let's say reader and writer and according to the button they use to go to the register form page, I want to pass the profession string from the button in the landing page and then, place it into the register form in /auth/register.

    {!! Form::open(array('url' => '/auth/register', 'profession' => 'writer')) !!}

    {!! Form::submit('Writer', array('class' => 'btn btn-warning')) !!}

    {!! Form::close() !!}


    {!! Form::open(array('url' => '/auth/register', 'profession' => 'reader')) !!}

    {!! Form::submit('Reader', array('class' => 'btn btn-default')) !!}

    {!! Form::close() !!}

It is not directing me to the page app.com/auth/register. But it works when I directly type the link.

What I thought was using $profession in /auth/register/ and access the value and use it as a hidden field in the registeration form.

(using laravel 5.1)

Edit:

In view source:

    <form method="POST" action="http://app.com/auth/register" accept-charset="UTF-8" profession="writer"><input name="_token" type="hidden" value="dZXQsNI1BGQ39JjDLFUEkSQzL5bTNwe8o3rpiSQL">

    <input class="btn btn-warning" type="submit" value="Writer">

    </form>


    <form method="POST" action="http://app.com/auth/register" accept-charset="UTF-8" profession="reader"><input name="_token" type="hidden" value="dZXQsNI1BGQ39JjDLFUEkSQzL5bTNwe8o3rpiSQL">

    <input class="btn btn-default" type="submit" value="Reader">

    </form>

Edit 2:

    {!! Form::open(array('url' => '/auth/register', 'profession' => 'writer')) !!}

    {!! link_to('/auth/register', 'Writer', array('class' => 'btn btn-default')) !!}

    {!! Form::close() !!}

I tried this instead. At least, now it is directing the page but I still can't access the data value of profession

Edit 3:

Routes:

Route::get('auth/register', 'Auth\AuthController@getRegister');
Route::post('auth/register', 'Auth\AuthController@postRegister');

Route::get('/', function()
{
    return view('pages.home');
});

and https://app.com/auth/register is working.

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 App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Input;

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.
