Laravel PayPal tutorial into real world scenario - php

Question

I have been following the tutorial on http://laravelcode.com/post/how-to-integrate-paypal-payment-gateway-in-laravel-54
I'm now trying to use this in an an application i'm developing but i'm quite new to PHP/Laravel so trying to get these paypal functions into my own Controller/forms that I have already built.
I have a controller "BookingsController" which has a form on ../bookings/create that when the EU presses the submit button it will enter the info into the DB, which works perfect, and then runs the PayPal bits to take the EU to the PayPal checkout which is where i've come unstuck.
My Controller:-
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Market;
use App\Stall;
use App\Booking;
use Auth;
use GuzzleHttp\Transaction;
class BookingsController extends Controller
{
/**
* Display a listing of the resource.
*
* #return \Illuminate\Http\Response
*/
public function index()
{
//
}
/**
* Show the form for creating a new resource.
*
* #return \Illuminate\Http\Response
*/
public function create()
{
$market = Market::where('is_active', true)->orderBy('name')->pluck('name','id');
$stall = Stall::pluck('name','id')->all();
return view ('bookings.create', compact('market','stall'));
}
/**
* Store a newly created resource in storage.
*
* #param \Illuminate\Http\Request $request
* #return \Illuminate\Http\Response
*/
public function store(Request $request)
{
$this->validate($request, [
'name' => 'required',
'email' => 'email',
'address' => 'required',
'phone' => 'required',
]);
//Uncomment the below line to test form values
// return $request->all();
$booking = new Booking;
$booking->name = $request->input('name');
$booking->email = $request->input('email');
$booking->address = $request->input('address');
$booking->phone = $request->input('phone');
$booking->market_id = $request->input('market_id');
$booking->stall_id = $request->input('stall_id');
$booking->itemtype = $request->input('itemtype');
$booking->clothesrail = $request->input('clothesrail');
$booking->businessname = $request->input('businessname');
$booking->insurance = $request->input('insurance');
//Get the stall cost
//$stallPrice = Stall::pluck('cost')->where('id', '=', $booking->stall_id);
$stallPrice = 15;
//Check if the user is logged in. If so then submit the user_id
if (Auth::check())
{
$booking->user_id = auth()->user()->id;
}
//return $stallPrice;
//$booking->save();
//Redirect user based on logged in session_status
if (Auth::check())
{
return redirect('/dashboard')->with('success', 'Stall Booked!');
}
return redirect('/confirm')->with('success', 'Stall Booked!');
}
/**
* Display the specified resource.
*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function show($id)
{
//
}
/**
* Show the form for editing the specified resource.
*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function edit($id)
{
$booking = Booking::find($id);
return view('bookings.edit')->with('booking', $booking);
}
/**
* Update the specified resource in storage.
*
* #param \Illuminate\Http\Request $request
* #param int $id
* #return \Illuminate\Http\Response
*/
public function update(Request $request, $id)
{
$this->validate($request, [
'name' => 'required',
'email' => 'email',
'address' => 'required',
'phone' => 'required',
]);
$booking = Booking::find($id);
$booking->name = $request->input('name');
$booking->email = $request->input('email');
$booking->address = $request->input('address');
$booking->phone = $request->input('phone');
$booking->market_id = $request->input('market_id');
$booking->stall_id = $request->input('stall_id');
$booking->itemtype = $request->input('itemtype');
$booking->clothesrail = $request->input('clothesrail');
$booking->businessname = $request->input('businessname');
$booking->insurance = $request->input('insurance');
//Check if the user is logged in. If so then submit the user_id
if (Auth::check())
{
$booking->user_id = auth()->user()->id;
}
$booking->save();
return redirect('/admin/dashboard')->with('success', 'Booking Updated');
}
/**
* Remove the specified resource from storage.
*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function destroy($id)
{
$booking = Booking::find($id);
$booking->delete();
return redirect('/admin/dashboard')->with('success', 'Booking Removed');
}
}
My View with the form:-

NOTES:
The submit button calls the "store" method in the controller
I can't get the Stall Price to pull from the user's selection into the variable but I'll deal with that later as I can fix that, i'm just working with a fixed value variable to get it working.

Answer 1

Just change:
$stallPrice = Stall::pluck('cost')->where('id', '=', $booking->stall_id);
TO
$stallPrice = DB::table('your_stall_table')->find($booking->stall_id)->cost;
Here, you need to your_stall_table with your actual stall table name.
