Invoice Generator Laravel Project Guide, Code Structure, and Examples
Laravel is a popular PHP web framework used for building robust and scalable web applications. In this guide, we will explore how to create an invoice generator Laravel project, including the code structure and examples.
Project Overview
The invoice generator project will allow users to create and manage invoices for their customers. It will include features such as creating new invoices, editing existing invoices, and generating PDF invoices.
Project Structure
The project structure for the invoice generator will include the following folders and files:
app/Models: Contains the Invoice modelapp/Controllers: Contains the InvoiceControllerapp/Views: Contains the views for the invoicesroutes/web.php: Contains the routes for the invoices
Database Schema
The database schema for the invoice generator will include the following tables:
| id |
customer_id |
invoice_date |

Invoice Model
The Invoice model will be responsible for interacting with the database and retrieving the invoice data.
namespace AppModels;
use IlluminateDatabaseEloquentModel;
class Invoice extends Model
{
protected $fillable = ['customer_id', 'invoice_date', 'due_date', 'subtotal', 'tax', 'total'];
}
Invoice Controller
The Invoice controller will be responsible for handling the CRUD operations for the invoices.
namespace AppHttpControllers;
use IlluminateHttpRequest;
use AppModelsInvoice;
class InvoiceController extends Controller
{
public function index()
{
$invoices = Invoice::all();
return view('invoices.index', compact('invoices'));
}
public function create()
{
return view('invoices.create');
}
public function store(Request $request)
{
$invoice = new Invoice();
$invoice->customer_id = $request->input('customer_id');
$invoice->invoice_date = $request->input('invoice_date');
$invoice->due_date = $request->input('due_date');
$invoice->subtotal = $request->input('subtotal');
$invoice->tax = $request->input('tax');
$invoice->total = $request->input('total');
$invoice->save();
return redirect()->route('invoices.index');
}
public function edit($id)
{
$invoice = Invoice::find($id);
return view('invoices.edit', compact('invoice'));
}
public function update(Request $request, $id)
{
$invoice = Invoice::find($id);
$invoice->customer_id = $request->input('customer_id');
$invoice->invoice_date = $request->input('invoice_date');
$invoice->due_date = $request->input('due_date');
$invoice->subtotal = $request->input('subtotal');
$invoice->tax = $request->input('tax');
$invoice->total = $request->input('total');
$invoice->save();
return redirect()->route('invoices.index');
}
public function destroy($id)
{
$invoice = Invoice::find($id);
$invoice->delete();
return redirect()->route('invoices.index');
}
}
Views
The views for the invoices will include the following files:
invoices/index.blade.php: Displays a list of all invoicesinvoices/create.blade.php: Displays a form to create a new invoiceinvoices/edit.blade.php: Displays a form to edit an existing invoice
Routes
The routes for the invoices will include the following routes:
GET /invoices: Displays a list of all invoicesGET /invoices/create: Displays a form to create a new invoicePOST /invoices: Creates a new invoiceGET /invoices/{id}/edit: Displays a form to edit an existing invoicePUT /invoices/{id}: Updates an existing invoiceDELETE /invoices/{id}: Deletes an existing invoice
PDF Invoices
The PDF invoices will be generated using the RentInvoice library.
namespace AppHttpControllers;
use IlluminateHttpRequest;
use AppModelsInvoice;
use RentInvoiceInvoiceGenerator;
class InvoiceController extends Controller
{
public function generatePdf($id)
{
$invoice = Invoice::find($id);
$generator = new InvoiceGenerator();
$pdf = $generator->generatePdf($invoice);
return response($pdf, 200)->header('Content-Type', 'application/pdf');
}
}
