Ever needed to merge multiple PDF's together? It's a common need. In this tutorial, I'll cover how to do merge multiple pdf's together in Laravel.
First, we need a package called lara-pdf-merger Install it with composer:
composer require daltcore/lara-pdf-merger
Next, create import the namespace:
use LynX39\LaraPdfMerger\Facades\PdfMerger;
Create a new instance:
$pdfMerger = PDFMerger::init();
Add PDF to be merged:
$pdfMerger->addPDF(base_path('Modules/Quotes/pages/1.pdf'), 'all');
Do this for each PDF to be merged.
$pdfMerger->addPDF(base_path('Modules/Quotes/pages/1.pdf'), 'all');
$pdfMerger->addPDF(base_path('Modules/Quotes/pages/2.pdf'), 'all');
$pdfMerger->addPDF(base_path('Modules/Quotes/pages/3.pdf'), 'all');
$pdfMerger->addPDF(base_path('Modules/Quotes/pages/4.pdf'), 'all');
Next, call a merge method to perform the merge.
$pdfMerger->merge();
Next, save the PDF to disk
$pdfMerger->save(public_path('quotes/001.pdf'), "file");
Putting this all together:
$pdfMerger = PDFMerger::init(); //Initialize the merger
$pdfMerger->addPDF(base_path('Modules/Quotes/pages/1.pdf'), 'all');
$pdfMerger->addPDF(base_path('Modules/Quotes/pages/2.pdf'), 'all');
$pdfMerger->addPDF(base_path('Modules/Quotes/pages/3.pdf'), 'all');
$pdfMerger->addPDF(base_path('Modules/Quotes/pages/4.pdf'), 'all');
$pdfMerger->merge();
$pdfMerger->save(public_path('quotes/001.pdf'), "file");
Generate a PDF and merge with existing
You may want to generate new PDF and merge that in with existing PDFs.
Let's install Laravel DOMPDF to make a new PDF. Install with composer:
composer require barryvdh/laravel-dompdf
Import PDF:
use PDF;
Create a new PDF, load a view file (quotes/pdf.blade.php) for the contents of the PDF and save to a quotes folder and use the filename quote-001.pdf
$filename = "quote-001.pdf";
$pdf = PDF::loadView('quotes.pdf', ['quote' => $data]);
$pdf->save('quotes/'.$filename);
Now, this can be merged using the same technique above.
$filename = "quote-001.pdf";
$pdf = PDF::loadView('quotes/pdf', ['quote' => $record]);
$pdf->save('quotes/'.$filename);
$pdfMerger = PDFMerger::init(); //Initialize the merger
$pdfMerger->addPDF(base_path('Modules/Quotes/pages/1.pdf'), 'all');
$pdfMerger->addPDF(base_path('Modules/Quotes/pages/2.pdf'), 'all');
$pdfMerger->addPDF(base_path('Modules/Quotes/pages/3.pdf'), 'all');
$pdfMerger->addPDF(base_path('Modules/Quotes/pages/4.pdf'), 'all');
$pdfMerger->addPDF(public_path('quotes/'.$filename), 'all');
$pdfMerger->addPDF(base_path('Modules/Quotes/pages/5.pdf'), 'all');
$pdfMerger->merge();
$pdfMerger->save(public_path('quotes/quote-001.pdf'), "file");
