php Laravel打印纸

Question

My website is related to flight tickets, after booking the ticket and ticket gets issued if i want to print the ticket, it is showing the paths of the buttons in agent panel like this -> welcome agent, Profile ( http://localhost/tb/customer/dashboard ) MarkUp ( http://localhost/tb/agent/markup/list ) Dashboard (localhost/tb) reports (localhost/tb/list)

View Ticket Details after all these, ticket details are printing.

Answer 1

I like DocRaptor for this kind of thing. Send an API request with some HTML/CSS/Javascript and you get back a PDF with which you can do anything you want, including presenting to the user for download/printing.

They even provide a PHP class to handle API access.

It's a pay service, but it is worth every penny.

Generating a PDF locally has never worked well for me. Between the formatting problems that arise with different libraries, lack of Javascript support, and the resources consumed by the process, it was just too inconvenient.

If you want to create PDF and then print the view, try this PDF generation plugin such as pdf-laravel . This is just a DOMPDF module for Laravel 5.

To get this pdf-laravel5 plugin, run below composer command :

composer require vsmoraes/laravel-pdf

To add provider, update config/app.php with below line to providers array :

'PDF' => 'Vsmoraes\Pdf\PdfFacade',

To generate out file:

$router->get('/pdf/output', function() { 
    $html = view('pdfs.example')->render();

    PDF::load($html)
        ->filename('/tmp/example1.pdf')
        ->output();

    return 'PDF saved';

});

Inject on your controller:

<?php namespace App\Http\Controllers;

use Vsmoraes\Pdf\Pdf;

class HomeController extends BaseControler
{
    private $pdf;

    public function __construct(Pdf $pdf)
    {
        $this->pdf = $pdf;
    }

    public function helloWorld()
    {
        $html = view('pdfs.example1')->render();

        return $this->pdf
            ->load($html)
            ->show();
    }
}

You can also force to download PDF like:

$router->get('/pdf/download', function() {
    $html = view('pdfs.example')->render();

    return PDF::load($html)->download();
});
