PDF expansion Pack--laravel-dompdf and laravel-snappy used in Laravel

Source: Internet

The two days of the project need to convert HTML pages to PDF file for easy printing, I searched the internet a lot of information. Have tried laravel-dompdf and laravel-snappy two kinds of expansion pack, personal feeling laravel-snappy more useful.

 

First, using the Laravel-dompdf expansion pack

1. Install Expansion pack

We install it through composer.

require barryvdh/laravel-dompdf

2. Add serviceprovider to the providers array in config/app.php

Barryvdh\dompdf\serviceprovider::class, 

3. Add facade to the aliases array in config/app.php

' PDF ' = Barryvdh\dompdf\facade::class,

4. Use

You can create an dompdf instance and load an HTML string, file, or view, and then use the stream () method to display the download in the browser, save () method to a file, or download () method.

$pdf = App::make(‘dompdf.wrapper‘);

$pdf->loadHTML(‘<h1>Test</h1>‘);

return $pdf->stream();

 

You can also use the façade (facade), using the first PDF before use;

$pdf = PDF::loadView(‘pdf.invoice‘, $data);

return $pdf->download(‘invoice.pdf‘);

You can also chain-operate

return PDF::loadFile(public_path().‘/myfile.html‘)->save(‘/path-to/my_stored_file.pdf‘)->stream(‘download.pdf‘);

You can change the direction (landscape the direction to landscape, generally use vertical, pay attention when using) and paper size, and hide or show errors (by default, display errors when debugging is turned on)

Pdf::loadhtml ($html)->setpaper (' A4 ', ' Landscape ')->setwarnings (false)->save (' Myfile.pdf ')

For some other basic usage and configuration please refer to documentation https://github.com/barryvdh/laravel-dompdf

 

5, solve the problem of Chinese garbled

Download a Chinese font that supports Unicode encoding. Example: Msyh.ttf (Microsoft Ya-Black)

It is recommended to create the Fonts folder under Storage, put the font in the Fonts folder, or you will get an error.

Introducing fonts in CSS

<style>

            @font-face {

                font-family: ‘msyh‘;

                font-style: normal;

                font-weight: normal;

                src: url({{ storage_path(‘your_path/msyh.ttf‘) }}) format(‘truetype‘);

            }

            body {

                font-family: msyh, DejaVu Sans,sans-serif;

            }

</style>

 

Note: The pro-test is only Unicode-encoded in Chinese to display properly, which is why I think this PDF extension is not very useful.

 

Second, the use of Laravel-snappy expansion package

1. Install dependent software

Laravel-snappy expansion pack requires WKHTMLTOPDFF support, so install Wkhtmltopdf first

Method One: Download the Wkhtmltopdf installation package

Wkhtmltopdfhttp://www.softpedia.com/get/office-tools/pdf/wkhtmltopdf.shtml

Windows can download the installation directly, and note that installing to the place you know, this path is useful later.

My installation is under the G:WK directory

Wkhtmltoimage and wkhtmltopdf two dependent software in bin directory

When the Linux download is complete, move the file to/usr/local/bin

 

Method Two: Install by composer

Take the Linux system as an example

32-bit:

$ composer require h4cc / wkhtmltopdf-i386 0.12.x

$ composer require h4cc / wkhtmltoimage-i386 0.12.x,

64-bit:

$ composer require h4cc/wkhtmltopdf-amd64 0.12.x

$ composer require h4cc/wkhtmltoimage-amd64 0.12.x

 

(unname -a command to view system digits)

Cp vendor/h4cc/wkhtmltoimage-amd64/bin/wkhtmltoimage-amd64 /usr/local/bin/

Cp vendor/h4cc/wkhtmltopdf-amd64/bin/wkhtmltopdf-amd64 /usr/local/bin/

And make it executable:

Chmod +x /usr/local/bin/wkhtmltoimage-amd64

Chmod +x /usr/local/bin/wkhtmltopdf-amd64

 

The use of this third-party plugin under Linux requires several library support

apt-get install libXrender*

apt-get install libfontconfig*

 

1. Installing the Laravel-snappy expansion pack

Composer require barryvdh/laravel-snappy

2. Adding serviceprovider to the providers array in config/app.php

Barryvdh\snappy\serviceprovider::class,

3. Add facade to the aliases array in config/app.php

‘PDF‘ => Barryvdh\Snappy\Facades\SnappyPdf::class,

‘SnappyImage‘ => Barryvdh\Snappy\Facades\SnappyImage::class,

4. Generate Configuration file

PHP artisan vendor:publish--provider= "Barryvdh\snappy\serviceprovider"

This command generates a configuration file in the config/snappy.php


The specific configuration is as follows:

<?php

Return array(

     ‘pdf’ => array(

         ‘enabled‘ => true,

// ‘binary‘ => ‘/usr/local/bin/wkhtmltopdf’, //dependent software path, linux defaults in this directory

         ‘binary‘ => ‘G:\wk\wkhtmltopdf\bin\wkhtmltopdf’,

         ‘timeout‘ => false,

         ‘options‘ => array(),

         ‘env‘ => array(),

     ),

     ‘image’ => array(

         ‘enabled‘ => true,

// ‘binary‘ => ‘/usr/local/bin/wkhtmltoimage‘,

         ‘binary‘ => ‘G:\wk\wkhtmltopdf\bin\wkhtmltoimage’,

         ‘timeout‘ => false,

         ‘options‘ => array(),

         ‘env‘ => array(),

     ),

);


5. Use (similar to using dompdf)

First introduce

use PDF;

use SnappyImage;


Generate PDF files

You can use the façade (facade) to load an HTML string, file, or view, and then use the stream () method to display the download in the browser, save () method to a file, or download () method.

$pdf = PDF::loadView(‘pdf.invoice‘, $data);

return $pdf->download(‘invoice.pdf‘)

You can also chain-operate

return Pdf::loadfile (Public_path (). ' /myfile.html ')->save ('/path-to/my_stored_file.pdf ')->stream (' download.pdf ');


You can change the direction (landscape the direction to landscape, generally use vertical, pay attention when using) and paper size, and hide or show errors (by default, display errors when debugging is turned on)

Pdf::loadhtml ($html)->setpaper (' A4 ', ' Landscape ')->setwarnings (false)->save (' Myfile.pdf ')

 

Create a picture 

$pdf = SnappyImage::loadView(‘pdf.invoice‘, $data);

return $pdf->download(‘invoice.image‘);

 

6, solve the English garbled problem (Linux)

You can add an example: Arial or other Chinese fonts to the /usr/share/fonts/ .
