This package is a ServiceProvider for Snappy: [https://github.com/KnpLabs/snappy](https://github.com/KnpLabs/snappy).
### Wkhtmltopdf Installation
Choose one of the following options to install wkhtmltopdf/wkhtmltoimage.
1. Download wkhtmltopdf from [here](http://wkhtmltopdf.org/downloads.html);
2. Or install as a composer dependency. See [wkhtmltopdf binary as composer dependencies](https://github.com/KnpLabs/snappy#wkhtmltopdf-binary-as-composer-dependencies) for more information.
#### Attention! Please note that some dependencies (libXrender for example) may not be present on your system and may require manual installation.
### Testing the wkhtmltopdf installation
After installing you should be able to run wkhtmltopdf from the command line / shell.
If you went for the second option the binaries will be at `/vendor/h4cc/wkhtmltoimage-amd64/bin` and `/vendor/h4cc/wkhtmltopdf-amd64/bin`.
#### Attention vagrant users!
Move the binaries to a path that is not in a synced folder, for example:
```bash
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:
```bash
chmod +x /usr/local/bin/wkhtmltoimage-amd64
chmod +x /usr/local/bin/wkhtmltopdf-amd64
```
This will prevent the error 126.
### Package Installation
Require this package in your composer.json and update composer.
```bash
composer require barryvdh/laravel-snappy
```
### Laravel
**Laravel 5.5** uses Package Auto-Discovery, so doesn't require you to manually add the ServiceProvider/Facade. If you also use laravel-dompdf, watch out for conflicts. It could be better to manually register the Facade.
After updating composer, add the ServiceProvider to the providers array in config/app.php
```php
Barryvdh\Snappy\ServiceProvider::class,
```
Optionally you can use the Facade for shorter code. Add this to your facades:
```php
'PDF' => Barryvdh\Snappy\Facades\SnappyPdf::class,
'SnappyImage' => Barryvdh\Snappy\Facades\SnappyImage::class,
```
Finally you can publish the config file:
```bash
php artisan vendor:publish --provider="Barryvdh\Snappy\ServiceProvider"
```
### Snappy config file
The main change to this config file (config/snappy.php) will be the path to the binaries.
For example, when loaded with composer, the line should look like:
```php
'binary' => base_path('vendor/h4cc/wkhtmltopdf-amd64/bin/wkhtmltopdf-amd64'),
```
If you followed the vagrant steps, the line should look like:
```php
'binary' => '/usr/local/bin/wkhtmltopdf-amd64',
```
For windows users you'll have to add double quotes to the bin path for wkhtmltopdf:
```php
'binary' => '"C:\Program Files\wkhtmltopdf\bin\wkhtmltopdf"'
```
### Lumen
In `bootstrap/app.php` add:
```php
class_alias('Barryvdh\Snappy\Facades\SnappyPdf', 'PDF');
$app->register(Barryvdh\Snappy\LumenServiceProvider::class);
```
Optionally, add the facades like so:
```php
class_alias(Barryvdh\Snappy\Facades\SnappyPdf::class, 'PDF');
class_alias(Barryvdh\Snappy\Facades\SnappyImage::class, 'SnappyImage');
```
To customise the configuration file, copy the file `/vendor/barryvdh/laravel-snappy/config/snappy.php` to the `/config` folder.
### Usage
You can create a new Snappy PDF/Image instance and load a HTML string, file or view name. You can save it to a file, or inline (show in browser) or download.
Using the App container:
```php
$snappy = App::make('snappy.pdf');
//To file
$html = '<h1>Bill</h1><p>You owe me money, dude.</p>';
$snappy->generateFromHtml($html, '/tmp/bill-123.pdf');
$snappy->generate('http://www.github.com', '/tmp/github.pdf');
//Or output:
return new Response(
$snappy->getOutputFromHtml($html),
200,
array(
'Content-Type' => 'application/pdf',
'Content-Disposition' => 'attachment; filename="file.pdf"'
)
);
```
Using the wrapper:
```php
$pdf = App::make('snappy.pdf.wrapper');
$pdf->loadHTML('<h1>Test</h1>');
return $pdf->inline();
```
Or use the facade:
```php
$pdf = PDF::loadView('pdf.invoice', $data);
return $pdf->download('invoice.pdf');
```
You can chain the methods:
```php
return PDF::loadFile('http://www.github.com')->inline('github.pdf');
```
You can change the orientation and paper size
```php
PDF::loadHTML($html)->setPaper('a4')->setOrientation('landscape')->setOption('margin-bottom', 0)->save('myfile.pdf')
```
If you need the output as a string, you can get the rendered PDF with the output() function, so you can save/output it yourself.
See the [wkhtmltopdf manual](http://wkhtmltopdf.org/usage/wkhtmltopdf.txt) for more information/settings.
### Testing - PDF fake
As an alternative to mocking, you may use the `PDF` facade's `fake` method. When using fakes, assertions are made after the code under test is executed:
```php
<?php
namespace Tests\Feature;
use Tests\TestCase;
use PDF;
class ExampleTest extends TestCase
{
public function testPrintOrderShipping()
{
PDF::fake();
// Perform order shipping...
PDF::assertViewIs('view-pdf-order-shipping');
PDF::assertSee('Name');
}
}
```
#### Other available assertions:
```php
PDF::assertViewIs($value);
PDF::assertViewHas($key, $value = null);
PDF::assertViewHasAll(array $bindings);
PDF::assertViewMissing($key);
PDF::assertSee($value);
PDF::assertSeeText($value);
PDF::assertDontSee($value);
PDF::assertDontSeeText($value);
PDF::assertFileNameIs($value);
```
