# Documentation
## Installation
There are couple ways to install this plugin.
1. Use `php artisan plugin:install Renatio.DynamicPDF` command.
2. Use `composer require renatio/dynamicpdf-plugin` in project root. When you use this option you must
run `php artisan october:migrate` after installation.
## PDF content
PDF can be created in October using either PDF views or PDF templates. A PDF view is supplied by plugin in the file
system in the **/views** directory. Whereas a PDF template is managed using the back-end interface via *Settings > PDF >
PDF Templates*. All PDFs templates support using Twig for markup.
PDF views must be registered in the Plugin registration file with the `registerPDFTemplates` and `registerPDFLayouts`
method. This will automatically generate a PDF template and layout and allows them to be customized using the back-end
interface.
## PDF layouts views
PDF layouts views reside in the file system and the code used represents the path to the view file. For example PDF
layout with the code **author.plugin::pdf.layouts.default** would use the content in following file:
```
plugins/ <=== Plugins directory
author/ <=== "author" segment
plugin/ <=== "plugin" segment
views/ <=== View directory
pdf/ <=== "pdf" segment
layouts/ <=== "layouts" segment
default.htm <=== "default" segment
```
The content inside a PDF view file can include up to 3 sections: **configuration**, **CSS/LESS**, and **HTML markup**.
Sections are separated with the `==` sequence. For example:
```
name = "Default PDF layout"
==
body {
font-size: 16px;
}
==
Document
{{ css|raw }}
{{ content_html|raw }}
```
> **Note:** Basic Twig tags and expressions are supported in PDF views.
The **CSS/LESS** section is optional and a view can contain only the configuration and HTML markup sections.
```
name = "Default PDF layout"
==
Document
{{ css|raw }}
{{ content_html|raw }}
```
### Configuration section
The configuration section sets the PDF view parameters. The following configuration parameters are supported:
| Parameter | Description |
|-----------|----------------------------|
| **name** | the layout name, required. |
### Using PDF layouts
PDF layouts reside in the database and can be created by selecting *Settings > PDF > PDF Templates* and clicking the *
Layouts* tab. These behave just like CMS layouts, they contain the scaffold for the PDF. PDF views and templates support
the use of PDF layouts. The **code** specified in the layout is a unique identifier and cannot be changed once created.
## PDF templates views
PDF templates reside in the file system and the code used represents the path to the view file. For example PDF template
with the code **author.plugin::pdf.invoice** would use the content in following file:
```
plugins/ <=== Plugins directory
author/ <=== "author" segment
plugin/ <=== "plugin" segment
views/ <=== View directory
pdf/ <=== "pdf" segment
invoice.htm <=== "invoice" segment
```
The content inside a PDF view file can include up to 2 sections: **configuration** and **HTML markup**. Sections are
separated with the `==` sequence. For example:
```
title = "Invoice"
layout = "renatio.demo::pdf.layouts.default"
description = "Invoice template"
size = "a4"
orientation = "portrait"
==
Invoice
```
> **Note:** Basic Twig tags and expressions are supported in PDF views.
### Configuration section
The configuration section sets the PDF view parameters. The following configuration parameters are supported:
| Parameter | Description |
|-----------------|---------------------------------------------------------------|
| **title** | the template title, required. |
| **layout** | the layout code, optional. |
| **description** | the template description, optional. |
| **size** | the template paper size, optional, default `a4`. |
| **orientation** | the template paper orientation, optional, default `portrait`. |
### Using PDF templates
PDF templates reside in the database and can be created in the back-end area via *Settings > PDF > PDF Templates*.
The **code** specified in the template is a unique identifier and cannot be changed once created.
> **Note:** If the PDF template does not exist in the system, this code will attempt to find a PDF view with the same
> code.
## Registering PDF templates and layouts
PDF views can be registered as templates that are automatically generated in the back-end ready for customization. PDF
templates can be customized via the *Settings > PDF Templates* menu. The templates can be registered by adding
the `registerPDFTemplates` method of the Plugin registration class (`Plugin.php`).
```
public function registerPDFTemplates()
{
return [
'renatio.demo::pdf.invoice',
'renatio.demo::pdf.resume',
];
}
```
The method should return an array of pdf view names.
Like templates, PDF layouts can be registered by adding the `registerPDFLayouts` method of the Plugin registration
class (`Plugin.php`).
```
public function registerPDFLayouts()
{
return [
'renatio.demo::pdf.layouts.invoice',
'renatio.demo::pdf.layouts.resume',
];
}
```
The method should return an array of pdf view names.
## Usage
PDF templates and layouts can be accessed in the back-end area via *Settings > PDF > PDF Templates*.
Layouts define the PDF scaffold, that is everything that repeats on a PDF, such as a header and footer. Each layout has
unique code, optional background image, HTML content and CSS/LESS content. Not all CSS properties are supported, so
check [CSSCompatibility](https://github.com/dompdf/dompdf/wiki/CSSCompatibility).
Templates define the actual PDF content parsed from HTML.
## Configuration
The default configuration settings are set in `config/dompdf.php`. Copy this file to your own config directory to modify
the values. You can publish the config using this command:
```
php artisan vendor:publish --provider="Barryvdh\DomPDF\ServiceProvider"
```
You can still alter the dompdf options in your code before generating the PDF using dynamic methods for all options like
so:
```
PDF::loadTemplate('renatio::invoice')
->setDpi(300)
->setDefaultFont('sans-serif')
->stream();
```
or you can use `setOption` method before generating the pdf using this command:
```
PDF::loadTemplate('renatio::invoice')
->setOption(['dpi' => 300, 'defaultFont' => 'sans-serif'])
->stream();
```

## Tips
### Background image
To display background image added in layout use following code:
```
```
Background image should be at least 96 DPI size (793 x 1121 px).
If you want to use better quality image like 300 DPI (2480 x 3508 px) than you need to change template options like so:
```
return PDF::loadTemplate($model->code)
->setDpi(300)
->stream();
```
### UTF-8 support
In your layout, set the UTF-8 meta tag in `head` section:
```
```
If you have problems with foreign characters than try to use **DejaVu Sans** font family.
### Page breaks
You can use the CSS page-break-before/page-break-after properties to create a new page.
```
.page-break {
page-break-after: always;
}
Page 1
Page 2
```
### Open basedir restriction error
On some hosting providers there were reports about `open_basedir` restriction problems with log file. You can change
default log file destination like so:
```
return PDF::loadTemplate('renatio::invoice')
->setLogOutputFile(storage_path('temp/log.htm'))
->stream();
```
### Embed image inside PDF template
You can use absolute path for image eg. `https://app.dev/path_to_your_image`.
For this to work you must set `isRemoteEnabled` option.
```
return PDF::loadTemplate('renatio::invoice', ['file' => $file])
->setIsRemoteEnabled(true)
->stream();
```
I assume that `$file` is instance of `October\Rain\Database\Attach\File`.
Then in the template you can use following example code:
```
{{ file.getPath }}
{{ file.getLocalPath }}
{{ file.getThumb(200, 200, {'crop' => true}) }}
```
> For retrieving stylesheets or images via http following PHP setting must be enabled `allow_url_fopen`.
When `allow_url_fopen` is disabled on server try to use relative path. You can use October `getLocalPath` function on
the file object to retrieve it.
### Download PDF via Ajax response
OctoberCMS ajax framework cannot handle this type of response.
Recommended approach is to save PDF file locally and return redirect to PDF file.
### Page numbers
Page numbers can be generated using PHP. Inline PHP is disabled by default, because it can be a security risk. You can
enable inline PHP using `setIsPhpEnabled` method.
```
return PDF::loadTemplate('renatio::invoice')
->setIsRemoteEnabled(true)
->setIsPhpEnabled(true)
->stream();
```
After that you must place following code before closing `` tag of the layout file.
```
if (isset($pdf)) {
$size = 9;
$color = [0,0,0];
$font = $fontMetrics->getFont('Open Sans');
$textHeight = $fontMetrics->getFontHeight($font, $size);
$width = $fontMetrics->getTextWidth('Page 1 of 2', $font, $size);
$foot = $pdf->open_object();
$w = $pdf->get_width();
$h = $pdf->get_height();
$y = $h - $textHeight - 13;
$pdf->close_object();
$pdf->add_object($foot, 'all');
$text = "Page {PAGE_NUM} of {PAGE_COUNT}";
// Center the text
$pdf->page_text($w / 2 - $width / 2, $y, $text, $font, $size, $color);
}
```
## Examples
### Demo examples
There is a console command that will enable demo templates and layouts.
```
php artisan dynamicpdf:demo
```
To disable demo run following command:
```
php artisan dynamicpdf:demo --disable
```
The first example shows invoice with custom font and image embed.
The second example shows usage of header & footer, page break, page numbers and full background image.
### Render PDF in browser
```
use Renatio\DynamicPDF\Classes\PDF; // import facade
public function pdf()
{
$templateCode = 'renatio::invoice'; // unique code of the template
$data = ['name' => 'John Doe']; // optional data used in template
return PDF::loadTemplate($templateCode, $data)->stream('download.pdf');
}
```
Where `$templateCode` is an unique code specified when creating the template, `$data` is optional array of twig fields
which will be replaced in template.
In HTML template you can use `{{ name }}` to output `John Doe`.
### Download PDF
```
use Renatio\DynamicPDF\Classes\PDF;
public function pdf()
{
return PDF::loadTemplate('renatio::invoice')->download('download.pdf');
}
```
### Fluent interface
You can chain the methods:
```
return PDF::loadTemplate('renatio::invoice')
->save('/path-to/my_stored_file.pdf')
->stream();
```
### Change paper size and orientation
```
return PDF::loadTemplate('renatio::invoice')
->setPaper('a4', 'landscape')
->stream();
```
Available [paper sizes](https://github.com/dompdf/dompdf/blob/master/src/Adapter/CPDF.php#L40).
### PDF on CMS page
To display PDF on CMS page you can use PHP section of the page like so:
```
use Renatio\DynamicPDF\Classes\PDF;
function onStart()
{
return PDF::loadTemplate('renatio::invoice')->stream();
}
```
### Header and footer on every page
```
@page { margin: 100px 25px; }
header { position: fixed; top: -60px; left: 0px; right: 0px; background-color: lightblue; height: 50px; }
footer { position: fixed; bottom: -60px; left: 0px; right: 0px; background-color: lightblue; height: 50px; }
p { page-break-after: always; }
p:last-child { page-break-after: never; }
header on each page
footer on each page
page1
page2
```
### Using custom fonts
Plugin provides "Open Sans" font, which can be imported in Layout CSS section.
```
@font-face {
font-family: 'Open Sans';
src: url({{ 'plugins/renatio/dynamicpdf/assets/fonts/OpenSans-Regular.ttf'|app }});
}
@font-face {
font-family: 'Open Sans';
font-weight: bold;
src: url({{ 'plugins/renatio/dynamicpdf/assets/fonts/OpenSans-Bold.ttf'|app }});
}
@font-face {
font-family: 'Open Sans';
font-style: italic;
src: url({{ 'plugins/renatio/dynamicpdf/assets/fonts/OpenSans-Italic.ttf'|app }});
}
@font-face {
font-family: 'Open Sans';
font-style: italic;
font-weight: bold;
src: url({{ 'plugins/renatio/dynamicpdf/assets/fonts/OpenSans-BoldItalic.ttf'|app }});
}
body {
font-family: 'Open Sans', sans-serif;
font-size: 16px;
}
```
