Documentation
Installation
There are couple ways to install this plugin.
- Use
php artisan plugin:install Renatio.DynamicPDF
command. - Use
composer require renatio/dynamicpdf-plugin
in project root. When you use this option you must runphp 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:
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:
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.
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:
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:
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
).
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
).
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.
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:
You can still alter the dompdf options in your code before generating the PDF using dynamic methods for all options like so:

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:
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.
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:
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.
I assume that $file
is instance of October\Rain\Database\Attach\File
.
Then in the template you can use following example code:
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.
After that you must place following code before closing </body>
tag of the layout file.
Examples
Demo examples
There is a console command that will enable demo templates and layouts.
To disable demo run following command:
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
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
Fluent interface
You can chain the methods:
Change paper size and orientation
Available paper sizes.
PDF on CMS page
To display PDF on CMS page you can use PHP section of the page like so:
Header and footer on every page
Using custom fonts
Plugin provides "Open Sans" font, which can be imported in Layout CSS section.
