- Mpdf
- Tcpdf
- WkHtmlToPdf RECOMMENDED ENGINE
Requirements
- PHP 5.4.16+
- CakePHP 3.0+
- One of the following render engines: DomPdf, Mpdf, Tcpdf or wkhtmltopdf
- pdftk (optional) See: http://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/
Installation
You can install this plugin into your CakePHP application using
composer. For existing applications you can add the
following to your composer.json
file:
And run php composer.phar update
, or composer update
(Depending on your composer setup)
CakePdf does not include any of the supported PDF engines, you need to install them yourself. The recommend wkhtmltopdf engine can be downloaded from http://wkhtmltopdf.org/, by default CakePdf expects the wkhtmltopdf binary to be located in /usr/bin/wkhtmltopdf.
DomPdf, Mpdf and Tcpdf can be installed via composer using on of the following commands:
Setup
In config/bootstrap.php
add:
Configuration
Use Configure::write('CakePdf', $config);
or set Controller property $pdfConfig
(only when used with PdfView)
You need to define at least $config['engine']
. When using CakePdf directly you can also pass the config array to constructor.
The value for engine should have the Plugin.ClassName
format without the Engine suffix
Configuration options:
- engine: Engine to be used (required), or an array of engine config options
- className: Engine class to use
- binary: Binary file to use (Only for wkhtmltopdf)
- options: Options to pass on to wkhtmltopdf
- crypto: Crypto engine to be used, or an array of crypto config options
- className: Crypto class to use
- binary: Binary file to use
- pageSize: Change the default size, defaults to A4
- orientation: Change the default orientation, defaults to potrait
- margin: Array or margins with the keys: bottom, left, right, top and their values
- title: Title of the document
- encoding: Change the encoding, defaults to UTF-8
- download: Set to true to force a download, only when using PdfView
- filename: Filename for the document when using forced download
Example:
The engine
and crypto
config options can also be arrays with configuration options for the relevant class. For example,
Usage
You can use CakePdf in 2 ways, read carefully which one you actually need. Many people mix both ways and don't get the expected results.
1: Render as PDF (including forced download) in the browser with PdfView
You can create PDF view and layout files for your controller actions and have them automatically rendered.
Place the view templates in a 'pdf' subdir, for instance src/Template/Invoices/pdf/view.ctp
Layouts will be in src/Template/Layouts/pdf/default.ctp
Make sure your InvoicesController has RequestHandler Component in the $components
array.
Browse to http://localhost/invoices/view/1.pdf
Additionally you can map resources by adding Router::mapResources(array('Invoices'));
to your routes
file and you can access the same document at http://localhost/invoices/1.pdf
2: Create PDF for email attachment, file storage etc.
You can use CakePdf lib to create raw PDF data with a view template.
The view file path would look like src/Template/Pdf/newsletter.ctp
.
Layout file path would be like src/Template/Layouts/pdf/default.ctp
Note that layouts for both usage types are within same directory, but the view templates use different file paths
Optionally you can also write the raw data to file.
Example:
Encryption
You can optionally encrypt the PDF with permissions
To use encryption you first need to select a crypto engine. Currently we support the following crypto engines:
- Pdftk
Usage
Add the following in your bootstrap.
Options in pdfConfig:
- protect: Set to true to enable encryption
- userPassword (optional): Set a password to open the PDF file
- ownerPassword (optional): Set the password to unlock the locked permissions
- one of the above must be present, either userPassword or ownerPassword
- permissions (optional): Define the permissions
Permissions:
By default, we deny all permissions.
To allow all permissions:
Set 'permission' to true
To allow specific permissions:
Set 'permissions' to an array with a combination of the following available permissions:
- degraded_print
- modify,
- assembly,
- copy_contents,
- screen_readers,
- annotate,
- fill_in
Note about static assets
Use absolute URLs for static assets in your view templates for PDFs.
If you use HtmlHelper::image()
, HtmlHelper::script()
or HtmlHelper::css()
make sure you have $options['fullBase'] = true
Another solution would be to create a AppHelper
of which it would force $options['fullBase'] = true
for PDF requests. e.g:
