how to integrate htmlpurifier with symfony2? - class

Question

I am trying to integrate htmlpurifier into a symfony2 controller, but symfony2 assumes the class I am trying to instantiate is part of that vary controller, but it is not, it is an included class type frmo the htmlpurifier library.
Is there a way to escape the class name so that symfony2 doesn't look for it in the current namespace?

Answer 1

I suggest to use the bundle version of HTMLPurifier for symfony2
you can found it on gitHub : https://github.com/Exercise/HTMLPurifierBundle
it's pretty easy to install with composer
Require the bundle in your composer.json file:
{
"require": {
"exercise/htmlpurifier-bundle": "*",
}
}
Install the bundle:
$ composer update exercise/htmlpurifier-bundle
Register the bundle app/AppKernel.php :
public function registerBundles()
{
return array(
new Exercise\HTMLPurifierBundle\ExerciseHTMLPurifierBundle(),
// ...
);
}
you can use it as a service in a controller :
$purifier = $this->container->get('exercise_html_purifier.default');
$clean_html = $purifier->purify($dirty_html);
or a filter in a twig template :
{{ text|purify }}
also a Form Data Transformer for the symfony2 form builder
it's all in the docs : https://github.com/Exercise/HTMLPurifierBundle

Oh, just found it.
Instead of
require_once dirname('_FILE_') . '/plugins/htmlpurifier/library/HTMLPurifier.auto.php';
$purifier = new HTMLPurifier();
I should put a leading backslash on the class name
require_once dirname('_FILE_') . '/plugins/htmlpurifier/library/HTMLPurifier.auto.php';
$purifier = new \HTMLPurifier();
