common object zend framework for Zend_Filter_StripTags which can be used throughout the application? - zend-framework

Question

I'm trying to create a function in bootstrap to intitiate object for Zend_Filter_StripTags, so that I can use its object throughout the application.
protected function _initHtmlFilter() {
$allowedTags = array('p','b','br','strong'); // Allowed tags
$allowedAttributes = array('href'); // Allowed attributes
$stripTags = new Zend_Filter_StripTags($allowedTags,$allowedAttributes);
}
but I'm unable to use this object($stripTags) in any controller.

Answer 1

I would create an Controller Action Helper for this:
class My_Controller_Action_Helper_StripTags extends
Zend_Controller_Action_Helper_Abstract
{
/**
* StripTags
*
* #param string $input String to strip tags from
*
* #return string String without tags
*/
public function stripTags($input)
{
$allowedTags = array('p','b','br','strong'); // Allowed tags
$allowedAttributes = array('href'); // Allowed attributes
$stripTags = new Zend_Filter_StripTags($allowedTags,$allowedAttributes);
// return input without tags
return $stripTags->filter($input);
}
}
// example in indexAction
$noTags = $this->_helper->stripTags('<h2>TEST</h2>');
You have to add the path to your helpers in your application.ini:
resources.frontController.actionhelperpaths.My_Controller_Action_Helper_ = "My/Controller/Action/Helper"

You can use zend registry for this:
protected function _initHtmlFilter() {
$allowedTags = array('p','b','br','strong'); // Allowed tags
$allowedAttributes = array('href'); // Allowed attributes
$stripTags = new Zend_Filter_StripTags($allowedTags,$allowedAttributes);
Zend_Registry::set('zend_strip_tags', $stripTags);
}
and can access it any where like :
Zend_Registry::get('zend_strip_tags');
