zend 1 view helper functions use in another view helper class - php

Question

i have two helper classes
link are :
C:\xampp\htdocs\ecom\application\views\helpers\comman.php
C:\xampp\htdocs\ecom\application\views\helpers\RefineUrl.php
class Zend_View_Helper_Refinestr
{
public function Refinestr($str, $options = array()){
..............
.............
return $str;
}
}
second is
class Zend_View_Helper_Comman
{
public function Comman(){
return $this;
}
public function getPageContent($pageId){
// return $pageId;
$mapper = new Application_Model_StaticpageMapper();
$selectedFields=array('desc');
$tblName=array($mapper->getDbTable()->_name);
$whr= "`id`=$pageId";
$content=$mapper->fetchSelectedFields($tblName,$selectedFields,$whr);
$des=$content[0]['desc'];
// here i want to use function Refinestr() of another helper class how i use this
$des=$this->Refinestr($des);
// not working , searching this function inside comman class
} }
How to use one helper class function in another helper class function?

Answer 1

You can use below trick for your case.
While calling getPageContent() helper from your view file pass the view object in helper as a param (like $pageId) and use that view object to call another helper in helper definition.
View file:
<?php echo $this->getPageContent($pageId, $this); ?>
Helper File:
class Zend_View_Helper_GetPageContent {
public function getPageContent($pageId, $viewObj) {
// return $pageId;
$mapper = new Application_Model_StaticpageMapper ();
$selectedFields = array ('desc'
);
$tblName = array ($mapper->getDbTable ()->_name
);
$whr = "`id`=$pageId";
$content = $mapper->fetchSelectedFields ( $tblName, $selectedFields, $whr );
$des = $content [0] ['desc'];
// here i want to use function Refinestr() of another helper class how i
// use this
$des = $viewObj->Refinestr($des); //use view object to call another helper
}
}
Another helper will remain as it is.
One more solution to this problem could be, set view object in Zend Registry at the time of bootstrapping and use that registry variable in helper file to call another helper.
In Bootstrap File:
protected function _initConfig() {
$this->bootstrap('view');
$this->_view = $this->getResource('view');
Zend_Registry::set('viewObj', $this->_view);
}
Helper File:
class Zend_View_Helper_GetPageContent {
public function getPageContent($pageId) {
// return $pageId;
$mapper = new Application_Model_StaticpageMapper ();
$selectedFields = array ('desc');
$tblName = array ($mapper->getDbTable ()->_name);
$whr = "`id`=$pageId";
$content = $mapper->fetchSelectedFields ( $tblName, $selectedFields, $whr );
$des = $content [0] ['desc'];
// here i want to use function Refinestr() of another helper class how i
// use this
$viewObj = Zend_Registry::get('viewObj');
$des = $viewObj->Refinestr($des); //use view object to call another helper
}
}

I usually do the following:
Inside helper1
$this->helper1()->view->helper2();
In case helper1 is taking some arguments, I modify it to take no arguments and just return. Try it out, may work.
