Joomla 2.5 can not use $ this in the helper file
I have created a component and a plugin in joomla 2.5 and there is a Helper
file in the component which will have many useful functions and I plan to call one of its function which then calls another function in the helper by this code:
$this->getinformation();
and it gives me this error :
Fatal error: Call to undefined method
My questions are:
- Why can't I call a function in a helper in Joomla?
- How can I call a function inside helper class?
- Is there any class structure which i missed in this code?
Helper files are typically called statically and not using $this
First create your helper file and add methods like this:
Class myHelper {
//This method can call other methods
public static function myMethod($var) {
//Call other method inside this class like this:
self:myOtherMethod($var);
}
//This method is called by myMethod()
public static function myOtherMethod($var) {
//Put some code here
}
}
Simply include the helper file like this in the documents that you would to use it:
require_once JPATH_COMPONENT.'/helpers/my_helper.php';
Then use it like this:
myHelper::myMethod($var);
myHelper::myOtherMethod($var);
