获取当前控制器joomla

Question

I am developping a site in joomla 3.2, i have the same research bar in multiples views with some minor changes, so i created it in an independent php file and i'm using it in different pages . What i want to do is to change some minor informations depending on which controller is currently active I tried $_SERVER['REQUEST_URI'] it works fine but it seems a little messy here is my code

function startsWith($haystack, $needle) {
echo $needle;
echo $haystack;
return $needle === "" || strpos($haystack, $needle) === 0;
}

then i test like this

<?php if (startsWith($_SERVER['REQUEST_URI'], "/Immo/administrator/index.php?           option=com_xxo&controller=yy")) { show something ...}

is there a better way to know what controller is active for the current page ? I did not find something similar in the joomla doc

Answer 1

JFactory::getApplication()->input->get('controller'); As simple as that

Answer 2

For me, JFactory::getApplication()->input->get('controller') returns nothing. This is how I do it:

$controller = \JControllerLegacy::getInstance('whatever');

As per fabulous Joomla architecture, you cannot omit getInstance parameter although it is ignored because singleton controller instance is returned.
