what i need is, when component run,component change content of position.
for example when url is: index.php?option=com_test , content of position 'left' = test
and when url is: index.php?option=com_users, position show default data by modules.
i want tp change content of modules in this position too.
i have viewed https://joomla.stackexchange.com/questions/1054/displaying-a-joomla-module-using-php but this is for view module in component.
