Joomla documentation says
Joomla has an additional parameter called extra_query in the #__update_sites table. This parameter will be added to the declared download URL
However when I add ids = kjlsdlkfiuewr87ifdtuyr8237 into the extras field in the update sites table it is not passed as part of $_GET.
Do I need to do something besides add it to the extras column in the table - add code somewhere?
