I did add the same line “namespace ValorApps\Module\EasyFileUploader\Site\Helper;” to the php code section in my joomla article, and now I get
Error: 0 – syntax error, unexpected ‘ValorApps’ (T_STRING), expecting \\ (T_NS_SEPARATOR)
Thank you Michael – that did the trick on finding JFactory library. However, now it seems the session variables in my Joomla article are not making it to EasyFileUploaderHelper.php. Most likely the namespace issue – I am a long time developer but new to Joomla, done some php but new to namespace issue – what would I do with the Joomla article php code so they are using the same session variables?
