Expanding the links facility
Sorry, have only just had time to get back to this.
I tried to use the FCK links facility in WA_iRite/editor/filemanager/connectors/php/config.php but gave up - maybe because there is some WA_iRite code that made it work differently.
I was puzzled why PowerCMS set up separate WA_Global links to the images and swf facilities but not to the files and media facilities provided in FCK Editor. In particular I couldn't understand why the files facility was overlooked as the link button in the editor opens that folder.
After several unsuccessful attempts to set the FCK file links correctly, I decided that the easiest way was to convert the files links in config.php to $WAGLOBAL_Files_Folder and the media links to $WAGLOBAL_Media_Folder and to add these features to the WA_Global/WA_Global.php file.
My version of the Folder part myWA_Global.php file is now:
$WAGLOBAL_Files_Folder = "../"; //relative path to your files folder.
$WAGLOBAL_Images_Folder = "../images/"; //relative path to your images folder.
$WAGLOBAL_Swf_Folder = "../swf/";//relative path to your swf folder.
$WAGLOBAL_Files_Folder = "../media/"; //relative path to your files folder.
The files folder link goes the root, the images to /images etc etc.
