Still Not working
I created a module using the instructions on this forum to link to the Easy PHP Calendar which is called Event Calendar. It shows up as it is supposed to in the module block on the home page of my site. When you click on the tag it takes you to the event calendar page.
To try to make the filtering plugin work, it was recommended that I try the $thisFile function. I added:
before the call to the filter plugin in the index.php file in my Event Calendar module.
Now if you use the fliter, the system returns the screen back to my website's home page, and filters the events that show in the calendar block on the home page in accordance with the filter that was set.
