I'm having major problems with this. Basically, I need to add a "url" field to the event management plugin with wordpress. My client wants to be able to add a url to their event so it can be clicked and viewed for more information on the event. I've looked through everything and im having problems understanding the wordpress file structure. I tried to add my own field to the event editor, database and front end but i dont know where wordpress posts the data to so i cant receive the variable. If i could get the variable, i could probably figure out how to use $wpdb relatively simply. but for that matter, i dont know where i should use that. where is the file that makes all those calls? i shouldnt have a problem getting the data from the database.
Edit
My problem, as described, was solved by installing another plugin called PODS. the only solution to adding functionality to a plugin, as in other fields, is to write your own plugin (as far as im aware). PODS solved my problem. It allowed me to add another field to the front of the event management form and saved it to the database. I still had to retrieve it from the database and display it on the front myself with php, but it was a much easier task than i expected it to be. If anybody wants to add extra fields to a plugin in wordpress, PODS is what i'd suggest. It's also free.
