Yeah...I know a way...What you do is create the event in JEVENTS first. The set it all up in DTRegister. Then pull up the link that DT Register creates for you.
Here is a sample to a site I am building...
1) JEVENTS
2) DT REGISTER SETUP
3) Open Event (see example Here)
inbta.org.onlinedata.ca/index.php/business-mainmenu-29
NOTE: Make sure you create a link TO THIS.
4) Click on one of the events, it will take you to the start of the Registration tp pay.
5) YOU WILL USE PART OF THIS LINK. Here is my sample:
http://inbta.org.onlinedata.ca/index.ph ... ay_options
BUT.. NOW LISTEN UP. You only need to use everything from the word index on. like this\"index.php/business-mainmenu-29?eventId=1&task=pay_options
\" THIS is what you will attach to your button for THAT event...Joomla will take care of the rest
6) Here is my example as I linked it in the JEVENTS details to show you how it all comes together.
http://inbta.org.onlinedata.ca/index.ph ... &catids=42
7) I am a little tired..so I hope this makes sense!
