I'm planning to create an addon that lets the admin custom text as alert to any specific user. So the adminCP form my addon will have will be like this:- Send Alert To: [ Write Username Here ] Alert Text: [Text Box] (Send) I've been banging my head over what my actionSend should do because I really can't figure out how to trigger alerts? I've made several failed attempts at understanding the AlertHandler in XF and also xfrocks's BD Alerts Addon that has this functionality already. I think I need to understand the concept of 'Content Type' in XF; which looks like a complicated topic to me. Can someone help me understand - 1. What should my actionSend do? 2. An Algorithm (overview) for my add-on. For example: Send Button Triggers the actionSend() in my ControllerAdmin -> It then triggers the AlertHandler ->Which then gathers all the data -> Checks whether user can view alerts -> If Yes, shows the alert and then fades it away. Thank you for your time!
