Hi all, thanks for the feedback. I’ve followed Josh Morony’s formgroups and formcontrol validator’s example to do an async validator which uses a static method. I tried removing the static keyword but that simply didn’t work. What I need in the async validator is to be able to use http to check whether a username exists on a mysql table. but I can’t seem to inject the http component. the tutorial I followed is https://www.joshmorony.com/advanced-forms-validation-in-ionic-2/
Sorry if I’m using the wrong terminology anywhere. Most of this is brand new to me.
Thanks
Arthur
