CB substitution issue

This is a rather minor thing, but it's still got me stumped (this kind of thing drives me nuts).

I am trying to do this: so I can display my own choice of avatar. But it doesn't seem to work.

I've also tried this with the same result. An image file called nophoto_n.png seems to show up when the database has nothing in the avatar field for a user.
Just exactly what value WILL the avatar field contain if the user hasn't selected one? What's the trick to this?

Thanks in advance.

Shouldn't be necessary to do that to have your own defaults. Edit your avatar field then under Parameters > Image Display adjust the "Pending Default" and "Empty Default" parameters as needed. Place your custom images in the below folder for them to be available in the dropdown.

/components/com_comprofiler/plugin/templates/default/images/avatar

The avatar field is never truly empty as we output the URL to the image when using raw substitutions so it'll point to the default pending or empty as needed.

Works for me as far as what to display. But what I was after was a way to find out if it was empty or not.

You'd have to IF substitution condition against nophoto. Below topic shows example of how to do this with gender based defaults.
