This is a strange one, but I need to call a session variable in a query.. this is actually easy enough EXCEPT there is a chance that I need to regenerate that variable (using a function) before the model is called (i,e if someone visits a certain page out of order.. such as boomarked)

At what point can I call a function called (for example) getDistanceVariable and make sure it is fired BEFORE the model is rendered for the display

Does it go in the controller somewhere, in the VIEW.HTML.PHP file etc

Thanks in advance for any assistance

You can fork your displayDefault function in VIEW.HTML.PHP.

The generated function starts with:
A couple of lines below there is
Between those lines add something like (assuming getDistanceVariable returns and int)
