Hey guys,

I am getting there working with cook.

This is a form on the back end of my component:

I would like to automatically fill the reference text field at the top using the PHP TIME() function. I.e. when I click 'New' on the collections side of my backend I want the reference text field to automatically be filled with the TIME() function.

I also want to make the pending amount field automatically fill with Total Amount - Amount Paid.

I'm sure that I have to change a few files of my component but I'm unsure of where to look.

Thanks for your help.

You must fork the model of the concerned table.
Have a look in loadFormData()
