I've spent hours looking for any documentation on using calculated fields, and I cannot find any! Could someone please point me in the right direction, or if there isn't give a brief primer (I won't need much, just how to get started).

I was expecting something like this.

field.ini

Code: Select all

[CALCFIELD]
widget:type = calc
widget:name = mycalcfield


atable.php

Code: Select all

class tables_mytable ...

function field_CALCFIELD(&$record) {
return 'the calculated value';
}



Where did I go wrong?

Your second attempt is close:

Code: Select all

function field__calcfield($record){
    return 'calculated value';
}


Then you can use the field programmatically:

Code: Select all

$record->val('calcfield');


Wow, that shows something about the code quality when you can guess at a function name and get that close.
Very good system.
