OMG, this one just came to mind and I guess it's mainly for 'dummies' like me (i.e. real entry level Cook users LOL).

A new Data Type (or Wizard): Simple Calculation. Allowing as a start 2 existing Fields to be selected AND an Operand (i.e. Addition, Subtraction, Multiplication, Divide).

So that a beginner can include simple math calculations in their Layouts.

i.e.

Value 1: Field number_of_days (int)
Value 2: Field amount (int xx.xx)
Operand: MULTIPLY
Simple Calculation Field: Result (Value 1 multiplied by Value 2)

I think that might put the idea across. Please ask if unclear.

To me this would be a fantastic addition.

Thank you,

Edward.

So easy to add in code afterwards, but why not have a wizard for it...

Well you simply use the math operators of php...
$a + $b or things like that

I think that better coders than me would have to answer this, but i don't think there's any need in storing the result of two db fields in a third field...
Anyway, if you want this, i think you have to add a field to your table manually via phpmyadmin, then modify the model file, or the corresponding table field in the administrator part of your component.
That's my 2 cents, but i believe Admin will have a more definitive approach on this.

@VeCrea,

Your solution is incorrect.
JDom return strings, so it is not only incorrect but also dangerous.


Why always searching for complexity ?
echo $this->climatpraticitem->year + $this->otherfield->year;

... And if you want this result stored in DB, go in your table and write this operation before to save in table.

1. open the concerned table php file

2. go to the check() function.
(Executed everytime before to save)

3. Write all the new values coming from the result of your calcul

That's it

PS : As you know, I prefer you try to find by yourself, and understand how the MVC works.

Freakin' Awesome!!! J-Cook is simply awesome - whether you're a highly experienced developer or complete novice whether you're building a small inventory component or a complete community solution! The beauty comes from a fast slick and reliable platform that readily provides developers with everything they'll need to build the backbone of a solid and secure component with wizards for authoring access publishing aliasing created/modified by dates... you name it COOK provides it! J-Cook really surpasses all of the 'competition' as far as MVC tools are concerned! Try love it and get cooking!
