Calc field - External ("Web-ClientIP";0)

or

Text field - Autoenter - by calculation - External ("Web-ClientIP";0)

They both register the IP adress of the person creating a record, but when later changing the record, the IP adress is not registred.

According to the manual: External ("Web-ClientIP", 0) Returns the IP (Internet protocol) address of the Web user whose HTTP request is currently being processed by FileMaker Pro Web Companion.

Do I misunderstand 'HTTP request'? Is creating a new record different from altering it? Or is this another 'IWP oddity'?

(Note, that the manual says "Web-ClientIP", 0) (with a comma) and that the line in the program itself is "Web-ClientIP"; 0) (with a semi-colon). I sure hope that the comma in the manual is just a typo, not some sort of easter-egg or undocumented feature... )

Why not use CDML syntax?

Isn't he using Intuitive Web Publishing?

He is

OK.

The "Autoenter - by calculation" is just as it says and nothing else. It will autoenter value by calculation when record is created.

So no oddity here

Do I understand correctly, then, that those values, wether auto-entered or calculated, are written only upon the creation of records?

Could you explain to this newbie how I would create a field that apart from auto-enters, auto-updates the info I get from this External command?

I am thinking in the general direction of: if the value of the field changes, then create a new record somewhere (and auto-enter the IP adress).

This relational db stuff is all so new to me, it's hard to get my head around concepts that must be laughably simple for you all Let alone implementing them in FM...

Yes.

Maybe it is not possible to do it in IWP. IWP is good for simple postcard collection.

Postcard collectors have it easy. Had I only learned an honest trade when I was young...
