[Resolved] A $_POST question again :)

[szz]

Hi again!

I want to know that if in a form a textfield is leaved blank, what is the submitted value?
Is it a '' (blank string) or it s not defined?

Thanks.

If no value submitted, the following will all evaluate to true:

is_set($_POST['myunenteredtext'])

!$_POST['myunenteredtext']

$_POST['myunenteredtext']===''

In otherwords, yes, it is returned as '' or a NULL value, not undefined.
