You definitely cannot put empty() around the whole series of expressions. When
you used the && as
"and" then you will get TRUE or FALSE which is never empty.
You may want to look at isset() for your $_POST values to determine if a value
has been placed in
that variable. If you don't you will likely generate notices and warnings when
the variables have
not been set.
I would probably use:
if (! (isset($_POST['phhome']) and isset($_POST['phcell']) and
isset($_POST['phwork']) and isset($_POST['email'])))
{
...
}
If you need to check that the values are set and have a value then you might
use a custom function
to check both isset() and !empty() or something similar. One possibility is:
if (! ((isset($_POST['phhome']) and $_POST['phhome']) and
(isset($_POST['phcell']) and $_POST['phcell']) and
(isset($_POST['phwork']) and $_POST['phwork']) and
(isset($_POST['email']) and $_POST['email'])
))
{
...
}
The above doesn't appeal to me because it is extra wordy (easy to make a
mistake) and you don't
have a clear idea of which value is missing. I would probably loop through the
"required" fields
and keep track of ones which don't come up to standards.
