[PHP] Document Contains No Data in Netscape?
I have a set of pages I've been working on to do address entry for
registered users to a MySQL database. I'm running up against a wall that
I've been fighting for two days...
process is thus:
checks session vars to see if user is logged in. if not, present login screen.
if logged in:
see if this is a submitted form, or a blank request for one.
if blank request, present the HTML form.
if submitted:
check the incoming data to determine if the address type (home, work or
other) is set. if not, give error.
if set, checks to see if that type was already in the database for that user,
and checks to see if this address was flagged as the mailing address. if
either case, give error and exit.
past all that? The the script SHOULD run the mysql_query and insert the
submitted data to the database.
if successful, should return one of two options: either go to the site
main index page, or
reload a blank address form if the user wants to enter an additional address.
My problem is coming in AFTER the type and mailing checks, and before the
mysql_query. I can't
find any problems with the script; everything looks right to me. However:
if I fill out the form and leave out the type field, I get the correct error.
if I mark a type that exists in the database already, or that type already
has a mailing flag set, I get the correct error.
if I fill out the form correctly, and hit either button, I get a Netscape
error "Document Contains No Data".
What in tarnation is going on? Can someone help me please?

Re: [PHP] Session not destroying properly
I'm running the following to kill a session, and haven't had any problems
with it yet...
try
>session_start();
