Hi
I have a page (page 1) which checks for the existence of a cookie. If
present a link is displayed, if not a form input box is displayed. Upon
entering an email address into the input box, access is granted to a
subsequent page (page 2). The action attribute of the form looks like this:
action="cgi-bin/formtomailscript2.cgi"
This executes the script fine when the form is submitted but the page
doesn't check for the cookie on later visits (ie it displays the input box
again rather than the link)
If the action attribute is changed to look like this:
<? echo
$_SERVER['http://www.smilelearning.com.au/cgi-bin/formtomailscript2.cgi'];
?>
Then the script is not executed, but the page successfully checks for the
cookie and displays the link on later visits, rather than the input box.
Appreciate an explanation about what's happening here and how to make sure
the script is executed and the cookie is checked.
This one really has me stumped. (Full page code below)
Thanks
David
