With a good start from the folks on this list and a little JavaScript
digging, I found an excellent solution to my problem that I thought I'd share:
Problem: Want to set a cookie then test for it on the same page. I don't
want to to do page redirection to ensure optimal search engine friendliness.
Solution: Set the cookie in PHP then test for the cookie with JavaScript.
Code example below:
<?
if (! $MySession)
{
$SessionID = "2001 A Space Odyssey";
setCookie('MySession',$SessionID,time()+6048000,"/","",0);
}
?>
< h t m l > <!--html tag done that way to ensure non-HTML appearance in e-mail
<head>
<title>Test Page</title>
<SCRIPT LANGUAGE="JavaScript">
cookie_name = "MySession";
var Session;
function getSession()
{
if(document.cookie)
{
index = document.cookie.indexOf(cookie_name);
if (index != -1)
{
namestart = (document.cookie.indexOf("=", index) + 1);
nameend = document.cookie.indexOf(";", index);
if (nameend == -1)
{
nameend = document.cookie.length;
}
Session = document.cookie.substring(namestart, nameend);
return Session;
}
}
}
Session=getSession();
if (!Session)
{
CookieMessage = "Cookies are not enabled. You can browse the site, but
will need to enable them to be able make a purchase."
}
else
{
CookieMessage = ""
}
</SCRIPT>
</head>
<body>
<SCRIPT LANGUAGE="javascript">
document.write(CookieMessage);
</SCRIPT>
blah, blah, blah, the rest of the web page...
Enjoy,
