I’m not great at PHP, and everything I currently know, I have just taught myself by browsing the internet.
I am currently trying to work with cookies in my page, in order to set up a persistent log in for a day.
Basically I have gotten as far as managing to set a cookie, with a value of the session username. This value is set when the user logs on.
So the user enters credentials, php checks against mysql database, if it is successful then the username is set as session variable, and this is then set as a cookie.
This works, as if I run this php and immediately echo the cookie, the username is displayed.
This is all done on my login form which is brought up in a tinybox (similar to a lightbox and other such pop up windows). The cookie and echo seems to work correctly from here.
However, when the login is successful, it refreshes the parent page, (root page of my site) and all seems well. However, if I then try to echo the cookie from the index page, I can not access it.
I know cookies have limitations on them for security, but seeing as how my login page, and my home page are on the same domain, then I thought this would have worked.
Is this something I am likely doing wrong, or is it a cookie limitation. Would it work if I set the cookie from the index page itself, rather than from within a tinybox?
If anyone wants examples of the code I am using, it can be provided.
Many thanks

Was helped out by DaveRandom on this one.
Turns out I had to add “/” as the root path for the cookie, so that it was available to parent pages.
