[PHP] Setting cookie on first visit
I am using a cookie to detect what skin a user wants to display. The
problem is if a user visits the site for the first time the cookie is
not being set. I am detecting if its being set or not with
if(!isset($_COOKIE['skin'])){ ... }
It's not setting the cookie untill a user refreshes the page once. How
can I ensure it's set when it hasnt been set before?

RE: [PHP] Setting cookie on first visit
When the user first visits your site, there is no skin in your cookie. Then
you can give a default value. And after the user modifies his/her profile,
you can set it to the cookie. So I don't think it is a problem of setting
cookie.

The manual detail this issue:
http://ca.php.net/setcookie
You can't see the cookie until you hit the next page. There is no way
view the newly set cookie.

Sure it's being set.
That's how you see it when they refresh the page.
$_COOKIE tells you want Cookies the browser *sent* with the request for
the URL.
It's up to you to track within that script what Cookies you are sending
*back* with the answer.
That sounds kinda harsh, and I can see why you'd want it to work the other
way -- as I first did.
But you *need* COOKIES to be what the browser sent initially.
I guess you *could* start doing things like:
?php
setcookie('var', $value);
$_COOKIES['var'] = $value;
?
and then it would do what you want...
But you could quickly confuse yourself about what came *in* from the
browser and what you are sending *out* to the browser.
Probably better for you to take a step back and think about how cookies
work, and who sends what where.

Why not use sessions instead?
