Topic awaiting preservation: Got a cookie() ?

So I've been playing around with code from the themeswitch.php thread... and I had a few Q's to ask:

If you get cookie info like this: $var = $HTTP_COOKIE_VARS['var'];
What is $var 's value if the user is a first time user and doesn't have a cookie from my site...

-or-

Is there a way to check for the cookie first then run thru a few if's to see what action should be taken?

Trust me... more to follow.

If you haven't written the cookie yet (which would include a value), then that variable would be empty.

So your saying $var would be " " right? Or are we talking null or 0 here?

<?

$var = $HTTP_COOKIE_VARS['var'];

if ($var == ' ' && $var2 = ' ' ) { 01 }

elseif ($var2 != ' ') { 02 }

else { 03 }

?>

So... there's my 'code' (changed ever so slightly.. heh) When a person comes to my site... its checks for var in a cookie... If both var and var 2 are empty... 01 should trigger.

If var2 isn't empty.. (or ' ' as Pugzly said) 02 should trigger

and then 03 if we must..

I thought I RTFM'd enough.. and my VB background says thats all good... but it just doesn't work...

ohyeah... var2 comes from a form action=$PHP_self so as far as I know.. the $var2 should still be around.

/me looks for his dunce cap.

Take a look at empty() function...

BTW String variable is empty only when it's equal to "" (there's no space).

First off Thanks mr.maX and who could forget Pugzly...

So I figured it out for the most part... the empty() was ok... but I still can't get this to trigger...

elseif ("$var" != " ") {
//elseif ("$var" != "") {
//elseif ("$var" != '') {
//elseif (!empty($var)) {
SetCookie("var",$var,time()+864000);
switch ($var){ }
}

That picks up the $var from the form which is located below V

The code that I've commented out are the past tries I've used... hasn't worked....

Basically... I don't know if my var is being carried over from the form when I press submit... I could do if $var = bleh but that would be messy and time consuming. *shrug*

Thanks again guys.

IF you want to quickly check your cookies you can just loop through the $HTTP_COOKIE_VARS array.


foreach ($HTTP_COOKIE_VARS as $key => $val) {
echo "Cookies!<br>"
echo "I have set the cookie named $key as \"$val\"<br>";
}

Deethree, it would be best to show us your complete code, because the problem is probably located somewhere else...

Interesting idea... would
