Cookie not setting = driving me insane

Corpheous

Why in the world does this not work:

if(isset($_COOKIE['creature_hp'])) {
}
else {
	$cookie_life = time() + 31536000;
	setcookie('creature_hp', $monster_hp, $cookie_life);
	echo $monster_hp;
	echo "got here";
	echo $_COOKIE['creature_hp'];
}

$creature_hp = $_COOKIE['creature_hp'];

Here's what I get:

10got here
Notice: Undefined index: creature_hp in C:\Program Files\Apache Group\Apache2\htdocs\vod\gamev2\fight.php on line 54

Notice: Undefined index: creature_hp in C:\Program Files\Apache Group\Apache2\htdocs\vod\gamev2\fight.php on line 57

Which means to me that $monster_hp = 10 which means that the code SHOULD be getting to that point and therefore setting the cookie but then the next line defies all that by saying nothing is defined.

Help? Please?

P.S. > If I refresh the page after clicking the link to get there, it seems to sorta work. No clue why.

When using setcookie, the cookie is not actually set until the page is refreshed. So you might consider using the header function to aytomatically refresh the pages after setting the cookie.

The manual has examples.

Cookies Must Be SET ON THE VERY FIRST LINE

perrio,
NOPE.

perrio

cookie must be set before any other page-relevant information is sent to the browser

By the way
Do you know how to convert an associative array into an indexed array? I wanna do this so i can loop through the values...

LordShryku

You can loop through an associative array using foreach....

foreach($array as $key => $value) {
   echo "Key is ".$key." and value is ".$value."<br />";
}

Now I sorta remember having a problem like this before...wasn't there a workaround so I could use it on this page without refreshing the page? Something about setting the variable before the cookie gets set...
