Cookies, can't read 'em

[jake]

I'm having a hell of a trubble with this. There does not seem to be much in the way of PHP cookie examples around, so I must be missing somethin very basic. Here's the code...

This gets form input in the form of two arrays, stick 'em together, then sets the cookie...

<?php
$stock_string = implode (",",$stock_choice);
$feed_cookie = implode (",",$feed_choice);
$feed_cookie = $feed_cookie . "," . $stock_string;
setcookie("feed_cookie", $feed_cookie, time() + 3600);
?>

This is a section of code I would like to read the cookie, it reads the cookie in, then breaks a few chunks off the end....

$HTTP_COOKIE_VARS["feed_cookie"];
if (strlen($feed_cookie) == 0) {
$cookie_stat = 0;
} else {
$cookie_stat = 1;
$stocks = substr (strrchr ($feed_cookie, ","), 1);
$feed_cookie = substr ($feed_cookie, 0, (strlen ($feed_cookie) - strlen($stocks)));
$stocks2 = substr (strrchr ($feed_cookie, ","), 1);
$feed_cookie = substr ($feed_cookie, 0, (strlen ($feed_cookie) - strlen($stocks2)));
$stocks3 = substr (strrchr ($feed_cookie, ","), 1);
$feed_cookie = substr ($feed_cookie, 0, (strlen ($feed_cookie) - strlen($stocks3)));
}

But, alas, it does nothing because it cant see the cookie(?).

What am I missing?

here is your problem.

$HTTP_COOKIE_VARS["feed_cookie"];

You are essentially trying to execute the function named by feed_cookie. Say feed_cookie had the contents of 'hi_all' then you'd be executing the function hi_all().

Assuming that you haven't done anything radically different with your php.ini file, simply delete the line I highlighted above. PHP automatically assigns $feed_cookie to $HTTP_COOKIE_VARS['feed_cookie']. That's why I love the language

Oops, correction. You aren't executing any function by any name. Why it didn't return an error message is beyond me...

[Vinay]

what I wonder is what the intent of
$HTTP_COOKIE_VARS["feed_cookie"]; is

firstly,

$feed_cookie = $HTTP_COOKIE_VARS["feed_cookie"];

would be better.. you are essentially wiping $feed_cookie out on the top when its trying to set the cookie...

perhaps do this on the top

if($HTTP_COOKIE_VARS["feed_cookie"] != "")
{
set the cookie here
}

hmmmm. maybe i'm just confused
