Thanks for your reply,
yeah but that doesn't mean you have to start replying to just me,
keep your replies on list please - it helps others, and stops me from
getting the feeling I'm your personal bug fixer.
This is what I have so far
if (isset($add)){
$pakora++;
$pakora will only exist if you set or if register_globals
is turned on. (I get the feeling you have register_globals turned on -
not the recommended setting IMO)
setcookie("cookie[pakora]", "$pakora Pakora");
try dumping the contents of $_COOKIE:
var_dump($_COOKIE);
I would imagine the following gives you the number you are looking for:
echo intval($_COOKIE['cookie']['pakora']);
so...
<?php
if (!isset($_COOKIE['cookie']['pakora'])) {
$pakora = 0;
} else {
$pakora = intval($_COOKIE['cookie']['pakora']);
}
if (isset($add)) {
$pakora++;
setcookie("cookie[pakora]", "$pakora Pakora");
}
}
I just cannot seem to get the syntax right. when I try and use
$_COOKIE['pakora'] i get an undefined index error. I am trying to
increment the value of $pakora by 1 evert time .
thanks again,
Ross

Hi,
I want to increment a cookie by 1 every time a click a button
if (isset($add) {
$number++;
setcookie("cookie[number]", "$number Is the number")
}
I know I should retireve the cookie value for $number but the problem
is it has 2 bits, a number and a bit of text.
in your case this can be done simply:
$number = 99;
$string = "$number Is the number";
echo "the number is ",intval($string),"\n";
this works because the number is at the start of the string...
(and because of the cool way the made type conversion work in php)
to find out more search/read the manual on the subject of
typecasting/conversion.
Thanks,
