An array dillema

Anon

First of all, here is my code:

<?php
if (!isset($quantity) OR $quantity == "0"){
die("<body bgcolor='FF0000'><font face=verdana color='FFFFFF'>You have no items in your shopping cart.");
}
if (!isset($cookie_cart)){
$cookie_cart = array();
}

$string = $quantity . "x " . $size . " " . $item;

$cookie_cart[] = $string;

setcookie("cookie_cart", $cookie_cart, time()+600);

print "<body bgcolor='FF0000'>\n<font face='verdana' color='FFFFFF'>";

for ($i = 0; $i < count($cookie_cart); $i++) {
print "$cookie_cart[$i] <a href='order_bottom.php?request=remove&rid=$i'>";
print "<img src='images/-.gif' border=0 height=20 width=20></a><br>";
}

I get an error where the code reads "$cookie_cart[] ...". The error reads as follows: " Fatal error: [] operator not supported for strings ". This of course makes no sense to me. $cookie_cart is not a string, it is an array. The first time this script loads it is initialized as an array, and then set as a cookie. I have been puzzling over this for a while and have no idea where the error is! Please help!

Thanks

Cookies are always strings. So even thought you set the variable as an array once you make it a cookie it's a string.

You should look at how to use sessions, then you can pass array's around.

I'm not sure if this will help, but have you tried something like this:
$cart_items = explode($cookie_cart,<delimiter>);

Then loop through $cart_items.

indeed, you better use sessions,
but if you really want to store an array or other object as a string (to store in a cookie or database) you should use serialize

I found two possible problems:

$cookie_cart[] = $string;
do you want to append the string to the array $cookie_cart?
better use:
array_push($cookie_cart, $string);

print "$cookie_cart[$i] <a href='order_bottom.php?request=remove&rid=$i'>";
This won't work because the automatic replacement will not be able to recognize that $cookie_cart[$i] is the variable name; it'll stop recognizing it before the brackets. instead, use:

print $cookie_cart[$i]." <a href='order_bottom.php?request=remove&rid=$i'>";
