I'm trying to create a shopping cart but I need help with arrays.
if(!isset($_SESSION["cart_array"])||count($_SESSION["cart_array"])<1){
// RUN IF THE CART EMPTY OR NOT SET
$_SESSION["cart_array"]=array(1=>array("item_id"=>$pid,"quantity"=>1, "item_size" => $size, "item_color" => $color)); //quantity => $quantity (can be applied)
}else{
// RUN IF THE CART HAS AT LEAST ONE ITEM IN IT
foreach($_SESSION["cart_array"] as $each_item){
$i++;
while(list($key,$value) = each($each_item)){
if($key=="item_id" && $value==$pid ){//|| $key == "item_size" && $value == $size || $key == "item_color" && $key == $color
// That item is in cart already so let's adjust its quantity using array_splice()
array_splice($_SESSION["cart_array"],$i-1,1,array(array("item_id"=>$pid,"quantity"=>$each_item['quantity']+1))); //$quantity + 1 can also be applied
$wasFound=true;
} // close if condition
} // close while loop
} // close foreeach loop
if($wasFound == false) {
array_push($_SESSION["cart_array"],array("item_id"=>$pid,"quantity"=>1,"item_size" => $size, "item_color" => $color));
}
}When a user adds an item to cart. its supposed to create a new array for each product and update the quantity if its the same product id. I got that going, but the problem is when I try to include size and color. When I try to add the same product but different size and color, it doesn't create a new array and it just adds a quantity to my cart and updates my size and color. Can someone help?
Thank you
