session - Updating PHP Shopping Card Data via $_SESSION -


i'm having trouble updating product quantity in shopping cart. use array, $productarray, store product_id, product_name, quantity, , product_price database. check if there product product id in $_session. if yes, update quantity, if not, merge $_session.

the issue here i'm not able reach code checks product_id in session variable, hence keeps merging same product shopping cart instead of updating quantity.

my code below. please let me know if there additional components should include post. thanks.

case "add":     if(!empty($_post["qty"])) {         $productbyid = $db_handle->runquery("select * products  product_id= " . $_get["pid"]);  $productarray = array($productbyid[0] ["product_id"]=>array('product_name'=>$productbyid[0]["product_name"], 'product_id'=>$productbyid[0]["product_id"], 'quantity'=>$_post["qty"], 'product_price'=>$productbyid[0]["product_price"]));          if (!empty($_session["cart_item"])) {             if (in_array([$productbyid[0]["product_id"]],$_session["cart_item"])) {                 foreach ($_session["cart_item"] $k => $v) {                     if ($productbyid[0]["product_id"] == $k)                         $_session["cart_item"][$k]["quantity"] = $_post["qty"];                 }             } else {                 $_session["cart_item"] = array_merge($_session["cart_item"],$productarray);             }         } else {             $_session["cart_item"] = $productarray;         }        }

the statement in_array([$productbyid[0]["product_id"]],$_session["cart_item"]) return false in case.

you should change isset($productbyid[0]["product_id"], $_session["cart_item"]) guest save each product info element key product id inside $_session["cart_item"] array.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
