[PHP] Session Help

[Luno1599]

Hey,

I have this code:

<?php
session_start();

if($_GET['del'] == "yes"){
session_destroy();
}

function addToCart() {
    // count at what order_line number we currently are and increment with 1 for our next line
    $order_line_id = count($_SESSION['cart']) + 1;
    $_SESSION['cart'][$order_line_id]['product_id'] = $_POST['product_id']; // unique product id, should be taken from your DB
    $_SESSION['cart'][$order_line_id]['quan'] = $_POST['quan'];
    $_SESSION['cart'][$order_line_id]['price'] = $_POST['price']; // price for each product
}


if(isset($_POST['submit'])) { // did the user press a submit button?
    addToCart(); // run the addToCart function to add the form information to the session array.
}


if($_SESSION['cart']){

$total_order_price = 0;

for($i = 0; $i <= count($_SESSION['cart']); $i++) {


    
echo "Product id : " . $_SESSION['cart'][$i]['product_id'] . "<br>";
echo "Quantity : " . $_SESSION['cart'][$i]['quan'] . "<br>";
echo "Price : " . $_SESSION['cart'][$i]['price'] . "<br>";

$line_price = $_SESSION['cart'][$i]['price'] * $_SESSION['cart'][$i]['quan'];

echo "Total price : " . $line_price . "<br><br>";

$total_order_price = $total_order_price + $line_price;

}

echo "Shipping: 4.99<br><br>";

$total_order_price_ship = $total_order_price + 4.99;

echo "Totale order price : ". $total_order_price_ship;


}else{
echo "No Cart!";
}

?>



<form action="test2.php" method="post">

  <input name="product_id" type="hidden" id="product_id" value="IMG-001">
  <input name="quan" type="hidden" id="quan" value="5">
  <input name="price" type="hidden" id="price" value="1.00">
  
  <input type="submit" name="submit" value="Add">
</form>

And when you click add, it shows this:

Product id :
Quantity :
Price :
Total price : 0

Product id : IMG-001
Quantity : 5
Price : 1.00
Total price : 5

Shipping: 4.99

Totale order price : 9.99

Why does it make one with nothing in it?!
It only does it with the first one...

Delete this post please, read the code wrong.

Also, How would you make the code check the session to check if they have already added the product and then update the quantity so it doesnt make a new session and then make duplicate sessions.
