[RESOLVED] adding extra value to text input array

[Da_Elf]

I'm listing out a bunch of products from a database using a while loop and next to it I'm placing the quantity of products. I want to be able to update the quantity, so I've placed it inside of an input field. I've used an array for the input name so that i can grab all of the entries from the while loop. however i want to add more than just the quantity to the array entries.

<input type="text" name="product[]" value="<?=$pro['product_quantity']?>" required>

This will put the quantity into the array.

What i want to do is that when the array is received via $_POST i want it to have the product id ( $pro['product_id'] ) followed by the quantity but i only want the value of the text input to show quantity. I can separate the id from the quantity later that's no problem

Try this

<input type="text" name="product[$pro['product_id']][]" value="<?=$pro['product_quantity']?>" required>

on the other side im using

$products = $_POST['product'];
foreach ($products as $p){
    echo $p."<br>";
    } 

i was going to seperate them via substr. how do i get my info now? all im getting is
Array

i need it to give something like
0011
0021
0035
00422

where the first 3 numbers are the product id and the last number(s) is the quantity

i thought that method would just set the array so that the product_id is the key and the value is the value of the key. which i cant see would work

rather than trying to fix something that doesnt seem to work. is there another way around this?

for anyone who is interested. this is how i resolved it

<?php
if(isset($_POST['update'])){
foreach ($_POST['product'] as $p){
        echo $p['product_id']." is the id and ".$p['product_quantity']." is the quantity<br>";
        }
}
$sqlpr = "SELECT product_id, product_quantity FROM products WHERE order_id = '$myorder' ORDER BY product_id";
$querypr = mysql_query($sqlpr, $myCon);?>
<form name="cartform" action="cart.php" method="post">
<?php
$pad = 0;
while ($pro = mysql_fetch_array($querypr, MYSQL_ASSOC)) {?>
<input type="text" name="product[<?=$pad?>][product_quantity]" value="<?=$pro['product_quantity']?>" required><input type="hidden" name="product[<?=$pad?>][product_id]" value="<?=$pro['product_id']?>"/><br>
<?php $pad++; } ?>
<input name="update" type="submit" value="update" />
</form>
