Question

How do i put an session array into mysql rows?

Session array output when using print_r($_SESSION['producten']):

Array
(
    [producten] => Array
        (

            [0] => Array
                (
                    [product_id] => 3
                    [aantal] => 2
                )

            [1] => Array
                (
                    [product_id] => 2
                    [aantal] => 1
                )

        )
)

Mysql:

$order_ins = "INSERT INTO orders_products (order_id,product_id,product_amount) VALUES
('".$_SESSION['order_id']."', '".$_SESSION['product_id']."','".$_SESSION['aantal']."' )";

mysql_query($order_ins) or die("Ehh..error!?" . mysql_error());

What I want is that the “product_id” and “aantal” (means amount in dutch) will be inserted in mysql rows. Afterwards the products and amounts can be filtered using the “order_id”

Answer 1

This should work, however, be aware of the risk of SQL injection.

$sql = "INSERT INTO orders_products (order_id, product_id, product_amount) VALUES ";

$i = 1;

foreach($_SESSION[producten] as $innerArray) {
    $sql .= '(' . $_SESSION[order_id] . ', ' . $innerArray[product_id] . ', ' . $innerArray[aantal] . ')';

    if($i < count($_SESSION[producten])) $sql .= ', ';

    $i++;
}

mysql_query($sql) or die("Ehh..error!?" . mysql_error());

Result

The value of $sql would be:

INSERT INTO orders_products (order_id, product_id, product_amount) VALUES (#, 3, 2), (#, 2, 1)
