Question

I’m just writing a PHP script to deal with PayPal IPN data. I want to check how many items have been purchased, then dynamically call $_POST['item_name1'] for each item. So it would be:

$_POST['item_name1']
$_POST['item_name2']
$_POST['item_name3']
etc

Is this a valid in PHP, I’m not getting what I expect and now sure how to test this on its own:

for ($i = 1; $i <= $number_items; $i++) {
    $items[$i] = $_POST[' . "item_name" . $i . '];
}

TIA

Almost. You want:

for ($i = 1; $i <= $number_items; $i++) {
    $items[$i] = $_POST['item_name' . $i];
}

You could also use:

$_POST["item_name{$i}"];
