仅使用PHP mail（）发送填充字段

Question

I'm finishing up an online menu for a fine dining client. For each item, the user can enter the desired quantity.

When the user finishes selecting and submits the form, I want a confirmation email to go to the user and to the restaurant owner (the same message).

In the confirmation email, I only want to display items for which they've entered a quantity. E.g.:

Foie Gras 1 $9ea
Steak au Poivre 2 $37ea

I know this is probably straightforward, but I can't conceptualize at what point the script checks for something like !="". Or something.

Here's the menu for your reference: http://www.greenroomgrille.com/valentines/

Thanks so much in advance.

You could run through a foreach and concat the values that have quantities:

$order = "";
foreach ($items as $item => $quantity) {
  if ($quantity > 0)
    $order .= "{$item} {$quantity}
";
}
print $order;

This assumes an array like this:

$items = array("Pudding" => 3, "Yogurt" => 12, "Soup" => 0, "Apples" => 0);
