Question

I have an HTML order form with approx 100 possible entries. The form posts to a PHP file. The PHP file send an email with the order quantities and $totals per item.
The problem is that it sends the info when the quantity = 0 – which, of course, makes the resulting email quite cumbersome.
SO, my question is: How do I NOT send the info when the quantity is 0

Here is an example of the coding I have for the POST portion:

if( !empty($_POST[""]) )
else
{
    $qtyG01lg = 0;
    $totalG01lg = 0;
}

And here is the part I do NOT want to send if the quantity is “0”:

$body .= "     G01-large: (" . $qtyG01lg . " @ $10.00ea) = " . $totalG01lg . "\n";

Answer 1

The lines for checking if the quantity is 0 set should be,

 if( $qtyG01lg > 0 && $totalG01lg > 0 )
  $body .= "     G01-large: (" . $qtyG01lg . " @ $10.00ea) = " . $totalG01lg . "\n";

Also, you cannot have an empty string as the name/key in $_POST (if( !empty($_POST[""]) )). So, the line should be,

 if( !empty($_POST) ) //or specify the key/index for quantity or whatever you want to check
