PHP Email with filled in forms only - php

Question

Been struggling very much with only sending the fields that people fill in. It is a simple order form with text fields. But I want it so that only those fields that are field in get sent to my alert email. I tried the codes on the topic "PHP form: Success email with only filled fields" but my php script crashes when I do. Here is my code before I tried any modifying. This email fine only that it includes all fields I only want the one filled in. Please help I am a total noob in php. All help appreciated.

Answer 1

The errors might be related to unset POST variables.
How about a loop? It will only use what is sent over.
$message = "";
$message .= "Order has been placed. Attn to: $name .\n
Items:\n";
foreach ($_POST as $fieldName => $fieldValue){
if (!empty($fieldValue))
$message .= " ". str_replace('_',' ',$fieldName) .": $fieldValue\n";
}

Answer 2

OK I added this and worked great. How the email comes back with the field name with underscores. How to send without underscores?:
