I have successfully tested both PHP's and SMTP's functionality - both are functional.
However, I am trying to use a contact form on a webpage. When I test the form with its Submit button, the form just results in a HTTP 500 error, without any other information.
Here is the two scripts - the PHP where the form resides, and the PHP that is the form's action.
- Code: Select all
<?php
session_start();
function paint_value($field)
{
if (!empty($_SESSION["post"][$field]))
{
echo $_SESSION["post"][$field];
}
else { echo ""; }
}
?>

Can anyone give me a hand? I am at a loss as to where to start debugging/fixing this.
