Answer 1

Look at this line:

if ($part->disposition == "ATTACHMENT") {

Based on the details of the PHP Notice you provided, $part is an instance of stdClass. However, also based on your PHP Notice message it does not have a disposition property.

Change this line to :

if (isset($part->disposition) && $part->disposition == "ATTACHMENT") {

To ensure the property exists before calling it. Alternatively, you can use property_exists(); e.g:

property_exists($part, 'disposition');

Additionally, you might want to consider adding a condition somewhere to ensure that $part is actually an object with is_object():

is_object($part); // `true` if `$part` is any object

Or, a specific instance type with instanceof:

$part instanceof stdClass; // `true` if `$part` is a `stdClass` instance

Regarding your second question: if you have two separate questions, you should create post two separate questions. But, if you define any values in a separate .php file and want to include them in your current script, you can simply use require_once to effectively import them; e.g:

<?php

require_once __DIR__ . '/constants.php';
echo FOO;

Hope this helps :)
