You can do it in 3 steps:

1. Add the custom code below into your Child Theme into functions.php:

function add_page_url_name_divi() {
    $page_url = get_permalink(); // Page's URL
    $page_name = get_the_title(); // Page's name/title
    ?>
    <script>
        jQuery(document).ready(function($) {
            $('input[data-original_id="page_url"]').val('<?php echo esc_html( $page_url ) ?>'); // inserts the page url into the page url field
            $('input[data-original_id="page_url"]').prop('readonly', true); // stops auto fill from changing the value
            $('input[data-original_id="page_name"]').val('<?php echo esc_html( $page_name ) ?>'); // inserts the page name into the page name field
            $('input[data-original_id="page_name"]').prop('readonly', true); // stops auto fill from changing the value
        });
    </script>
    <?php
}
add_action('wp_footer', 'add_page_url_name_divi'); // wordpress action to insert code into the footer of your website

This PHP function (code with included jQuery script) will be added into your WordPress footer and will be used for tracking the page's URL + page's name;

You can read the comments to understand the code better.

It will look like this in the source of your Divi site (to see the source code of the web-site use: CTRL + U):

2. On the page with the Contact Form Module create 2 additional fields with the display: none CSS property (see the screenshots below).

The names should be:

• page_url
• page_name

Here are the screenshots with the properties:

The same properties should be added to the page_name attribute:

3. Add %%page_name%% and %%page_url%% as message patterns into the e-mail template.

It should look something like this:

Your e-mail will look like this:
