Hey @DAVID,
You should be able to use the function tribe_get_custom_fields() to get the additional fields and their content for a post.
So, something like this:
$fields = tribe_get_custom_fields( get_the_ID() );
foreach( $fields as $field ) {
// Your custom code....
}
We cannot help with custom coding much so to learn more about this function I would recommend reading the function’s code directly and tinkering a bit. You can find this function in this file inside Events Calendar Pro:
events-calendar-pro/src/functions/template-tags/general.php
Head to around line 157 and you’ll see the function defined there.
I hope that helps!
George
