I’m late to the party on this one, but with The Events Calendar changing their codebase so often, this may be useful to anyone trying to do this in 2023:
In edit-event.php, you need to call the ACF form head:
add_action( 'get_header', 'call_acf_form_head', 1 );
function call_acf_form_head() {
acf_form_head();
}
In the same file, you can add your field groups anywhere within the form tags:
<?php
$settings = array(
'field_groups' => array('group_649542db656b2'),
'form' => false
);
acf_form($settings);
?>
Then in your functions.php you need to add two functions. One that fires when the event is created, and one that fires when the event is updated.
add_action('tribe_community_event_created', 'events_custom_field_create', 10, 1);
function events_custom_field_create($event_id){
acf_save_post( $event_id );
}
add_action('tribe_community_event_updated', 'events_custom_field_update', 10, 1);
function events_custom_field_update($event_id){
acf_save_post( $event_id );
}
Note: I did try combining this into one function, but for me it didn’t work.
Bonus bits:
Need to add a featured image? In your image field settings, set the Field Name as _thumbnail_id.
Want to use an image gallery, but also want to set a featured image without needing a separate field? You can save the first image uploaded to the gallery as the featured image for the event with this function:
add_filter('acf/save_post', 'gallery_to_thumbnail');
function gallery_to_thumbnail($event_id) {
$gallery = get_field('event_gallery', $event_id, false);
if (!empty($gallery)) {
$image_id = $gallery[0];
set_post_thumbnail($event_id, $image_id);
}
}
Make sure to replace the get_field with your Field Name.
I hope this helps someone!
