ah well..

If we look at the code logically.. you input the $_POST into the $fields variable.. then change the value of one of the array keys in $fields, but $_POST is never really altered.. $fields != $_POST if you see what I mean 🙂

So your code works in a sense but it is not affecting the actual values being saved.

I think this should work:

function my_acf_save_post( $post_id )
{
	// vars
	$fields = false;
 
	// load from post
	if( isset($_POST['fields']) )
	{
		$fields = $_POST['fields'];
		
		// concert details
		
		// event start date
		//$fields['field_5217ac66687dc']
		// event end date
		//$fields['field_524b4ca5ff418']
		
		if( empty( $fields['field_524b4ca5ff418'] ) )
			$_POST['fields']['field_524b4ca5ff418'] = $fields['field_5217ac66687dc'];
		
		// calendar details
		
		// event start date
		//$fields['field_524b4c06af2a2']
		// event end date
		//$fields['field_524b4c3aaf2a4']
		if( empty( $fields['field_524b4c3aaf2a4'] ) )
			$_POST['fields']['field_524b4c3aaf2a4'] = $fields['field_524b4c06af2a2'];
	}
 
	// ...
}
 
// run before ACF saves the $_POST['fields'] data
add_action('acf/save_post', 'my_acf_save_post', 1);

I suppose you could clean that up a bit if you like and I’m not 100% sure if I wrote the $_POST[‘field’][‘fieldkey’] correctly since I havent looked at the arrays myself but all in all it should set you on the right path!
