I have an ACF repeater field field_5f71d4eaaf381 for email addresses and I want to output a comma separate list of the sub field values (measurement_extra_email_address) to create a $to for the WordPress mail function.

			$values			  = $_POST['acf'];
			$extra_recipients = $_POST['acf']['field_5f71d4eaaf381'];

			if ( $extra_recipients ) {
				$list = array();
				foreach( $extra_recipients as $extra_recipient ) {
					$list[] = $extra_recipient['measurement_extra_email_address'];
				}
				$to = implode(',', $list);
			}

I thought above code should/would do it but no email is being send so I guess the code is incorrect..?

Just a note: When I remove above part of the code and just try $to = '[email protected]'; an email is being send so the error should be in there…

Here’s the code I was looking for:

			$values	= $_POST['acf'];
			$measurement_mail_extra_recipients = $_POST['acf']['field_5f71d4eaaf381'];

			if ( $measurement_mail_extra_recipients ) {
				$list = array();
				foreach( $measurement_mail_extra_recipients as $measurement_mail_extra_recipient ) {
					$list[] = $measurement_mail_extra_recipient['field_5f71d55aaf382', $measurement_client];
				}
				$to = implode(',', $list);
			}
