i think you need to loop through your CP and Repeater and build a array first, and after that echo events out of that array.
important for ordering by date is: that you set Return Format to Ymd (you can change this later with date/date_i18n)
/*build and fill: cp-loop and repeater loop*/
if(have_posts()) : while(have_posts()) : the_post();
$get_event_name = get_field('my_event_name');
if( have_rows('repeater_field_name') ):
while ( have_rows('repeater_field_name') ) : the_row();
$my_event_date = get_sub_field('my_event_date');
$get_date = (get_sub_field('my_event_date'));
$get_date_day = date('d', strtotime($get_date));
$get_date_month = date('m', strtotime($get_date));
$get_date_year = date('Y', strtotime($get_date));
$the_ID = get_the_ID();
/*of course you can extend this with additional fields or infos for that event that you can use later*/
$array[$get_date_year][$get_date_month][$get_date_day][$the_ID]['date'] = $my_event_date;
$array[$get_date_year][$get_date_month][$get_date_day][$the_ID]['name'] = $my_event_name;
endwhile;
endif;
endwhile;
endif;
/*output*/
/*i assume you extract year and month from today (example here next month)*/
$today = date('Ymd');
$d = new DateTime($today);
$d->modify( 'first day of next month' );
$year_youwish = $d->format( 'Y' );
$month_youwish = $d->format( 'm' );
$array_month_youwish = $array[$year_youwish][$month_youwish];
asort($array_month_youwish);
foreach ($array_month_youwish as $key_day => $row_day){
foreach ($row_day as $key_event => $row_id){
$event_name = $row_id['name'];
$event_date = $row_id['date'];
$event_date_pretty = date_i18n( 'j. F Y', $event_date);
echo $event_date_pretty .' : '. $event_name;
}
}
hope that help
