i also would know if it is possible to auto order repeater fields at backend, based on a value inside that repeater (oder by a date-field for example)
at frontend i have no big problem. i do it like this:
foreach( $arr_merge as $key => $row ) {
$thedate = $row['termin_date'];
$column_id[ $key ] = strtotime($thedate);
}
array_multisort( $column_id, SORT_ASC, $arr_merge );
but at backend i dont know, how to do that.
if there where not may repeater rows, manually order is no big thing, but if you have about 10-100 repeater-rows, automatic order would be great. even if it would happen only after a save/update the post, not after add row.
