Hello again, I tried solving this by myself, but no luck so far.
For context :
– “Cities” is a repeater field. Each row is a “city” (a city where you stop while on a road trip).
– For each row (city), I ask for start_date and end_date (arrival & departure); these fields (respectively field_5d720d97435c3 and field_5d720db1435c4 are inside a group field field_5d720d70435c2)
I’d like to make sure, for each row INDEPENDANTLY that start_date < end_date
So far, as soon as a row is not valid, error appears for each row, even if its valid.
I have no idea to validate each row independantly.
Here’s my code :
function hotel_form_validate_voyage_form( $valid, $value, $field, $input )
{
// bail early if value is already invalid
if( !$valid ) { return $valid; }
$cities= $_POST['acf']['field_5d6fb2c56a359'];
foreach($citiesas $city)
{
$start_date= $city['field_5d720d70435c2']['field_5d720d97435c3'];
$end_date= $city['field_5d720d70435c2']['field_5d720db1435c4'];
$start_date_timestamp= turn_acf_date_into_timestamp($start_date);
$end_date_timestamp= turn_acf_date_into_timestamp($end_date);
if($end_date_timestamp<= $start_date_timestamp)
{
$valid = "ERROR";
}
}
return $valid;
}
add_filter('acf/validate_value/key=field_5d720d97435c3', 'hotel_form_validate_voyage_form', 10, 4);
add_filter('acf/validate_value/key=field_5d720db1435c4', 'hotel_form_validate_voyage_form', 10, 4);
(function turn_acf_date_into_timestamp is defined elsewhere and works fine)
I’d greatly appreciate help here 🙂
