Hi,
Okay, I see where the problem is. The matching location names all have different IDs, despite the same names, that’s why the code has no effect. I have made an addition to the existing code, that may resolve that. As of the previous version, the plugin supports multiple values per drop-dow, when separated by double dots, such as:
value1::value2::value3||Option
Where either of the values can be matched. Based on that, I would try this solution. Be careful, as I did not test this solution, you might have to make adjustments to it:
add_filter('asp_cf_item_view', 'asp_em_locations_cf_filter', 10, 1);
function asp_em_locations_cf_filter($item) {
if ( $item->asp_f_field == '_location_id' && class_exists('EM_Locations') ) {
$location_ids = array();
foreach ( $item->asp_f_dropdown_value as $k=>$v ) {
if ( is_numeric($v[1]) ) {
$location_ids[] = $v[2];
unset($item->asp_f_dropdown_value[$k]);
}
}
$locations = EM_Locations::get( array('location'=>array_unique($location_ids)) );
$locarr = array();
if ( is_array($locations) && count($locations) > 0 ) {
foreach ( $locations as $loc ) {
if ( isset($locarr[$loc->location_town]) ) {
$locarr[$loc->location_town] .= '::' . $loc->location_id;
} else {
$locarr[$loc->location_town] = $loc->location_id;
}
$item->asp_f_dropdown_value[] = array(
$loc->location_id, $loc->location_town
);
}
ksort($locarr);
foreach ( $locarr as $key => $loc ) {
$item->asp_f_dropdown_value[] = array(
$loc, $key
);
}
}
}
return $item;
}
