Hi!
It's because the grouped results structure is a bit different. I quickly put together a working snippet on how to handle grouped and non grouped results:
add_filter('asp_results','filter_asp_results');
function filter_asp_results($results){
/* If the results are grouped */
if (isset($results['grouped'])) {
foreach ($results['items'] as $i_k=>$data) {
if ($i_k == 'name') continue;
// $result['data'] holds the results here
foreach($results['items'][$i_k]['data'] as $r_k=>$res) {
// let's make it easier to access a result
$result = &$results['items'][$i_k]['data'][$r_k];
// changes are need to be made to the $result variable to take effect here
$result->title = "xyz"; //test example
/* Your code here */
}
}
/**
* You need to return the $results variable here,
* since the changes are made directly
**/
return $results;
/* Non-grouped */
} else {
foreach($results as $k => $result) {
$result = &$results[$k];
$result->title = "xyz"; //test example
/* Your code here */
}
}
}
I think if you read through the comments you will understand 😉
Let me know if you need more help!
