Suggestions
Suggestions for the AutoComplete editor can be based either on a data source (in this case you need to specify the data source name, field name, and the sort order) or on a PHP function with the following signature:
function OnGetSuggestions($term, &$suggestions);
Parameters:
$term |
Current input |
$suggestions |
Array of suggestions for the current input |
Example
The following example from our Feature Demo demonstrates how it is possible to use the Google API to get the list of suggestions. Don't forget to replace XXX to your Google API Key.
$url = 'https://maps.googleapis.com/maps/api/place/queryautocomplete/json?key=%s&input=%s';
$key = 'XXX';
$sourceUrl = sprintf($url, $key, urlencode($term));
$contextOptions = array(
"ssl" => array(
"verify_peer" => false,
"verify_peer_name" => false
)
);
$json = file_get_contents($sourceUrl, false, stream_context_create($contextOptions));
$result = json_decode($json, true);
if ($result['status'] == 'OK') {
foreach ($result['predictions'] as $prediction) {
$suggestions[] = $prediction['description'];
}
} elseif ($result['status'] == 'OVER_QUERY_LIMIT') {
$suggestions[] = 'Query limit is exceeded';
}
Minimum input length
