Я хотел бы создать функцию автозаполнения, я пробовал автозаполнение, я обнаружил, что автозаполнение не работает. Может кто-то поможет мне решить эту проблему. Я надеюсь, что кто-то может поделиться или дать предложение, чтобы я мог исправить свой код и заставить его работать. Код изначально не был моим, я изменил код, взятый из интернет-источников.Авто Завершить поиск

Это мой searchKeyRider.php

$db = new DB_CONNECT();
$keyword=$_GET["keyword"];
//$fullname =$_GET["fullname"];
//get all rides from table rides
$result = mysql_query("SELECT ID,fullname FROM rider WHERE fullname LIKE '%$keyword%' LIMIT 0, 20")
or die(mysql_error());
//check for empty result
if(mysql_num_rows($result) > 0) {
//loop all result and put into array rides
$response["rider"] = array();
while ($row = mysql_fetch_array($result)) {
//temp array
$rider = array();
$rider["riderID"] = $row["ID"];

//push single ride into final response array
array_push($response["rider"], $rider);
}
//success
$response["success"] = 1;
//print JSON response
echo json_encode($response);
} else {
//no rides found
