Halo Master semua, Saya mau tanya tentang Select2 & ajax, Saya ingin menampilkan data sesuai gambar berikut, caranya gimana ya ?



koding yang saya gunakan dibawah ini cuman menampilkan pencarian nama customer saja.

 <?php

require_once "koneksi.php";

echo"<select name="id_location" class="js-locationList form-control" required="required">

 <option value='' selected>Select Location</option>"; 

 ?>

//List ajax for list location

 $(".js-locationList").select2({

 ajax: {

 url: "customerList.php",

 type: "post",

 dataType: 'json',

 delay: 250,

 data: function (params) {

 return {

 q: params.term, // search term

 };

 },

 processResults: function(data){

 return { results: data };

 },

 cache: true

 },

 minimumInputLength: 3,

});

customerList.php

<?php 

// connect to database 

require('koneksi.php');



$q = $_POST['q'];

 

$sql = mysqli_query($konek,"select id_customer as id, nik as nik, nama_customer as text from customer where nama_customer like '%".$q."%'");

$num = mysqli_num_rows($sql);

if($num > 0){

 while($data = mysqli_fetch_assoc($sql)){

 $tmp[] = $data;



 }

} else $tmp = array();

 

echo json_encode($tmp);



?>

saya pinginnya menampilkan nik dan nama_customer dengan value option id_customer (

<option value="$r[id_customer]">$r[nik] - $r[nama_customer]</option>

).
