Cara Membuat Comobox Tingkat atau Berantai

Hai selamat datang di blog saya kali ini saya akan membagikan cara bagaimana sih cara buat comobox bertingkat dan saling berkaitan ( Insert Dynamic Multi Select Box Data ) itu menggunakan Php, Database, Jquery dan Ajax ? Nah kali ini saya aka membahas tentang hal itu so ikutin tutorial dibawah ya.

Tutorial yang saya bagikan ini pun bisa mengatasi permasalahan kalian yang ingin menyimpan hasil comobox bersifat huruf atau nama yang dipilih bukan malah id nya yang diambil ( berdasarkan pengalaman pribadi hehe ).

Dibawah ini adalah contoh hasil tutorial saya.



Penasaran cara membuat nya ? Oke ikutin tutorial saya dibawah ya cekidot.

Pertama 

Kamu buatlah terlebih dahulu database nya dengan nama "testing" tanpa tanda peti atau bebas namun saya sarankan mengikuti dulu agar kalian tidak bingung. 

Cara Membuat Comobox Tingkat atau Berantai

Lalu kamu buat tabel dengan nama country_state_city dengan struktur dan isi tabel sebagai berikut.

Dan buat satu lagi tabel untuk menyimpan hasil inputan dengan nama country_state_city_form_data dengan struktur tabel sebagai berikut.

Kedua

Selanjutnya kamu buka notepad atau sejenisnya lalu ketikan koding berikut dan save dengan nama database_connection.php

<?php
//database_connection.php
$connect = new PDO("mysql:host=localhost;dbname=testing", "root", "");
?>

Ketiga

Kamu buat file baru lagi di notepad atau sejenisnya ketikan koding berikut dan save dengan  nama index.php

<?php
//index.php

include('database_connection.php');

$country = '';

$query = "
SELECT country FROM country_state_city GROUP BY country ORDER BY country ASC
";
$statement = $connect->prepare($query);

$statement->execute();

$result = $statement->fetchAll();

foreach($result as $row)
{
$country .= '<option value="'.$row["country"].'">'.$row["country"].'</option>';
}

?>

<br /><br />
<div class="container" style="width:600px;">
<h2 align="center">Insert Dynamic Multi Select Box Data using Jquery Ajax PHP</h2><br /><br />
<form method="post" id="insert_data">
<select name="country" id="country" class="form-control action">

</select>
<br />
<select name="state" id="state" class="form-control action">

<br />

</select>
<br />

<input type="submit" name="insert" id="action" class="btn btn-info" value="Insert" />
</form>
</div>
</body>
</html>

<script>
$(document).ready(function(){



$('.action').change(function(){
if($(this).val() != '')
{
var action = $(this).attr("id");
var query = $(this).val();
var result = '';
if(action == 'country')
{
result = 'state';
}
else
{
result = 'city';
}
$.ajax({
url:'fetch.php',
method:"POST",
data:{action:action, query:query},
success:function(data)
{
$('#'+result).html(data);

}
})
}
});

$('#insert_data').on('submit', function(event){
event.preventDefault();
if($('#country').val() == '')
{
alert("Please Select Country");
return false;
}
else if($('#state').val() == '')
{
alert("Please Select State");
return false;
}
else if($('#city').val() == '')
{
alert("Please Select City");
return false;
}
else
{

var form_data = $(this).serialize();
$.ajax({
url:"insert.php",
method:"POST",
data:form_data,
success:function(data)
{
$('#action').attr("disabled", "disabled");
if(data == 'done')
{

$('#insert_data')[0].reset();
alert('Data Inserted');
}
}
});
}
});

});
</script>

Keempat

Masih buat file di notepad ketikan koding berikut dan save dengan nama fetch.php

<?php
//fetch.php

if(isset($_POST['action']))
{
include('database_connection.php');

$output = '';

if($_POST["action"] == 'country')
{
$query = "
SELECT state FROM country_state_city
WHERE country = :country
GROUP BY state
";
$statement = $connect->prepare($query);
$statement->execute(
array(
':country' => $_POST["query"]
)
);
$result = $statement->fetchAll();
$output .= '<option value="">Select State</option>';
foreach($result as $row)
{
$output .= '<option value="'.$row["state"].'">'.$row["state"].'</option>';
}
}
if($_POST["action"] == 'state')
{
$query = "
SELECT city FROM country_state_city
WHERE state = :state
";
$statement = $connect->prepare($query);
$statement->execute(
array(
':state' => $_POST["query"]
)
);
$result = $statement->fetchAll();
$output .= '<option value="">Select City</option>';
foreach($result as $row)
{
$output .= '<option value="'.$row["city"].'">'.$row["city"].'</option>';
}


}
echo $output;
}

?>

Kelima

Kamu buat koding insert di notepad untuk menyimpan data comobox ke database. ketikan koding berikut dan simpan sebagai insert.php

<?php
//insert.php

if(isset($_POST['country']))
{
include('database_connection.php');
$query = "
INSERT INTO country_state_city_form_data (country, state, city)
VALUES(:country, :state, :city)
";
$statement = $connect->prepare($query);
$statement->execute(
array(
':country' => $_POST['country'],
':state' => $_POST['state'],
':city' => $_POST['city']
)
);
$result = $statement->fetchAll();

if(isset($result))
{
echo 'done';
}

}

?>

Keenam

Buatlah koding css agar tampilan terlihat menarik dengan cara ketikan koding berikut dan simpan sebagai jquery.lwMultiSelect.css

/* multi select */
.lwms-main
{
font-family: Arial,Helvetica,sans-serif;
background: url('doublearrow.png') no-repeat 204px 110px;
/*width:435px;*/
width:100%;
}

.lwms-main .lwms-left, .lwms-main .lwms-right
{
/*width: 200px; */
width:45%;
color: #555;
float: left;
}

@media only screen and (max-width: 480px) {
    .lwms-main .lwms-left, .lwms-main .lwms-right
{
/*width: 200px; */
width:100%;
float: none;
}
}

.lwms-main .lwms-list{
  -webkit-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
  -moz-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
  box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
  border: 1px solid #ccc;
}

.lwms-selected{display:none;}

.lwms-main .lwms-left{margin-right: 35px;}

.lwms-main ul{margin: 0; list-style-type: none;}

.lwms-main ul.lwms-list{
  height: 150px;
  padding: 0px 0px;
  overflow-y: auto;
  background:#fff;
}

.lwms-main .lwms-left li.lwms-selectli,
.lwms-main .lwms-right li.lwms-selectli{
  padding: 4px 10px;
  color: #555;
  font-size: 12px;
  line-height:16px;
  border-bottom:1px solid #D4D4D4;
}

.lwms-filterhead {
  color: #4A4A4A;
  font-size: 12px;
  font-weight: bold;
  height: 25px;
  line-height: 25px;
  margin-top: 5px;
  vertical-align: middle;
}

.lwms-filterhead a {
  color: #4A4A4A;
  text-decoration: none;
}

.lwms-filcount {
  color: #078697;
  font-size: 14px;
}

.lwms-filterhead a:hover { text-decoration: underline; }

.lwms-main li.lwms-selectli:hover,
.lwms-main .lwms-right li:hover{
  cursor: pointer;
  text-decoration: none;
  color:#fff;
  background-color: #1a849b;
}

/* clear fix */
.lwms-cf:after { content: "."; display: block; clear: both; visibility: hidden; line-height: 0; height: 0; }
.lwms-cf { display: inline-block;}
html[xmlns] .lwms-cf {display: block;}
* html .lwms-cf { height: 1%;}


Ketujuh

Terakhir kamu buat JQuery nya dengan cara ketikan coding berikut dan simpan sebagai jquery.lwMultiSelect.js

Nah sekarang kamu coba jalankan file nya di htdocs dan kamu cek hasil inputan nya masuk atau engga di database nya. Jika sudah berhasil selamat kamu sukses mengikuti tutorial diatas. namun jika masih gagal bisa di tanyakan di komentar ya..

Oke See u Next Time Guys...
