Koneksi Android Dengan PHP, Mysql dan Web Hosting

Bismillahirrahmanirrahim 
Assalamualaikum Wr. Wb.

Nerusin Postingan yang kemaren tentang Belajar Android, ane nyobain koneksi android dengan php, Mysql dan web hosting

Koneksi+Android

 1. Daftar di Hostingan Gratis
Ane Daftar dulu di hostingan gratis, sekalian milih domain yang udah di sediain sama servernya. untuk project android ini ane pake hostinger, silahkan sobat cari sendiri hostingan gratis yang sesuai dengan pilihan sobat…Mohon maaf ane ga ngebahas tentang cara daftar di hosting gratis ataupun dapet domain gratis ya sob, silahkan goggling sendiri aja. Setelah nunggu konfirmasi 24 Jam Baru ada balasan dari pihak Server hosting  via e-mail mengenai pendaftaran 



 2.  Aktifasi di Server Hosting
Setelah menerima e-mail ane langsung aktifasi dan mencoba alamat url http://dedendeni75.id1945.com  yang udah ane daftarin di server, tapi masih kosong he…he…



3. Membuat dan Menjalankan PHP 
Sekarang ane membuat file php untuk testing ke server hosting, 
ane buat dulu folder dengan nama android_connect dan file php dengan nama test.php



kemudian ane upload ke server hosting menggunakan file zilla 
dan ane coba koneksi phpnya http://dedendeni75.id1945.com/test.php dan hasilnya “Welcome, I am connecting Android to PHP, MySQL“. sesuai dengan script php di atas.

 4. Membuat Tabel dan Database Mysql
Membuat Database yang simpel dengan sebuah tabel



5. Koneksi Database Mysql Menggunakan PHP 
Untuk koneksi database Mysql menggunakan php ane buat dua file php dengan nama db_config.php dan db_connect.php


1. db_config.php


perhatikan tanda panah untuk user, password, database dan server. Sesuaikan dengan punya sobat.
2. db_connect.php
connect();
    }
 
    // destructor
    function __destruct() {
        // closing db connection
        $this->close();
    }
 
    /**
     * Function to connect with database
     */
    function connect() {
        // import database connection variables
        require_once __DIR__ . '/db_config.php';
 
        // Connecting to mysql database
        $con = mysql_connect(DB_SERVER, DB_USER, DB_PASSWORD) or die(mysql_error());
 
        // Selecing database
        $db = mysql_select_db(DB_DATABASE) or die(mysql_error()) or die(mysql_error());
 
        // returing connection cursor
        return $con;
    }
 
    /**
     * Function to close db connection
     */
    function close() {
        // closing db connection
        mysql_close();
    }
 
}
 
?>

6. Operasi MySql CRUD ( create, Read, Update, Delete) Menggunakan PHP

get_product_details.php 
0) {
 
            $result = mysql_fetch_array($result);
 
            $product = array();
            $product["pid"] = $result["pid"];
            $product["name"] = $result["name"];
            $product["price"] = $result["price"];
            $product["description"] = $result["description"];
            $product["created_at"] = $result["created_at"];
            $product["updated_at"] = $result["updated_at"];
            // success
            $response["success"] = 1;
 
            // user node
            $response["product"] = array();
 
            array_push($response["product"], $product);
 
            // echoing JSON response
            echo json_encode($response);
        } else {
            // no product found
            $response["success"] = 0;
            $response["message"] = "No product found";
 
            // echo no users JSON
            echo json_encode($response);
        }
    } else {
        // no product found
        $response["success"] = 0;
        $response["message"] = "No product found";
 
        // echo no users JSON
        echo json_encode($response);
    }
} else {
    // required field is missing
    $response["success"] = 0;
    $response["message"] = "Required field(s) is missing";
 
    // echoing JSON response
    echo json_encode($response);
}
?>
get_all_products.php 
0) {
    // looping through all results
    // products node
    $response["products"] = array();
 
    while ($row = mysql_fetch_array($result)) {
        // temp user array
        $product = array();
        $product["pid"] = $row["pid"];
        $product["name"] = $row["name"];
        $product["price"] = $row["price"];
        $product["created_at"] = $row["created_at"];
        $product["updated_at"] = $row["updated_at"];
 
        // push single product into final response array
        array_push($response["products"], $product);
    }
    // success
    $response["success"] = 1;
 
    // echoing JSON response
    echo json_encode($response);
} else {
    // no products found
    $response["success"] = 0;
    $response["message"] = "No products found";
 
    // echo no users JSON
    echo json_encode($response);
}
?>

            // user node
            $response["product"] = array();
 
            array_push($response["product"], $product);
 
            // echoing JSON response
            echo json_encode($response);
        } else {

Koneksi Android Dengan PHP, Mysql dan Server Hosting  ane akhirnya selesai tinggal nyobain pengoprasiannya lewat emulator android, tentunya harus konek internet sob..., ah keburu abis pulsanya he...he...he...



Oke lannnjuttt...jalankan androidnya, lalu buka mainscreen

















Dari database yang udah ane input diantaranya Iphone 4S, Macbook Pro, Mackbook Air dan OS X Lion sekarang ane tambahin Buku Belajar Android 













Maka pada Database Server Hosting akan tambah satu inputan yaitu Buku Belajar Android, untuk melihatnya masuk ke server hostingan yang sobat gunakan lalu buka tabel products.













Untuk create product, update product, delete product, view dll silahkan sobat coba sendiri. 







Oh iya sob untuk script sepenuhnya milik Mr. Ravi Tamada dan dapat sobat download di websitenya 








Dikarenakan beberapa sebab diantaranya penggantian template yang berulang-ulang perubahan script asli dari program android dan beberapa error lainnya yang mengakibatkan penulisan script code pada syntax highlighter tidak sesuai pada postingan dan kebetulan ane masih newbie bloging, ane mohon maaf. 



Jika sobat ingin mencoba koneksi android secara offline, sobat bisa mencoba postingan ane tentang 

Koneksi Android, PHP, MySQL Offline Menggunakan Xampp For Windows 1 ( Cloud Computing ) membahas tentang apa saja keperluan untuk melakukan koneksi Android, PHP, MySQL secara offline.

Koneksi Android, PHP, MySQL Offline Menggunakan Xampp For Windows 2 ( Cloud Computing )

membahas tentang pembuatan program Androidnya disertai scrip codenya.
