3. Membuat file index.php
<?php
// Create database connection using config file
include_once("config.php");
// Fetch all users data from database
$result = mysqli_query($mysqli, "SELECT * FROM users ORDER BY id DESC");
?>
<html>
<head>
<title>Homepage</title>
</head>
<body>
<a href="add.php">Add New User</a><br/><br/>
<table width='80%' border=1>
<tr>
<th>Name</th> <th>Mobile</th> <th>Email</th> <th>Update</th>
</tr>
<?php
while($user_data = mysqli_fetch_array($result)) {
echo "<tr>";
echo "<td>".$user_data['name']."</td>";
echo "<td>".$user_data['mobile']."</td>";
echo "<td>".$user_data['email']."</td>";
echo "<td><a href='edit.php?id=$user_data[id]'>Edit</a> | <a href='delete.php?id=$user_data[id]'>Delete</a></td></tr>";
}
?>
</table>
</body>
</html>
File index.php merupakan file utama yang menyertakan file konfigurasi untuk koneksi database. Kemudian menampilkan semua daftar pengguna menggunakan MySQL Select Query. Pengguna yang akan ditampilkan di dalam daftar perlu menambahkan terlebih dahulu menggunakan tautan 'Tambahkan Pengguna Baru'.
4. Membuat file add.php
<html>
<head>
<title>Add Users</title>
</head>
<body>
<a href="index.php">Go to Home</a>
<br/><br/>
<form action="add.php" method="post" name="form1">
<table width="25%" border="0">
<tr>
<td>Name</td>
<td><input type="text" name="name"></td>
</tr>
<tr>
<td>Email</td>
<td><input type="text" name="email"></td>
</tr>
<tr>
<td>Mobile</td>
<td><input type="text" name="mobile"></td>
</tr>
<tr>
<td></td>
<td><input type="submit" name="Submit" value="Add"></td>
</tr>
</table>
</form>
<?php
// Check If form submitted, insert form data into users table.
if(isset($_POST['Submit'])) {
$name = $_POST['name'];
$email = $_POST['email'];
$mobile = $_POST['mobile'];
// include database connection file
include_once("config.php");
// Insert user data into table
$result = mysqli_query($mysqli, "INSERT INTO users(name,email,mobile) VALUES('$name','$email','$mobile')");
// Show message when user added
echo "User added successfully. <a href='index.php'>View Users</a>";
}
?>
</body>
</html>
File add.php berfungsi untuk menambahkan pengguna baru. Formulir HTML digunakan untuk menerima masukan data pengguna. Setelah data pengguna diserahkan, MySQL INSERT Query digunakan untuk memasukkan data pengguna ke dalam database.
5. Membuat file edit.php
<?php
// include database connection file
include_once("config.php");
// Check if form is submitted for user update, then redirect to homepage after update
if(isset($_POST['update']))
{
$id = $_POST['id'];
$name=$_POST['name'];
$mobile=$_POST['mobile'];
$email=$_POST['email'];
// update user data
$result = mysqli_query($mysqli, "UPDATE users SET name='$name',email='$email',mobile='$mobile' WHERE id=$id");
// Redirect to homepage to display updated user in list
header("Location: index.php");
}
?>
<?php
// Display selected user data based on id
// Getting id from url
$id = $_GET['id'];
// Fetech user data based on id
$result = mysqli_query($mysqli, "SELECT * FROM users WHERE id=$id");
while($user_data = mysqli_fetch_array($result))
{
$name = $user_data['name'];
$email = $user_data['email'];
$mobile = $user_data['mobile'];
}
?>
<html>
<head>
<title>Edit User Data</title>
</head>
<body>
<a href="index.php">Home</a>
<br/><br/>
<form name="update_user" method="post" action="edit.php">
<table border="0">
<tr>
<td>Name</td>
<td><input type="text" name="name" value=<?php echo $name;?>></td>
</tr>
<tr>
<td>Email</td>
<td><input type="text" name="email" value=<?php echo $email;?>></td>
</tr>
<tr>
<td>Mobile</td>
<td><input type="text" name="mobile" value=<?php echo $mobile;?>></td>
</tr>
<tr>
<td><input type="hidden" name="id" value=<?php echo $_GET['id'];?>></td>
<td><input type="submit" name="update" value="Update"></td>
</tr>
</table>
</form>
</body>
</html>
Edit.php digunakan untuk mengedit / update data pengguna. Anda dapat mengubah data pengguna dan memperbaruinya. File ini akan mengarahkan pengguna kembali ke homepage, setelah update sukses.
6. Membuat file delete.php
<?php
// include database connection file
include_once("config.php");
// Get id from URL to delete that user
$id = $_GET['id'];
// Delete user row from table based on given id
$result = mysqli_query($mysqli, "DELETE FROM users WHERE id=$id");
// After delete redirect to Home, so that latest user list will be displayed.
header("Location:index.php");
?>
File ** delete.php** hanya dipanggil saat kita klik link 'Delete' untuk pengguna manapun yang dipilih.
Setelah semua file di upload di htdocs pada folder Xampp di partisi C, kalilan bisa membukanya di localhost pada webrowser.
