Membuat CRUD Sederhana Dengan PHP Dan MySQL

Hari ini kita akan belajar Membuat CRUD Sederhana Dengan PHP dan MySQL.

CRUD adalah akronim untuk Create, Read, Update, dan Delete. Operasi CRUD adalah manipulasi data dasar untuk database. Dalam tutorial ini kita akan membuat aplikasi PHP sederhana untuk melakukan semua operasi ini pada tabel database MySQL di satu tempat.

Kita akan membuat sebuah aplikasi dengan tampilan seperti pada gambar di bawah dengan sebuah tabel yang menampilkan data dari database di sisi frontend. Terdapat beberapa tombol untuk mengubah data yang ada di database lewat antarmuka yang kita buat. Tabel pengguna yang kita buat akan berisi informasi pengguna seperti nama, nomor telepon, email, dan lain nya.

Langkah-Langkah Pembuatan CRUD

1. Persiapkan alat tempur misal menggunakan xampp

2. Membuat Database.sql

/* Create Database and Table */
create database crud_db;
 
use crud_db;
 
CREATE TABLE `users` (
  `id` int(11) NOT NULL auto_increment,
  `name` varchar(100),
  `email` varchar(100),
  `mobile` varchar(15),
  PRIMARY KEY  (`id`)
);

3. Membuat file config.php

<?php
/**
 * using mysqli_connect for database connection
 */
 
$databaseHost = 'localhost';
$databaseName = 'crud_db';
$databaseUsername = 'root';
$databasePassword = '';
 
$mysqli = mysqli_connect($databaseHost, $databaseUsername, $databasePassword, $databaseName); 
 
?>

4. 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>

5. 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>

6. 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>

7. 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");
?>
