How to create a blog application with PHP?


Let’s develop a basic blog application that allows users to create, view, edit, and delete blog posts. The process will include:

  • Environment Setup
  • Database and Tables Creation
  • Frontend Form Development
  • Form Submission Handling
  • Blog Post Display
  • Blog Post Editing and Deletion
  • User Authentication with Sessions.

Here’s an extensive PHP exercise that encompasses various PHP concepts such as variables, control structures, functions, arrays, forms, sessions, file handling, and database interactions. The purpose of this exercise is to create a basic blog application.

What is a blog application?

A blog application is more than just a digital canvas – it’s a powerful platform where you can share your thoughts, experiences, and ideas with the world.

It allows you to create, publish, and manage your own content through blog posts. Whether you’re an expert in your field, an adventurer, or someone with a passion to express, a blog application offers you the space to do so.

Beyond writing, a blog application is a versatile tool that can serve various purposes. It can be a community hub, a marketing tool, a portfolio showcase, and much more.

With features like content management, user authentication, interactivity options, customization tools, and SEO optimization, a blog application enables you to build a unique online presence that mirrors your personality and aspirations.

Steps to Code the Simple Blog Application with PHP

Step 1: Setting Up the Playground 🌟

Before we jump into the code, let’s confirm that our playground is ready for action. Make sure you have your trusted local web server (like Apache) with PHP and MySQL installed and set up.

If you need help with this, tools like XAMPP, WAMP, or MAMP can be very useful. Once that’s done, create a new project folder. Let’s call it super_blog.

Make sure you have a local web server (like Apache) with PHP and MySQL installed. You can use XAMPP, WAMP, or MAMP. Create a new project folder, say super_blog.

Step 2: Creating the Database and Tables 🗄️

It’s time to establish a solid foundation! Consider your database as the strong backbone of your blog application. Open up PHPMyAdmin or the MySQL command line and generate a fresh database.

How about giving it a cool name like super_blog? Within this virtual haven, we’ll create a unique space for our blog posts using a clever table. Imagine it as constructing shelves for your cherished book collection!

Fire up PHPMyAdmin or the MySQL command line and create a database:

CREATE DATABASE super_blog;
USE super_blog;

Create a table for your blog posts:

CREATE TABLE posts (
    id INT AUTO_INCREMENT PRIMARY KEY,
    title VARCHAR(255) NOT NULL,
    content TEXT NOT NULL,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

Step 3: Building the Frontend Form 🖌️

Oh, the empty canvas is ready! This is where we’ll work our magic and create amazing new blog posts. Imagine this as setting up a comfortable writing corner with a comfy chair and a hot cup of coffee.

We’ll add some HTML and PHP to create a form where you can express your thoughts in words. Don’t fret, it’s as simple as baking a batch of cookies (minus the calories).

Create an index.php file in your project folder with this code:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Super Cool Blog</title>
</head>
<body>
    <h1>Create a New Blog Post</h1>
    <form action="create_post.php" method="post">
        <label for="title">Title:</label><br>
        <input type="text" id="title" name="title" required><br><br>
        <label for="content">Content:</label><br>
        <textarea id="content" name="content" rows="10" cols="30" required></textarea><br><br>
        <input type="submit" value="Create Post">
    </form>
    <hr>
    <h1>All Blog Posts</h1>
    <?php
    include 'db_connection.php';

    $sql = "SELECT * FROM posts ORDER BY created_at DESC";
    $result = $conn->query($sql);

    if ($result->num_rows > 0) {
        while($row = $result->fetch_assoc()) {
            echo "<h2>" . htmlspecialchars($row['title']) . "</h2>";
            echo "<p>" . nl2br(htmlspecialchars($row['content'])) . "</p>";
            echo "<p><a href='edit_post.php?id=" . $row['id'] . "'>Edit</a> | <a href='delete_post.php?id=" . $row['id'] . "'>Delete</a></p>";
            echo "<hr>";
        }
    } else {
        echo "<p>No posts yet!</p>";
    }

    $conn->close();
    ?>
</body>
</html>

Step 4: Handling Form Submissions 📬

Picture this as your digital mailbox where all your blog post submissions end up. Let’s create some PHP code to receive those submissions, handle them, and securely save them in our database.

It’s similar to having a helpful mail carrier who guarantees that every letter reaches its intended destination, but in this scenario, our letters are actually blog posts!

Create a create_post.php file to handle form submissions:

<?php
include 'db_connection.php';

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $title = $_POST['title'];
    $content = $_POST['content'];

    $sql = "INSERT INTO posts (title, content) VALUES (?, ?)";
    $stmt = $conn->prepare($sql);
    $stmt->bind_param("ss", $title, $content);

    if ($stmt->execute()) {
        header("Location: index.php");
        exit();
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }

    $stmt->close();
    $conn->close();
}
?>

Step 5: Displaying Blog Posts 👀

It’s time to share your writing with the world! We’re gathering all the blog posts from our database to display them on the webpage.

Think of it as hosting your own poetry slam, but instead of snapping fingers, we’ll be clicking links and scrolling through amazing pieces.

This part is already handled in the index.php file where we fetch and display all blog posts. Sweet!

Step 6: Editing and Deleting Blog Posts ✏️❌

Oh, the magic of writing! Or in this scenario, the wonders of typing. With this feature, we can enhance our blog posts by adding the ability to edit and delete them.

It’s like having a personal editor, but instead of using red pens, all it takes is a few lines of code. You’ll have the power to refine your posts or say goodbye to the ones that have fulfilled their purpose.

Create an edit_post.php file for editing posts:

<?php
include 'db_connection.php';

if (isset($_GET['id'])) {
    $id = $_GET['id'];
    $sql = "SELECT * FROM posts WHERE id = ?";
    $stmt = $conn->prepare($sql);
    $stmt->bind_param("i", $id);
    $stmt->execute();
    $result = $stmt->get_result();

    if ($result->num_rows === 1) {
        $post = $result->fetch_assoc();
    } else {
        echo "Post not found!";
        exit();
    }
} elseif ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $id = $_POST['id'];
    $title = $_POST['title'];
    $content = $_POST['content'];

    $sql = "UPDATE posts SET title = ?, content = ? WHERE id = ?";
    $stmt = $conn->prepare($sql);
    $stmt->bind_param("ssi", $title, $content, $id);

    if ($stmt->execute()) {
        header("Location: index.php");
        exit();
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }
} else {
    echo "Invalid request!";
    exit();
}

$stmt->close();
$conn->close();
?>

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Edit Post</title>
</head>
<body>
    <h1>Edit Blog Post</h1>
    <form action="edit_post.php" method="post">
        <input type="hidden" name="id" value="<?php echo htmlspecialchars($post['id']); ?>">
        <label for="title">Title:</label><br>
        <input type="text" id="title" name="title" value="<?php echo htmlspecialchars($post['title']); ?>" required><br><br>
        <label for="content">Content:</label><br>
        <textarea id="content" name="content" rows="10" cols="30" required><?php echo htmlspecialchars($post['content']); ?></textarea><br><br>
        <input type="submit" value="Update Post">
    </form>
</body>
</html>

Create a delete_post.php file for deleting posts:

<?php
include 'db_connection.php';

if (isset($_GET['id'])) {
    $id = $_GET['id'];

    $sql = "DELETE FROM posts WHERE id = ?";
    $stmt = $conn->prepare($sql);
    $stmt->bind_param("i", $id);

    if ($stmt->execute()) {
        header("Location: index.php");
        exit();
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }

    $stmt->close();
    $conn->close();
} else {
    echo "Invalid request!";
}
?>

Step 7: Using Sessions for User Authentication 🔐

It’s time to secure your blog kingdom by locking the doors! Let’s sprinkle some session magic to verify users. Think of it as a special handshake to join an exclusive club.

Only those with the correct credentials can explore the inner workings of your blog empire.

Create a login.php file for user login:

<?php
session_start();
include 'db_connection.php';

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $username = $_POST['username'];
    $password = $_POST['password'];

    $sql = "SELECT * FROM users WHERE username = ? AND password = ?";
    $stmt = $conn->prepare($sql);
    $stmt->bind_param("ss", $username, $password);
    $stmt->execute();
    $result = $stmt->get_result();

    if ($result->num_rows === 1) {
        $_SESSION['username'] = $username;
        header("Location: index.php");
        exit();
    } else {
        echo "Invalid username or password!";
    }
}

$stmt->close();
$conn->close();
?>

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Login</title>
</head>
<body>
    <h1>Login</h1>
    <form action="login.php" method="post">
        <label for="username">Username:</label><br>
        <input type="text" id="username" name="username" required><br><br>
        <label for="password">Password:</label><br>
        <input type="password" id="password" name="password" required><br><br>
        <input type="submit" value="Login">
    </form>
</body>
</html>

Update index.php to include session checks:

<?php
session_start();
if (!isset($_SESSION['username'])) {
    header("Location: login.php");
    exit();
}
?>

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Super Cool Blog</title>
</head>
<body>
    <h1>Welcome, <?php echo htmlspecialchars($_SESSION['username']); ?>!</h1>
    <a href="logout.php">Logout</a>
    <hr>
    <!-- Rest of the code remains the same -->
</body>
</html>

Create a logout.php file:

<?php
session_start();
session_unset();
session_destroy();
header("Location: login.php");
exit();
?>

Create a db_connection.php file to handle your database connection:

<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "super_blog";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
?>

Bonus: User Registration (Because You’re Awesome!) 🎉

Finally, it’s time to extend a warm welcome! By enabling user registration, you can extend invitations to fellow bloggers and encourage them to become part of your community.

It’s just like hosting a fabulous grand opening party for your blog. Remember, the more, the merrier!

Create a register.php` file for new users to register:

<?php
include 'db_connection.php';

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $username = $_POST['username'];
    $password = $_POST['password'];

    $sql = "INSERT INTO users (username, password) VALUES (?, ?)";
    $stmt = $conn->prepare($sql);
    $stmt->bind_param("ss", $username, $password);

    if ($stmt->execute()) {
        header("Location: login.php");
        exit();
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }

    $stmt->close();
    $conn->close();
}
?>

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Register</title>
</head>
<body>
    <h1>Register</h1>
    <form action="register.php" method="post">
        <label for="username">Username:</label><br>
        <input type="text" id="username" name="username" required><br><br>
        <label for="password">Password:</label><br>
        <input type="password" id="password" name="password" required><br><br>
        <input type="submit" value="Register">
    </form>
</body>
</html>

Add a users table to your database:

CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    username VARCHAR(50) NOT NULL UNIQUE,
    password VARCHAR(255) NOT NULL
);

Congrats! You’ve built a super cool blog app that handles posts, user authentication, and more. Happy coding! 🎉🚀

Can I use a PHP script in Blogger?

Blogger, Google’s popular blogging platform, does not have built-in support for PHP scripts. It mainly works with static HTML and JavaScript in posts and pages.

However, there are ways to get around this limitation. One option is to host your PHP scripts on a server that supports PHP, such as a shared hosting provider or a virtual private server (VPS).

After uploading them, you can then link to these scripts from your Blogger content. Another possibility is to embed PHP-powered content using an tag.

This method involves creating a separate PHP-powered webpage and embedding it into your Blogger site. Additionally, some third-party services provide tools and widgets that can generate dynamic content without server-side scripting.

You can include their embeddable code snippets in your Blogger posts or pages to incorporate interactive elements or forms.

Even though Blogger doesn’t directly support PHP scripting, these workarounds allow you to add dynamic functionality to your blog, enhancing engagement and interactivity.
