Comprehensive PHP web application

Creating a comprehensive PHP web application that includes HTML forms, contact functionalities, database management (CRUD operations), data processing, and mailing features is an excellent project to share with your followers. Below is a step-by-step procedure to guide you through building such an application. This guide assumes you have a basic understanding of HTML, CSS, and PHP. Let’s dive in!

---

Project Overview

We’ll build a Simple Contact Management System with the following features:

1. Contact Form: Allow users to submit their contact information.
2. Admin Dashboard: View, add, edit, and delete contacts.
3. Mailing Functionality: Send confirmation emails to users upon form submission.
4. Data Processing: Validate and sanitize user inputs.
5. Security Measures: Protect against common web vulnerabilities.

---

Prerequisites

Before we begin, ensure you have the following installed on your development machine:

• Web Server: Apache or Nginx
• PHP: Version 7.4 or higher
• MySQL: For database management
• Code Editor: VS Code, Sublime Text, PHPStorm, etc.
• Composer: Dependency management (optional but recommended)

For simplicity, we’ll use XAMPP as it bundles Apache, MySQL, and PHP.

---

1. Setting Up the Development Environment

a. Install XAMPP

1. Download XAMPP:
   • Download XAMPP for your operating system.
2. Install XAMPP:
   • Follow the installation wizard and install it in the default directory.
3. Start Apache and MySQL:
   • Open the XAMPP Control Panel.
   • Start the Apache and MySQL modules.

b. Configure PHP

1. Enable Necessary Extensions:
   • Open php.ini file located in xampp/php/php.ini.
   • Ensure the following extensions are enabled (uncomment if necessary): extension=mysqli extension=pdo_mysql extension=openssl
2. Restart Apache:
   • After making changes, restart Apache from the XAMPP Control Panel.

---

2. Creating the Database

a. Access phpMyAdmin

1. Open your browser and navigate to http://localhost/phpmyadmin/.

b. Create a New Database

1. Click on “New” in the left sidebar.
2. Enter the database name, e.g., contact_manager.
3. Choose “utf8mb4_unicode_ci” as the collation for better Unicode support.
4. Click “Create”.

c. Create a contacts Table

1. Select the contact_manager database.
2. Click on “New” to create a table.
3. Define the table structure as follows:

Field	Type	Null	Key	Default	Extra
id	INT	NO	PRI	NULL	AUTO_INCREMENT
name	VARCHAR(100)	NO		NULL
email	VARCHAR(100)	NO		NULL
subject	VARCHAR(150)	NO		NULL
message	TEXT	NO		NULL
submitted_at	TIMESTAMP	NO		CURRENT_TIMESTAMP

3. Click “Save” to create the table.

3. Project Structure

Organize your project files for better maintainability. Here’s a suggested structure:

contact-manager/
├── assets/
│   ├── css/
│   │   └── styles.css
│   └── js/
│       └── scripts.js
├── config/
│   └── db.php
├── templates/
│   ├── header.php
│   └── footer.php
├── admin/
│   ├── index.php
│   ├── add.php
│   ├── edit.php
│   └── delete.php
├── contact.php
├── send_mail.php
└── README.md

---

4. Configuration

a. Database Connection (config/db.php)

Create a file named db.php inside the config directory to handle database connections.

<?php
// config/db.php

$host = 'localhost';
$db   = 'contact_manager';
$user = 'root'; // Default XAMPP MySQL user
$pass = '';     // Default XAMPP MySQL password is empty
$charset = 'utf8mb4';

$dsn = "mysql:host=$host;dbname=$db;charset=$charset";

$options = [
    PDO::ATTR_ERRMODE            => PDO::ERRMODE_EXCEPTION, // Enable exceptions
    PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,       // Fetch associative arrays
    PDO::ATTR_EMULATE_PREPARES   => false,                  // Disable emulation
];

try {
    $pdo = new PDO($dsn, $user, $pass, $options);
} catch (\PDOException $e) {
    // Handle connection errors
    throw new \PDOException($e->getMessage(), (int)$e->getCode());
}
?>

---

5. Creating Reusable Templates

To maintain consistency and avoid code duplication, create reusable header and footer templates.

a. Header (templates/header.php)

<?php
// templates/header.php
?>
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Contact Management System</title>
    <link rel="stylesheet" href="/contact-manager/assets/css/styles.css">
</head>
<body>
    <header>
        <h1>Contact Management System</h1>
        <nav>
            <a href="/contact-manager/admin/index.php">Admin Dashboard</a>
            <a href="/contact-manager/contact.php">Contact Us</a>
        </nav>
    </header>
    <main>

b. Footer (templates/footer.php)

<?php
// templates/footer.php
?>
    </main>
    <footer>
        <p>&copy; <?php echo date("Y"); ?> Your Company Name</p>
    </footer>
    <script src="/contact-manager/assets/js/scripts.js"></script>
</body>
</html>

---

6. Building the Contact Form

a. Contact Form Page (contact.php)

This page allows users to submit their contact information.

<?php
// contact.php

require 'config/db.php';
require 'templates/header.php';

$errors = [];
$success = '';

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // Sanitize and validate inputs
    $name = trim($_POST['name']);
    $email = trim($_POST['email']);
    $subject = trim($_POST['subject']);
    $message = trim($_POST['message']);

    // Basic validation
    if (empty($name)) {
        $errors[] = 'Name is required.';
    }

    if (empty($email)) {
        $errors[] = 'Email is required.';
    } elseif (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
        $errors[] = 'Invalid email format.';
    }

    if (empty($subject)) {
        $errors[] = 'Subject is required.';
    }

    if (empty($message)) {
        $errors[] = 'Message is required.';
    }

    if (empty($errors)) {
        // Insert into database
        $stmt = $pdo->prepare('INSERT INTO contacts (name, email, subject, message) VALUES (?, ?, ?, ?)');
        if ($stmt->execute([$name, $email, $subject, $message])) {
            // Send confirmation email
            $to = $email;
            $email_subject = "Thank you for contacting us!";
            $email_body = "Hi $name,\n\nThank you for reaching out. We have received your message and will get back to you shortly.\n\nBest Regards,\nYour Company Name";
            $headers = "From: no-reply@yourdomain.com\r\n";

            if (mail($to, $email_subject, $email_body, $headers)) {
                $success = 'Your message has been sent successfully!';
            } else {
                $success = 'Your message was saved, but we could not send a confirmation email.';
            }

            // Clear form fields
            $name = $email = $subject = $message = '';
        } else {
            $errors[] = 'There was an error saving your message. Please try again.';
        }
    }
}
?>

<h2>Contact Us</h2>

<?php if (!empty($errors)): ?>
    <div class="error">
        <ul>
            <?php foreach($errors as $error): ?>
                <li><?php echo htmlspecialchars($error); ?></li>
            <?php endforeach; ?>
        </ul>
    </div>
<?php endif; ?>

<?php if ($success): ?>
    <div class="success">
        <p><?php echo htmlspecialchars($success); ?></p>
    </div>
<?php endif; ?>

<form action="contact.php" method="POST">
    <label for="name">Name:</label>
    <input type="text" id="name" name="name" value="<?php echo htmlspecialchars($name ?? ''); ?>" required>

    <label for="email">Email:</label>
    <input type="email" id="email" name="email" value="<?php echo htmlspecialchars($email ?? ''); ?>" required>

    <label for="subject">Subject:</label>
    <input type="text" id="subject" name="subject" value="<?php echo htmlspecialchars($subject ?? ''); ?>" required>

    <label for="message">Message:</label>
    <textarea id="message" name="message" required><?php echo htmlspecialchars($message ?? ''); ?></textarea>

    <button type="submit">Send Message</button>
</form>

<?php
require 'templates/footer.php';
?>

b. Styling the Form (assets/css/styles.css)

Add basic styles to make the form look presentable.

/* assets/css/styles.css */

body {
    font-family: Arial, sans-serif;
    margin: 0;
    padding: 0;
}

header, footer {
    background-color: #333;
    color: #fff;
    padding: 10px 20px;
}

header h1, footer p {
    margin: 0;
}

nav a {
    color: #fff;
    margin-right: 15px;
    text-decoration: none;
}

main {
    padding: 20px;
}

form {
    max-width: 600px;
    margin: auto;
}

label {
    display: block;
    margin-top: 15px;
}

input[type="text"],
input[type="email"],
textarea {
    width: 100%;
    padding: 8px;
    margin-top: 5px;
    box-sizing: border-box;
}

button {
    margin-top: 15px;
    padding: 10px 20px;
}

.error {
    background-color: #f2dede;
    color: #a94442;
    padding: 15px;
    margin-bottom: 20px;
    border: 1px solid #ebccd1;
    border-radius: 4px;
}

.success {
    background-color: #dff0d8;
    color: #3c763d;
    padding: 15px;
    margin-bottom: 20px;
    border: 1px solid #d6e9c6;
    border-radius: 4px;
}

---

7. Admin Dashboard

a. Admin Authentication (Optional but Recommended)

For simplicity, we’ll skip implementing user authentication in this guide. However, it’s highly recommended to protect your admin dashboard with authentication to prevent unauthorized access.

b. Admin Dashboard (admin/index.php)

This page displays all contacts and provides options to add, edit, or delete them.

<?php
// admin/index.php

require '../config/db.php';
require '../templates/header.php';

// Fetch all contacts
$stmt = $pdo->query('SELECT * FROM contacts ORDER BY submitted_at DESC');
$contacts = $stmt->fetchAll();
?>

<h2>Admin Dashboard</h2>

<a href="add.php">Add New Contact</a>

<table>
    <thead>
        <tr>
            <th>ID</th>
            <th>Name</th>
            <th>Email</th>
            <th>Subject</th>
            <th>Message</th>
            <th>Submitted At</th>
            <th>Actions</th>
        </tr>
    </thead>
    <tbody>
    <?php if ($contacts): ?>
        <?php foreach ($contacts as $contact): ?>
            <tr>
                <td><?php echo htmlspecialchars($contact['id']); ?></td>
                <td><?php echo htmlspecialchars($contact['name']); ?></td>
                <td><?php echo htmlspecialchars($contact['email']); ?></td>
                <td><?php echo htmlspecialchars($contact['subject']); ?></td>
                <td><?php echo nl2br(htmlspecialchars($contact['message'])); ?></td>
                <td><?php echo htmlspecialchars($contact['submitted_at']); ?></td>
                <td>
                    <a href="edit.php?id=<?php echo $contact['id']; ?>">Edit</a> |
                    <a href="delete.php?id=<?php echo $contact['id']; ?>" onclick="return confirm('Are you sure you want to delete this contact?');">Delete</a>
                </td>
            </tr>
        <?php endforeach; ?>
    <?php else: ?>
        <tr>
            <td colspan="7">No contacts found.</td>
        </tr>
    <?php endif; ?>
    </tbody>
</table>

<?php
require '../templates/footer.php';
?>

c. Adding New Contacts (admin/add.php)

This page allows the admin to manually add a new contact.

<?php
// admin/add.php

require '../config/db.php';
require '../templates/header.php';

$errors = [];
$success = '';

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // Sanitize and validate inputs
    $name = trim($_POST['name']);
    $email = trim($_POST['email']);
    $subject = trim($_POST['subject']);
    $message = trim($_POST['message']);

    // Basic validation
    if (empty($name)) {
        $errors[] = 'Name is required.';
    }

    if (empty($email)) {
        $errors[] = 'Email is required.';
    } elseif (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
        $errors[] = 'Invalid email format.';
    }

    if (empty($subject)) {
        $errors[] = 'Subject is required.';
    }

    if (empty($message)) {
        $errors[] = 'Message is required.';
    }

    if (empty($errors)) {
        // Insert into database
        $stmt = $pdo->prepare('INSERT INTO contacts (name, email, subject, message) VALUES (?, ?, ?, ?)');
        if ($stmt->execute([$name, $email, $subject, $message])) {
            $success = 'New contact added successfully.';
            // Clear form fields
            $name = $email = $subject = $message = '';
        } else {
            $errors[] = 'There was an error adding the contact. Please try again.';
        }
    }
}
?>

<h2>Add New Contact</h2>

<?php if (!empty($errors)): ?>
    <div class="error">
        <ul>
            <?php foreach($errors as $error): ?>
                <li><?php echo htmlspecialchars($error); ?></li>
            <?php endforeach; ?>
        </ul>
    </div>
<?php endif; ?>

<?php if ($success): ?>
    <div class="success">
        <p><?php echo htmlspecialchars($success); ?></p>
    </div>
<?php endif; ?>

<form action="add.php" method="POST">
    <label for="name">Name:</label>
    <input type="text" id="name" name="name" value="<?php echo htmlspecialchars($name ?? ''); ?>" required>

    <label for="email">Email:</label>
    <input type="email" id="email" name="email" value="<?php echo htmlspecialchars($email ?? ''); ?>" required>

    <label for="subject">Subject:</label>
    <input type="text" id="subject" name="subject" value="<?php echo htmlspecialchars($subject ?? ''); ?>" required>

    <label for="message">Message:</label>
    <textarea id="message" name="message" required><?php echo htmlspecialchars($message ?? ''); ?></textarea>

    <button type="submit">Add Contact</button>
</form>

<?php
require '../templates/footer.php';
?>

d. Editing Contacts (admin/edit.php)

This page allows the admin to edit existing contacts.

<?php
// admin/edit.php

require '../config/db.php';
require '../templates/header.php';

$errors = [];
$success = '';

// Get contact ID from URL
$id = isset($_GET['id']) ? (int)$_GET['id'] : 0;

// Fetch existing contact
$stmt = $pdo->prepare('SELECT * FROM contacts WHERE id = ?');
$stmt->execute([$id]);
$contact = $stmt->fetch();

if (!$contact) {
    echo "<p>Contact not found.</p>";
    require '../templates/footer.php';
    exit;
}

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // Sanitize and validate inputs
    $name = trim($_POST['name']);
    $email = trim($_POST['email']);
    $subject = trim($_POST['subject']);
    $message = trim($_POST['message']);

    // Basic validation
    if (empty($name)) {
        $errors[] = 'Name is required.';
    }

    if (empty($email)) {
        $errors[] = 'Email is required.';
    } elseif (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
        $errors[] = 'Invalid email format.';
    }

    if (empty($subject)) {
        $errors[] = 'Subject is required.';
    }

    if (empty($message)) {
        $errors[] = 'Message is required.';
    }

    if (empty($errors)) {
        // Update in database
        $stmt = $pdo->prepare('UPDATE contacts SET name = ?, email = ?, subject = ?, message = ? WHERE id = ?');
        if ($stmt->execute([$name, $email, $subject, $message, $id])) {
            $success = 'Contact updated successfully.';
            // Refresh contact data
            $stmt = $pdo->prepare('SELECT * FROM contacts WHERE id = ?');
            $stmt->execute([$id]);
            $contact = $stmt->fetch();
        } else {
            $errors[] = 'There was an error updating the contact. Please try again.';
        }
    }
}
?>

<h2>Edit Contact</h2>

<?php if (!empty($errors)): ?>
    <div class="error">
        <ul>
            <?php foreach($errors as $error): ?>
                <li><?php echo htmlspecialchars($error); ?></li>
            <?php endforeach; ?>
        </ul>
    </div>
<?php endif; ?>

<?php if ($success): ?>
    <div class="success">
        <p><?php echo htmlspecialchars($success); ?></p>
    </div>
<?php endif; ?>

<form action="edit.php?id=<?php echo $id; ?>" method="POST">
    <label for="name">Name:</label>
    <input type="text" id="name" name="name" value="<?php echo htmlspecialchars($contact['name']); ?>" required>

    <label for="email">Email:</label>
    <input type="email" id="email" name="email" value="<?php echo htmlspecialchars($contact['email']); ?>" required>

    <label for="subject">Subject:</label>
    <input type="text" id="subject" name="subject" value="<?php echo htmlspecialchars($contact['subject']); ?>" required>

    <label for="message">Message:</label>
    <textarea id="message" name="message" required><?php echo htmlspecialchars($contact['message']); ?></textarea>

    <button type="submit">Update Contact</button>
</form>

<?php
require '../templates/footer.php';
?>

e. Deleting Contacts (admin/delete.php)

This script handles the deletion of contacts.

<?php
// admin/delete.php

require '../config/db.php';

// Get contact ID from URL
$id = isset($_GET['id']) ? (int)$_GET['id'] : 0;

// Delete contact
$stmt = $pdo->prepare('DELETE FROM contacts WHERE id = ?');
$stmt->execute([$id]);

// Redirect back to admin dashboard
header('Location: index.php');
exit;
?>

f. Styling the Admin Dashboard (assets/css/styles.css)

Add styles for the table and admin pages.

/* Add to assets/css/styles.css */

table {
    width: 100%;
    border-collapse: collapse;
    margin-top: 20px;
}

table, th, td {
    border: 1px solid #ddd;
}

th, td {
    padding: 12px;
    text-align: left;
}

th {
    background-color: #f4f4f4;
}

a {
    color: #007BFF;
    text-decoration: none;
}

a:hover {
    text-decoration: underline;
}

button {
    background-color: #28a745;
    color: #fff;
    border: none;
    cursor: pointer;
}

button:hover {
    background-color: #218838;
}

8. Mailing Functionality

We’ve already implemented basic mailing functionality in the contact form (contact.php). However, for more reliable and feature-rich mailing, it’s recommended to use a mailing library like PHPMailer.

a. Installing PHPMailer via Composer (Optional)

1. Initialize Composer:
   • Navigate to your project directory in the terminal.
   • Run composer init and follow the prompts.
2. Install PHPMailer: composer require phpmailer/phpmailer

b. Updating Mailing in contact.php

Here’s how you can integrate PHPMailer into your contact form for sending emails.

<?php
// contact.php (Updated mailing section)

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php'; // Composer's autoloader

// ... [rest of the code]

if (empty($errors)) {
    // Insert into database
    $stmt = $pdo->prepare('INSERT INTO contacts (name, email, subject, message) VALUES (?, ?, ?, ?)');
    if ($stmt->execute([$name, $email, $subject, $message])) {
        // Send confirmation email using PHPMailer
        $mail = new PHPMailer(true);

        try {
            // Server settings
            //$mail->SMTPDebug = SMTP::DEBUG_SERVER; // Enable verbose debug output
            $mail->isSMTP();                                            // Send using SMTP
            $mail->Host       = 'smtp.example.com';                     // Set the SMTP server
            $mail->SMTPAuth   = true;                                   // Enable SMTP authentication
            $mail->Username   = 'your_email@example.com';               // SMTP username
            $mail->Password   = 'your_email_password';                  // SMTP password
            $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;         // Enable TLS encryption
            $mail->Port       = 587;                                    // TCP port to connect to

            // Recipients
            $mail->setFrom('no-reply@yourdomain.com', 'Your Company');
            $mail->addAddress($email, $name);     // Add a recipient

            // Content
            $mail->isHTML(true);                                  // Set email format to HTML
            $mail->Subject = 'Thank you for contacting us!';
            $mail->Body    = "<p>Hi {$name},</p>
                              <p>Thank you for reaching out. We have received your message and will get back to you shortly.</p>
                              <p>Best Regards,<br>Your Company Name</p>";
            $mail->AltBody = "Hi {$name},\n\nThank you for reaching out. We have received your message and will get back to you shortly.\n\nBest Regards,\nYour Company Name";

            $mail->send();
            $success = 'Your message has been sent successfully!';
        } catch (Exception $e) {
            $success = 'Your message was saved, but we could not send a confirmation email.';
            // Log the error message: $mail->ErrorInfo
        }

        // Clear form fields
        $name = $email = $subject = $message = '';
    } else {
        $errors[] = 'There was an error saving your message. Please try again.';
    }
}
?>

Note:

• Replace 'smtp.example.com', 'your_email@example.com', and 'your_email_password' with your SMTP server details.
• Ensure that your hosting provider allows SMTP connections and that the credentials are correct.

9. Enhancing Security

a. Preventing SQL Injection

We’ve used prepared statements with PDO, which protects against SQL injection by separating SQL logic from data.

b. Cross-Site Scripting (XSS) Protection

• Sanitize Output: Use htmlspecialchars() when echoing user inputs to prevent XSS.
• Sanitize Inputs: Trim and validate all user inputs.

c. CSRF Protection

Implement Cross-Site Request Forgery (CSRF) tokens in forms to ensure that form submissions are genuine.

Example Implementation:

1. Generate CSRF Token: <?php // At the top of contact.php and admin forms session_start(); if (empty($_SESSION['csrf_token'])) { $_SESSION['csrf_token'] = bin2hex(random_bytes(32)); } ?>
2. Include CSRF Token in Forms: <input type="hidden" name="csrf_token" value="<?php echo $_SESSION['csrf_token']; ?>">
3. Validate CSRF Token on Form Submission: if ($_POST['csrf_token'] !== $_SESSION['csrf_token']) { $errors[] = 'Invalid CSRF token.'; }

d. Password Protecting Admin Pages

Implementing a simple authentication system or using HTTP Basic Authentication to protect the admin dashboard.

Simple HTTP Basic Authentication Example:

<?php
// At the top of admin/index.php, add the following:

$admin_user = 'admin';
$admin_pass = 'password123';

if (!isset($_SERVER['PHP_AUTH_USER']) || !isset($_SERVER['PHP_AUTH_PW']) ||
    $_SERVER['PHP_AUTH_USER'] !== $admin_user ||
    $_SERVER['PHP_AUTH_PW'] !== $admin_pass) {
    header('WWW-Authenticate: Basic realm="Admin Area"');
    header('HTTP/1.0 401 Unauthorized');
    echo 'Authentication required.';
    exit;
}
?>

Note:

• Replace 'admin' and 'password123' with secure credentials.
• For better security, implement a full authentication system with hashed passwords.

10. Testing the Application

1. Access the Contact Form:
   • Navigate to http://localhost/contact-manager/contact.php.
   • Fill in the form and submit. Check for the success message and confirmation email.
2. Access the Admin Dashboard:
   • Navigate to http://localhost/contact-manager/admin/index.php.
   • If using HTTP Basic Auth, enter the credentials.
   • View the submitted contacts, and try adding, editing, or deleting a contact.
3. Verify Database Entries:
   • Open phpMyAdmin and check the contacts table to ensure data is correctly stored.
4. Check Emails:
   • Ensure that confirmation emails are received. If using PHPMailer, verify SMTP settings if emails aren’t sent.

11. Deployment Considerations

When deploying your application to a live server, consider the following:

• Secure Database Credentials: Use environment variables or secure configuration methods to store sensitive information.
• Use HTTPS: Ensure your website uses HTTPS to encrypt data transmission.
• Regular Backups: Implement regular backups of your database and files.
• Error Reporting: Disable detailed error messages in production to prevent information leakage. // In production, set error reporting to minimal ini_set('display_errors', 0); ini_set('log_errors', 1);
• Update Dependencies: Keep PHP and all libraries updated to their latest versions to patch security vulnerabilities.

12. Further Enhancements

To make your application more robust and feature-rich, consider implementing the following:

1. User Authentication System:
   • Allow multiple admin users with different roles and permissions.
2. Pagination in Admin Dashboard:
   • Handle large numbers of contacts by paginating the list.
3. Search and Filter:
   • Enable searching and filtering of contacts based on criteria.
4. Export Contacts:
   • Provide options to export contacts in CSV or Excel formats.
5. Responsive Design:
   • Make the application mobile-friendly using responsive CSS frameworks like Bootstrap.
6. AJAX for Asynchronous Operations:
   • Improve user experience by handling form submissions and updates without full page reloads.
7. Logging and Monitoring:
   • Implement logging for activities and errors to monitor application health.
8. Unit Testing:
   • Write tests to ensure the reliability of your code.
