In the world of digital interactions, QR codes have become indispensable for businesses and individuals. Whether sharing a URL, embedding text, or providing contactless payment options, QR codes provide a seamless way to bridge the physical and digital realms. In this guide, we’ll explore how to generate dynamic QR code using PHP, helping you create a valuable feature for your website.
Why Use QR Codes on Your Website?
QR codes offer many benefits, including:
- User Convenience: Access URLs or information instantly by scanning with a smartphone.
- Versatility: Share websites, text, contact information and more.
- Professional Appeal: A well-implemented QR code generator showcases the best design and development on your platform.
Integrating QR code generation with PHP is an essential skill for developers. This allows dynamic customization of QR codes based on user input, creating personalized experiences.
Getting Started with QR Code Generation in PHP
To create a dynamic QR code generator, you will need:
- PHP Server: Make sure your development environment is PHP-enabled.
- PHP QR Code Library: Use a library like
phpqrcodeto simplify QR code creation. - Bootstrap Framework: Enhance your designs with responsive UI.
Installing the PHP QR Code Library
Download the phpqrcode library and place it in your project folder. This lightweight library provides functions to generate QR codes in a variety of formats.
Building the QR Code Generator Interface
Let’s create an intuitive user interface using HTML and Bootstrap. This layout ensures that visitors can input their data and generate the QR code with ease. Below is the HTML structure:
<div class="container mt-5">
<div class="row justify-content-center">
<div class="col-lg-6">
<div class="panel panel-primary">
<div class="panel-heading bg-primary text-white p-3">
<h4 class="text-white font-weight-bold">Enter Information to Generate QR Code</h4>
</div>
<div class="panel-body p-3">
<form method="post" action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']); ?>">
<div class="form-group">
<label for="item_id" class="text-white font-weight-bold">Add TEXT, URL or QRCODE</label>
<input type="text" id="item_id" name="item_id" class="form-control" placeholder="Enter URL or Text" required />
</div>
<button type="submit" class="btn btn-primary" style="margin: 5px;">
Generate QR Code
</button>
</form>
</div>
</div>
</div>
</div>
</div>
This layout allows users to input text or URLs while ensuring a clean and responsive design.
PHP Code to Dynamically Generate QR Codes
The PHP script processes the user input and generates the QR code using the phpqrcode library. Here is the PHP logic:
require_once 'phpqrcode/qrlib.php';
if (isset($_POST['item_id'])) {
$item_id = htmlspecialchars($_POST["item_id"]);
$file = 'image/qr1.png';
$ecc = 'H';
$pixel_size = 10;
$frame_size = 3;
if (!file_exists('image')) {
mkdir('image', 0777, true);
}
QRcode::png($item_id, $file, $ecc, $pixel_size, $frame_size);
echo "<div class='mt-4'>";
echo "<h3>Generated QR Code for: <span class='text-white'>{$item_id}</span></h3>";
echo "<img src='{$file}' width='550' alt='Generated QR Code'>";
echo "</div>";
}
Key Features of the Script
- Error Correction: The
$eccparameter ensures QR code readability. - Dynamic Input: Generates QR codes based on user-supplied text or URL.
- File Storage: Saves the generated QR code in a folder for reuse or download.
Integrating design and development for a seamless experience
