Prerequisites

Before we dive into the implementation process, ensure you have the following requirements checked:

Basic understanding of PHP and HTML
FilamentPHP framework installed on your system
A webcam connected to your system (obviously!)
A code editor or IDE of your choice

Step 1: Setting up the Project Structure

Let’s create a new FilamentPHP project. Open your terminal/command prompt and run the following command:

composer create-project filament-php/framework my-webcam-project

This will create a new FilamentPHP project named “my-webcam-project”. Navigate into the project directory:

cd my-webcam-project

Create a new directory named “resources” within the project root. This is where we’ll store our HTML, CSS, and JavaScript files:

mkdir resources

Step 2: Creating the Input Form HTML

Create a new file named “index.html” within the “resources” directory:

touch resources/index.html

Open “index.html” in your code editor and add the following HTML code:

<!DOCTYPE html>
<html>
<head>
    <title>Webcam Input Form</title>
    <script src="https://cdn.jsdelivr.net/npm/@filament-php/[email protected]/dist/filament.min.js"></script>
</head>
<body>
    <h1>Webcam Input Form</h1>
    <form id="webcam-form">
        <label>Name:</label>
        <input type="text" id="name" name="name"><br><br>
        <label>Webcam Capture:</label>
        <video id="webcam-video"></video>
        <button id="capture-button">Capture</button>
        <input type="hidden" id="captured-image" name="captured-image">
    </form>
</body>
</html>

This HTML code creates a basic input form with a text field for the user’s name, a video element for displaying the webcam feed, a capture button, and a hidden input field to store the captured image.

Step 3: Implementing Webcam Integration using JavaScript

Create a new file named “script.js” within the “resources” directory:

touch resources/script.js

Open “script.js” in your code editor and add the following JavaScript code:

const webcamForm = document.getElementById('webcam-form');
const webcamVideo = document.getElementById('webcam-video');
const captureButton = document.getElementById('capture-button');
const capturedImageInput = document.getElementById('captured-image');

// Request access to the webcam
navigator.mediaDevices.getUserMedia({ video: true, audio: false })
    .then(stream => {
        webcamVideo.srcObject = stream;
        webcamVideo.play();
    })
    .catch(error => {
        console.error('Error accessing webcam:', error);
    });

// Capture image on button click
captureButton.addEventListener('click', () => {
    const canvas = document.createElement('canvas');
    canvas.width = webcamVideo.videoWidth;
    canvas.height = webcamVideo.videoHeight;
    const ctx = canvas.getContext('2d');
    ctx.drawImage(webcamVideo, 0, 0, canvas.width, canvas.height);

    const imageDataURL = canvas.toDataURL();
    capturedImageInput.value = imageDataURL;
});

This JavaScript code requests access to the user’s webcam, displays the webcam feed in the video element, and captures an image when the capture button is clicked. The captured image is then stored in the hidden input field as a data URL.

Step 4: Handling Form Submission in FilamentPHP

Create a new file named “WebcamFormController.php” within the “app/Http/Controllers” directory:

touch app/Http/Controllers/WebcamFormController.php

Open “WebcamFormController.php” in your code editor and add the following PHP code:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class WebcamFormController extends Controller
{
    public function handleSubmit(Request $request)
    {
        $name = $request->input('name');
        $capturedImage = $request->input('captured-image');

        // Store the captured image in a database or perform further processing
        // ...

        return redirect()->route('success');
    }
}

This PHP code defines a controller that handles the form submission, retrieves the captured image from the request, and performs further processing (in this example, we’re simply redirecting to a success route).

Step 5: Defining Routes in FilamentPHP

Open the “routes.web.php” file within the “app/Http” directory:

touch app/Http/routes.web.php

Add the following route definitions:

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\WebcamFormController;

Route::get('/', function () {
    return view('index');
});

Route::post('/submit', [WebcamFormController::class, 'handleSubmit'])->name('submit');
Route::get('/success', function () {
    return 'Form submitted successfully!';
})->name('success');

These route definitions map the form submission to the `handleSubmit` method in the `WebcamFormController` and define a success route that displays a success message.

Conclusion

That’s it! You’ve successfully implemented an input form with webcam integration in FilamentPHP framework. Run the project using the following command:

php artisan serve

Open a web browser and navigate to http://localhost:8000. You should see the input form with a webcam feed. Click the capture button to capture an image, and submit the form to see the captured image stored in the request.

Troubleshooting Tips

If you encounter issues with webcam access or image capture, ensure that:

Your webcam is properly connected and configured
You have granted access to the webcam in your browser’s settings
The JavaScript code is executed in a secure context (HTTPS)
