How to Create Custom Captcha Image in Laravel

In this tutorial we will learn how to create custom captcha image in Laravel.


How to create custom captcha image in Laravel

To create a custom Captcha image in Laravel, you can follow these steps:

Step 1 - Install the intervention/image package using Composer. This package provides a simple way to create and manipulate images in Laravel.

composer require intervention/image


Step 2 - Generate a Captcha code using PHP's rand() function.

$captcha = rand(1000, 9999);


Step 3 - Store the Captcha code in the session.

session()->put('captcha', $captcha);


Step 4 - Use the Intervention\Image\Facades\Image class to create a new image, and add the Captcha code as text to the image.

$image = Image::canvas(120, 40, '#ccc');
$image->text($captcha, 60, 20, function($font) {


Step 5 - Return the image as a response with the correct content type.

return response($image->encode('png'))
        ->header('Content-Type', 'image/png');


Step 6 - Add a route to your web.php file to handle requests for the Captcha image.

Route::get('/captcha', function () {
    // code to generate and return the Captcha image


Step 7 - Finally, add an HTML form to your view that includes the Captcha image and a field for the user to enter the code.

    <img src="/captcha" alt="Captcha Image">
    <input type="text" name="captcha">


Note: You may want to add additional security measures to your Captcha implementation, such as rate limiting or IP blocking for repeated incorrect attempts.
