Attach dynamic image in mail in codeignitor

In CodeIgniter, you can attach a dynamic image to an email using the email library. Here's an example of how you can do it:

Step 1: Create the image

First, you need to create the dynamic image. You can use a library like GD or ImageMagick to generate the image dynamically. For example, let's say you want to generate an image with a random text:

$image_path = 'path/to/image.jpg';
$image_text = 'Hello, World!';

// Create the image
$image = imagecreate(200, 100);
imagestring($image, 4, 10, 10, $image_text, imagecolorallocate($image, 255, 255, 255));
imagejpeg($image, $image_path);
imagedestroy($image);

Step 2: Attach the image to the email

Now, you need to attach the image to the email using the email library. You can do this by creating a new instance of the CI_Email class and using the attach() method:

$email = &get_instance()->email;

// Set the email settings
$email->from('[email protected]', 'Your Name');
$email->to('[email protected]');
$email->subject('Dynamic Image Email');

// Attach the image
$image_data = file_get_contents($image_path);
$email->attach($image_path, 'image/jpeg', 'dynamic_image.jpg', $image_data);

// Send the email
$email->send();

In this example, we're using the file_get_contents() function to read the contents of the image file and passing it to the attach() method along with the image path, MIME type, and file name.

Note: Make sure to replace the path/to/image.jpg with the actual path to your image file.

That's it! With these steps, you should be able to attach a dynamic image to an email using CodeIgniter.
