Question

I have created a custom product configurator that saves a canvas element as a base64 encoded image. When I echo the image in the browser as the image src it works fine.

So something like this works:

$base64Image = $_POST['dataUrl'];
echo '<img src="'.$base64Image.'" />';

My problem is that codeigniter wont add this base64 image src to the session, probably because its too big. I have tried some methods that people have used to write an image to the server and they all throw errors. Does anyone know how I can write this base64 string to an image on the server like ‘myimage.png’ in the images/custom folder?

Any help is appreciated.

You can also use

$decoded=base64_decode($base64Image);
file_put_contents('newImage.JPG',$decoded);
