Upload base64 string image

Question

I have a plugin which crops my image and sends back a base64 data that looks like this: data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQ... . How can I upload this returned image via file upload field in my form to my server?

PS: In short I want to automaticly add returned image to my file input field of my form.

Answer 1

The same way you upload any other string to your server. The fact that the string is Base64 doesn't change anything.

You can put it in an <input type="hidden"> , then use PHP code to decode the Base64 and save the bytes somewhere.

Answer 2

使用此代码

$image =chunk_split( base64_encode(file_get_contents($_FILES['image_name']['tmp_name'])));
