Verification Image passed back through AJAX call

[KDawg44]

Hi,

I would like a verification image for new sign ups on a website. Is
there a way to call the PHP script through an AJAX call and have the
image passed back and then display? Is there a way to pass the image
serialized back to the browser and then displayed? (or something like
that?)

I know that I do not need to do it this way but I am wondering if its
possible.

Thanks.

Kevin

If you're using PHP to dynamically generate the image, using GD or
something, you simply access the script as a normal image. Requesting
the image itself shouldn't necessitate an asynchronous request. If you
want to use "ajax", you might consider sending the user's code for
validation via the request object.

There is no reason to use a captcha for user-verification! Its one of
the badest way to solve it.

I know, a lot of websites use it, but it makes the website/registration
unaccessible for users with disabilities. So it results in a
usability-problem. Blind or visually impaired users must use the same
technique as bots for solving a registration.

Using of captchas is a mark of lowlevel knowlegde for the
userinterface-programmer!

A lot of techniques can solve youre problem by a better way.

- Double-Op-IN
- Random or untypcaly Formfieldnames
- Checking Input by a lot of effective checking-methods
- and much more

The Web contains a lot of proposals for handling registrations. You only
have to sensible combine then!

So long, Ulf

Ajax is overkill - just request a new image bound to the session using
javascript:

document.getEle mentById("ImgTa gPreviouslyPlac edOnPage").src= "http://
example.com/capcha.php";
