Question

I was wondering if there was a way of running PHP when an input is changed, the input is question is:

<input id="custom_file_upload" type="file" name="Filedata" />

I was thinking prehaps using some jQuery or AJAX to run an external file when changed?

Any help would be appreciated,

Thanks!

http://api.jquery.com/change/

mixed with

http://api.jquery.com/jQuery.post/

Great example of this idea can be seen in some examples here: http://jquery.bassistance.de/validate/demo/

Usernames and emails are validated against a script, to make sure they do not already exist in the DB.
