Is it possible to post variables to another site without having the visitor click a submit button.
Here is what my thought is
I have a form, and I want to check that all required fields have been filled out, and that the information within those fields are not jibberish before sending the information to another site, plus, the initial form will have a file field for uploading a file to my server, but, the tempfile should not be moved to a permanant directory until after the visitor has submitted the form and returned from the other site, but I still need to pass the tempfile's temp_name to the other site, so that information can be returned when the visitor returns to the site.
One reason I would like to do this in one step instead of two is to simplify things for the visitor, the other is that I do not want that certain information that would be included in hidden fields to be viewable to the visitor by looking at the page's source code.
I have been looking around, trying to find information about doing such a thing, without having to bother anyone, but am not having much luck. So, I figured I could ask and if it isn't possible than I do not have to waste any more time looking.
Anyway, thanks for the help either way...
