All,
I have an HTML page that contains a form.
When the user completes the form and clicks "Submit" - the form posts the user's inputs to a PHP page.
That PHP page processes the inputs and returns the user's results as an attachment.
So far - everything works OK - the user clicks "Submit", the browser's progress bar starts to "spin", and after a few seconds, the attachment is downloaded.
However, in the browser - the user is still on the form page. That's OK with me.
So - here's my question. Ideally, when the user clicks "Submit" - I would like to update the form page to indicate that the "process" is in progress. E.g.,
- disable the submit button to prevent redundant clicks
- display a "downloading" message and a "spinner"-type graphic
Then, when the download is complete - I'd like to capture that event so that I could re-enable the submit button and remove the downloading message.
Is this possible?
Or - is my initial set-up just wrong? Is there a better way to do this? (That is - have a form that calls a PHP page, have the PHP page return an attachment, and then return control to the calling page?)
Thanks in advance for your advice and insight!
