Entity Form > Anonymous > Once submitted > Restrict resubmit on form reload

Hello,

I have developed an entity form for anonymous users. When user fills out form and clicks on submit, I just display "Thank you" message on the same page and hide entity form.

1. How to expire session once submitted?

2. On "Thank you" message, when I reload the page, it RESUBMITS the record with the same information. This is the main problem.

How can I solve this? When -

Entity form doesn't have "New session on form load" setting like Web Form.
I cannot even set Session Timeout under Site settings as it is anonymous form.
Don't want to redirect to another page due to licensing cost.
Clear all the fields on Submit???

Please suggest.

Thank you.

Most effective way is to redirect to another page (and is what you typically may do on a normal portal).

Apart from that you would probably have to hook up some JavaScript such as
if ( window.history.replaceState ) { window.history.replaceState( null, null, window.location.href ); }

And trigger it on something - possibly if the message is on the page (hint: it the message span has an id).

Or find the form data and clear it.
