I need to create a page with a survey, an embedded from somewhere, but I need this page to be accessed only once per user... I need the form submission to be anonymous, but to save in the DB a flag that this user has already accessed this page.
can anyone help me with the PHP code to insert in a table that I create for this purpose, and the verification (select) to check if the user has already submitted it?
I would like to have the insertion when the user presses the submit button on the form... is it possible with an embedded code?
Thanks in advance for any help that you might give me..
