Hello, i am thinking to add a registration directly from my app using WWWForm, but i have a doubt:
If i want to use a captcha, first i have to download the registration url and get the captcha picture and use it on unity, but if i am correct, this constructor WWW(string url, WWWForm form); download the page and send the form at the same time… but i want to:
Download page → get picture → use picture as sprite → make a unity UI form to register → user to fill that form → send the form to the website after pressing a button… But how can i send back the correct captcha if you have to send the form at the same time u download the page?
My only option could be to create a page to send the captcha and a hash key to unity, a SQL table to store the captcha string, the hash key assigned and a timestamp to remove after 10 minuts, then the user fill the registration form with the captcha, send the form to another page that check the database hash key and his captcha. Is there a better way? i am missing something?
