I installed a plugin (Delete My Account) which lets me place a hyperlink anywhere inside an article or module, which when clicked, deletes the account of the registered user from the front-end. What i want is to trigger a captcha verification pop-up box (or something like that) whenever that hyperlink is clicked & the user should only be able to access that hyperlink when he inputs the captcha verification correctly. Is there a way out?
Showing re-captcha before deleting user's account will be a complex task.
If you can customize the code, here is an suggestion, which can be fruitful for you.
An extra text box can be displayed in which user can fill the text string. This value can be any mathematics calculation or any pattern of string. You need to store the expected value in session so that you can verify it later.
Hope it helps you.
