I have a form which is developed in php with captcha. Problem is when the captcha is wrong the form data which user entered is losing, which I don't want. I want to store the form data when the captcha is wrong. Thanks in advance.

It depends what the captcha is doing. If you get to the "action" page for your form before the captcha is verified, then you can save the variables into Session variables or make them hidden variables attached to a "Back" button to go back to your form.
