title: how to prevent html form reset if submit is unsuccessful
body: <p>I am using a form to register the user on my website and i have a captcha security on it. Everything is working well and good but the only problem that i am facing is that if i enter a wrong captcha or somehow the page refreshes , all the data entered by the user is wiped out.</p>
  
  <p>what i wish to achieve is that even if the captcha entered is wrong and the form is submitted , the form should have all the fields intact as the user filled in excluding the captcha field.</p>
  
  <p>How can this be done? My form is html and the processing page is php</p>
