How to keep pop up open and after running php script
<p>HI i am developing my website and want my login forms to be on pop up windows, as i am stuck because my pop get closed after running my php script on the pop window. due to which i am unable to echo error messages on the same popup (like incorrect password and user already exists).</p>
