      It is normal practice to store user log-in details in a database.
      Where at least the password is encrypted.
      But this is not much use with Javascript.

      Are you asking how to do this in php?
      You will need some understanding of php to attempt this.

          if it is easy to do it from client side(validation ) tell me in javascript.i have enclosed my database coding that is the insertion of fields of the user(insertuser .php).the previous code was the form where the user registers himself(createu ser.php).kindly check out and resolve in this very simple manner as i m a beginner for php.and the username should not be repeated.

          [code=php]

          <?php
          include 'menu.php';
          include 'connect.php';
          ?>
          <table border="0" cellpadding="0" cellspacing="0" >

          <tr>
          <td>

              I can't write your code for you.

              But the general idea is to collect all user log in details from a HTML form.
              Then query the database to find a matching username and password.
              If the query returns a record then the login is successful.
              Otherwise report a problem to the user.

              This is pretty basic SQL/PHP but cannot be done in Javascript.

                  If I'm understanding the OP correctly, he is looking for a way to match the password and the confirmation password, not to actually log the user in.
                  Am I right?

                  If so, all you would have to do is add a extra else if statement to your existing if statements in the JavaScript you posted, to match the "cconfirmpw d" variable to the "cpwd" variable, and return false if they don't match.

                      And to compare the values, it's as simple as

                      Code:
                      if ( $val1 === $val2 )
{
    // They match.
}
else
{
    // The don't.
}
