I’ve created a code to change a password. Now it seem contain an error. When I fill in the form to change password, and click save the error message:

You forgot enter your user id!
Please try again.

I really don’t know what the error message means. Please guys. Help me fix it.

Here’s is the code:

 You forgot enter your userid!
';
 }else{
  $u=escape_data($_POST['userid']);
 }

 //check for existing password
 if(empty($_POST['password'])){
  $p=FALSE;
  $message .='
You forgot to enter your existing password!
';
 }else{
  $p=escape_data($_POST['password']);
 }

 //check for a password and match againts the comfirmed password.
 if(empty($_POST['password1'])) {
  $np=FALSE;
  $message .='
 you forgot to enter your new password!
';
 }else{
  if($_POST['password1'] == $_POST['password2']){
  $np=escape_data($_POST['password1']);
 }else{
  $np=FALSE;
  $message .='
 your new password did not match the confirmed new password!
';
 }
}
