Hi ya'll,

 

I am lost as to why I am getting this error in my script. Can anyone kindly
explain why this is so.

 

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result
resource in /home/cm/public_html/cell/login.php

if($_POST['submit'] == '>Log In')

{

            $user=$_POST["email"];

            $pass=$_POST["pass"];

            $sql_query = mysql_query("SELECT * FROM cm_customer WHERE
emial='$user'");

            $sql_query = mysql_num_rows($sql_query);

 

            if (($sql_query) >0)

                                    $valid = $user;

                                    session_start();

                                    session_register("valid");

}

}

 

  if (session_is_registered("reg"))

  {

              echo "ok";

  }

 

  else

  {

     echo "sorry";
