$sql = mysql_query("SELECT firstname,Mobileno,City,Employee-Name FROM `clients` WHERE email = '$email'  AND code = '$code'");

Answer 1

Your question title says it all. Use OR instead of AND :

$sql = mysql_query("SELECT firstname,Mobileno,City,Employee-Name 
                    FROM `clients` 
                    WHERE email = '$email'  
                       OR code = '$code'")

OR means either email='$email' or code='$code' .

If you use AND both conditions should be satisfied.

Answer 2

as i know you want use one of email or code?

i think you should use this:

$sql = mysql_query("SELECT firstname,Mobileno,City,Employee-Name FROM `clients` WHERE email = '$email'  OR code = '$code'");

Answer 3

Use this code with OR condition.

$sql = mysql_query("SELECT firstname,Mobileno,City,Employee-Name 
                    FROM `clients` 
                    WHERE email = '.$email.'  
                       OR code = '.$code.'")
