  1. shouldn't spaces between dollar sign , php variable name.
  2. if column name has space in it, enclose column names properly
  3. do not use mysql_* function. they're deprecated , no longer maintained. use mysqli or pdo.
  4. you're sql statement has sql injection. use mysql_real_escape_string or pdo.
