title: Is this sql request correct?
body: <p>I've been having some problems with Ajax+php registration lately.
  I ultimately came to the conclusion that the root of all problems would be somewhere in the sql request. Can anyone please take a look at it?</p>
  
  <pre><code>$insert_new_user=mysql_query("INSERT INTO users (fname,lname,email,password,age,sex,city,timereg,frcode) VALUES('$fname_received','$lname_received','$email_received','$password_received','$dob_received','$sex_received','$city_received,'$timepassreg','$frcode')");
  </code></pre>
