I suggest you echo the query to see whether it is what you are expecting. Modifiy the part where you construct the query like this:

// put the query in a variable
$q = "UPDATE books SET Title ='$title_save', Price ='$price_save', Stock='$stock_save' WHERE Code= '$code'";

// submit query using the variable
mysql_query($q) or die(mysql_error(); 

// add this to display the query
die($q);

Now you will be able to see if the query gets constructed OK and you can copy it to phpmyadmin or mysql client and test it.

Two other notes:

  1. your form has no </form> tag. It should be after </table> tag.
  2. your form is missing an action attribute (I think it is required)
