Question

How would I write a MySQL error to a file instead of displaying it to the user?

here is what I have so far…

if (!mysql_query($sql_query,$connection))
  {
  die('Error: ' . mysql_error());
  }
echo "Success!";

You can use the error_log function in php for that.

error_log("You messed up!", 3, "/var/tmp/my-errors.log");

Edit: so in your case this would look like the following (although i would use a different if statement)

if (!mysql_query($sql_query,$connection))
{
    error_log(mysql_error() . "\n", 3, "/var/tmp/my-errors.log");
}
echo "Success!";
