"ALTER TABLE IF EXISTS user ADD top_game_sites INT( 1 ) NOT NULL");

To test if a column exists, you cna use the following query:
[sql]SHOW COLUMNS FROM <tablename> WHERE field = '<columnname>';[/sql]
Alternative you could disable error reporting and just run the query to add the column.

turn off error reporting:

PHP Code:


		
			
$db->reporterror = false;

$db->query_write(".....");

$db->reporterror = true;

The other option for first testing, i think you can figure that our yourself.
