Question

When a teamname is not in the database I want to enter it if not ignore it. But I do not get an error all I see is the echoed statement but it is not entered into the database.
The database is MySQL and table name is 2012FallTeamstats I have a team_id column which is autoincremented a win a loses and a percentages field. (4 total in table)

mysql_query("SELECT teamname FROM 2012FallTeamstats WHERE teamname = '$teamH'"); 
if (mysql_affected_rows() == 0) {
    mysql_query("INSERT INTO 2012FallTeamstats (teamname) VALUES ('$teamH')");
    echo "New: <strong>".stripslashes($teamH)."</strong> (home team) inserted into the database.<br>";
}

Answer 1

try mysql_num_rows() instead of mysql_affected_rows.

code like this.

$result_team =  mysql_query(.........); (your code)

then

if(mysql_num_rows($result_team) == 0)
{
//insert command
}
