Question: php multiple database field update
Answer: Aside from not using mysql_ functions, it seems all you need are some backticks. I would also recommend you explicitly define the column name before hand. You should turn on error reporting as it will help you figure out where you issues are coming from. At the least, echo $Query;.

for($i=1; $i&lt;9; $i++) {
    if($weekInfo == "week". $i) {
        $columnName = 'd' . $i;

        $Query="UPDATE db.table SET `$columnName` = '" .addslashes($d1). "', weekInfo='" .addslashes($weekInfo). "' WHERE uid='".addslashes($uid)."'";
        $result = mysql_query($Query);
    }
}
