    Question Using Select OnChange and Update Database

    I am having a little bit of a problem updating the database with the new value from the drop down box. For some reason it isn't receiving the value.



    $user = mysql_fetch_array(mysql_query("SELECT online,status,username,theme FROM $tab[user] WHERE id='$id';"));


    if($gametheme!=$user[3])
    {
    mysql_query("UPDATE $tab[user] SET theme='$gametheme' WHERE id='$id'");
    $user = mysql_fetch_array(mysql_query("SELECT online,status,username,theme FROM $tab[user] WHERE id='$id';"));
    }

    <form method="post" action="" name="usertheme">
    <select name="gametheme" onChange="document.usertheme.submit()">
    <option value="0" <? if($user[3]==0){echo "selected";} ?>>blue</option>
    <option value="1" <? if($user[3]==1){echo "selected";} ?>>purple</option>
    <option value="2" <? if($user[3]==2){echo "selected";} ?>>red</option>
    <option value="3" <? if($user[3]==3){echo "selected";} ?>>green</option>
    <option value="4" <? if($user[3]==4){echo "selected";} ?>>dark blue</option>
    <option value="5" <? if($user[3]==5){echo "selected";} ?>>orange</option>
    </select>
    </form>

    If its being submitted correctly back, the problem is with your globals, they are not registered. Don't register them though, its better that they are off:
    Anywhere you have $gametheme, change it to $_POST['gametheme'], with the exception of the query and form, use mysql_real_escape_string($_POST['gametheme']) instead for the query, and the form is just fine as is.
    Also, I suggest adding a submit button as well for users whom do not use javascript.
