This is my small script for changing a user's rank on admin page, I was wondering how you could make it automatically run PHP after you changed the option, so I want it to be able to run without you need to press a submit button.

onchange="javascript: {script to submit form}"

im not a java expert but i do know this should work, put it in the <select> tag. replace "{script to submit form}" with a script that will submit the form, and bingo you have it working. the only reason i did "{script to submit form}" was because i dont know that

PHP Code:

$rank = $profile[rank];
echo ("<br />Rank:<form method=\"post\">");
if ($rank == 1) {
    $rank = "Member";
    echo ("<select name=\"rank\">
    <option name=\"1\" selected=\"selected\" value=\"1\">$rank
    <option name=\"2\" value=\"2\">Moderator
    <option name=\"3\" value=\"3\">Administrator
    </select>");
    }
if ($rank == 2) {
    $rank = "Moderator";
    echo ("<select name=\"rank\">
    <option name=\"1\" value=\"1\">Member
    <option name=\"2\" selected=\"selected\" value=\"2\">$rank
    <option name=\"3\" value=\"3\">Administrator
    </select>");
    }
if ($rank == 3) {
    $rank = "Administrator";
    echo ("<select name=\"rank\">
    <option name=\"1\" value=\"1\">Member
    <option name=\"2\" value=\"2\">Moderator
    <option name=\"3\" selected=\"selected\" value=\"3\">$rank
    </select>");
    }
if ($_POST[update])
{ 
if ($_POST['1']) {
$rank = "1";
} 
if ($_POST['2']) {
$rank = "2";
}
if ($_POST['3']) {
$rank = "3";
}
mysql_query("UPDATE users SET rank = '$rank' WHERE username = '$profile[username]'") or die(mysql_error());
}
echo ("<br />Real Name: $profile[name]<br />
Location: $profile[location]<br />
Paypal: $profile[paypal]<br />
Email: $profile[email]<br /><br />
Registered on: $profile[date]<br /><br />
<input type=\"submit\" name=\"update\" value=\"Update\"> <input type=\"submit\" name=\"delete\" value=\"Delete\">
</form> 


I've decided just to make it a update button, this kind of works. It's weird, it will remove all other information in the database and will make the rank = 0... when the default is 1.
