For Statement Question

[Titan85]

Well, I am running a for statement that show numbers up to the rank of the user viewing it. Here is the code:

<?php

$id = $_GET['id'];
$level = $_SESSION['level'];

// Get User Data
$get = mysql_query("SELECT * FROM `members` WHERE id = '$id' LIMIT 1") or die ("Error Getting User Data! \n<br />\n" .mysql_error());
$u = mysql_fetch_array($get);
$chk = mysql_num_rows($get);
//

// Check Levels
if ($level <= $u['level']) { echo('<meta http-equiv="refresh" content="2;URL=index.php" /> <div class="error">You do not have permission to edit this user</div>'); }
else {
//

    ########## If Form Sent ##########
    if ($_POST['edit']) {
        $username = mysql_real_escape_string($_POST['username']);
        $map = mysql_real_escape_string($_POST['map']);
        $level = mysql_real_escape_string($_POST['level']);
        
        // Format Username
        if ( !eregi('[IG]', $username) ) { $username = $username.'[IG]'; }
        if ( ereg('[ig]', $username) ) { $username = str_replace('[ig]', '[IG]', $username); }
        //
        
        // Insert Data
        $insert = mysql_query("UPDATE `members` SET username = '$username', map = '$map', level = '$level' WHERE id = '$id'") or die ("Error Updating User Data! \n<br />\n" .mysql_error());
            echo('<meta http-equiv="refresh" content="2;URL=index.php" /> <div class="message">The user '.$username.' has been edited.</div>');
        //
    }

    ########## If Form Not Sent ##########
    if (!$_POST['edit']) {
    
        // Check Results
        if ($chk < 1) { echo('<meta http-equiv="refresh" content="2;URL=index.php" /> <div class="error">Invalid User ID!</div>'); } else { ?>
    
            <form method="post" action="">
                <table width="400" align="center">
                    <tr>
                        <td>Username:</td>
                        <td><input type="text" name="username" value="<?php echo $u['username'] ?>" /></td>
                    </tr>
                    <tr>
                        <td>Test Map:</td>
                        <td><input type="text" name="map" value="<?php echo $u['map'] ?>" /></td>
                    </tr>
<?php if ($level >= 8) { ?>
                    <tr>
                        <td>Rank Level:</td>
                        <td>
                            <select name="rank">
<?php for ($r=1; $r < $level; $r++) { while ($r == $u['level']) { $s = 'selected="selected"'; } ?>
                                <option <?php echo $s ?>><?php echo $r ?></option>
<? } ?>
                            </select>
                        </td>
                    </tr>
<? } ?>
                    <tr>
                        <td></td>
                        <td><input type="submit" name="edit" value="Edit" /></td>
                    </tr>
                </table>
            </form>
    
    <? } 
    }
}

?>

The numbers are the ranks that the viewing user is allowed to promote another member to. The problem is that I need the member's (the one getting promoted/demoted) rank to be initially selected. Instead of just adding the 'selected="selected"' to the members rank, it adds it to every number after it finds the members rank because $s is now set. How can I make this work? Thanks in advance.

I'm not 100% on this without testing, but I think you may want to do an if statement instead of while on this line:

<?php for ($r=1; $r < $level; $r++) { while ($r == $u['level']) { $s = 'selected="selected"'; } ?>

so it would look something like this:

<?php for ($r=1; $r < $level; $r++) { if ($r == $u['level']) { $s = 'selected="selected"'; } ?>

Hope this helps.

I originally tried the if instead of the while, but it didn't work. I think the reason for this is that once the script finds the point where $r == $u['level'] is true, it will read it as true for every following run through. Any ideas on what to do? Thanks

<?php for ($r=1; $r < $level; $r++) { ?> 
  <option <?php echo $r === u['level'] ? 'selected="selected"' : '' ?>><?php echo $r ?></option> 
<? } ?>
