If I turn on :

                    <?php $group_level = 'intermediate 1'; ?>

Then it does lock the $group_level to intermediate 1.

groupinfo_edit.php

<tr>
                    <td>Level</td>
                    <td>
                    <?php //$group_level = 'intermediate 1'; ?>
                    <?php
                    $row2 = mysql_query("SELECT * FROM `level`") or die(mysql_error());
                    echo '<select name="group_level">';
                    while($data2 = mysql_fetch_array($row2)){
                        echo '<option value="'.$data2['level
                        _name'].'"';
                        if($group_level == $data2['level_name']){
                        echo 'selected="selected"';}
                        echo '>'.$data2['level_name'].'</option>';
                        }                       
                    echo '</select>';    
                    ?>


                    </td>
                </tr>

My problem is why it does not want to record group_level:

groupinfo_edit.php

<?php

// Check if session is not registered, redirect back to main page.
// Put this code in first line of web page.


session_start();


if(!isset($_SESSION['username']))
    {
    header("location:index.php");
    exit;
    }

?>

<?php include('../adminfooter.php'); ?>
</body>
</html>

I wonder why echo $group_level; does not show anything -- (right below "Test") -- $group_package and $group_payment does show their value.

Please help.

Thanks before.

If you output print_r($_POST); does it show group_level ?

I already try:

line 95: echo $group_level;

It doesn't show anything. Line 96 - 97 shows somethings.

I already try:

That's not what I asked.

Array ( [group_name] => PT Indonusa [group_info] => Group Indonusa Information [group_package] => 16 lessons [group_level] => [group_teacher] => John Rayne [group_payment] => PAID [ok] => Save )

Group level is empty

Check the HTML, specifically for the generated select tag and paste that here.

I do not understand. I already paste the whole code (groupinfo_edit.php) above.

Do you mean HTML Generated - Source Code - IE:

Yes. That's what I meant. See this:
