How to display a listbox inside a directory

[KAILEY]

Here is my problem. I have a form of update, and would like to display the names of the images contained in a folder all in a listbox. That way I could select the image I want through the listbox and do a little update. But as my knowledge is concerned, php is quite limited (sql insert, update and delete). So how can I display a listbox inside a directory?

<select name="listDir">
<?php
$rep ='upload/';
if (!is_dir ($rep)) {
    echo 'Error, ', $dir,' is not a valid directory';
    exit;
}
$dir = opendir ($rep);
        while (false !== ($file = readdir ($dir))) {
            if ($file !== '..' && $file !== '.') {
                echo '<option value="',$file,'">',$file,'</option>';
            }
        }
?>
</select>

Tries more or less it, I do not know if it will work the first time, trying to understand/debug (no wizard in there) and if something is wrong does not hesitate to ask further questions:

<select name="image">
<?php
$d = dir("/myaccount/whichcontains/theimages" );
while (false !== ($entry = $d->read()))
{
   if ('.' !== $entry && '..' != $entry)
   {
   ?>
      <option value="<?php echo $entry; ?>"><?php echo $entry; ?></option>
   <?php
   }
}
$d->close();
?>
</select>

If so, its the penalty, beginning before the huge eternal great php, I look and try to understand, but it is not working or I think I missed something. I need little more explanation on this.

The method I gave you does the same thing that you have found, but object-oriented.

Instead of using opendir () which returns you $dir, use readdir() on it and end closedir(), you use the dir() which returns you an object of type Directory.

Then you use the object methods directly.

$dir = opendir($rep); 
$entry = readdir($rep); 
closedir($rep);

$d = dir($rep); 
$entry = $d->read();
$d->close();
