I am trying to get the original theme preview block to work, and I previously made a post in another topic about this but it deserves it's own.

I did some testing but I came up with a funky list that contains all of the themes on one line without the ability to change them, obviously. Here are my changes:

Code:


<?php

/************************************************************************/

if ( !defined('BLOCK_FILE') ) {
    Header('Location: ../index.php');
    die();
}

global $user, $userinfo, $Default_Theme, $cookie;

getusrinfo($user);
$content .= '<center>';
$content .= '<form action="modules.php?name=Your_Account" method="post">';
$content .= '<p></p>';
$content .= '<BR>';
$content .= '<select name="theme" onchange=submit();>';
$handle=opendir('themes');
while ($file = readdir($handle)) {
if ( (!ereg("[.]",$file)) ) {
$themelist .= '' . $file . '';
}
}
closedir($handle);
$themelist = explode(' ', $themelist);
sort($themelist);
for ($i=0; $i < sizeof($themelist); $i++) {
if($themelist[$i]!='') {
$content .= '<option value="' . $themelist[$i] . '"';
if((($userinfo[theme]=="") && ($themelist[$i]=="$Default_Theme")) || ($userinfo[theme]==$themelist[$i])) $content .= "selected";
$content .= '> ' . $themelist[$i] . 'n';
}
}
$content .= '</select>';

$content .= '<input type="hidden" name="storynum" value="$userinfo[storynum]">';
$content .= '<input type="hidden" name="ublockon" value="$userinfo[ublockon]">';
$content .= '<input type="hidden" name="ublock" value="$userinfo[ublock]">';
$content .= '<input type="hidden" name="uname" value="$userinfo[uname]">';
$content .= '<input type="hidden" name="user_id" value="$userinfo[user_id]">"';
$content .= '<input type="hidden" name="op" value="savetheme">';

$content .= '</form>';
$content .= '</center>';

?>


Cant even remember the original, but I'm betting I did something wrong...

Your block-file use some old code. With PHP5 we can do it easier.

1. we need every time in a block the varible $content = ''; before we extend it like this $content .= '';
2. to scan a dir we can use in PHP5 Only registered users can see links on this board! Get registered or login! without to start a handle with opendir
3. ereg is since PHP5x deprecated and scandir loads all for us in an array
4. to make sure to catch really a folder, we can use Only registered users can see links on this board! Get registered or login! for checking the directory
5. the field-names from the users-table are currently a little bit different but its only needed to catch the user_id
6. to catch the current theme we need the global $ThemeSel
7. at the end we spend a little bit much more love in the validation of the xHTML markup and we have a theme-switcher for users

Code:
<?php

if ( !defined('BLOCK_FILE') ) {Header('Location: ../index.php'); die();}
if (!defined('PHP_EOL')) define('PHP_EOL', strtoupper(substr(PHP_OS,0,3) == 'WIN') ? "\r\n" : "\n");
global $user, $ThemeSel;
$content = '';
if (is_user($user)) {
   $userinfo = getusrinfo($user);
   $folder = 'themes';
   if (is_dir($folder)) {
      $content .= '<form action="modules.php" method="post">' . PHP_EOL
              . '<div class="text-center">' . PHP_EOL
              . '<select name="theme" onchange="submit();">' . PHP_EOL;
      $themelist = scandir($folder);
      sort($themelist);
      $count_themelist = count($themelist);
      $exclude = array('.','..');
      for ($i=0; $i < $count_themelist; $i++) {
         if (is_dir($folder . '/' . $themelist[$i]) && !in_array($themelist[$i], $exclude)) {
            $content .= '   <option value="' . $themelist[$i] . '"' . ($themelist[$i] == $ThemeSel ? ' selected="selected"' : '') . '>' . $themelist[$i] . '</option>' . PHP_EOL;
         }
      }
      unset($themelist);
      $content .= '</select>' . PHP_EOL
              . '<input type="hidden" name="user_id" value="' . $userinfo['user_id'] . '" />' . PHP_EOL
              . '<input type="hidden" name="name" value="Your_Account" />' . PHP_EOL
              . '<input type="hidden" name="op" value="savetheme" />' . PHP_EOL
              . '</div>' . PHP_EOL
              . '</form>' . PHP_EOL;       
   }
} else {
   $userinfo = array();
   $content .= '<div class="text-center">Only for users!</div>' . PHP_EOL;
}
