php - Joomla, how to display category name in module latest -

i've been trying display category name after contents of 'latest' module in joomla.

i've made query in phpmyadmin , works. when try use in php module template page page stops @ point php should start.

$db = &jfactory::getdbo();  $id = jrequest::getstring('id');  $db->setquery("select `title` `#__categories` `id` = " .$item->catid);  $category = $db->loadresult(); echo $category; 

when replace $item->catid fixed number, works in phpmyadmin. can tell me go wrong?

thanks

$item having category title no need through db query. can in tmpl file. can category using $item->category_title

<ul class="latestnews<?php echo $moduleclass_sfx; ?>"> <?php foreach ($list $item) :  ?>     <li itemscope itemtype="http://schema.org/article">         <a href="<?php echo $item->link; ?>" itemprop="url">             <span itemprop="name">                 <?php echo $item->title; ?>-                 <b><?php echo $item->category_title; ?></b>             </span>         </a>     </li> <?php endforeach; ?> </ul>
