   Hi, I got a little snippet of a theme options page. It displays a select multiple list of all categories you got.
   

   <?php
   	$news_categories = get_categories();
   	$news_categories[] = false;
   ?>
   
   <select id="<?php echo $data['category']; ?>" name="<?php echo $data['category']; ?>[]" multiple="multiple" style="height:150px;">
   <?php foreach($news_categories as $cat) : ?>
   <option value="<?php echo $cat->term_id; ?>" <?php if(is_array($val['category']) && in_array($cat->term_id, $val['category'])) echo ' selected="selected"'; ?>>
   <?php echo $cat->name; ?>
   </option>
   <?php endforeach; ?>
   </select>

   So I want to display instead of categories, pages. I changed somethings and now it looks like

   <?php
   	$news_categories = get_pages();
   	$news_categories[] = false;
   ?>
   
   <select id="<?php echo $data['category']; ?>" name="<?php echo $data['category']; ?>[]" multiple="multiple" style="height:150px;">
   <?php foreach($news_categories as $page) : ?>
   <option value="<?php echo $page->term_id; ?>" <?php if(is_array($val['category']) && in_array($page->term_id, $val['category'])) echo ' selected="selected"'; ?>>
   <?php echo $page->name; ?>
   </option>
   <?php endforeach; ?>
   </select>

   What is wrong in this code?

   - Steven.

   For one, pages don't have term_ids or names, so $page->term_id and $page->name would be wrong.
   After this line:
   

   <?php foreach($news_categories as $page) : ?>

   put this
   

   echo "<pre>"; print_r($page); echo "</pre>";

   That will show you all the values in $page...you should see the $page->ID and $page->post_title among others.

   One more question, when I want to get this option ( <?php echo get_option('catexclude');?> ) I need to place a "," after each page name, so I can put them under exclude=. How can I do this?

   That's worthy of a new topic.
