I have seen several posts regarding hiding unwanted fields in the frontend editor and several posts asking about getting the user's group, and I needed to do both, so here's my solution.

Put the following code near the top of form.php

<?php// get user ID$user = &JFactory::getUser();$userId = $user->get('id');// get user Group$db =& JFactory::getDBO();$query = "  SELECT ".$db->nameQuote('group')."    FROM ".$db->nameQuote('jos_k2_users')."    WHERE ".$db->nameQuote('userID')." = ".$db->quote($userId).";  ";$db->setQuery($query);$userGroup = $db->loadResult();?>

 

You can then surround whatever element you want to hide as in the following example where I hide the toggle sidebar unless user is editor or site owner.

 

<?php if($userGroup == 2 OR $userGroup == 4) : ?>    <div id="k2ToggleSidebarContainer">     <a href="#" id="k2ToggleSidebar"><?php echo JText::_('Toggle sidebar'); ?></a>    </div>   <?php endif; ?>

 

These are my user group numbers and will be different on your site. Just check your database (jos_k2_user_groups) to get the numbers that correspond to each of your groups. 

No rating system here so i will make one *****

This can be used in many instances, especially the query of the database to get info

William,

Here's a great resource for writing db queries in Joomla: docs.joomla.org/How_to_use_the_database_classes_in_your_script.William White said:

Where is file form.php? I can;t find it. Please help me!

/components/com_k2/views/item/tmpl/form.php

I have extra fields, Can i hide this fileds?

In the input form or in the item view?

I need to hide Extra fields from non-registered users. If a user is logged in Extra Fields need to show.

Can You help me?

In item.php add the following near the top of the page.

<?php$user = &JFactory::getUser();$userId = $user->get('id');?>

Then surround the extra fields (lines 254-268) with the following.

<?php if($userId != 0) : ?>

    extra fields stuff

<?php endif; ?>
