How toshow icon or button when a user is not logged

[pippo67]

Hello,

I created a custom comments module. I would like to display the trash icon in the comment only for the user is logged in. I created this code in the tpl file that deals with viewing the comments. According to your experience is correct?

<table>

  {foreach from=$comments item=$row}

   <tr> 

     <td>

       {if $logged}

            {$row[‘firstname’]} {$row[‘lastname’]}

             <i  class='fa fa-trash-0'></i>

       {else}

            {$row[‘firstname’]} {$row[‘lastname’]}   

       {/if}

     </td>

  </tr>

</table>

Thanks in advance and sorry for the english.
