How to access smarty functions in template using CodeIgniter? - El Forum - 11-07-2013

Hello guys just need a little help here.
I have a difficulty in accessing smarty function in my template. Here's my sample code.

Controller:

Code:
class Category_Controller extends CI_Controller{

      public function __construct(){

       parent::__Construct();

      }

      public function index(){

       $title = "Welcome to my page!";

       $category = $this->category_model->getAllCategory();

       $category_data = $category->result_array();

       $this->smartylib->assign('category',$category_data);

       $this->smartylib->assign('title',$title);

       $this->smartylib->display('index.tpl');

      }

     }

My Template

Code:
&lt;html&gt;

     &lt;head&gt;

      &lt;title&gt;{$title}&lt;/title&gt;

     &lt;/head&gt;

     &lt;body&gt;

      <table>

       <tr>

        <td>SALES CATEGORY ID</td>

        <td>SALES CATEGORY NAME</td>

        <td>SALES CATEGORY DESCRIPTION</td>

        <td>COUNT</td>

       </tr>

       <tr>

        {assign var = x value = ''}

        {assign var = y value = ''}

        {foreach $category as $x}

         <tr>

          <td>{$x['salescatid']}</td>

          <td>{$x['salescatname']}</td>

          <td>{$x['salescatdesc']}</td>

          <td>{$x['salescatname'] | count_characters}</td>

         </tr>

        {/foreach}

       </tr>

      </table>

      {$smarty.now |date_format:'%Y-%m-%d %H:%M:%S'}

     &lt;/body&gt;

    &lt;/html&gt;

I have a smarty error in the output. In my code I need to count the salescatname and display the output in the table also. And below. I need to post the date. But how can I access functions?
That's all thanks in advance.
