Use while and counter in smarty template ?

[prestashop_newuser]

Hi,

I have my code in php for some other project is like this

  

<div class="post-wrap">

  $i = 0;

  while ( have_posts() )

  $i++;

  if($i==1) {

    $class= 'active';

  }

  else {

    $class= '';

  }

  

 <div class="box '.$class.'"></div>

 endwhile;

 </div>

 

 Now this gives the output like 

 

<div class="box active"></div>

 <div class="box"></div>

 <div class="box"></div>

 

 In this way I have made all the posts fadein and fadeout by jQuery.

 

 with the same reference I want to make fadein and fadeout some texts. For that I have developed module. In that I am getting all the values from database. So my code for module like this

 

 public function hookfooter($params) {

  $popup_styles = "SELECT * FROM "._DB_PREFIX_."database ORDER BY `id` DESC LIMIT 1";

  $popup_styles_settings = Db::getInstance()->ExecuteS($popup_styles);

  $this->context->smarty->assign('PopupStyles',$popup_styles_settings);

  return $this->display(__FILE__, 'views/templates/front/footer-display.tpl');

 }

 Here I have fetched the data and I have assigned the values to smarty.

 Inside smarty my code is like this

 

{foreach from=$sliderValues item=row}

  <div class="box">name</div>

  <div class="box">name2</div>

  <div class="box">name3</div>

 {/foreach}

 

but here I don't know how to use while and make loop counter so that I can add class active for jquery.

So can somone kindly tell me how to make this work? Any help and suggestions will be really appreciable. Thanks

when I used {while} loop the site showed totally blank page. Can you tell me how to solve this issue?
