    $data['heading_title'] = $this->language->get('heading_title');      $data['text_tax'] = $this->language->get('text_tax');      $data['button_cart'] = $this->language->get('button_cart');     $data['button_wishlist'] = $this->language->get('button_wishlist');     $data['button_compare'] = $this->language->get('button_compare');      $this->load->model('catalog/product');      $this->load->model('tool/image');      $data['products'] = array();      if (!$setting['limit']) {         $setting['limit'] = 4;     }      if (!empty($setting['product'])) {         $products = array_slice($setting['product'], 0, (int)$setting['limit']);          foreach ($products $product_id) {             $product_info = $this->model_catalog_product->getproduct($product_id);              if ($product_info) {                 if ($product_info['image']) {                     $image = $this->model_tool_image->resize($product_info['image'], $setting['width'], $setting['height']);                 } else {                     $image = $this->model_tool_image->resize('placeholder.png', $setting['width'], $setting['height']);                 }                  if (($this->config->get('config_customer_price') && $this->customer->islogged()) || !$this->config->get('config_customer_price')) {                     $price = $this->currency->format($this->tax->calculate($product_info['price'], $product_info['tax_class_id'], $this->config->get('config_tax')));                 } else {                     $price = false;                 }                  if ((float)$product_info['special']) {                     $special = $this->currency->format($this->tax->calculate($product_info['special'], $product_info['tax_class_id'], $this->config->get('config_tax')));                 } else {                     $special = false;                 }                  if ($this->config->get('config_tax')) {                     $tax = $this->currency->format((float)$product_info['special'] ? $product_info['special'] : $product_info['price']);                 } else {                     $tax = false;                 }                  if ($this->config->get('config_review_status')) {                     $rating = $product_info['rating'];                 } else {                     $rating = false;                 }                  $data['products'][] = array(                     'product_id'  => $product_info['product_id'],                     'thumb'       => $image,                     'name'        => $product_info['name'],                     'description' => utf8_substr(strip_tags(html_entity_decode($product_info['description'], ent_quotes, 'utf-8')), 0, $this->config->get('config_product_description_length')) . '..',                     'price'       => $price,                     'special'     => $special,                     'tax'         => $tax,                     'rating'      => $rating,                     'href'        => $this->url->link('product/product', 'product_id=' . $product_info['product_id'])                 );             }         }     }      if ($data['products']) {         if (file_exists(dir_template . $this->config->get('config_template') . '/template/module/featured.tpl')) {             return $this->load->view($this->config->get('config_template') . '/template/module/featured.tpl', $data);         } else {             return $this->load->view('default/template/module/featured.tpl', $data);         }     } } 

}

every product in opencart has "sort order" field on "data" tab, can fill when add or edit product:

go file:

catalog/controller/module/featured.php 

add these line products array

'sort_order' => $product_info['sort_order'], 'date_added' => $product_info['date_added'] 

and use array_multisort bellow:

$temp_array = array(); foreach ($data['products'] $key => $row){     $temp_array[$key] = $row['sort_order']; } array_multisort($temp_array, sort_asc, $data['products']); 

insert above code before if ($data['products']) {

i've tested on opencart 2.1.0.1, hope you.
