Опции в категории Opencart 2

[voron121]

Доброго времени суток. Решил реализовать опции в категории opencart 2,0,3,1. Пробовал готовый модуль - но с ним есть не большие траблы. Собственно что я предпринял:

В контроллере category.php добавил сл строки :
перед $data['products'][] = array(

 

$var_currency = array();
    $var_currency['value'] = $this->currency->getValue();
    $var_currency['symbol_left'] = $this->currency->getSymbolLeft();
    $var_currency['symbol_right'] = $this->currency->getSymbolRight();
    $var_currency['decimals'] = $this->currency->getDecimalPlace();
    $var_currency['decimal_point'] = $this->language->get('decimal_point');
    $var_currency['thousand_point'] = $this->language->get('thousand_point');
    $data['currency'] = $var_currency;
	$options = $this->model_catalog_product->getProductOptions($result['product_id']);

в самом массиве добавил сл:

	'options' => $options,
	'price_no_format' => $result['price'],
    'special_no_format' => $result['special'],

Далее во вьюхе вывел сами опции 

<div class="options">
    <?php if ($product['options']) { ?>
    <div id="option_<?php echo $product['product_id']; ?>">
    <?php foreach ($product['options'] as $option) { ?>
    <?php if ($option['type'] == 'select') { ?>
    <div id="option-<?php echo $option['product_option_id']; ?>" class="option">
    <?php if ($option['required']) { ?>*<?php } ?> <label><?php echo $option['name']; ?>:</label><br />
    <select name="option[<?php echo $option['product_option_id']; ?>]" onchange="recalc(<?php echo $product['product_id']; ?>);"  id="<?php echo $product['product_id']; ?>">
	<option value="" price_prefix="" price=""><?php echo $text_select; ?></option>
    <?php foreach ($option['product_option_value'] as $option_value) { ?>
    <option value="<?php echo $option_value['product_option_value_id']; ?>" price_prefix="<?php echo $option_value['price_prefix']; ?>" price="<?php echo $option_value['price']; ?>"><?php echo $option_value['name']; ?> <?php if ($option_value['price']) { ?>(<?php echo $option_value['price_prefix']; ?><?php echo $option_value['price']; ?>)<?php } ?></option>
    <?php } ?>
    </select>
    </div>
    <?php } ?>
    <?php if ($option['type'] == 'radio') { ?>
    <div id="option-<?php echo $option['product_option_id']; ?>" class="option">
	<?php if ($option['required']) { ?>*<?php } ?> <label><?php echo $option['name']; ?>:</label><br />
    <?php foreach ($option['product_option_value'] as $option_value) { ?>
    <input type="radio" price_prefix="<?php echo $option_value['price_prefix']; ?>" price="<?php echo $option_value['price']; ?>" onchange="recalc(<?php echo $product['product_id']; ?>);" name="option[<?php echo $option['product_option_id']; ?>]" value="<?php echo $option_value['product_option_value_id']; ?>" id="option-value-<?php echo $option_value['product_option_value_id']; ?>" />
    <label for="option-value-<?php echo $option_value['product_option_value_id']; ?>"><?php echo $option_value['name']; ?> <?php if ($option_value['price']) { ?>(<?php echo $option_value['price_prefix']; ?><?php echo $option_value['price']; ?>)<?php } ?></label><br />
    <?php } ?>
    </div>
    <?php } ?>
	<?php if ($option['type'] == 'checkbox') { ?>
    <div id="option-<?php echo $option['product_option_id']; ?>" class="option">
	<?php if ($option['required']) { ?>*<?php } ?> <label><?php echo $option['name']; ?>:</label><br />
    <?php foreach ($option['product_option_value'] as $option_value) { ?>
    <input type="checkbox" price_prefix="<?php echo $option_value['price_prefix']; ?>" price="<?php echo $option_value['price']; ?>" onchange="recalc(<?php echo $product['product_id']; ?>);" name="option[<?php echo $option['product_option_id']; ?>][]" value="<?php echo $option_value['product_option_value_id']; ?>" id="option-value-<?php echo $option_value['product_option_value_id']; ?>" />
    <label for="option-value-<?php echo $option_value['product_option_value_id']; ?>"><?php echo $option_value['name']; ?> <?php if ($option_value['price']) { ?>(<?php echo $option_value['price_prefix']; ?><?php echo $option_value['price']; ?>)<?php } ?></label><br />
    <?php } ?>
    </div>
    <?php } ?>
	<?php } ?>
    </div>
    <?php } ?>
    </div>

Для того, что бы менялось значении цены взял код с модуля обновления цены для карточки товара 

<script type="text/javascript"><!--

function price_format(n)
{ 
    c = 2;
    d = '.'; // decimal separator
    t = ','; // thousands separator
    s_left = '';
    s_right = ' грн.';
      
    n = n * 1.00000000;

    //sign = (n < 0) ? '-' : '';

    //extracting the absolute value of the integer part of the number and converting to string
    i = parseInt(n = Math.abs(n).toFixed(c)) + ''; 

    j = ((j = i.length) > 3) ? j % 3 : 0; 
    return s_left + (j ? i.substr(0, j) + t : '') + i.substr(j).replace(/(\d{3})(?=\d)/g, "$1" + t) + (c ? d + Math.abs(n - i).toFixed(c).slice(2) : '') + s_right; 
}

function calculate_tax(price)
{
        return price;
}

function process_discounts(price, quantity)
{
        return price;

Цена обновляется при выборе  опции. Но вот в чем трабла - какую бы опцию не выбрали товар в корзину уходит со старой ценой (та цена, которую опенкарт выводит по умолчанию). 

Прошу помощи - сломал голову что исправить что бы в корзину товар уходил с адекватной ценой
