Select Random Products From Category

[cm_a93]

Hi all,

 

I am using zero supermarket sidebar on my store.

I want the module to select random products to display. 
This is what I think should be modified

if ($zsidebarsuperblock['block_type'] == _SBTPRODUCT_)

{

$zsidebarsuperblock['product_options'] = ZSidebarSuperBlock::initProductOptions($zsidebarsuperblock['product_options']);

 

$products = false;

$limit = (int)$zsidebarsuperblock['product_options']['limit'];

$random = false;

$order_by = $zsidebarsuperblock['product_options']['order_by'];

if ($order_by == 'random')

{

$random = true;

$order_by = null;

}

 

if ($zsidebarsuperblock['product_filter'] == _SPTFEATURES_)

{

$category = new Category(Context::getContext()->shop->getCategory(), $id_lang);

$products = $category->getProducts($id_lang, 1, $limit, $order_by, 'ASC', false, $random, $limit);

 

}

elseif ($zsidebarsuperblock['product_filter'] == _SPTNEW_)

$products = Product::getNewProducts($id_lang, 0, $limit);

elseif ($zsidebarsuperblock['product_filter'] == _SPTSPECIAL_)

$products = Product::getPricesDrop($id_lang, 0, $limit);

elseif ($zsidebarsuperblock['product_filter'] == _SPTSELLER_)

$products = ProductSale::getBestSales($id_lang, 0, $limit, 'date_add');

elseif ($zsidebarsuperblock['product_filter'] == _SPTSELECTED_)

$products = $this->getProductByArrayId($id_lang, $zsidebarsuperblock['product_options']['selected_products']);

elseif ($zsidebarsuperblock['product_filter'] == _SPTCATEGORY_)

{

$category = new Category((int)$zsidebarsuperblock['product_options']['selected_category'], $id_lang);

$products = $category->getProducts($id_lang, 1, $limit, $order_by, 'ASC', false, $random, $limit);

if ($products) {

shuffle($products);

array_splice($products, ($nb ? $nb : 10));

}

}

 

$blocks[] = array(

'title' => $zsidebarsuperblock['title'],

'block_type' => $zsidebarsuperblock['block_type'],

'custom_class' => $zsidebarsuperblock['custom_class'],

'number_column' => $zsidebarsuperblock['product_options']['number_column'],

'products' => $products,

);

}

 

Can anyone tell me how to modify it to select random products
