JReviews - HikaShop Compatible?

There is no integration with HikaShop. Looking at the documentation, it doesn't seem difficult to add to your views:
docs.reviewsforjoomla.com/downloads/ever...ywhere_2.0_Guide.pdf

You need to have the everywhere addon installed. Then, in the file show of the view product that you can edit via the menu Display->Views, you can add the code below at the end of the file in order to display the jreviews stuff:

require_once( 'components' . DS . 'com_jreviews' . DS . 'jreviews' . DS . 'framework.php' );
$JreParams = 'com_hikashop';
$JreParams = '';
$JreParams = 'everywhere';
$JreParams = 'index';
$JreParams = $this->element->product_id; //if you have variants, it's $this->element->main->product_id
$Dispatcher = new S2Dispatcher(’jreviews’,true);
$jreDetail = $Dispatcher->dispatch($JreParams);
echo $jreDetail[‘output’];


For the listing of products, it's the code below that you would have to add in one of the file listing_* of the view product (the name of the layout file depends on your settings):
require_once( 'components' . DS . 'com_jreviews' . DS . 'jreviews' . DS . 'framework.php' );
$JreParams = 'com_hikashop';
$JreParams = '';
$JreParams = 'everywhere';
$JreParams = 'category';
$JreParams = $row->product_id;
$Dispatcher = new S2Dispatcher(’jreviews’);
$jreDetail = $Dispatcher->dispatch($JreParams);
echo $jreDetail[‘output’];

You should ask JReviews support about the problem then. Note that it won't work without everywhere addon of JReviews installed.
