Simple, Variable, Group and Virtual. * Now if you have simple product and want to add through ajax, that is already in woo-commerce setting. * This plugin is adding Ajax functionality for Variable products only as that is not inside woo-commerce. To get that functionality working, you only need to activate plugin. * If its not working, it means your template have missing woo-commerce default classes in html. * It will be good if you can provide testing url, so i can look into it and give you exact solution. * Thread Starter [M.Danz](https://wordpress.org/support/users/mdanz-1/) * (@mdanz-1) * [11 years, 2 months ago](https://wordpress.org/support/topic/how-does-this-work-23/#post-5836230) * I’m not following. For example, if i’m on a single product page with variations and i click the add to cart button.. what is the plugin intended to do? I thought that if i press add to cart the page won’t refresh & the cart will be updated via ajax? * Here is a link with variations.. * [https://www.plantsandtreesonline.co.uk/product/shiplap/shiplap-timber/](https://www.plantsandtreesonline.co.uk/product/shiplap/shiplap-timber/) * Plugin Author [Rishi Mehta](https://wordpress.org/support/users/rcreators/) * (@rcreators) * [11 years, 2 months ago](https://wordpress.org/support/topic/how-does-this-work-23/#post-5836231) * Hi Danz, * Thanks for the quick Response. I checked your link. Things which are come to my mind first. * 1) you need to install and activate plugin on site, so i can test it from here and give you respond based on that. * 2) You are missing one product type variable class in your template. I have attached Screen shot where you need to put this class “product-type-variable” – Without this class, js will not work. * > [View post on imgur.com](https://imgur.com/vWMEn2H) * Thread Starter [M.Danz](https://wordpress.org/support/users/mdanz-1/) * (@mdanz-1) * [11 years, 2 months ago](https://wordpress.org/support/topic/how-does-this-work-23/#post-5836256) * I’ve activated the plugin and added the product-type-variable and when pressing add to cart the page still refreshes?

It remains same all the time while it actually different. * Let me know after you disable that plugin, so i can cross check, whether it solved the issue or anything more i need to look into. * Thread Starter [M.Danz](https://wordpress.org/support/users/mdanz-1/) * (@mdanz-1) * [11 years, 2 months ago](https://wordpress.org/support/topic/how-does-this-work-23/#post-5836258) * I disabled the plugin and still the page refreshes when pressing add to cart. The variable not changing is due to price rounding up function in functions.php * ``` add_filter( 'woocommerce_get_price_excluding_tax', 'round_price_product', 10, 1 ); add_filter( 'woocommerce_get_price_including_tax', 'round_price_product', 10, 1 ); add_filter( 'woocommerce_tax_round', 'round_price_product', 10, 1); add_filter( 'woocommerce_get_price', 'round_price_product', 10, 1); function round_price_product( $price ){ // Return rounded price if ($price % 10 > 5) { $newPrice = floor($price / 10) * 10 + 9.95; } elseif ($price % 10 <= 5) { $newPrice = floor($price / 10) * 10 + 5.95; } return $newPrice; } ``` * I need this function for website.
