<p>This plugin will hide the WooCommerce “Update Cart” button and reload the quantity changes dynamic over jQuery. You don’t need this extra click anymore!</p>
<p>This Plugin is based on a posting on StackExchange related to WordPress developers. I modified the basic concept and created a plugin out of it that WordPress users with less experience in PHP can integrate this function easily without destroying their functions.php file.</p>
<p><strong>There are no options</strong>. Just activate the plugin and it will work.</p>
<p><strong>Please note:</strong> Since WooCommerce introduced block-based templates, this plugin only works when you are using the classic WooCommerce cart shortcode <code>[woocommerce_cart]</code> added to a page. It is not needed when using the WooCommerce Cart Block.</p>
<h3>Plugin Requirements</h3>
<ul>
<li>This plugin requires WordPress 4.9 or greater</li>
<li>This plugin requires WooCommerce 3.0.0</li>
<li>This plugin requires PHP 5.6 or greater</li>
</ul>
