WordPress delete checkout button from cart widget

Solution:1

You can do it by using the css or need to check your code to find and remove the button. If you are using the plugin then please check for the hook you are using and edit that one.

With the CSS, you can easily hide the checkout button.

Use it like

.widget_sidebar .checkout_button {
    display: none;
}

Solution:2

There are two ways you can achieve this.

The first method is to remove the button using the Woocommerce Hook. Add the below code in your functions.php file

  function my_woocommerce_widget_shopping_cart_proceed_to_checkout() 
    {
        return;
    }
    add_action( 'woocommerce_widget_shopping_cart_buttons', 

'my_woocommerce_widget_shopping_cart_proceed_to_checkout', 20 );

Another method is by using the CSS to hide that particular button.

Add display: none to that specific button by identifying its class.

.woocommerce-mini-cart__buttons .checkout.wc-forward {display: none !important;}
