Woocommerce adds 1 extra item to cart

Hey angryjedi

What version are you using? I had the problem with version 1.6.5.2 but I think it’s been fixed in version 1.6.6, try updating woocommerce, see if that works.

I was using version 1.6.5.2 when I had the problem and to fix it I added this code to the woocommerce-functions.php file around line 361. But this has changed alot since then.

// If we added the product to the cart we can now do a redirect, otherwise just continue loading the page to show errors
    if ($added_to_cart) {

		$url = apply_filters( 'add_to_cart_redirect', $url );

		// If has custom URL redirect there
		if ( $url ) {
			wp_safe_redirect( $url );
			exit;
		}
		Add this code to fix the problem
		// Redirect to cart option
		elseif (get_option('woocommerce_cart_redirect_after_add')=='yes' && $woocommerce->error_count() == 0) {
			wp_safe_redirect( $woocommerce->cart->get_cart_url() );
			exit;
		}

    }

I think the best thing to do is to submit a bug through Github and see if Mike can help.
