You can do this by adding a filter. The plugin uses the current product price so you have to hook into that. Following the values on the tutorial link you can do something like:

add_filter('woocommerce_get_price', 'add_fee_to_price' , 10, 2);

function add_fee_to_price( $price, $product ) {
        $category_ID = '23';
        $excost = 0;
        $product_id=$product->id;
        $terms = get_the_terms( $product_id, 'product_cat' );
        foreach ($terms as $term){
                if($term->term_id == $category_ID){
                        $excost = 6;
                }
        }
    return ($price+$excost);
}

You can put this code somewhere like your functions.php file.

Please note that this may change the displayed priced on the product page as well. If you find something is not displaying as it should after that code just remove it.

You are avesome but it add fee for every product not for all price 1 fee. example. now is: price + fee x qty ,is it posible price x qty + fee ?

I see what you wanted now. This approach requires a some changes on the plugin. I added 2 filters to the plugin to make that possible. When get the notification that the plugin has been updated replace yours with the new version and then on the above code change:

add_filter('woocommerce_get_price', 'add_fee_to_price' , 10, 2);

to

add_filter('woocommerce_tm_final_price_extra_fee', 'add_fee_to_price' , 10, 2);

Can you tell the url for that page?

Make sure that you set the Number of Decimals in WooCommerce Currency Options under WooCommerce Settings to the number of decimcals you want. The plugin uses this setting to conform with store options.

See this page in the demo : http://finalprice.themecomplete.com/product/flying-ninja/ and you will see that it does calculate the price correctly. The setting in the demo is 6 Number of Decimals.

Sorry for no reply. The problem in this plugin is not for showing decimals its problem in calculating. Then product price is 0.0728856 and i buy 1000pcs. your final price plugin show 70.00 its not corect and then i add to cart woocomerce cart calculate it 72.89 and its corect. I think in future i will be not onely one who see it so i think it would be nice to fix it.

I really don’t know what is causing this on your site. I refer you again to the above link I posted http://finalprice.themecomplete.com/product/flying-ninja/

I changed the product price to 0.0728856 for your example and it is working as intended. Set the quantity to 1000 and the final price box displays 72.8856000. I set the decimals back to default 2 and the final total box displays 72.89. The current setting on the site is 2.

Again, please check your woocommerce setting “Number of Decimals”. The plugin uses that number to display decimals. There is nothing wrong with how the price is calculated.

The only thing I can is that you are using variations and somehow that is miscalculated.

If you can refer me to a url that is not showing the price correctly I could identify that issue for you. Actually, I think that is the case. I’ll see if I can find any work around for that.

I find out. the price is calculating bad then the price is diferent in variations, but its not logical. Then i make all variations diferent price its calculating bad. But i dont now is it yours plugin or woocommerce bug. http://b2bprint.dk/product/test/ this is product with diferent variation price. http://b2bprint.dk/product/test2/ this is product with same variation price and its calculate corect.

I found what the issue is. It is indeed on variations only. As the calculation is JavaScript based it takes into account only what is displayed on the js data provided by woocommerce. I found a workaround for that though and I already issued an update to fix that. If you cannot wait for the update queue please send me an email through my profile page and I will send you the update.
