在woocommerce产品页面中添加价格后的自定义文字

I am working on salient theme for my E-commerce website. I want to show "B" after price in woocommerce product page. The page displays like "$99,99"
I want to make it displays like this: "$99,99 TEXT"

I have the code for it :

function change_product_price( $price ) {
    $price .= ' TEXT';
    return $price;
}
add_filter( 'woocommerce_get_price_html', 'cw_change_product_price_display' );
add_filter( 'woocommerce_cart_item_price', 'cw_change_product_price_display' );

Now I want to know where to add the code in woo-commerce directory. Any help would be appreciated.

thanks

add this code to the functions.php of your theme, in the end

function change_product_price( $price ) {
    $price .= ' TEXT';
    return $price;
}
add_filter( 'woocommerce_get_price_html', 'cw_change_product_price_display' );
add_filter( 'woocommerce_cart_item_price', 'cw_change_product_price_display' );

The name of the function you're calling in add_filter isn't the same as the name of your actual function. It seems you've forgotten the _display in the function name.

In the following code, the function is name cw_change_product_price_display and cw_change_product_price_display is called in add_filter

function cw_change_product_price_display( $price ) {
    $price .= ' TEXT';
    return $price;
}
add_filter( 'woocommerce_get_price_html', 'cw_change_product_price_display' );
add_filter( 'woocommerce_cart_item_price', 'cw_change_product_price_display' );
