OK thanks to all!!
Its work for me the following:
( paste in the function.php )
add_filter('woocommerce_get_price_html','members_only_price');
function members_only_price($price){
if(is_user_logged_in() ){
return $price;
}
else return '<a href="' .get_permalink(woocommerce_get_page_id('myaccount')). '">Accede</a> o <a href="'.site_url('/wp-login.php?action=register&redirect_to=' . get_permalink()).'">Regístrate</a> para ver precios!'.remove_action( 'woocommerce_after_shop_loop_item', 'woocommerce_template_loop_add_to_cart' ).remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_price', 10 ).remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_add_to_cart', 30 ).remove_action( 'woocommerce_after_shop_loop_item_title', 'woocommerce_template_loop_price', 10 );
}
this hide price and add to cart button and all prices in site.. if I dont login of course..
