您将要筛选文本。下面是core WC中构建该文本的函数。在这两种情况下$this 将是产品。

/**
 * Get the add to cart button text for the single page.
 *
 * @access public
 * @return string
 */
public function single_add_to_cart_text() {
    return apply_filters( \'woocommerce_product_single_add_to_cart_text\', $this->get_button_text() ? $this->get_button_text() : _x( \'Buy product\', \'placeholder\', \'woocommerce\' ), $this );
}

/**
 * Get the add to cart button text.
 *
 * @access public
 * @return string
 */
public function add_to_cart_text() {
    return apply_filters( \'woocommerce_product_add_to_cart_text\', $this->get_button_text() ? $this->get_button_text() : _x( \'Buy product\', \'placeholder\', \'woocommerce\' ), $this );
}
