【问题标题】:How to only change the value from 'apply_filters' via child theme functions?如何仅通过子主题功能更改“apply_filters”的值?
【发布时间】:2021-01-07 21:00:06
【问题描述】:

我有以下代码在我想删除的电子邮件的订单摘要中输出文本“通过 nameOfshippingMethod”:

$shipping .= apply_filters( 'woocommerce_order_shipping_to_display_shipped_via', '&nbsp;<small class="shipped_via">' . sprintf( __( 'via %s', 'woocommerce' ), $this->get_shipping_method() ) . '</small>', $this );

从采取侵入性最小的方法来看,是否可以以某种方式更改此apply_filters 的值,或者我是否必须替换我的子functions.php 中的整个函数?

如果有人能帮助我,我将不胜感激!

为了完整起见,整个函数是(位于“abstract-wc-order.php”中):

public function get_shipping_to_display( $tax_display = '' ) {
    $tax_display = $tax_display ? $tax_display : get_option( 'woocommerce_tax_display_cart' );

    if ( 0 < abs( (float) $this->get_shipping_total() ) ) {

        if ( 'excl' === $tax_display ) {

            // Show shipping excluding tax.
            $shipping = wc_price( $this->get_shipping_total(), array( 'currency' => $this->get_currency() ) );

            if ( (float) $this->get_shipping_tax() > 0 && $this->get_prices_include_tax() ) {
                $shipping .= apply_filters( 'woocommerce_order_shipping_to_display_tax_label', '&nbsp;<small class="tax_label">' . WC()->countries->ex_tax_or_vat() . '</small>', $this, $tax_display );
            }
        } else {

            // Show shipping including tax.
            $shipping = wc_price( $this->get_shipping_total() + $this->get_shipping_tax(), array( 'currency' => $this->get_currency() ) );

            if ( (float) $this->get_shipping_tax() > 0 && ! $this->get_prices_include_tax() ) {
                $shipping .= apply_filters( 'woocommerce_order_shipping_to_display_tax_label', '&nbsp;<small class="tax_label">' . WC()->countries->inc_tax_or_vat() . '</small>', $this, $tax_display );
            }
        }

        /* translators: %s: method */
        $shipping .= apply_filters( 'woocommerce_order_shipping_to_display_shipped_via', '&nbsp;<small class="shipped_via">' . sprintf( __( 'via %s', 'woocommerce' ), $this->get_shipping_method() ) . '</small>', $this );

    } elseif ( $this->get_shipping_method() ) {
        $shipping = $this->get_shipping_method();
    } else {
        $shipping = __( 'Free!', 'woocommerce' );
    }

    return apply_filters( 'woocommerce_order_shipping_to_display', $shipping, $this, $tax_display );
}

【解决方案1】:

借助 Howard E 的有用提示,我能够生成以下有效的 WooCommerce 过滤器:

add_filter( 'woocommerce_order_shipping_to_display_shipped_via', 'woocommerce_order_shipping_to_display_shipped_via_remove', 10);
   
function woocommerce_order_shipping_to_display_shipped_via_remove( $no_via ) {
    $no_via = '&nbsp;<small class="shipped_via"></small>' ;
    return $no_via;
}
