Woocommerce删除插件过滤器并替换为我自己的

filter woocommerce

JapeNZ · 技术社区 · 1 年前

我正试图根据自己的需要定制一个插件功能,并设法使我修改后的版本按需显示。不幸的是,我不知道如何删除原来的函数,所以现在出现了两个实例。

以下是插件的原始功能:

function aspwc_split_package_total_rows( $total_rows, $order, $tax_display ) {
    if ( get_option( 'advanced_shipping_packages_display_separately', 'no' ) != 'yes' ) {
        return $total_rows;
    }

    /** @var WC_Order $order */
    $shipping_items    = $order->get_items( 'shipping' );
    $key_position      = array_search( 'shipping', array_keys( $total_rows ) );
    $new_shipping_rows = array();

    foreach ( $shipping_items as $item ) {
        $package_name = $item->get_meta( 'package_name' ) ?: str_replace( ':', '', __( 'Shipping:', 'woocommerce' ) );

        $new_shipping_rows[ 'shipping_' . $item->get_id() ] = array(
            'label' => $package_name . ':', // Package name
            'value' => '<strong>' . $item->get_name() . ':</strong> ' . aspwc_get_shipping_to_display( $item, $order, $tax_display ) . '<br/><small>' . $item->get_meta( 'Items' ) . '</small>',
        );
    }

    // Remove original shipping line - Only when new rows are set (which should only happen when package names are stored)
    if ( ! empty( $new_shipping_rows ) ) {
        unset( $total_rows['shipping'] );
    }

    // Add package line(s)
    array_splice( $total_rows, $key_position, 0, $new_shipping_rows ); // splice in at position 3

    return $total_rows;
}
add_filter( 'woocommerce_get_order_item_totals', 'aspwc_split_package_total_rows', 10, 3 );

我正试图使用以下方法删除:

remove_filter( 'woocommerce_get_order_item_totals', 'aspwc_split_package_total_rows', 10, 3 );

我的自定义函数正在取代它:

add_filter( 'woocommerce_get_order_item_totals', 'custom_split_package_total_rows', 10, 3 );

function custom_split_package_total_rows( $total_rows, $order, $tax_display ) {
    if ( get_option( 'advanced_shipping_packages_display_separately', 'no' ) != 'yes' ) {
        return $total_rows;
    }

    /** @var WC_Order $order */
    $shipping_items    = $order->get_items( 'shipping' );
    $key_position      = array_search( 'shipping', array_keys( $total_rows ) );
    $new_shipping_rows = array();

    foreach ( $shipping_items as $item ) {
        $package_name = $item->get_meta( 'package_name' ) ?: str_replace( ':', '', __( 'Shipping:', 'woocommerce' ) );

        $new_shipping_rows[ 'shipping_' . $item->get_id() ] = array(
            'label' => $package_name . ':', // Package name
            'value' => aspwc_get_shipping_to_display( $item, $order, $tax_display ) . '<br/><strong>via ' . $item->get_name() . '</strong><br/><small>' . $item->get_meta( 'Items' ) . '</small>',
        );
    }

    // Remove original shipping line - Only when new rows are set (which should only happen when package names are stored)
    if ( ! empty( $new_shipping_rows ) ) {
        unset( $total_rows['shipping'] );
    }

    // Add package line(s)
    array_splice( $total_rows, $key_position, 0, $new_shipping_rows ); // splice in at position 3

    return $total_rows;
}

一切正常,但我不明白为什么 remove_filter 什么都没做。

如有任何建议,我们将不胜感激!

remove_filter 应该只有三个属性。因此,请尝试以下remove_filter代码

remove_filter( 'woocommerce_get_order_item_totals', 'aspwc_split_package_total_rows', 10 );

如果它仍然不起作用,请在里面试试 init 或 plugins_loaded 钩子。检查以下代码。

    function gs_plugins_loaded(){
        remove_filter( 'woocommerce_get_order_item_totals', 'aspwc_split_package_total_rows', 10 );
        add_filter( 'woocommerce_get_order_item_totals', 'custom_split_package_total_rows', 10, 3 );
    }
    add_action('plugins_loaded', 'gs_plugins_loaded');
