如何使 woocommerce 面包屑的最后一项可点击？

Question

出于某些原因，我需要面包屑导航的最后一项链接到当前页面。我看到了一些例子： woocommerce_breadcrumb_defaults, woocommerce_breadcrumb_home_url, woocommerce_breadcrumb_main_term, woocommerce_breadcrumb_product_terms_args, 但他们都没有帮助。我该怎么办？

Answer 1

首先，您必须将 breadcrumb.php 模板从插件覆盖到您的主题。按照以下步骤操作。

从

复制breadcrumb.php文件

`wp-content/pluings/woocommerce/templates/global/breadcrumb.php`

并上传到此路径。

`wp-content/themes/your-active-theme-name/woocommerce/global/breadcrumb.php`

现在您将在 breadcum.php 中看到这样的代码

<?php
/**
 * Shop breadcrumb
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/global/breadcrumb.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files, and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see         https://docs.woocommerce.com/document/template-structure/
 * @package     WooCommerce\Templates
 * @version     2.3.0
 * @see         woocommerce_breadcrumb()
 */

if ( ! defined( 'ABSPATH' ) ) {
    exit;
}

if ( ! empty( $breadcrumb ) ) {

    echo $wrap_before;

    foreach ( $breadcrumb as $key => $crumb ) {

        echo $before;

        if ( ! empty( $crumb[1] ) && sizeof( $breadcrumb ) !== $key + 1 ) {
            echo '<a href="' . esc_url( $crumb[1] ) . '">' . esc_html( $crumb[0] ) . '</a>';
        } else {
            echo esc_html( $crumb[0] );
        }

        echo $after;

        if ( sizeof( $breadcrumb ) !== $key + 1 ) {
            echo $delimiter;
        }
    }

    echo $wrap_after;

}

更改此行

if ( ! empty( $crumb[1] ) && sizeof( $breadcrumb ) !== $key + 1 ) {

有了这个

if ( ! empty( $crumb[1] ) && sizeof( $breadcrumb ) !== $key ) {

完整代码如下所示

<?php
/**
 * Shop breadcrumb
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/global/breadcrumb.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files, and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *

 * @package     WooCommerce\Templates

 */

if ( ! defined( 'ABSPATH' ) ) {
    exit;
}

if ( ! empty( $breadcrumb ) ) {

    echo $wrap_before;

    foreach ( $breadcrumb as $key => $crumb ) {

        echo $before;

        if ( ! empty( $crumb[1] ) && sizeof( $breadcrumb ) !== $key ) {
            echo '<a href="' . esc_url( $crumb[1] ) . '">' . esc_html( $crumb[0] ) . '</a>';
        } else {
            echo esc_html( $crumb[0] );
        }

        echo $after;

        if ( sizeof( $breadcrumb ) !== $key + 1 ) {
            echo $delimiter;
        }
    }

    echo $wrap_after;

}

已测试并有效。
