WooCommerce - 结帐页面上的文本行不断重复

Question

我想在结帐页面上插入“如果您想更改订阅，请返回购物车”。我将它插入到review-order.php 文件中，但即使我只在文档中插入该行一次，它也会在结帐页面上重复。

有谁知道如何解决这个问题？

我想在部分顶部显示文本（在表格之前）。
提前致谢！

代码如下：（最上面一行是我添加的）

    <?php echo "<strong>If you'd like to change your subscription, go back to <a href='https://sprinly.com/cart/'>Cart</a></strong> </br>"; ?>


<?php

Answer 1

为此，最好使用woocommerce钩子（无需编辑review-order.php模板）：

您需要使用（将此代码粘贴到您的活动子主题或主题的function.php文件中）：

add_action( 'woocommerce_checkout_before_order_review', 'my_wc_checkout_before_order_review', 10, 0 );
function my_wc_checkout_before_order_review() {
    echo '<p class="return-to-cart">If you\'d like to change your subscription, go back to <a href="'. WC()->cart->get_cart_url() .'">Cart</a>.</p>';
}

这很好（已测试），不再重复。 woocommerce_checkout_before_order_review hook 在“订单摘要”标题后添加一些内容。

您可以使用位于活动子主题或主题中的 style.css 文件中的 .return-to-cart 类管理样式：

.return-to-cart{
    font-weight:bold;
}

如果您的网站是多语言的，您可以使用 gettex 进行设置：

add_action( 'woocommerce_checkout_before_order_review', 'my_wc_checkout_before_order_review', 10, 0 );
function my_wc_checkout_before_order_review() {
    echo '<p class="return-to-cart">'.__("If you'd like to change your subscription, go back to ", "your_theme_domain").'<a href="'. WC()->cart->get_cart_url() .'">'.__("Cart", "woocommerce").'.</a></p>';
}

用你的主题 slug 替换 your_theme_domain。像这样，您将能够将其翻译成多种语言。
