WooCommerce - 文本行在结帐页面上不断重复

Question

I want to insert "If you'd like to change your subscription, go back to Cart" on my checkout page. I inserted it in the review-order.php file, but it repeats on the checkout page even if I only inserted the line once in the document.

Does anyone know how to fix this?

I'd like to show the text at the top of the section (before the table).
Thanks in advance!

Here is the code: (the top line is what I added)

    <?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

For this purpose, it is better to use woocommerce hooks (without editing review-order.php template):

You need to use (pasting this code in the function.php file of your active child theme or theme):

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>';
}

This works perfectly (tested), no more repetition. woocommerce_checkout_before_order_review hook add something just after "Order summary" title.

You can manage styling with .return-to-cart class in your style.css file located in your active child theme or theme:

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

If your website is multilingual you can set it with gettex this way:

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>';
}

Replacing your_theme_domain by your theme slug. Like this you will be able to translate it in many languages.
