Applying Changes To Wordpress Child functions.php - php

Question

I need to change various words on the checkout page using Avada and Woocomerce. I want to change them using the child themes function.php. I found where the words are located in various .php files such as review-order.php.
So say I wanted to change the word 'Subtotal' to '小計'. I can change it easily in the review-order.php but I want to do it in the child function.php so it remains when I update. I can't figure out how to hook it etc
The code for review-order.php is below, how would I code in the child function.php in order to change this word? If I can see how to do it once, I can do it again for all the other words.
<?php
/**
* Review order table
*
* #author WooThemes
* #package WooCommerce/Templates
* #version 2.3.0
*/
if ( ! defined( 'ABSPATH' ) ) {
exit;
}
?>
<table class="shop_table woocommerce-checkout-review-order-table">
<thead>
<tr>
<th class="product-name"><?php _e( 'Product', 'woocommerce' ); ?></th>
<th class="product-total"><?php _e( 'Total', 'woocommerce' ); ?></th>
</tr>
</thead>
<tbody>
<?php
do_action( 'woocommerce_review_order_before_cart_contents' );
foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
$_product = apply_filters( 'woocommerce_cart_item_product', $cart_item['data'], $cart_item, $cart_item_key );
if ( $_product && $_product->exists() && $cart_item['quantity'] > 0 && apply_filters( 'woocommerce_checkout_cart_item_visible', true, $cart_item, $cart_item_key ) ) {
?>
<tr class="<?php echo esc_attr( apply_filters( 'woocommerce_cart_item_class', 'cart_item', $cart_item, $cart_item_key ) ); ?>">

$thumbnail = apply_filters( 'woocommerce_cart_item_thumbnail', $_product->get_image(), $cart_item, $cart_item_key );

echo $thumbnail;
else
printf( '%s', $_product->get_permalink(), $thumbnail );
?>
</span>

do_action( 'woocommerce_review_order_after_cart_contents' );

Currently the child functions.php looks like this:
<?php
function theme_enqueue_styles() {
wp_enqueue_style( 'avada-parent-stylesheet', get_template_directory_uri() . '/style.css' );
}
add_action( 'wp_enqueue_scripts', 'theme_enqueue_styles' );
function avada_lang_setup() {
$lang = get_stylesheet_directory() . '/languages';
load_child_theme_textdomain( 'Avada', $lang );
}
add_action( 'after_setup_theme', 'avada_lang_setup' );
<?php
Thanks for your help everyone!

Answer 1

As of now there is no particular hook available to change that text. You will have to change it directly in the review-order.php. But before making any changes to woocommerce's template files, make sure that you copy the template files into your child theme folder. Location of the template files should be.
"your-child-theme/woocommerce/"
What ever changes you make into the woo's template files (in your child theme) will remain even after you update the parent theme or woocommerce version.
Hope this helps.
