Why is WooCommerce function not overriding the default function in child theme - php

Question

I have a child theme that I am trying to override a WooCommerce function.
WooCommerce file in plugin location: woocommerce/includes/wc-template-hooks.php. I created a new file in the same hierarchy in my child theme and it's located here: my-child-theme/woocommerce/includes/wc-template-hooks.php
My edited section is I commented out the product title in child theme:
/**
* Product Summary Box.
*
* #see woocommerce_template_single_title()
* #see woocommerce_template_single_rating()
* #see woocommerce_template_single_price()
* #see woocommerce_template_single_excerpt()
* #see woocommerce_template_single_meta()
* #see woocommerce_template_single_sharing()
*/
//add_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_title', 5 ); //commented
add_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_rating', 10 );
add_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_price', 10 );
add_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_excerpt', 20 );
add_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_meta', 40 );
add_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_sharing', 50 );
However, when I goto my product page, I still see the title.
Any idea what I am doing wrong?

Answer 1

You need to remove action woocommerce_single_product_summary to this work properly.
add_action( 'woocommerce_before_single_product', 'remove_woocommerce_single_product_summary', 10 );
function remove_woocommerce_single_product_summary() {
remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_title', 5 );
}
Just add this to your functions.php and will do the magic.
You also can try to add remove_action() out of the add_action(). Just like this...
remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_title', 15 );
...directly to functions.php
Play with it.
TIPS & TRICKS
If you want to change your HTML in the title or do anything you want, here is example:
add_action( 'woocommerce_before_single_product', 'remove_woocommerce_single_product_summary', 10 );
function remove_woocommerce_single_product_summary() {
// First, we remove it
remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_title', 5 );
// Second, we add new title
add_action( 'woocommerce_single_product_summary', 'woocommerce_my_new_title', 1 );
}
function woocommerce_my_new_title(){
echo '<h1 class="some-my-custom-classes">' . the_title() . '</h1>';
}
If your active theme does not support Woocommerce and you want to add
a Woocommerce template to your active theme, you must register
WooCommerce, or give Woocommerce features.
Check out these links for more details:
https://github.com/woocommerce/woocommerce/wiki/Declaring-WooCommerce-support-in-themes
https://docs.woocommerce.com/document/template-structure/
One important thing:
If you change the template folder within the Woocommerce plugin, there is a good chance that you will lose your settings after the plugin update. That is why it is better to work in an active theme.

Answer 2

function my_custom_action() {
echo '<p>Hello here</p>';
};
add_action( 'woocommerce_single_product_summary', 'my_custom_action', 15 );
