1. #CustomizeWoo
WooCommerce
Hooks: Actions

2. #CustomizeWoo
WordPress Actions
“ Actions (add_action) are hooks that add
functionality to WordPress, Theme & Plugins
at specific execution times
or in a specific template position ”

3. #CustomizeWoo
do_action
❏ WordPress, Theme & Plugins
(WC) code provides do_action
calls
❏ No do_action, no add_action!
❏ Types: Execution (e.g.
‘save_post’) vs Position (e.g.
‘woocommerce_before_cart’)

4. #CustomizeWoo
do_action Syntax
❏ string: name of hook
❏ arguments: variables
you can reference in
your function

5. #CustomizeWoo
add_action Syntax
❏ string: name of hook
(from do_action)
❏ your function name
❏ priority = 10
❏ number of arguments
(from do_action) = 1

6. #CustomizeWoo
do_action, add_action, function Syntax

7. #CustomizeWoo
Actions: Benefits
❏ Help us “extend” and add
functionalities without
overriding WP, Theme,
Plugins
❏ Easy to find AND
(NotePad++) search
❏ Easy to enable / disable
❏ Easy to debug (short)

8. #CustomizeWoo
Working with WC Actions: Checklist
1. Project Specs e.g. “Need to add HTML above Cart”
2. Search for hooks @ Cart or use Hooks Visual Guide
3. Find hooks in the right position:
do_action( 'woocommerce_before_cart' );
1. Create add_action & function:
add_action( ‘woocommerce_before_cart’,’add_HTML’ );
function add_HTML () {
echo ‘This will show above the cart’;
}

9. #CustomizeWoo
Adding HTML Through Actions
add_action( ‘woocommerce_before_cart’,’add_HTML’ );
function add_HTML () {
echo ‘<h3>This will show above the <a href=”#”>cart</a></h3>’;
}
____________________________________________________
add_action( ‘woocommerce_before_cart’,’add_HTML’ );
function add_HTML () {
?>
<h3>This will show above the <a href=”#”>cart</a></h3>
<?php
}

10. #CustomizeWoo
Declaring PHP Globals
add_action( 'woocommerce_single_product_summary',
'bbloomer_product_sold_count', 11 );
function bbloomer_product_sold_count() {
global $product;
$units_sold = get_post_meta( $product->id, 'total_sales',
true );
echo ‘<p>Units Sold: ‘ . $units_sold . ‘</p>’;
}

11. #CustomizeWoo
Removing WC Template Actions
add_action( 'woocommerce_single_product_summary',
'woocommerce_template_single_price', 10 );
remove_action( 'woocommerce_single_product_summary',
'woocommerce_template_single_price', 10 );
