How Do You Write a Syntactically Correct WooCommerce Hook?

[Dominic]

Is there any specific rule for writing a syntactically correct WooCommerce hook?

[Liam Forbs]

WooCommerce hooks let you expand the default WooCommerce file’s content without altering the core code. The use of WooCommerce hooks allows for greater shop flexibility. They let you add and filter minuscule details to the pages and operations of your WooCommerce store.

The correct possible way of writing both action and filter-type WooCommerce hooks is to

• Name the hook
• Name the function

Hooks can be identified by the “ShowHook” plugin after that we need to define the function.

Syntax of both the filters are:

<span style=”text-decoration: underline;”>Action Hook</span>:

Fn defined as – function your_action_hook_call_back_function(){

….
Code
….
}

<span style=”text-decoration: underline;”>Filter Hook</span>:

Fn defined as – function your_filter_hook_call_back_function($data){

…

Code that modifies $data

Returns $data

}

There must be a return of value for filter hooks.
