Now, you should have a brief understanding of built-in hooks in themes, as well as theme-specific hooks. Let's take a look at the basic steps for customizing themes using these hooks:
- Execute a directory search on the theme and identify the hooks by tracking the apply_filters and do_action functions.
- For the filters, check whether more than two parameters have been passed to the apply_filters function. The second parameter will be the variable you will be filtering, and additional parameters will be used to support the filtering process.
- If the apply_filters function contains two parameters, you can implement it by using following code:
add_filter( 'filter_hook_name', 'filter_implementation_function_name' ...
