# WP_CLI::add_wp_hook()
|
|
|
|
Add a callback to a WordPress action or filter.
|
|
|
|
***
|
|
|
|
## Usage
|
|
|
|
WP_CLI::add_wp_hook( $tag, $function_to_add, $priority = 10, $accepted_args = 1 )
|
|
|
|
<div>
|
|
<strong>$tag</strong> (string) Named WordPress action or filter.<br />
|
|
<strong>$function_to_add</strong> (mixed) Callable to execute when the action or filter is evaluated.<br />
|
|
<strong>$priority</strong> (integer) Priority to add the callback as.<br />
|
|
<strong>$accepted_args</strong> (integer) Number of arguments to pass to callback.<br />
|
|
<strong>@return</strong> (true) <br />
|
|
</div>
|
|
|
|
|
|
***
|
|
|
|
## Notes
|
|
|
|
`add_action()` without needing access to `add_action()`. If WordPress is
|
|
already loaded though, you should use `add_action()` (and `add_filter()`)
|
|
instead.
