do_action_ref_array( 'the_post', WP_Post $post, WP_Query $query )

More Information

The ‘the_post’ action hook allows developers to modify the post object immediately after being queried and setup.

The post object is passed to this hook by reference so there is no need to return a value.

Example

function my_the_post_action( $post_object ) {
// modify post object here
}
add_action( 'the_post', 'my_the_post_action' );
