Fire a hook programmatically

Question

Is it possible to fire a wordpress hook programmatically? Specifically I'd like to have control of wp-insert-post.

Answer 1

To fire a hook you can use following functions:

1. do_action - executes a hook created by add_action.
2. do_action_ref_array - execute functions hooked on a specific action hook, specifying arguments in an array. This function is identical to do_action, but the arguments passed to the functions hooked to $tag are supplied using an array.

If you want to apply filters, you can do it by calling apply_filters function.
