Can you have duplicate hook names?

[chunkford]

do_action( 'quick_edit_custom_box' ... can be found in the below files:

class-wp-posts-list-table.php - Line 1743
class-wp-terms-list-table.php - Line 616

I'm querying it as one has 2 (class-wp-posts-list-table.php) inputs while the other has 3 (class-wp-terms-list-table.php)

This fills the debug.log with errors when you want to use the hook in in class-wp-terms-list-table.php as the class-wp-posts-list-table.php hook produces Missing argument and Undefined variable errors.

Thanks for the report, @chunkford!

The short answer is that yes you can have duplicate hook names (as noted by the line preceding the action in class-wp-terms-list-table.php).

However, it is indeed a bug that the two instances of this hook pass different parameters. We're already tracking that issue (along with others) in #38462.
