Disable comments on all posts/pages

Question

Is there a quick way to disable all comments on all posts and pages. I know that you can go into the dashboard under posts, click edit, and Do Not Allow, under comments. Is that the only way?

Answer 1

The check if comments are enabled is performed by comments_open() function.

You can make it always return false with something like this:

add_filter('comments_open`, '__return_false');

Other way would be to make comments available to only registered users (that is if you don't have open registration) in Settings > Discussion.

Answer 2

Not including the comment-form in your theme also works (that's what I usually do).

Answer 3

I have write an plugin for this job. https://github.com/bueltge/Remove-Comments-Absolutely

WordPress has on many different points jobs and views for comments, if you will not use all this, use the plugin or customize the source for your requirements.
