WordPress Codex: Function Reference/comments open

This Conditional Tag checks if comments are allowed for the current Post being processed in the WordPress Loop. This is a boolean function, meaning it returns either TRUE or FALSE.

Yes, it is ?? Can’t tell you status on a page if you don’t say which page. But if it’s used on a post, I think that gets passed through.

Thanks for your answer.

In the comments.php of Twenty Eleven for example, the function is called without any parameters.

<?php
    /* If there are no comments and comments are closed, let's leave a little note, shall we?
     * But we don't want the note on pages or post types that do not support comments.
     */
    elseif ( ! comments_open() && ! is_page() && post_type_supports( get_post_type(), 'comments' ) ) :
?>
    <p class="nocomments"><?php _e( 'Comments are closed.', 'twentyeleven' ); ?></p>
<?php endif; ?>

Because it’s included in the single.php template file and called, specifically, FROM that post. If you tried to just show the comments of any post on a separate page (i.e. NOT the post page) you would need to specify the post ID.

Thanks again for your answer.

Alright, but in certain circumstances the parameter is optional. In my opinion, that should be made clear in the Codex.

No, because it’s still required. The twenty ten theme is passing that data through, even though you can’t see it.

Think of it this way ‘None = the page I’m on.’

Well, I actually understand, what you’re saying. But comments_open() is a function call without parameters. You agree with that, don’t you?

Kind of ??

Yes it’s a function call without any inserted parameters, so it DEFAULTS to comments_open(none), which means ‘This page’ ?? If there’s no value, it puts one in for you.

Anyway, thank you very much for your patience. ??

Have a good day, evening or night, wherever you are.
