setting comments off as default for pages and custom post types?

When I create a new page, I want these two checkboxes (from the "Discussion" meta box) to appear unchecked by default.

Can this be done programmatically?

Answer 1

You can re-register the "page" post type and leave out the comments capability.

add_action( 'init', 'my_new_page_type' );

function my_new_page_type() {
    register_post_type( 'page', array(
        'labels' => array(
            'name_admin_bar' => _x( 'Page', 'add new on admin bar' ),
        ),
        'public' => true,
        'publicly_queryable' => false,
        '_builtin' => true, /* internal use only. don't use this when registering your own post type. */
        '_edit_link' => 'post.php?post=%d', /* internal use only. don't use this when registering your own post type. */
        'capability_type' => 'page',
        'map_meta_cap' => true,
        'hierarchical' => true,
        'rewrite' => false,
        'query_var' => false,
        'supports' => array( 'title', 'editor', 'author', 'thumbnail', 'page-attributes', 'custom-fields', 'revisions' ),
    ) );
}

Actual answer: original source here

function default_comments_off( $data ) {
    if( $data['post_type'] == 'page' && $data['post_status'] == 'auto-draft' ) {
        $data['comment_status'] = 0;
        $data['ping_status'] = 0;
    }

    return $data;
}
add_filter( 'wp_insert_post_data', 'default_comments_off' );

Answer 2

Re-registering the page post type is a bit excessive. remove_post_type_support is a bit easier. Combined with the answer mentioned by @developdaly, and you'll effectively turn comments off.

<?php
add_action( 'init', 'wpse48145_remove_comments', 99 );
/**
 * Removes support for comments from Pages.
 * 
 * @uses remove_post_type_support
 */
function wpse48145_remove_comments()
{
    remove_post_type_support( 'page', 'comments' );
}

Answer 3

This has/had annoyed me for a while so I did some digging around:

function wpse48145_unchecked_page_discussion () {
      if( 'page' == $_REQUEST[ 'post_type' ]  ) {
        add_filter( 'pre_option_default_comment_status', 'wpse48145_unchecked_page_discussion_filter' );
        // & if you want...
        add_filter( 'pre_option_default_ping_status', 'wpse48145_unchecked_page_discussion_filter' );
    }
}
add_action( 'load-post-new.php', 'wpse48145_unchecked_page_discussion' );

function wpse48145_unchecked_page_discussion_filter ( $val ) {
    return 'closed';
}

works as of WP 3.4.2

Answer 4

1. Go to Dashboard -> Settings -> Discussion
2. Find Default Article settings
3. Uncheck "Allow link notifications from other blogs (pingbacks and trackbacks)" and "Allow people to post comments on new articles"

These changes will not change settings for existing posts. If you want to change existing posts, do a Bulk Edit from the Dashboard -> Posts screen.

Edit

Sorry, I misread your question initially. WordPress doesn't provide a UI to set default comment status based on post type.

Note: this is a known issue.
