I realize this is nearly a year later, but this is how I set a default.
The site I am working on has several custom post types that are being used for several things, three of which are “blogs”. There is another that is a ‘widget-post’ that is used for repeating items in different places, and it’s one of these I needed to include by default in my blogs.
I added a custom field to the widget-posts that allows one to be flagged as a default. I then set up the below function that will insert meta data via ‘save_post’, which is called upon when creating a new post. It will also retroactively save items that are edited.
/**
* Function will set the default Editorial Team description post if it isn't set at all
* This sets up the default upon creating a post
*
* @uses The $blog_post_types array, which has to have all of the blog post types listed in it
*/
function jp_blog_save_post( $post_id ) {
// get our post types
global $post_type, $blog_post_types;
// if it doesn't match, exit
if( ! in_array( $post_type, $blog_post_types ) )
return;
// get the meta data
$editorial_staff_post = get_post_meta( $post_id, 'editorial_staff_post', true );
// if it isn't set, set it
if( $editorial_staff_post == '' ) {
// set up args
$args = array(
'post_type' => 'widget-post',
'meta_key' => 'default_editorial_staff_description',
'meta_value' => 1,
);
// get the post(s) that have the checkbox checked
$wpost = get_posts( $args );
// set it as a default for this post
update_post_meta( $post_id, 'editorial_staff_post', $wpost[0]->ID );
}
}
add_action( 'save_post', 'jp_blog_save_post' );
Hope this helps anyone else that runs into this. I’m also sure it can be done with multiple choices.
