I am desperately looking for some way (any way) to set default "screen options" and metabox order through the functions.php file. does anyone have any help they can provide here?

Setting the order of meta boxes on post edit pages
You will need to remove the meta boxes, and add them again in the order you want.
To disable meta boxes: (customize to your needs, look at the metabox id in the html code to know which name you should use as first parameter of the functions)
function my_remove_meta_boxes() {
remove_meta_box('postcustom', 'post', 'core');
remove_meta_box('commentsdiv', 'post', 'core');
...
}
add_action( 'admin_menu', 'my_remove_meta_boxes' );
After removing them, you can use the add_meta_box function to add them at new positions: http://codex.wordpress.org/Function_Reference/add_meta_box. The order of the meta boxes depends on the order in which you call the add_meta_box function. E.g.: with the following code snippet, the comments meta box will be before the custom fields meta box.
function my_add_meta_boxes( $post_type, $post ) {
if ( ('publish' == $post->post_status || 'private' == $post->post_status) && post_type_supports($post_type, 'comments') )
add_meta_box('commentsdiv', __('Comments'), 'post_comment_meta_box', $post_type, 'normal', 'core');
if ( post_type_supports($post_type, 'custom-fields') )
add_meta_box('postcustom', __('Custom Fields'), 'post_custom_meta_box', $post_type, 'normal', 'core');
...
}
add_action( 'add_meta_boxes', 'my_add_meta_boxes' );

Setting which columns title show up on the post list page
You need to use the filter manage_{$post_type}_posts_columns. E.g.: the following snippet will remove the comments column.
function my_remove_columns( $posts_columns ) {
unset( $posts_columns['comments'] );
return $posts_columns;
}
add_filter( 'manage_post_posts_columns', 'my_remove_columns' );
Setting the default results to be shown on the post list page
Use the filters 'edit_{$post_type}_per_page' and 'edit_posts_per_page'.
function my_edit_post_per_page( $per_page, $post_type ) {
$edit_per_page = 'edit_' . $post_type . '_per_page';
$per_page = (int) get_user_option( $edit_per_page );
if ( empty( $per_page ) || $per_page < 1 )
$per_page = 1;
return $per_page;
}
add_filter( 'edit_posts_per_page', 'my_edit_post_per_page' );
To target a specific post type:
use
add_filter( 'edit_{post type}_per_page', 'my_edit_post_per_page' );
e.g.add_filter( 'edit_post_per_page', 'my_edit_post_per_page' );
for posts,add_filter( 'edit_page_per_page', 'my_edit_post_per_page' );
for pages.or use a condition within your function. e.g.:
function my_edit_post_per_page( $per_page, $post_type ) {
if( $post_type == 'post' ) { $edit_per_page = 'edit_' . $post_type . '_per_page'; $per_page = (int) get_user_option( $edit_per_page ); if ( empty( $per_page ) || $per_page < 1 ) $per_page = 1; } return $per_page;

Sorry, maybe i did not explain myself correctly. I was referring to the meta boxes on the post edit page in the admin area as well as setting the default number of posts to display on the admin post list page. Sep 6, 2010 at 8:13

@sorich87 thank you for your response however from what I remember there was no way to specific the exact order of each metabox or was there? Maybe I should be a bit more specific. I am basically looking for various code snippets which let me pre-set various options for all users without having to login to each account. Examples: setting the exact order of meta boxes on post edit pages, setting which columns title show up on the post list page, setting the default results to be shown on the post list page... things like that. Thanks in advance. Sep 7, 2010 at 4:41

In the following example, replace {CPT}
with the post type name, like post
, page
, book
, event
, imaginary
, foobar
... So if you have a post type named event
, you would need to add a filter for get_user_option_meta-box-order_event
.
add_filter( 'get_user_option_meta-box-order_{CPT}', 'metabox_order' );
function metabox_order( $order ) {
return array(
'normal' => join(
",",
array( // vvv Arrange here as you desire
'customdiv-{CPT}',
'authordiv',
'slugdiv',
)
),
);
}
Notes:
- Along with
normal
, you can also haveside
andadvanced
- The values are comma separated div ids, you can grab by view the page source code or you can guess
- Any metabox that exists isn't included in your custom order will be added automatically at the end of your list.

1I was somewhat confused by the
{CPT}
nomenclature; to clarify, if you have a post type namedevent
, you would need to add a filter forget_user_option_meta-box-order_event
