# "invalid post type" error with dropdown menu?

* Hey – I love this plugin & want to use it on a multisite, but I’ve hit a major
problem. I’m using a function which gives a dropdown category menu when a user
selects new post. This makes them choose a category BEFRORE the post is created.
The problem is that adminimize is causing an “invalid post type” error. I disabled
all other plugins & I’ve tried all different settings but result is the same.
* PLEASE PLEASE PLEASE take a look at the code I’m using in functions.php and give
me an idea why adminimize hates it… thanks!
* ‘//ADD DROPDOWN MENU TO CHOOSE NEW POST CATEGORY (CHOOSE THE CAT ID’S YOU WANT
TO APPEAR)
add_filter( ‘load-post-new.php’, ‘wpse14403_load_post_new’ ); function
wpse14403_load_post_new() { $post_type = ‘post’; if ( isset( $_REQUEST[‘post_type’])){
$post_type = $_REQUEST[‘post_type’]; } // Only do this for posts if ( ‘post’ !
= $post_type ) { return; } if ( array_key_exists( ‘category_id’, $_REQUEST ) ){
add_action( ‘wp_insert_post’, ‘wpse14403_wp_insert_post’ ); return; } // Show
intermediate screen extract( $GLOBALS ); $post_type_object = get_post_type_object(
$post_type ); $title = $post_type_object->labels->add_new_item; include( ABSPATH.‘
wp-admin/admin-header.php’ ); $dropdown = wp_dropdown_categories( array( ‘orderby’
=> ‘name’, ‘include’ => ‘3, 4’, ‘name’ => ‘category_id[]’, ‘hide_empty’ => false,‘
echo’ => false, ) ); $category_label = __( ‘Create New’ ); $continue_label =
__( ‘Continue’ ); echo << {$title}
