Get all custom post types excepted some…

Question

I stack since a few hours now and I'm sure that this is not so complicated. I would like to get all custom post types into this

$posts = query_posts( $query_string.'post_type=POST-TYPE1,POST-TYPE2,POST-TYPE3&post_status=publish&posts_per_page=-1&' );

I know that there is this function: $post_types=get_post_types('','names'); And I have some Post Types which I want to exclude. E.g. "Portfolio".

So how is it possible to get the $posts looking for all important Types?!

Thanks a lot !!

Following code generates the array to use as argument.

<?php
// Excluded CPTs. You can expand the list.
$exclude_cpts = array(
    'portfolio'
);
// Builtin types needed.
$builtin = array(
    'post',
    'page',
    'attachment'
);
// All CPTs.
$cpts = get_post_types( array(
    'public'   => true,
    '_builtin' => false
) );
// remove Excluded CPTs from All CPTs.
foreach($exclude_cpts as $exclude_cpt)
    unset($cpts[$exclude_cpt]);
// Merge Builtin types and 'important' CPTs to resulting array to use as argument.
$post_types = array_merge($builtin, $cpts);

My suggestion is to use WP_Query instead of query_posts. See When should you use WP_Query vs query_posts() vs get_posts()?.

Basically it's a wp_filter_object_list() call specifying names as output and and as operator. As you can't distinguish between portfolio and the rest by it's objects data, you'll have to do unset that one manually.

$cpts = get_post_types( array(
    'show_in_nav_menus' => false
) );
unset( $cpts['portfolio'] );
foreach ( $cpts as $cpt )
    $r[] = get_post_type_object( $cpt );

printf(
     '<pre>%s</pre><br /><pre>%s</pre>'
     // The names only
    ,var_export( $cpts, true )
     // The full post type objects
    ,var_export( $r, true )
);
