[wp-testers] A Question About 2.7/2.8 argument system

[DD32]

cat=1,2,3,4,5 style arguements are WP exploding the value by commas as you
thought

There are 2 ways to call arguements in WP, Via a string, as you are doing,
or via an array:

query_posts('showposts=2');
is identical to:
query_posts( array( 'showposts' => 2 ) );

However, I do not think that query of yours above about showposts[post1] and
showposts[post2] would work as you expect it to.. Yes,  It'll convert it to
an array, however, WordPress converts it back to a int, as that param is
only designed to limit the number of results retuened.

Taken directly from wp-includes/query.php (line ~1200) is this:
        $array_keys = array('category__in', 'category__not_in',
'category__and', 'post__in', 'post__not_in', 'tag__in', 'tag__not_in',
'tag__and', 'tag_slug__in', 'tag_slug__and');

Those are the only keys which WP expects an array for, others which deal
with Categories and Tags need to be passed as a string, ie: array('cat' =>
'1, 2, 3), If you were trying to only show 2 known posts, then you'd be
after array('post__in' => array(1, 2));
