post-list multiple categories bug?

    I’m trying to display a list of posts from multiple categories. It works with the syntax category=”slug1,slug2″, but if I use the category IDs (category=1,2 or also tried category=”1,2″) the result is always “No posts could be found that matched the specified criteria.” Calling one category by ID works fine.

    Thanks for the note. This is sort of a bug in the plugin, as a result of trying to make things easier on users. Basically, the way the plugin works is:

    If the category attribute is a number, it assigns it to the cat_id argument when it runs the query.
    If the category attribute is not a number, it assigns it to the category_name argument when it runs the query.

    Since “1,2” is technically not *a* number, it assigns that to the category_name argument.

    In order to get around this, you will probably need to make the following adjustments:

    In your theme’s functions.php file (or in a mu-plugin, if you understand how those work), add the following:

    <?php
add_filter( 'post-content-shortcodes-defaults', 'add_cat_id_arg_to_pcs' );
function add_cat_id_arg_to_pcs( $defaults=array() ) {
    $defaults['cat_id'] = null;
    return $defaults;
}
?>

    Then, in your shortcode, use cat_id="1,2" instead of category="1,2" and see if that works. Thanks.
