get_posts not working on homepage?

Question

I have a simple custom shortcode plugin where you give it a tag and it'll display the titles of all the posts with that tag.

e.g. In my post if I type "[listposts tag=oct-2011]" it will output the titles of all posts tagged as "oct-2011".

This plugin has been working fine for me until the v3.2 upgrade.

Now, it still works fine when the post which uses the shortcode is viewed on its own. But when that post is viewed on the homepage, the get_posts() query returns 0 results.

What do I need to do to fix the plugin?

Here is the relevant code:

function listposts($atts) {
    $atts = shortcode_atts(
        array(
            'tag' = 'jan-2011',
            'numberposts' = '-1',
            'orderby' = 'post_date',
            'order' = 'asc',
            'post_status' = 'any' ),
        $atts);

    $catposts = get_posts($atts);
    $out = '';
    foreach ($catposts as $single) {
        $out .= $single->post_title;
    }

    return $out;
}

Answer 1

For get_posts argument suppose to be numberposts not posts_per_page and you were passing as string make it integer try it, this may help you

function listposts($atts) {

$atts = shortcode_atts( array( 'tag' => 'jan-2011', 'numberposts' => -1, 'orderby' =>  'post_date', 'order' => 'asc', 'post_status' => 'any' ), $atts );
$catposts = get_posts( $atts );
$out = '';
foreach ( $catposts as $single ) 
    {
        $out .= $single->post_title."<br />";
    }
return $out;
}

add_shortcode( 'list', 'listposts' );

I checked your code locally, it works fine...

function listposts($atts) {
    $atts = shortcode_atts(array('tag' => 'lorem', 'posts_per_page' => -1, 'orderby' =>  'post_date', 'order' => 'asc', 'post_status' => 'any'), $atts);
    $catposts = get_posts($atts);
    $out = '';
    foreach ($catposts as $single) 
        {
            $out .= $single->post_title."<br />";
        }
    return $out;
    }

    add_shortcode('list', 'listposts');

Please recheck if you're entering the shortcode in the visual editor's HTML mode.
