Am I using get_posts wrong?

Question

I have

<?php 
$folioPosts = get_posts(array('category_name' => 'portfolio', 'numberposts' => 3));
if ($folioPosts->have_posts()) :
foreach ($folioPosts as $folioPost) : 
setup_postdata($folioPost);
?>

<article class="col3">
  <?php if (has_post_thumbnail()) : ?>
  <p><a href="<?php the_permalink() ?>"><?php the_post_thumbnail() ?></a></p>
  <?php endif; ?>
  <p><a href="<?php the_permalink() ?>"><?php the_title() ?></a></p>
</article>

<?php
endforeach;
else :
?>
<p>No folio posts to display ...</p>
<?php endif; ?>

I am getting

Fatal error: Call to a member function have_posts() on a non-object ...

I think its because my args to get_posts are wrong. Did I do something wrong?

Answer 1

get_posts() returns an array, not a WP_Query object. If you want to use have_posts() and related functions, use a "raw" WP_Query object.

Answer 2

If you want that to work, instead of this:

if ($folioPosts->have_posts()) :

try this:

if( !empty( $folioPosts ) ) :

Also, after the foreach line and before setup_postdata, add something like this:

global $post; $post = $folioPost;
