get_posts won't filter by post_type

    I’ve looked for bugs and support issues. The closest issue I found was this post here.

    I’m working with custom xml-rpc methods and using get_posts as follows:

    // construct query
    $params = array(
	'post_type' => 'page',
     	'numberposts' => $numberposts,
    	'offset' => $offset
    	);
    $posts = get_posts($params);

    The returned value is an array of both posts and pages, though the other parameters work correctly. The resultant value of $posts is unchanged if I switch ‘post_type’ to => ‘post’ or omit it entirely (function reference claims to default to ‘post’).

    I’ve also tried a single string of args, but no difference:
    get_posts('post_type=post');

    If there’s no solutions I’ll

    Hey, did you find a solution?

    I never found anything that corrected the faulty get_posts(). So I had to create my own workaround:

    This code shows only posts and filters out the pages that incorrectly return from the get_posts() method by continuing to increment the offset until the full count is reached of just posts. 

    // construct query
    $params = array(
    	'numberposts' => $numberposts,
    	'offset' => $offset,
    	'post_type' => 'post'    // doesn't work?
    	);
    $posts = get_posts($params);

    // filter out pages
    $pageCount = $pages = 0;
    $filteredPosts = array();
    do
    {
        $pageCount = 0;
	foreach($posts as $p)
	{
	    if (strcmp($p->post_type, 'page') == 0)
	    	++$pageCount;
	    else
	    	array_push($filteredPosts, $p);
	}
	if ($pageCount != 0)
	{
	    $offset += $numberposts;
	    $numberposts = $pageCount;
	    $params['numberposts'] = $numberposts;
	    $params['offset'] = $offset;
	    $posts = get_posts($params);
	}
	$pages += $pageCount;
    } while ($pageCount != 0);

    // Final array
    return $filteredPosts;

    Hey, this is what I am doing at the moment too. But I thought there would be a “better” solution. Thanks anyway for your reply

    I was just having the same problem with the get_posts function. What I ended up doing is using WP_Query instead, which does exactly what get_posts should be doing as well.

    Here is a simplified version of my code:

    //Setting up the query arguments
$myArgs = array( 'numberposts' => -1, 'post_type' => 'my_post_type', 'orderby' => 'title', 'order' => 'ASC' );
//The following line doesen't work
//$myPages = get_posts( $myArgs );
//This does the job
$myQuery = new WP_Query( $myArgs ); 

//Looping through the posts
while ( $myQuery->have_posts() ) : $myQuery->the_post();
	echo '<a href="' .  get_permalink() . '" title="' . get_the_title() . '">' . get_the_title() . '</a><br />';
endwhile;

// Reset Post Data
wp_reset_postdata();
