showposts VS posts_per_page. showposts works perfect but deprecated!


I'm unable to substitute posts_per_page with showposts in order to limit the number of posts returned in a list. When I use showposts, the resulting menu list is correctly displayed according to the number of posts I specify in the showposts limiter. However, when I use posts_per_page, the post limiter number appears to be irrelevant. The resulting list shows all posts, exceeding the limiter count.


This works perfectly:

$myrecentposts = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat,-$catHidden",'showposts' => $cb2_recent_count)); foreach($myrecentposts as $idxrecent=>$post) {

However, when I sub in posts_per_page, this DOES NOT work...

$myrecentposts = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat,-$catHidden",'posts_per_page' => $cb2_recent_count)); foreach($myrecentposts as $idxrecent=>$post) {

*I'm only trying to get posts_per_page to work because I understand that showposts has been deprecated.


showposts <strong>is</strong> deprecated. However, posts_per_page is for use with query_posts(), or more specifically, WP_Query::query().

numberposts is the equivalent argument for get_posts().

NOTE: I removed my original answer concerning incorrect handling of arguments inside get_posts().

posts_per_page is not a valid argument for get_posts() for semantic reasons, since it suggests the idea of <strong>pagination</strong>, something which get_posts() does not support.

For clarity, and on behalf of @RichardM's comment, here's the skinny I originally wrote;

<hr />

It's down to how get_posts() parses the arguments before passing them on to WP_Query.

I've cut it down to the real basics here;

function get_posts($args = null) { $defaults = array('numberposts' => 5); $r = wp_parse_args($args, $defaults); if (!empty($r['numberposts'])) $r['posts_per_page'] = $r['numberposts']; $get_posts = new WP_Query; return $get_posts->query($r); }

See how numberposts overwrites posts_per_page, not accounting the condition that posts_per_page is being passed?


There is a bug : <a href="http://core.trac.wordpress.org/ticket/15150" rel="nofollow">http://core.trac.wordpress.org/ticket/15150</a> it is fixed in 3.1
