Question

global $post; 
$cat1=get_cat_ID('test1'); 
$cat2=get_cat_ID('test2'); 
$myrecentposts = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat1,-$cat2",'showposts' => 5));
$myrecentposts2 = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat1,-$cat2"));
$myrecentpostscount = count($myrecentposts2);
echo $myrecentpostscount;

The value of the echo is 5 (the correct value should be 9). The only way I can get it to return the correct value for the post count is to change the $myrecentposts2 calculation as follows…

$myrecentposts2 = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat1,-$cat2",'showposts' => 999));

Answer 1

The WordPress codex says get_posts has a default posts_per_page value of 5.

To remove this limit use posts_per_page = -1.

To remove this limit you can use nopaging = true.
