WP_Query() does not return all entries

Question

I have this query that returns only a few of the entries I have on the table. I have over 10 posts but this query only returns 6. Please help with suggestions

$query = new WP_Query("year=2011&monthnum=09&post_status=publish&post_type=post&orderby=post_date&order=DESC"); while ($query->have_posts()):     $query->the_post();     $title=get_the_Title();                                                                                                                       echo"<p><input type=\"checkbox\" name=\"MyArticle[]\" value=\"".get_the_ID()."\">".get_the_Title()."</p>"; endwhile;                wp_reset_query(); 

Answer 1

Try adding posts_per_page=-1 to the string of parameters passed to WP_Query.

If that value is not set, then it falls back to use the default posts per page option you have set in Settings >> Reading >> Blog pages show at most.

My guess is that this value is 6 so its returning that many posts since you did not specify a different limit.

Answer 2

$args = array(     'post_type' => 'product',     'orderby' => 'ASC',     'posts_per_page'=>-1 ); $wp_query = new WP_Query($args);
