excluding certain categories from the read related posts in wordpress

Question

I have setup my Read related posts sections to show up 4 posts of the same category. Say, I've 7 Categories - cat1, cat2, cat3, cat4,...,cat7. I would like to exclude posts under cat6 and cat7 from showing up posts in the read related post section. Please suggest me any ideas on how to get this done.? Any help in this regard would be greatly appreciated. Thank you in advance.

Note: The wordpress theme i'm using is typology, which gives me option only to show up read related posts according to category but there is no option for excluding category.

Answer 1

$arg = array('posts_per_page'=>-1, 'orderby'=>'title', 'order'=>'asc', 'category__not_in' => array(6,7) );
$loop = new WP_Query($args); 

Answer 2

是的，我们使用的是类别ID array(catID,catid) （ array(catID,catid) ），如果您感到困惑，则可以使用下面的另一种方法。

$arg = array('posts_per_page'=>-1,'cat' => -$categoryID );
