Exception or error:
Is this possible, I couldn’t find the question asked anywhere on the web.
If you had a list of posts by their slug, example:
$postslugs = array("page-one","page-two","page-three");
And you wanted to create a single query to find all these specific pages:
$args=array(
'post__not_in' => array($post->ID),
'posts_per_page'=> -1,
'post_type' => 'customtype',
'post_status' => 'publish',
'pagename' => $postslugs
);
$my_query = new wp_query( $args );
The result should come back with the three pages. This of course would not work the way it’s written now. Is this possible?
How to solve:
If you take a look at the documentation for the WP_Query() class, specifically the Post & Page Parameters section, you’ll see it has a handy parameter called post_name__in which takes an array of post_name (aka slugs). Also, are you sure you need to use post__not_in (and maybe posts_per_page since you’re defining an array of slugs to get already?
$names = array( 'page-one', 'page-two', 'page-three' );
$query_args = array(
'posts_per_page' => -1,
'post_type' => 'customtype',
'post_status' => 'publish',
'post_name__in' => $names
);
$my_query = new WP_Query( $query_args );
