Illustrate how to check the value of ```post__in``` before it is used to construct a new ```WP_Query``` object.
<?php | |
$my_posts = false; | |
$my_post_ids = mytheme_get_special_post_ids(); | |
if ( ! empty( $my_post_ids ) ) { | |
$my_posts = new WP_Query( array( | |
'post__in' => $my_post_ids, | |
'post_status' => 'publish', | |
'posts_per_page' => 10, | |
'no_found_rows' => true, | |
) ); | |
} | |
if ( $my_posts ) { | |
// Do something with the posts here. | |
} |
