Snippet: Related Posts by Specific ID’s
This snippet will add a new setting where you can enter the exact ID's for items to display in the related posts section of your blog.
// Add related items setting for standard posts
add_filter( 'wpex_metabox_array', function( $array, $post ) {
if ( 'post' == $post->post_type ) {
$array['main']['settings']['related_post_ids'] = array(
'title' => __( 'Related Posts', 'total' ),
'description' => __( 'Comma seperated ID\'s for related items', 'total' ),
'id' => 'related_post_ids',
'type' => 'text',
);
}
// Return fields
return $array;
}, 40, 2 );
// Alter related items if the related_post_ids meta field is set
// NOTE: for custom post types use the "wpex_related_{$post_type}_args" filter instead of "wpex_blog_post_related_query_args".
add_filter( 'wpex_blog_post_related_query_args', function ( $args ) {
if ( $related = get_post_meta( get_the_ID(), 'related_post_ids', true ) ) {
$args[ 'category__in' ] = null;
$args[ 'post__in' ] = explode( ',', $related );
}
// Return args
return $args;
} );
