Articles submitted to Facebook don't match /feed/instant-articles

I was just getting ready to exclude some Custom Post Types also.

Could it be a cache thing? As in, Facebook scanned the feed when the CPT posts were there and just kept them?

No, because it showed brand new articles added since i modified the plugin to exclude CPTs ..

??

pr0fess0r did you use
this method?

I used a similar technique in feed-template.php:

$type=get_post_type(get_the_id());
if($type<>'post'){
 continue;
}

You probably already know that you’ll lose that if/when (big question) they ever update the plugin…

Yup I’ll have to merge the differences of any new version into my hacked plugin… a hassle :/

Ugh. Wish there was a better way, struggling with this also on another topic. You’d think the plugin could make this easier…

pr0fess0r I was able to get this to work, at least the feed is correct, don’t know what it will look like when Facebook pulls it (i.e. your original problem) but this might at least get it out of the plugin hack and into your functions.php:

function filter_ia_post_types($query) {
  if (defined('INSTANT_ARTICLES_SLUG') && $query->is_main_query() && $query->is_feed(INSTANT_ARTICLES_SLUG)) {

	$posttypequery = array(
			'post_type' => array( 'post' )
	);

	$query->set( 'post_type', $posttypequery );

	}
}
add_action( 'pre_get_posts', 'filter_ia_post_types' );

If you want more than one type of post, change the array as follows:

'post_type' => array( 'post', 'article' )

Hope that helps, as I said I’m not sure it will fix your original problem though ??
