Posts Per Page -> Per Post Type

Hi @vrandom

I got the data returning from the first query:

array(1) {
[0]=>
object(stdClass)#6075 (2) {
[“grouped_id”]=>
string(15) “398,397,392,343”
[“post_type”]=>
string(4) “news”
}
}

With regards to the primary_ as I changed my wordpress table prefix, I changed all the primary_wp to primary_foe_tableprefix etc. I dont know if this would have something to do with it:

Are you able to tell me where your spotting: So can you explain why you need data from the two tables, foe_342fj29x2_posts primary_foe_342fj29x2_posts?

$post_slug=$post->post_name;

Now on to this:

  where

Apologies, my SQL is poor!

Been fiddling for a while now, Im up to this:

News for Business Leaders:

Notice: Undefined index: cache_results in /Users/localhost/website/wp-content/themes/theme/functions.php on line 1160

I can see the pagination now though, but no posts.

Im using this query:

I dont have two post tables, your right! Dont know where that came from.

Now this:
