I am writing a short script that is designed to generate a random post. I also have a session where I keep track of the post they have been to already. I put these pages in a comma delimited variable and attempted exclude them. Here is my sql statement:
Here is what it looks like in PHP:
$randomPost = $wpdb->get_var("SELECT guid FROM $wpdb->posts WHERE post_type = 'post' AND post_status = 'publish' AND ID <> ($pageids) ORDER BY rand() LIMIT 1");
Here is what it looks like when the variables are gone:
SELECT guid FROM hb_posts WHERE post_type = 'post' AND post_status = 'publish' AND ID <> (1,15,13,20,17,11,5,9,3,0) ORDER BY rand() LIMIT 1
I can get the code to work fine if I exclude just one post, so the error is in my (1,1,5,20....).
