Revise your DB query
-
Thanks for this plugin. It’s a huge timesaver.
However, as another user pointed out, it didn’t pre-populate with my existing categories.
I dug through the code and realized that you had your DB prefixes hard coded (and my site has custom prefixes.)
Here’s the fix, in case you want to update your code.
$q = "SELECT $wpdb->terms.'name', $wpdb->terms.'term_id' FROM $wpdb->term_relationships INNER JOIN $wpdb->term_taxonomy ON ($wpdb->term_relationships.'term_taxonomy_id' = $wpdb->term_taxonomy.'term_taxonomy_id') INNER JOIN $wpdb->terms ON ($wpdb->term_taxonomy.'term_id' = $wpdb->terms.'term_id') INNER JOIN $wpdb->posts ON ($wpdb->term_relationships.'object_id' = $wpdb->posts.'ID') WHERE ($wpdb->posts.'ID' = $postid)";
