I am using this plugin and I need to add authors to multiple posts based on post category.
Normally without the plugin I would view all posts of a category in the WP Admin, select bulk edit, then change author. But that function is irrelevant here given multiple authors.
I assume I need to run a SQL statement to do this.
I am using the following statement to return all posts of a certain category.
SELECT * FROM wp_posts
INNER JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id)
INNER JOIN wp_term_taxonomy ON (wp_term_relationships.term_taxonomy_id = wp_term_taxonomy.term_taxonomy_id)
WHERE (wp_term_taxonomy.term_id = 23
AND wp_term_taxonomy.taxonomy = 'category'
AND wp_posts.post_type = 'post'
AND wp_posts.post_status = 'publish');
How can I add author IDs to the co-authors to the results of this query using SQL directly?
