Need to edit many posts at once in WordPress? Is the standard limit of 15 posts on the Posts Edit screen just not enough for you? Well, there is a hack you might be interested in. This involves editing the core WP files, so is not recommended as a permanent solution or for production sites… it works for me, but it might kill your cat and devastate the area around your home. You have been warned.
Check our wp-admin/includes/post.php, and find this line (it’s around line 805 in WP 2.7.1):
wp("post_type=post&what_to_show=posts$post_status_q&posts_per_page=15&order=$order&orderby=$orderby");
Change the “posts_per_page” value to whatever you see fit.
This came in handy for me on a site where I’d accumulated several thousand posts due to a rogue script, and I wanted to delete them through the GUI to take advantage of some plugin hooks, rather than just scrubbing the database.
