How to restore WordPress to a different domain

by

In this podcast I will show you how to restore a WordPress site that we’ve backed up in the previous show. In particular, we will restore a remote website to our local system first, and because it’s a rather tricky process we’ll also install it on another remote host.

How to fix “this class is not key value coding-compliant” after accidentally adding an IBOutlet instead of an IBAction

by

It has happened to us all: you’re in a storyboard, you’re using the Assistant Editor, you want to control-drag from a button into your code and create an action.

How to bulk delete posts in WordPress with MySQL

by

mysqlUsually deleting several posts at once is not a problem thanks to the bulk delete options in WordPress. Those queries however rely on a single delete each, initiated by PHP loop. That’s fine if you’re deleting up to about 100 posts at a time.

But it’s not when you have thousands of posts to delete. I’ve come across installations with hundreds of thousands of posts which have often been created automatically – and there comes the time when you need to clean things up and prune that massive database.

Deleting 100.000 posts is impossible from within WordPress: it puts a huge load on your server, it takes forever, and besides WordPress will time out after about 200 posts.
