Step by step tutorial about creating global search in your Multisite Network.
In this tutorial I am going to talk about how to print all the terms from your multisite network using just one query. It means that we are not going to use
swith_to_blog() solution, because there is some disadvantages to it.
- When you print categories or any other custom taxonomies with the help of
get_terms()it will be tough to sort them in a desired way, and usually terms are going to be displayed separated by a site (all terms from Site 1, then all terms from Site 2 etc).
- There are going to be a lot of SQL queries – for each loop iteration at least.
