Using multi-tenant WordPress to simplify development
- 1. Using multi-tenant WordPressto simplify development (among other things)

- 3. • WordPress devat WashU since December 2011 • “Professional code monkey, amateur grease monkey.” • WordCamp STL organizer • Luckiest WordPress dev in the world! About Me
- 4. December 2011 • 0WordPress sites • 1,000s of SharePoint sites (OK, maybe an exaggeration but who cares about SP) • 3 Devs July 2013 • 100s of WordPress Sites hosted locally • 100s of WordPress Sites hosted on CampusPress • 0 SharePoint sites (OK, maybe an exaggeration but who cares about SP) • >25 Devs, designers, content strategists, project managers, etc… WordPress@WashU
- 5. In the beginning…wecoded every site like it was the only site we were doing, which meant: • Blank Slate: we didn’t even use Bootstrap • No Plugins: wrote all functionality into the theme • No Version control: ¯_(ツ)_/¯ • No Access: WP Easy Uploader FTW (?) WordPress@WashU
- 6. Since then, we’vegotten smarter: • Unified theme: one theme for CP, Med School, and Main Campus • SO Many plugins: 34 on medicine (but only 17 on wustl.edu) • SO Much version control: GitHub, Bitbucket, BitBucket server • No Access: Still no SFTP/SSH access, but that’s OK WordPress@WashU
- 7. While we mayhave a unified theme, there are still “one off”s that we handle, plus child themes and legacy sites. We have over 30 “in-house” plugins that are used on at least one site. Multiply X by Y and you just get a headache Developing for WordPress@WashU
- 8. First attempt –let’s not talk about that Second attempt – Symlinks to Symlinks in Symlinks (OK, maybe not THAT bad) Third (and so far final) attempt – Multitennant!!! Developing for WordPress@WashU

- 11. Multitenant ≠ Multisite •Per site wp-config file • Multiple Databases vs Single Database • One set of core files, independent uploads (or entire wp-content folder) Multitenant 101
- 12. N.B. I cameup with the term “landlord” to describe the main set of WordPress Core files Multitenant 101
- 13. • April 2014- WordPress 3.9 introduced symlinking for plugins which was the final component needed for general use • There were articles and “hacks” to do it before, but don’t be this guy: Multitenant 201 Or this guy
