Sites Share Plugins and Themes, Have Separate Content

This flow shows how WordPress multisite is enabled, configured, and used to manage multiple sites sharing one installation.

Execution Sample

Wordpress

<?php
// Enable multisite
define('WP_ALLOW_MULTISITE', true);
// After setup, add network constants
define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', false);
?>

This code enables multisite and sets up network constants for a subdirectory-based multisite.

Execution Table

Step	Action	File Edited	Result	Notes
1	Add define('WP_ALLOW_MULTISITE', true);	wp-config.php	Multisite option enabled in Dashboard	Allows Network Setup menu to appear
2	Go to Tools > Network Setup	Dashboard	Network Setup screen appears	Choose subdomain or subdirectory
3	Fill network details and submit	Dashboard	Instructions to update files shown	Shows code snippets for wp-config.php and .htaccess
4	Add network constants and rewrite rules	wp-config.php and .htaccess	Multisite network activated	Defines MULTISITE, SUBDOMAIN_INSTALL, and rewrites

Key Moments - 3 Insights

Why do I need to add code to both wp-config.php and .htaccess?

The execution_table rows 3 and 4 show that wp-config.php sets multisite constants, while .htaccess controls URL rewriting needed for multisite to work.

What is the difference between subdomain and subdirectory setup?

Row 2 in execution_table shows you choose subdomain (site1.example.com) or subdirectory (example.com/site1) during setup, affecting URL structure.

Do all sites share content?

Row 6 explains sites share plugins and themes but have separate posts and pages, so content is unique per site.

Full Transcript

To set up a WordPress multisite network, first enable multisite by adding a line in wp-config.php. Then, in the WordPress Dashboard, go to Tools and select Network Setup. Here, you choose whether your sites use subdomains or subdirectories. After submitting, WordPress shows code snippets to add to wp-config.php and .htaccess files. Adding these activates the multisite network. Once done, a Network Admin menu appears in the Dashboard, letting you create and manage multiple sites. Each site shares plugins and themes but keeps its own posts and pages separate. This setup allows managing many sites from one WordPress installation.
