Overview

Managing PHP snippets across a group of WordPress sites can mean repeating the same edits on each site. MainWP Code Snippets Extension brings that work into the MainWP Dashboard, where you can add, edit, and store snippets for use across child sites. It suits developers, agencies, and site managers who oversee multiple WordPress installations and want a central place to handle routine code tasks.

Run snippets on child sites, use them to retrieve information such as post counts, or make changes to wp-config.php remotely. Snippets can also handle tasks such as cleaning up trash, changing settings, creating redirections, and updating widgets or plugin configurations. The extension supports code-based site hardening, including disabling theme and plugin editors and blocking core updates. Its documentation recommends testing code on test sites before using it on live sites.

Features

  • Central snippet management: Add, edit, and store PHP code snippets for your child sites from the MainWP Dashboard instead of switching between individual WordPress sites.
  • Run code across sites: Execute snippets on multiple child sites, including across all managed sites, to apply the same code-based task throughout your portfolio.
  • Retrieve site information: Use snippets to retrieve site data, including post counts, from child sites through the centralized dashboard.
  • Change configuration files: Modify wp-config.php files remotely through snippets, without logging into each child site separately.
  • Apply hardening settings: Use code snippets to disable theme and plugin editors, block core updates, adjust auto-save intervals, or prevent external HTTP requests.
  • Update settings and widgets: Synchronize plugin configurations and update widgets across managed WordPress sites using snippets from the MainWP Dashboard.

Best for

  • WordPress agencies managing child sites
  • Developers maintaining multiple WordPress sites
  • Site managers handling routine code tasks
