Extension Description

MainWP Code Snippets Extension is an simple way to add code snippets to your child sites from one centralized location. No need to edit to your theme’s functions.php file or wp-config anymore!

Code snippet a small chunk of PHP code that can be inserted directly into your child sites. Sometimes they contain full functions, other times they simply modify an existing function.

This tool is for advanced users only. We only recommend utilizing it if you are experienced using PHP.

Create And Execute Your Own PHP Code Snippets Across Your Sites

With this Extension you can execute tasks like synchronizing the settings of a plugin, changing the content of any posts , updating widgets or just get post counts across your network and all of this is handled from your Dashboard.

The MainWP Code Snippet Extension allows you to run code in three ways:

1. Have a Code Snippet execute a function on the Child site.

You would use this option to make actual changes on your child sites. For example, if you wanted to customize the admin footer across different sites in your network you would use this option.

Show full description

2. Have a Code Snippet return information from a Child site.

This option queries the child and returns the information to you. An example would be if you wanted to know the published post count of all of your sites.

3. Have a Code Snippet edit the wp-config.php file on a Child site.
