MainWP Code Snippets Extension

MainWP Code Snippets extension is a utility within the MainWP Pro ecosystem that allows you to create, store, and execute custom PHP code snippets across multiple WordPress child sites—all from a single interface within the MainWP Dashboard.

Instead of having to log in to each individual site to edit theme `functions.php` files or `wp-config.php` files, you can efficiently apply code, transfer data, or modify system configurations across your network with just a few clicks.

3 Code Execution Modes (Snippet Types):

• Execute on Site: Saves the code snippet to the child site’s database via the MainWP Child plugin. The code runs automatically whenever a page loads—much like adding code to a `functions.php` file—but it remains intact even when you change or update your theme.
• Return Info: Executes the code once to retrieve data from your child sites (e.g., counting published posts or checking the PHP version) and displays the results directly within the MainWP Dashboard. This type of snippet is not saved on the child site.
• Add to `wp-config.php`: Injects constants or configuration settings directly into the `wp-config.php` file of your child sites. This mode is highly useful for tasks such as increasing the memory limit (`WP_MEMORY_LIMIT`), disabling WP-Cron, enabling debug mode, or blocking outgoing requests.
