The nexter/create-snippet ability creates a new code snippet in Nexter Extension. It supports PHP, CSS, JavaScript, and HTML snippet types with configurable insertion locations, execution scopes, scheduling dates, and display conditions. New snippets are created as inactive by default to prevent accidental execution. Use nexter/toggle-snippet with status=1 to activate after creation.

Key Takeaways

New snippets are created as inactive (status=0) by default to prevent accidental execution on creation.

For PHP snippets, do not include the opening tag. Nexter Extension adds it automatically.

Supported types are php, css, javascript, and htmlmixed.

Use start_date and end_date to schedule a snippet to run only within a specific date range.

The ability returns the new snippet ID so you can immediately reference it in toggle, update, or get calls.

Required Setup

The Code Snippets feature must be enabled in Nexter Extension. Use nexter/list-extensions to confirm it is active, or nexter/toggle-extension to enable it. After creating a snippet, use nexter/toggle-snippet with status=1 to activate it.

What It Returns

The ability returns a confirmation object on success.

success (boolean) confirming the snippet was created.

id (string) of the newly created snippet for use in subsequent toggle, update, or get calls.

message confirming creation status.

When to Use This Ability

Add a PHP function, filter, or action to your site without editing theme or plugin files.

Inject CSS or JavaScript on specific pages using display conditions without a separate plugin.

Schedule a promotional script or banner to run only between a start date and end date.

Create a snippet as inactive first, review the code, then activate it with nexter/toggle-snippet when ready.
