Updated On : May 29, 2026By : Reading Time : 2 minutes

Key Takeaways

  • Update a code snippet in WordPress using the nexter/update-snippet ability by providing the required id parameter.
  • Retrieve the current state of a snippet with nexter/get-snippet before making updates to ensure accuracy.
  • Use nexter/toggle-snippet to change only the active state of a snippet without altering other fields.
Table of Contents

The nexter/update-snippet ability updates an existing Nexter Extension code snippet by its ID. Pass the snippet ID and any fields you want to change. Only the fields you provide are saved. All other fields remain at their current values. Use nexter/get-snippet to read the current state before updating.

Key Takeaways

The id parameter is required. All other parameters are optional.

Only the fields you pass are updated. Omitted fields keep their existing values.

Use nexter/list-snippets to find the snippet ID before calling this ability.

To change only the active state, use nexter/toggle-snippet instead.
