wp-admin-settings-api

What problem does it solve?

This Skill prevents insecure and buggy WordPress plugin settings pages by replacing custom form handlers with the built-in Settings API workflow that handles nonces, capability checks, sanitization dispatch, and option storage correctly.

Core Features & Use Cases

• Registers settings correctly: Uses register_setting() on admin_init with an option group and option name so options.php can validate and save reliably.
• Builds full settings screens: Creates sections and fields with add_settings_section(), add_settings_field(), then renders them with do_settings_sections().
• Enforces safe saving and validation: Implements sanitize_callback patterns (including single-option-array storage for tabs) and uses settings_fields() and the required form action options.php.
• Uses REST-aware configuration when needed: Sets show_in_rest schemas appropriately for settings exposed to REST while keeping sanitization consistent.

Quick Start

Use the wp-admin-settings-api skill to implement your plugin’s admin settings page by registering your option on admin_init, rendering the form with settings_fields($option_group) and do_settings_sections($page), and POSTing to options.php with a single sanitize_callback that preserves existing values across tabs.
