add_settings_section() │ WP 2.7.0

Add a new section to a settings page.

Part of the Settings API. Use this to define new settings sections for an admin page. Show settings sections in your admin page callback function with do_settings_sections(). Add settings fields to your section with add_settings_field().

The $callback argument should be the name of a function that echoes out any content you want to show at the top of the settings section before the actual fields. It can output nothing if you want.

No Hooks.

Return
