add_settings_section( string $id, string $title, callable $callback, string $page )

Add a new section to a settings page.

Description

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.

Parameters

$id

(string) (Required) Slug-name to identify the section. Used in the 'id' attribute of tags.

$title

(string) (Required) Formatted title of the section. Shown as the heading for the section.

$callback

(callable) (Required) Function that echos out any content at the top of the section (between heading and fields).

$page

(string) (Required) The slug-name of the settings page on which to show the section. Built-in pages include 'general', 'reading', 'writing', 'discussion', 'media', etc. Create your own using add_options_page();

More Information

The callback function receives a single optional argument, which is an array with three elements. Example:

add_settings_section(
	'eg_setting_section',
	'Example settings section in reading',
	'eg_setting_section_callback_function',
	'reading'
);
function eg_setting_section_callback_function( $arg ) {
	// echo section intro text here
	echo '<p>id: ' . $arg['id'] . '</p>';             // id: eg_setting_section
	echo '<p>title: ' . $arg['title'] . '</p>';       // title: Example settings section in reading
	echo '<p>callback: ' . $arg['callback'] . '</p>'; // callback: eg_setting_section_callback_function
}
