wordpress函数add_settings_section()用法示例

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

Add a new section to a settings page.

描述

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.

参数

$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();

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

   
   
   add_settings_section(
   	'eg_setting_section',
   	__( 'Example settings section in reading', 'textdomain' ),
   	'wpdocs_setting_section_callback_function',
   	'reading'
   );
   
   /**
    * Settings section display callback.
    *
    * @param array $args Display arguments.
    */ 
   function wpdocs_setting_section_callback_function( $args ) {
   	// echo section intro text here
   	echo '<p>id: ' . esc_html( $args['id'] ) . '</p>';                         // id: eg_setting_section
   	echo '<p>title: ' . apply_filters( 'the_title', $args['title'] ) . '</p>'; // title: Example settings section in reading
   	echo '<p>callback: ' . esc_html( $args['callback'] ) . '</p>';             // callback: eg_setting_section_callback_function
   }
