Introduction to WP_Customize_Nav_Menus::print_post_type_container()
If you are a WordPress developer, you are probably familiar with the WordPress Customizer section. One of the key classes in this section is WP_Customize_Nav_Menus, which provides functionalities for managing and customizing various menu types. One of the crucial methods in this class is print_post_type_container(), which plays a role in displaying sections related to post type management in customization.
Essentially, this method helps with certain required capabilities for displaying and managing post types in the WordPress Customizer. This means that you can easily manage post types, including regular posts, pages, and even custom post types, by adding them to your own menus.
By using this method, the user can easily manage content types appropriately and display that content in their customized menu.
Some key features of print_post_type_container() include retrieving necessary information for each post type and managing interactions between each type of post and the corresponding menu. This interaction allows you to display specific features of posts visually and attractively in the menu. In other words, this method allows users to easily perform their own selections and create suitable menus for their websites.
Now let's take a look at a simple example of how to use this method. Below, you will find an example of using print_post_type_container() to display different types of posts in a menu.
function my_customize_register( $wp_customize ) {
$wp_customize->add_section('nav_menu_section', array(
'title' => __('Custom Nav Menu', 'textdomain'),
'priority' => 30,
));
$wp_customize->add_setting('my_menu_setting', array(
'default' => 'default',
));
$wp_customize->add_control( new WP_Customize_Control( $wp_customize, 'my_menu_control', array(
'label' => __('Choose a Menu', 'textdomain'),
'section' => 'nav_menu_section',
'settings' => 'my_menu_setting',
'type' => 'select',
'choices' => array(
'menu1' => __('Menu 1', 'textdomain'),
'menu2' => __('Menu 2', 'textdomain'),
),
)));
// You need to add a container and call print_post_type_container
$nav_menu_container = new WP_Customize_Nav_Menus();
$nav_menu_container->print_post_type_container();
}
add_action( 'customize_register', 'my_customize_register' );
