add_action( 'customize_register', 'theme_customize_register' );

 * Register individual settings through customizer's API.
 * @param WP_Customize_Manager $wp_customize Customizer reference.
function theme_customize_register( $wp_customize ) {

    // You can first start by adding a section
            'title'       => __( 'Title of your section', 'domain' ),
            'capability'  => 'edit_theme_options',
            'description' => __( 'Some description', 'domain' ),
            'priority'    => 160,
            'type'              => 'textarea',
            'sanitize_callback' => 'theme_sanitize_text', // You can sanitize the text afterwards through this function
            'capability'        => 'edit_theme_options',


In the API docs you can find also what other fields you can use and how you can modify them.

In order to access your settings you can use


Make sure to add this to a plugin or child theme.
