How to escape this? I'm now using sanitize_text_field(). Was first esc_attr().
<?php
function ajax_save_columns() {
global $wp_registered_sidebars;
header( "Content-Type: application/json" );
if( isset( $_POST['sidebar'], $_POST['amount_columns'] ) && ! empty( $wp_registered_sidebars[ $_POST['sidebar'] ] ) ) {
$options = get_option( 'horizontal_sidebar_columns', array() );
$options[ $_POST['sidebar'] ] = absint( $_POST['amount_columns'] );
update_option( 'horizontal_sidebar_columns', $options );

Give wp_nav_menu() a different class then default. In some cases themes style on the class 'menu'. What result in possible weird behavior.
<?php
class Nav_Menu_Widget_Classname {
public function __construct() {
add_action( 'widget_display_callback', array( $this, 'menu_different_class' ), 10, 2 );
}
public function menu_different_class( $settings, $widget ) {
if( $widget instanceof WP_Nav_Menu_Widget )
add_filter( 'wp_nav_menu_args', array( $this, 'wp_nav_menu_args' ) );
