无法让wpColorPicker在小部件中工作

我可以显示颜色选择器，我可以更改颜色并看到保存按钮，但是没有任何内容保存到DB，我得到

未定义索引：my\\u color”，文件：“wp content/plugins/my\\u plugin/my\\u color。php”，第53行

这是我的小部件：

<?php

    function __construct() {
        add_action(\'admin_print_styles-widgets.php\', array( $this, \'load_color_picker_style\' ) );
        $args = array(
            \'name\' => esc_html__( \'widget007\', \'txt-domaine\' ),
            \'description\' => esc_html__( \'Something\', \'txt-domaine\' )
        );
        parent::__construct( \'my_widget007\', \'\', $args );
    }

    function load_color_picker_style() {

    function form( $instance ) {

                        }, 3000 )
                    });
                }

My widgets do not save

每次我保存我的小部件并离开页面时，我的小部件都会消失。侧边栏已完全清空，不会保存任何更改。控制台或PHP日志中没有任何错误。如果我将小部件直接复制并保存在数据库中widgets_text, 它们将被显示，但我仍然无法在侧边栏中添加或删除任何内容。这只发生在我的右侧边栏上，左侧边栏工作正常，但它们都以相同的方式注册。这是我注册侧边栏的方式：function my_widgets_init() { register_sidebar( array ( \'name\'
