我遇到了一个奇怪的问题，我制作了一个简单的自定义小部件，用于在小部件中显示联系人信息。

出于某种原因，当我添加电话号码时，它会重复多次，如您在此处所见：

我已经包含了下面小部件的代码。没有什么特别不寻常的地方：

<?php


// Block direct requests
if ( !defined(\'ABSPATH\') )
    die(\'-1\');


add_action( \'widgets_init\', function(){
   register_widget( \'my_custom_contact_widget\' );
}); 

/**
 * Adds my_custom_contact_widget widget.
*/
class my_custom_contact_widget extends WP_Widget {

/**
 * Register widget with WordPress.
 */
function __construct() {
    parent::__construct(
        \'my_custom_contact_widget\', // Base ID
        __(\'Contact Info\', \'my_custom-theme-support\'), // Name
        array( \'description\' => __( \'Your business address and email.\', \'my_custom-theme-support\' ), ) // Args
    );
}

如果有人知道我做错了什么。我很感激你的想法。

非常感谢。
