Hello Team,
I am using the latest version of WordPress(4.7.2). My custom plugin works smoothly up to 4.5.2. when I tried to install the plugin, upon activation, on the widget area section, sidebar section is not displayed.
该插件在以前的Wordpress版本上运行顺畅。但现在它没有显示出来。请帮我找一个解决方案。
过去几天我坚持这个。如果你们帮助我找到最佳解决方案，将会很有帮助。 [请参阅管理区域窗口小部件显示] [1]

答案 0 :(得分：0)
注意：自版本4.3.0起，Daily_Quotes中WP_Widget的被调用构造函数方法已弃用！请改用
__construct()。在 D：\ xampp \ htdocs \ demowp \ wp-includes \ functions.php 3891
声明一个函数然后调用父构造函数解决了这个问题。
class Daily_Quotes extends WP_Widget {
function __construct(){
parent::__construct(...) // calls constructor from WP_Widget class
}
}
