Question

我正在开发一个Wordpress插件，并通过Wordpress＆＃39;进行更新。 SVN。当进入回调函数getLogoUrl的函数时，我收到此错误：

致命错误：Class＆＃39;插件＆＃39;找不到 /customers/1/6/2/carpe-noctem.no/httpd.www/wp-content/plugins/logo-switcher/inc/helpers.php 在第21行

问题是该类根本不存在，并且文件很久就被删除了。该文件中的代码已移至另一个文件，但错误显示已从系统中删除的文件。

这是具有应该回调的类的文件。

}

$Logo_Switcher_Plugin = new class_Logo_Switcher;

获得任何帮助？

Answer 1

不要使用class_exists（）

if (!class_exists('class_Logo_Switcher')) {

class class_Logo_Switcher { }

}
