制止浏览器查看WordPress主题源代码

为了保护原创Wordpress主题或是原创文章内容被恶意复制传播,我们可能会想到从功能上禁用复制的方法,这里大挖给大家推荐下如何通过js来达到禁用浏览器查看源代码的功能,希望对大家有所帮助。 [crayon-615a084581c16784010542/] 同时分享给大家一段可以网页禁止右键、禁止查看源代码、禁止复制的代码的功能,只需要把下面代码复制到header.php文件内即可生效。 [cra

解决方案

找到wp-admin/includes/file.php文件,删除492-599行的如下代码:
这个调整方式仅仅是一个暂且替换方式,由于若是wordpress程序更新焦点的wp-admin内的文件都市被替换掉。
