Warning: Use of undefined constant taotag – assumed ‘taotag’ (this will throw an Error in a future version of PHP) 解决办法

今天我的一位网友在用wordpress主题“知更鸟”的时候，当他的PHP升级到7.2的时候，打开网站做出如下提示：

Warning: Use of undefined constant videotag - assumed 'videotag' (this will throw an Error in a future version of PHP) in /www/wwwroot/www.fujieace.com/wp-content/themes/fujieace/inc/post-taxonomy.php on line 271
Warning: Use of undefined constant taotag - assumed 'taotag' (this will throw an Error in a future version of PHP) in /www/wwwroot/www.fujieace.com/wp-content/themes/fujieace/inc/post-taxonomy.php on line 374

如果你是用了“知更鸟”这个主题，甚至还会出现如下类似错误：

constant gallerytag – assumed ‘gallerytag’ (this will throw an Error in a future version of PHP) in
constant videotag – assumed ‘videotag’ (this will throw an Error in a future version of PHP) in
constant taotag – assumed ‘taotag’ (this will throw an Error in a future version of PHP) in
constant filtersa – assumed ‘filtersa’ (this will throw an Error in a future version of PHP) in
constant filtersb – assumed ‘filtersb’ (this will throw an Error in a future version of PHP) in

解决方法

以上这些错误大概意思是“使用了未定义的常量gallerytag、videotag、taotag、filtersa、filtersb，这将在未来的PHP版本中引发错误“；

解决此种问题其实也不是很难，只是报了”Warning警告“，我们只需要关闭”PHP错误提示“就行了。具体步骤如下：

1、打开 php.ini

2、设置 error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT

3、设置 display_errors = Off

4、重启PHP
