篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了解决joomla把标签最短文本长度限定为3的问题相关的知识，希望对你有一定的参考价值。
对于中文环境来说，把标签文本最小长度限制为3是不合理的。因为中文是双音节词语，比拉丁文等西方国家语言简短，大量的有实际意义的词汇的文本长度为2。然而Joomla不支持配置它。经过调试，我发现它的代码把标签最小长度写在代码中限定死了。代码位于libraries\\cms\\html文件夹下tag.php文件里，第168行：

此外在administrator\\components\\com_tags文件夹下config.xml文件中发现配置节第181行也有长度的文字描述：
