Some examples: function.html_select_date.php, resource.db.php, modifier.spacify.php *name*为合法标识符，仅包含字母、数字和下划线的，查看[php变量](http://php.net/language.variables)。 举例如下：function.html_select_date.php, resource.db.php, modifier.spacify.php。 > The plugin functions inside the plugin files must be named as follows: 插件内的函数应遵循如下命名约定： smarty_type, _name () The meanings of type and name are the same as above. An example modifier name foo would be function smarty_modifier_foo(). ***type***和*name*的含义同上。 举例，调节器（modifier）命名为foo，那么按规则函数为smarty_modifier_foo()。 Smarty will output appropriate error messages if the plugin file it needs is not found, or if the file or the plugin function are named improperly. 如果指定的插件文件不存在或文件、函数命名不合规范，Smarty会输出对应的错误信息。 <table summary="Footer navigation table" width="100%" border="0" cellpadding="0" cellspacing="0"><tr><td width="33%" align="left" valign="top"><a href="plugins.how.plugins.work.html" accesskey="P">Prev</a></td><td width="34%" align="center" valign="top"><a href="index.html" accesskey="H">Home</a></td><td width="33%" align="right" valign="top"><a href="plugins.writing.html" accesskey="N">Next</a></td></tr><tr><td width="33%" align="left" valign="top">How Plugins Work<br/> 插件如何工作</td><td width="34%" align="center" valign="top"><a href="plugins.html" accesskey="U">Up</a></td><td width="33%" align="right" valign="top">Writing Plugins 编写插件</td></tr></table>
