They can also be unregistered by using unregister_* API functions. For the plugins that are registered at runtime, the name of the plugin function(s) does not have to follow the naming convention. If a plugin depends on some functionality provided by another plugin (as is the case with some plugins bundled with Smarty), then the proper way to load the needed plugin is this: Smarty既可自動從文件系統加載插件，也可在運行時通過register_* API函數注冊插件。當然，也可以通過unregister_* API函數卸載已經載入的插件。對于只在運行時注冊的插件函數不必遵守命名約定。如果某個插件依賴其它插件的某些功能（事實上，一些插件被綁定在Smarty中），那么可以通過如下方法加載需要的插件： | ~~~ <?phprequire_once $smarty->_get_plugin_filepath('function', 'html_options');?> ~~~ | |-----| As a general rule, Smarty object is always passed to the plugins as the last parameter with two exceptions: modifiers do not get passed the Smarty object at all. blocks get passed $repeat after the Smarty object to keep backwards compatibility to older versions of Smarty. 按照慣例，Smarty對象通常作為最后一個參數傳遞給插件，但有兩個例外：調節器不須接受Smarty對象的傳遞。為了向前兼容舊版Smarty，[塊插件](#)將$repeat排在Smarty對象后面作為最后一個參數（$smarty作為倒數第二個參數）。 <table summary="Footer navigation table" width="100%" border="0" cellpadding="0" cellspacing="0"><tr><td width="33%" align="left" valign="top"><a href="plugins.naming.conventions.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.functions.html" accesskey="N">Next</a></td></tr><tr><td width="33%" align="left" valign="top">Naming Conventions <br/> 命名約定</td><td width="34%" align="center" valign="top"><a href="plugins.html" accesskey="U">Up</a></td><td width="33%" align="right" valign="top">Template Functions 模板函數</td></tr></table>
