在我的模板中创建一个函数的非常简单的例子中遇到了麻烦。我希望最后能用它来为菜单获取数据。
我对这个例子做了一些改动，但这只是为了让它工作。我在plugins目录中创建了一个function.load_ticker.php文件（甚至使用了getPluginsDir（）来确保路径正确）

function smarty_function_load_ticker($params, $smarty)
{
  // assign template variable
  $smarty->assign('test', '123');
}

在shortcenter.tpl文件中，我有

{load_ticker} {$test}

然后我得到很多以下的。。
数组（[0]=〉/var/www/html/my_app/vendor/smarty/smarty/libs/plugins/）#0__my_app_autoload（Smarty_Internal_Compile_Load_Ticker）#1 spl_autoload_call（Smarty_Internal_Compile_Load_Ticker）#2 class_exists（Smarty_Internal_Compile_Load_Ticker）在[/var/www/html/my_app/vendor/smarty/smarty/libs/sysplugins/smarty_internal_templatecompilerbase. php：[/var/www/html/my_app/vendor/smarty/smarty/libs/sysplugins/smarty_internal_templatecompilerbase]. php：[/var/www/html/my_app/vendor/smarty/smarty/libs/sysplugins/smarty_internal_templatecompilerbase. html/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/sphp：[/var/www/html/my_app/vendor/smarty/smarty/libs/sysplugins/smarty_internal_templatecompilerbase. html/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/software/sphp：[/var/www/html/my_app/vendor/smarty/smarty/libs/sysplugins/smarty_internal_templateparser. html] [/var/www/html/my_app/vendor/smarty/smarty/libs/sysplugins/smarty_internal_templateparser. html] php：[/var/www/html/my_app/vendor/smarty/smarty/libs/sysplugins/smarty_internal_templateparser. php：[/var/www/html/my_app/vendor/smarty/smarty/libs/sysplugins/smarty_internal_templateparser]#8 Smarty_Internal_Templateparser-〉yy_reduce（12）在[/var/www/html/my_app/vendor/smarty/smarty/libs/sysplugins/smarty_internal_templateparser. php：[/var/www/html/my_app/vendor/smarty/smarty/libs/sysplugins/smarty_internal_smartytemplatecompiler. php：#10 Smarty_Internal_SmartyTemplateCompiler-〉doCompile（{include file =" sidebar. tpl "} {load_tickker} {$test}
我的smarty版本是4.3.0，我的php版本是7.2（我知道这是旧的，也许这就是问题所在？））
有什么建议吗？
谢谢
