{insert} tags in the template.
插入插件用来执行在模板中被 {insert} 标记调用的函数 。

string smarty_insert_ name (array $params, object &$smarty)

The first parameter to the function is an associative array of attributes passed to the insert. Either Access those values directly, e.g. $params['start'] or use extract($params) to import them into the symbol table.
函数的第一个参数是一个传递给插入动作的属性集合数组。每一种方式都可以直接获取那些属性值，例如$params['start']，或用extract($params)将属性导入符号表中。

The insert function is supposed to return the result which will be substituted in place of the {insert} tag in the template.
插入函数将会返回某值，该值将在模板中的 {insert} 标记处被替换。
