Inserts 插入

Insert plugins are used to implement functions that are invoked by{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 。

stringsmarty_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.$params['start'] or useextract($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。

/*

function smarty_insert_time($params, &$smarty)
{
if (empty($params['format'])) {
$smarty->trigger_error("insert time: missing 'format' parameter");
return;
}
$datetime = strftime($params['format']);
return $datetime;
}
