fetch
取得输出的内容

string fetch (string template [, string cache_id [, string compile_id]])

This returns the template output instead of displaying it. Supply a valid template resource type and path. As an optional second parameter, you can pass a cache id. See the caching section for more information.

返回一个模板输出的内容(HTML代码),而不是直接显示出来,需要指定一个合法的模 板资源的类型和路径。你还可以通过 第二个可选参数指定一个缓存号,相关的信息可以查看缓存。

As an optional third parameter, you can pass a compile id. This is in the event that you want to compile different versions of the same template, such as having separate templates compiled for different languages. Another use for compile_id is when you use more than one $template_dir but only one $compile_dir. Set a separate compile_id for each $template_dir, otherwise templates of the same name will overwrite each other. You can also set the $compile_id variable once instead of passing this to each call to fetch().

通过第三个可选参数,可以指定一个编译号。这在你想把一个模板编译成不同版本时使用,比如针对不同的语言编译模板。编译号的另外一个作用是,如果你 有多个$template_dir模板目录,但只有一个$compile_dir编译后存档目录,这时可以为每一个$template_dir模板目录指 定一个编译号,以避免相同的模板文件在编译后会互相覆盖。相对于在每一次调用display()的时候都指定编译号,也可以通过设置$compile_id编 译号属性来一次性设定。

Example 13-14. fetch
例子 13-14. 取得输出的内容

include("Smarty.class.php");
$smarty = new Smarty;

$smarty->caching = true;

// only do db calls if cache doesn't exist
// 只有在缓存不存在时才调用数据库
if(!$smarty->is_cached("index.tpl"))
{

// dummy up some data
$address = "245 N 50th";
$db_data = array(
"City" => "Lincoln",
"State" => "Nebraska",
"Zip" = > "68502"
);

$smarty->assign("Name","Fred");
$smarty->assign("Address",$address);
$smarty->assign($db_data);

}

// capture the output
// 捕获输出
$output = $smarty->fetch("index.tpl");

// do something with $output here
// 对将要输出的内容进行处理

echo $output;
