display
显示

void display(string template [, string cache_id [, string compile_id]])

This displays the template. 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.

显示模板,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 display().

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 13-12. display
例子 13-12. 显示

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);

}

// display the output
// 显示输出
$smarty->display("index.tpl");

Use the syntax for template resources to display files outside of the $template_dir directory.

通过模板资源的语法来使用不在$template_dir模板目录 下的文件。

Example 13-13. function display template resource examples
例子 13-13. 显示模板资源

// absolute filepath
// 绝对路径
$smarty->display("/usr/local/include/templates/header.tpl");

// absolute filepath (same thing)
// 绝对路径(另外一种方式)
$smarty->display("file:/usr/local/include/templates/header.tpl");

// windows absolute filepath (MUST use "file:" prefix)
// WINDOS平台下的绝对路径(必须使用“file:”前缀)
$smarty->display("file:C:/www/pub/templates/header.tpl");

// include from template resource named "db"
// 从模板资源“db“中调用
$smarty->display("db:header.tpl");
