Smarty成員方法:registerPlugin()

2018-12-02 16:34 更新

Name

registerPlugin() — 注冊插件

說明

void registerPlugin(string type,
                    string name,
                    mixed callback,
                    bool cacheable,
                    mixed cache_attrs);

該函數(shù)將以插件的形式來注冊函數(shù)或者方法。參數(shù)如下：

type defines the type of the plugin. Valid values are "function", "block", "compiler" and "modifier".
name defines the name of the plugin.
callback defines the PHP callback. it can be either:
- A string containing the function name
- An array of the form array(&$object, $method) with &$object being a reference to an object and $method being a string containing the method-name
- An array of the form array($class, $method) with $class being the class name and $method being a method of the class.
大多數(shù)情況下cacheable 和 cache_attrs可被省略。參見緩存能力設置它們的值。

Example 14.39. 注冊函數(shù)

<?php
$smarty->registerPlugin("function","date_now", "print_current_date");

function print_current_date($params, $smarty)
{
  if(empty($params["format"])) {
    $format = "%b %e, %Y";
  } else {
    $format = $params["format"];
  }
  return strftime($format,time());
}
?>

在模板中：

{date_now}

{* 或定義時間格式 *}
{date_now format="%Y/%m/%d"}

Example 14.40. 注冊塊函數(shù)

<?php
// 函數(shù)定義
function do_translation ($params, $content, $smarty, &$repeat, $template)
{
  if (isset($content)) {
    $lang = $params["lang"];
    // 這里可以放置翻譯 $content 的代碼
    return $translation;
  }
}

// 注冊到Smarty
$smarty->registerPlugin("block","translate", "do_translation");
?>

模板中：

{translate lang="br"}Hello, world!{/translate}

Example 14.41. 注冊修飾器

<?php

// 我們將PHP的stripslashes函數(shù)映射成一個Smarty的修飾器
$smarty->registerPlugin("modifier","ss", "stripslashes");

?>

模板中可使用ss來過濾反斜線。

<?php
{$var|ss}
?>

參見 unregisterPlugin(), 插件函數(shù), 塊函數(shù), 編譯函數(shù), 和修飾器。
