$default_template_handler_func

提供一个回调函数,这个回调函数将在从资源里面无法获取到模板的时候调用。

Note

该设置一般在当模板是文件资源的时候起作用。 当找不到资源自身的时候,该设置不会调用,而是会抛出SmartyException异常。

Example 13.5. $default_template_handler_func


<?php

$smarty = new Smarty();
$smarty->default_template_handler_func = 'my_default_template_handler_func';

/**
 * 默认模板处理函数
 *
 * 当Smarty的文件资源无法载入需要的文件时调用。
 * 
 * @param string   $type     资源类型 (如:"file", "string", "eval", "resource")
 * @param string   $name     资源名称 (如:"foo/bar.tpl")
 * @param string  &$content  模板的内容
 * @param integer &$modified 模板修改时间
 * @param Smarty   $smarty   Smarty实例
 * @return string|boolean   返回文件路径或布尔值,
 * 布尔值true表示$content 和 $modified已经赋值,
 * 布尔值false表示没有默认模板可供载入。
 */
function my_default_template_handler_func($type, $name, &$content, &$modified, Smarty $smarty) {
    if (false) {
        // 返回文件路径
        return "/tmp/some/foobar.tpl";
    } elseif (false) {
        // 直接返回模板内容
        $content = "the template source";
        $modified = time();
        return true;
    } else {
        // 告诉Smarty无法找到模板
        return false;
    }
}

?>
