Smarty fetch无效

Question

我遇到了smarty问题＆＃34; fetch＆＃34;。它没有加载内容。我检查了找到的地方

$subject = $smarty->fetch("emailtpl:emailsubject");
    $message = $smarty->fetch("emailtpl:emailmessage");

当我尝试打印$ subject和$ message变量时，它们是空白的。我想了解这个问题。请帮忙。代码是： -

#$subject :- This variable has value like "forgot password"
    #$message :- This variable has value like email content

    include_once(ROOTDIR . "/includes/smarty/Smarty.class.php");
        $smarty = new Smarty();
        $smarty->caching = 0;
        $smarty->compile_dir = ROOTDIR . "/" . $templatecompilerpath;
        $smarty->compile_id = md5($subject . $message);
        $smarty->register_resource("emailtpl", array( "emailtpl_template", "emailtpl_timestamp", "emailtpl_secure", "emailtpl_trusted" ));
        $smarty->assign("emailsubject", $subject);
        $smarty->assign("emailmessage", $message);


#It assigns value 
$smarty->assign("enc", $enc);       //enc is vaiable having vluae defined


Then it takes the value as


$subject = $smarty->fetch("emailtpl:emailsubject");
    $message = $smarty->fetch("emailtpl:emailmessage");

但是当我打印$ subject和$ message变量时。他们是空白的。我不明白，这段代码是如何工作的以及emailtpl定义的地方。

如何调试它。请帮忙

Answer 1

这不起作用。 Fetch用于将输出保存在变量中。

获取需要一个模板文件。此模板文件将填充您的分配，并在获取保存在$ subject中后。

顺便说一下。你想用这段代码做什么？！
