Smarty：如何读取存储在数据库中的{$ var}？ [英] Smarty: How to read a {$var} stored in the database?

问题描述

我将codeigniter与smarty一起使用。

I use codeigniter with smarty.

我在数据库中存储了一个名为 $ serverName 的变量。我想将其扩展为实际值 Pedrosite 。但是在加载页面时，它显示的恰好是 {$ serverName} 而不是值。

I have a variable stored in the db called $serverName. I want to expand it to its actual value "Pedrosite". But when the page is loaded, it displays exactly {$serverName} and not the value.

所以我发现使用smarty的fetch函数在stackoverflow上使用以下解决方案：

So I found this solution on stackoverflow, using smarty's fetch function:

$ data ['content'] 包含来自

$data['content'] = $this->CI->smarty->fetch('string:'.$data['content']);

这样，我可以显示聪明的变量，例如： {$ smarty .const.FCPATH}

With that, I can display the smarty vars, like: {$smarty.const.FCPATH}

但是我的自定义 $ vars 都没有，会显示在常规模板（ .tpl ）中。

But none of my custom $vars while they can be shown in a regular template (.tpl).

所以我发现这种变通方法对我来说似乎很棘手：

So I found this workaround that looks very hacky to me:

$this->CI->smarty->assign('serverName', $this->CI->config->item('server_name'));

我可以将其放入我的 __ construct 功能，那么它将影响整个站点，然后正确加载。但我不确定这是否是正确的方法。

I can put this in one of my __construct function and then it will affect the whole site, and then it loads properly. But I'm not sure it's the right way to proceed at all.

推荐答案

我不太了解您的问题，但是，如果您有变量 $ serverName 并且内容包含 Pedrosite ，则可以这样显示：

I don't really understand your question, but, if you have your variable $serverName and it content "Pedrosite" you can display it like that :

$this->smarty->assign('serverName' , $serverName);
$this->smarty->view('/modules/xxxxxx');

并将其显示在您的.html文件中，例如：

And display it in your .html file for example :

<p>{$serverName}</p>
