Php 如何在codeigniter temaplate中放入变量

我有一个看法：

public function index()
{

    $lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);
    if ($lang == "fr"){
        $this->smarty->display('excel.tpl');    
    }
    else{
        $this->smarty->display('excel_eng.tpl');
    }
}

我的模板：

<div class="fullscreen background" id="landing-page-image">
    {include 'components/menu.tpl'}
</div>

{include'components/menu.tpl'}

我想根据语言更换一个组件

怎么做？

您可以这样做：

excel.tpl:

<div class="fullscreen background" id="landing-page-image">
    {include 'components/menu.tpl'}
</div>

<div class="fullscreen background" id="landing-page-image">
    {include 'components/menu_eng.tpl'}
</div>

...

$lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);

$smarty->assign('lang' , $lang); // passing lang to templates

....

<div class="fullscreen background" id="landing-page-image">
    {include 'components/menu_$lang.tpl'}
</div>

HTML代码：

<div class="fullscreen background" id="landing-page-image">
    {include 'components/menu.tpl'}
</div>

<div class="fullscreen background" id="landing-page-image">
    {include 'components/menu_eng.tpl'}
</div>

...

$lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);

$smarty->assign('lang' , $lang); // passing lang to templates

....

<div class="fullscreen background" id="landing-page-image">
    {include 'components/menu_$lang.tpl'}
</div>

{include'组件/菜单$lang.tpl'}

1.这里的第一个选项是加载语言变量并为它们提供公共模板：

$lang = 'en';//your default language
$available_langs = array('en', 'fr'); //your set of languages
$browser_lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);
if (in_array($browser_lang, $available_langs)) {
   $lang = $browser_lang; //set language according to browser
}
//assumed you keep your language variables in /app/language/lang_en.php
require_once(APPPATH.'language/lang_'.$lang.'.php');
$this->smarty->assign('lang_vars', $lang_vars);

lang_en.php的示例：

<?php
$lang_vars = array(
'some_var_1'=>'Some string',
'some_var_2'=>'Another string',
);

---

但这被认为是不好的做法，因为您需要支持和更改两组模板。

如何将变量放入{include'components/variable here'}？？当您从一开始就使用不同的模板时，为什么要传递变量？
