Cakephp中的setlocale

Question

我在cakephp2.9中有一个多语言的web应用程序，可以很好地处理它的.po文件，但现在我还需要翻译日期和时间字符串，我知道这是由setlocale函数完成的。如果我将setlocale内联包含在视图文件中，那么当我将它放入我的语言更改函数(我一直使用它来切换语言)中时，它就不起作用了。

我的语言控制器如下所示：

<?php
App::uses('AppController', 'Controller');

class IdiomasController extends AppController {

    var $uses = array();


    public function idioma_spa($u=null) 
    {

        $this->Session->write('Config.language', 'spa');
        setlocale(LC_TIME, array('es_ES.UTF-8', 'esp'));   


        $this->redirect($this->referer());
    }

    public function idioma_eng($u=null) 
    {
        $this->Session->write('Config.language', 'eng');
        setlocale(LC_TIME, array('en_US.UTF-8', 'eng'));   
        $this->redirect($this->referer());
    }

    public function idioma_ita($u=null) 
    {
        $this->Session->write('Config.language', 'ita');
        setlocale(LC_TIME, array('it_IT.UTF-8', 'ita'));

        $this->redirect($this->referer());
    }
}

这些函数在导航栏的下拉列表中以如下方式调用：

            <?php if($this->Session->read('Config.language')=='spa'):?>
                <li class="nav-item dropdown navbar-right">
                    <a class="nav-link dropdown-toggle" href="" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">ES</a>
                    <div class="dropdown-menu">
                        <a class="dropdown-item" href="<?php echo $this->Html->url( array('plugin' => null,'controller'=>'idiomas','action'=>'idioma_eng',$url3)); ?>">EN</a>
                        <a class="dropdown-item" href="<?php echo $this->Html->url( array('plugin' => null,'controller'=>'idiomas','action'=>'idioma_ita',$url3)); ?>">IT</a>
                    </div>
                </li>
            <?php elseif($this->Session->read('Config.language')=='eng'):?>
                <li class="nav-item dropdown navbar-right">
                    <a class="nav-link dropdown-toggle" href="" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">EN</a>
                    <div class="dropdown-menu">
                        <a class="dropdown-item" href="<?php echo $this->Html->url( array('plugin' => null,'controller'=>'idiomas','action'=>'idioma_spa',$url3)); ?>">ES</a>
                        <a class="dropdown-item" href="<?php echo $this->Html->url( array('plugin' => null,'controller'=>'idiomas','action'=>'idioma_ita',$url3)); ?>">IT</a>
                    </div>
                </li>
            <?php elseif($this->Session->read('Config.language')=='ita'):?>
                <li class="nav-item dropdown navbar-right">
                    <a class="nav-link dropdown-toggle" href="" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">IT</a>
                    <div class="dropdown-menu">
                        <a class="dropdown-item" href="<?php echo $this->Html->url( array('plugin' => null,'controller'=>'idiomas','action'=>'idioma_eng',$url3)); ?>">EN</a>
                        <a class="dropdown-item" href="<?php echo $this->Html->url( array('plugin' => null,'controller'=>'idiomas','action'=>'idioma_spa',$url3)); ?>">ES</a>
                    </div>
                </li>
            <?php endif;?>

很好地解决了这个问题：

类会话扩展控制器{ public $components = AppController (‘$components’)；

    public function beforeFilter() {
        if ($this->Session->check('Config.language')) {
        Configure::write('Config.language', $this->Session->read('Config.language'));
        if ($this->Session->read('Config.language')=='spa')
            setlocale(LC_TIME, array('es_ES.UTF-8', 'esp'));
        else if ($this->Session->read('Config.language')=='ita')
            setlocale(LC_TIME, array('it_IT.UTF-8', 'ita'));
        else
            setlocale(LC_TIME, array('en_US.UTF-8', 'eng'));
        }
    }

}

我的语言控制器简单地保持如下所示：

<?php
App::uses('AppController', 'Controller');

class IdiomasController extends AppController {

    var $uses = array();

    public function idioma_spa($u=null) 
    {
        $this->Session->write('Config.language', 'spa');
        $this->redirect($this->referer());
    }

    public function idioma_eng($u=null) 
    {
        $this->Session->write('Config.language', 'eng');
        $this->redirect($this->referer());
    }

    public function idioma_ita($u=null) 
    {
        $this->Session->write('Config.language', 'ita');
        $this->redirect($this->referer());
    }
}

不知道这是不是最有效的方法，但效果很好！
