Cakephp中的setlocale

Question

我在cakephp 2.9中有一个多语言的web应用程序与它的.po文件很好地工作但是现在我还需要转换日期和时间字符串，我知道这些字符串由setlocale函数完成。如果我在视图文件中包含setlocale inline但是当我把它放在我的语言更改函数中时（我一直用它来切换语言）它不起作用。

我的语言控制器如下：

<?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这种方式调用：

            <?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：

class AppController扩展Controller {public $ components = array（'Session'）;

    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'));
        }
    }

}

我的语言控制器就像：

<?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());
    }
}

不知道它是否是最有效的方式，但却像魅力一样！
