yii2.0 - Yii::t()的使用 -- 语言包的使用

第一种情况：在控制器和试图中：

第一步：在protected/config文件夹下的main.php中做如下设置：??

 return [
    'vendorPath' => dirname(dirname(__DIR__)) . '/vendor',
    'language' => 'zh-CN',
    'components' => [
        'cache' => [
            'class' => 'yii\caching\FileCache',
        ],
        'i18n' => [
            'translations' => [

                    //'basePath' => '@app/messages',

        ],*/
        
        'user' => [

            // 'enableAutoLogin' => true,
            'authTimeout'     =>'6000',



        ],

        'errorHandler' => [
            'errorAction' => 'site/error',
        ],
        'authManager' => [

            ],
        ],
//================其他配置  结束 ========================
    ],
 ]

 

第二步：定义翻译文件

在根目录的【messages-》zh-CN】文件夹下，创建app.php文件

return array(
    'My Web Application'=>'我的web站点',
    'Home'=>'首页',
    'About'=>'关于',
    'Contact'=>'联系我们',
    'Login'=>'登录',
    'Logout'=>'退出',
 );

 

第三步：使用翻译：在控制器和视图中都可使用

//通过内置的Yii::t()方法调用即可 
Yii::t('app','Home'); //返回：【首页】文字

 

 

第二种情况：在mode中??不是很懂

public function attributeLabels()
 {
        return [
            'id' => 'ID',
            'pur_number' => Yii::t('app', '采购单号'),  //第一种
            'purchase_warehouse' => '仓库',  //第二种
        ];
 }

在视图使用：

<?= $form->field($model, 'pur_number') ?>
<?= $form->field($model, 'purchase_warehouse') ?>

显示：采购单号、仓库
