Question

奇怪的问题，但在这里。我想为一个模型设置多个标签数组，然后在它们之间切换。我需要的是：

public function attributeLabels_1(){
     array(
          'line_1'=>'Authentication Number'
     )
}
public function attributeLabels_2(){
     array(
          'line_1'=>'Receipt Number'
     )
}

这可能吗？如果可以的话，你怎么改变使用哪个数组？

非常感谢。

我不记得attributeLabels()返回的列表是否缓存在某处，如果不是，那么这应该有效：

/** implementation */

private $_currentLabelCollection = null;

public function getCurrentLabelCollection() {
    return $this->_currentLabelCollection;
}

public function setCurrentLabelCollection($value) {
    if(!$value || array_key_exists($value, $this->_attributeLabelCollections)) {
        $this->_currentLabelCollection = $value;
    } else {
        throw new CException(Yii::t("error", "Model {model} does not have a label collection named {key}.", array(
            '{model}' => get_class($this),
            '{key}' => $value,
        )));
    }
}

private $_attributeLabelCollections = array(
    'collection1' => array(
        'line_1' => 'Authentication Number',
    ),
    'collection2' => array(
        'line_1' => 'Receipt Number',
    ),
);

public function attributeLabels() {
    if($this->_currentLabelCollection) {
        return $this->_attributeLabelCollections[$this->_currentLabelCollection];
    } else {
        return reset($this->_attributeLabelCollections);
    }
}

/** usage */

// use labels from 'collection2'
$model->currentLabelCollection = 'collection2';

// use labels from the first defined collection
$model->currentLabelCollection = null;
