yii 去掉必填项的星号
先分析下代码实现:
public function labelEx($model,$attribute,$htmlOptions=array())
{
return CHtml::activeLabelEx($model,$attribute,$htmlOptions);
}
public static function activeLabelEx($model,$attribute,$htmlOptions=array())
{
$realAttribute=$attribute;
self::resolveName($model,$attribute); // strip off square brackets if any
$htmlOptions['required']=$model->isAttributeRequired($attribute);
return self::activeLabel($model,$realAttribute,$htmlOptions);
}
当属性是必填的时候,它将渲染额外的CSS类个标记。特别的,它调用CModel::isAttributeRequired来决定属性是否为必填的。如果是,它将添加一个CSS类CHtml::requiredCss (public static $requiredCss='required';)到标签上,用CHtml::beforeRequiredLabel(public static $beforeRequiredLabel='';)和CHtml::afterRequiredLabel (public static $afterRequiredLabel='*';)来装饰标签。
public function isAttributeRequired($attribute)www.2cto.com
{
foreach($this->getValidators($attribute) as $validator)
{
if($validator instanceof CRequiredValidator) return true;
}
return false;
}
所以要去掉星号 或者换成别的可以再view中直接重新定义CHtml::requiredCss、CHtml::beforeRequiredLabel、CHtml::afterRequiredLabel即可
不显示星号就可这样
labelEx($model,'email'); ?>
