How to remove asterisks in required fields in yii

The example in this article describes how Yii removes asterisks in required fields. Share it with everyone for your reference, the details are as follows:

How to remove the asterisks in the required fields?

First analyze the code implementation:

public function labelEx($model,$attribute,$htmlOpti
{
  return CHtml::activeLabelEx($model,$attribute,$htmlOptions);
}
public static function activeLabelEx($model,$attribute,$htmlOpti
{
  $realAttribute=$attribute;
  self::resolveName($model,$attribute); // strip off square brackets if any
  $htmlOptions['required']=$model->isAttributeRequired($attribute);
  return self::activeLabel($model,$realAttribute,$htmlOptions);
}

When the attribute is required, it will render additional CSS class tags. Specifically, it calls CModel::isAttributeRequired to determine whether the attribute is required. If so, it will add a CSS class CHtml::requiredCss (public static $requiredCss='required';) to the label, with CHtml::beforeRequiredLabel (public static $beforeRequiredLabel='';) and CHtml::afterRequiredLabel (public static $afterRequiredLabel='*';) to decorate the label.

public function isAttributeRequired($attribute)
{
  foreach($this->getValidators($attribute) as $validator)
  {
    if($validator instanceof CRequiredValidator) return true;
  }
  return false;
}

So if you want to remove the asterisk or change it to something else, you can directly redefine CHtml::requiredCss, CHtml::beforeRequiredLabel, CHtml::afterRequiredLabel in the view

Just don’t show the asterisk

<&#63;php CHtml::$afterRequiredLabel = '';&#63;>
<&#63;php echo $form->labelEx($model,'email'); ?>

I hope this article will help you design PHP programs based on the Yii framework.
