The example in this article describes Yii's method of removing 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?

Let’s first analyze the code implementation:

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);
}
Copy after login

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;
}
Copy after login

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

Just don’t display the asterisk

<?php CHtml::$afterRequiredLabel = &#39;&#39;;?>
<?php echo $form->labelEx($model,&#39;email&#39;); ?>
Copy after login
