This example describes how Yii removes asterisks from required fields. Share to everyone for your reference, as follows:

How do I get rid of the asterisk in the required fields?

First analyze the following 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);}

When a property is required, it renders additional CSS class tags. In particular, it calls cmodel::isattributerequired to determine if a property is required. If it is, it adds 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 you have to remove the asterisk or replace it with another view directly redefine Chtml::requiredcss, Chtml::beforerequiredlabel, Chtml::afterrequiredlabel can

Do not display an asterisk

<?php CHtml:: $afterRequiredLabel = ";? ><?php echo $form->labelex ($model, ' email ');?>
