yii Remove asterisks from required fields_PHP tutorial

How to remove the asterisk in 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);

}

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)www.2cto.com

{

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, and CHtml::afterRequiredLabel in the view

Just do this without showing the asterisk

labelEx($model,'email'); ?>
