电子邮件以2种格式接受，即abc.def和[e-mail]

Question

I need emails to be validated as a EMAIL([e-mail]) and at the same time as a USERNAME (abc.def). I have used Yii EMAIL Validation which is strict validation but i have not to change it because it is using in many other places in the project.

However, i need to add CUSTOM USERNAME VALIDATION along with YII EMAIL VALIDATION for a single MODEL.

Below is the Code to do that.

public function rules() {
    $rules = array(
        array('email', 'required', 'message'=>'Please complete {attribute}'),
        array('email', 'EmailCustom'),
        array('email', 'unique')
    );
}

Whereas EmailCustom Validator Class is:

class EmailCustom extends CEmailValidator
{
    public $pattern = '/^[ ]*[a-zA-Z0-9!#$%&\'*+\\/=?^_`’{|}~-]+(?:\.[a-zA-Z0-9!#$%&\'*+\\/=?^_`’{|}~-]+)*@(?:[a-zA-Z0-9](?:[a-zA-Z0-9-]*[a-zA-Z0-9])?\.)+[a-zA-Z0-9](?:[a-zA-Z0-9-]*[a-zA-Z0-9])?[ ]*$/';

    protected function validateAttribute($object, $attribute)
    {
        $pattern = '/^[ ]*[a-zA-Z0-9!#$%&\'*+\\/=?^_`’{|}~-]+(?:\.[a-zA-Z0-9!#$%&\'*+\\/=?^_`’{|}~-]+)*@(?:[a-zA-Z0-9](?:[a-zA-Z0-9-]*[a-zA-Z0-9])?\.)+[a-zA-Z0-9](?:[a-zA-Z0-9-]*[a-zA-Z0-9])?[ ]*$/';
        if ($object->visitor_card_status == 2) {
            if (!preg_match($pattern, $object->$attribute)) {
                if ($object->$attribute !== $object->first_name . '.' . $object->last_name) {
                    $this->addError($object, $attribute, 'Email is incorrect format');
                }
            }
        } else {
            if (!preg_match($pattern, $object->$attribute)) {
                $this->addError($object, $attribute, 'Email is incorrect format');
            }
        }
    }

    public function clientValidateAttribute($object, $attribute)
    {
        if ($this->validateIDN)
        {
            Yii::app()->getClientScript()->registerCoreScript('punycode');
            // punycode.js works only with the domains - so we have to extract it before punycoding
            $validateIDN='
                            var info = value.match(/^(.[^@]+)@(.+)$/);
                            if (info)
                                value = info[1] + "@" + punycode.toASCII(info[2]);
                            ';
        } else {
            $validateIDN = '';
        }

        $message = $this->message!==null ? $this->message : Yii::t('yii','{attribute} is not in a recognised format. <span style="text-transform:capitalize;">Please </span>revise.');
        $message = strtr($message, array(
            '{attribute}'=>$object->getAttributeLabel($attribute),
        ));
}

So, What should be added in the pattern of Validator Class to accept only two FORMATS: abc.def and [e-mail]

Hope to hear from you soon. Thanks

Answer 1

Actually, I have updated the pattern which accepts both the formats and using the Yii Validator function does the trick.

Below is the pattern to accept both the format. i.e. abc.def and [e-mail]

/(^[ ]*[a-zA-Z0-9!#$%&\'*+\\/=?^_`’{|}~-]+(?:\.[a-zA-Z0-9!#$%&\'*+\\/=?^_`’{|}~-]+)*@(?:[a-zA-Z0-9](?:[a-zA-Z0-9-]*[a-zA-Z0-9])?\.)+[a-zA-Z0-9](?:[a-zA-Z0-9-]*[a-zA-Z0-9])?[ ]*$)|([a-zA-Z0-9]+\.[a-zA-Z0-9]+)/

I hope it may help others. Thanks
