特定域的电子邮件验证

标签: javascript php validation

我需要电子邮件验证方面的帮助,这个验证码所有的电子邮件都是特定格式的,例如test@test.gov.au,test@something.ac.au,我希望它的格式为test@something.au < / p>

(注意:这里我只允许进入5个域名,即gov.au,edu.au,govt.nz,ac.au和csiro.au)

我的代码如下

JS:

function emailTldValidation(tlds) {
            $.validator.addMethod("emailTld", function(value,element) {
              if (value.search("@") != -1) {
                    return (/(.+)@(.+)\.(gov\.au|edu\.au|ac\.nz|csiro\.au|govt\.nz)$/).test(value);
                    //return (/(.+)@(.+)\.(csiro\.au|gov|gov\.us)$/).test(value);
                }
                return false;
            },"Please enter valid tld like "+tlds); 

            $.validator.addClassRules({
                stringInput: {
                    emailTld: true
                }
            });
        }

以下代码在function.php中验证

function validateEmail($email) {
        //validate email here from server side
        if(filter_var($email, FILTER_VALIDATE_EMAIL)) {
            //validate tld
            $validTlds = str_replace(".", "\.", VALID_EMAIL_TLDS);
            $validTlds = "\.".str_replace(",", "|\.", $validTlds);
            $emailArr = explode("@", $email);
            $emailTld = $emailArr[1];
            if (preg_match('/^[-a-z0-9]+\.[a-z][a-z]|('.$validTlds.')\z/', strtolower($emailTld))) {
                //check main domain here
                $exValidTlds = explode(",", VALID_EMAIL_TLDS);
                $exValidTlds = array_map('trim', $exValidTlds);
                foreach($exValidTlds as $tld) {//if exist then
                    if(strstr($emailTld, ".".$tld)) {
                        if($tld == strrchr($emailTld, $tld)) {
                            return true;
                        }
                    }
                }
                return false;
            }
        }

function validateEmail($email) {
		//validate email here from server side
		if(filter_var($email, FILTER_VALIDATE_EMAIL)) {
			//validate tld
			$validTlds = str_replace(".", "\.", VALID_EMAIL_TLDS);
			$validTlds = "\.".str_replace(",", "|\.", $validTlds);

			//$validTlds = str_replace(",", "|\.", $validTlds);
			$emailArr = explode("@", $email);

			$emailTld = $emailArr[1];
			
			if ($emailTld == 'csiro.au')
			{
				//check main domain here
				
				return true;
			
			}
			elseif (preg_match('/^[-a-z0-9]+('.$validTlds.')\z/', strtolower($emailTld))) {
			
			
				//check main domain here
				$exValidTlds = explode(",", VALID_EMAIL_TLDS);
				$exValidTlds = array_map('trim', $exValidTlds);
				foreach($exValidTlds as $tld) {//if exist then

					if(strstr($emailTld, ".".$tld)) {
						if($tld == strrchr($emailTld, $tld)) {
							return true;
						}
					}
				}
				return false;
			}
		}
		return false;

这个正则表达式对我来说非常好:

.+@(?:(?:govt*)|(?:edu)|(?:ac)|(?:csiro))\.(?:au|nz)

仅供参考,验证电子邮件难以置信困难:http://www.ex-parrot.com/pdw/Mail-RFC822-Address.html

编辑:重新阅读您的问题后,您似乎可能需要验证包含子域名的电子邮件等。这可能更适合更开放的域名:

.+@(?:\w+\.\w+)

编辑2:问题是你的验证太复杂了。

.+@(?:(?:.+\.(?:(?:govt*)|(?:edu)|(?:ac))\.(?:au|nz))|(?:csiro\.au))

打破它:

.+         // Match at least 1 of any character
@          // An @ symbol
(?:        // The group of everything right of the @ symbol
(?:        // The group of domains that have subdomains
.+\.       // At least one character in front of a .
(?:        // govt, edu or ac
\.         // a dot
(?:        // au or nz
(?:        // or simply 'csiro.au'

你无法解决这样一个事实:你的四个域需要一个子域,而另一个域则不需要。
