Email validation using JavaScript and Jquery

Email validation using JavaScript and Jquery :

 Here i will explain how to validate email id with JQuery. In JavaScript we can check the email id format only. but in jquery we can check whether we allow or not some of domain names also. First i will explain basic javascript method to validate email id.

Here is Javascript method :

function validateEmail(emailId)
{
var condition = /^([a-zA-Z0-9_.+-])+\@(([a-zA-Z0-9-])+\.)+([a-zA-Z0-9]{2,4})+$/;
return condition.test(emailId);
}

In this javascript method only validate the given email id has alphabets and numeric. Here the variable "condition" has the email conditions. that is

([a-zA-Z0-9_.+-]) - is to allow email id username with  alphabets and numeric and also _.
@(([a-zA-Z0-9-]) - is to allow domail name with alphabets and numeric . and
([a-zA-Z0-9]{2,4}) - is to allow last part of the email id i.e., com, in, .. with alphabets and numeric and also                                   it's length should be 2 to 4.

Now i will explain how to validate email id with JQuery.

Here is JQuery Method :

$(document).ready(function() {

  $('#submitButton').click(function() {

    var emailCon = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;
    var emailblockCon =/^([\w-\.]+@(?!gmail.com)(?!yahoo.com)([\w-]+\.)+[\w-]{2,4})?$/;

    var emailId = $("#mailId").val();
    if(emailId == '') {
      $("#mailId").val('Email id is Blank.');
      error = true
    }

    else if(!emailCon.test(emailId)) {
      $("#mailId").val('Check Your Email id.');
      error = true
    }

    else if(!emailblockCon.test(emailId)) {
      $("#mailId").val('gmail and yahoo mail ids not accept.');
      error = true
    }

    if(error == true) {
           return false;
    }

    });
}); 

In this JQuery method you can check the email format like in javascript . In jquery we validate extra one condition. here we validate the email id domain name also. because some of the website doesnt allow some free email providers domain. so we can also validate it here.

Attachment in mail using PHP

Attachment in mail using PHP



In the previous post, I described HTML content in mails. In this post we can see how attachment in mails can be done using PHP .




$to = 'youraddress@example.com';
//define the subject of the email
$subject = 'Test email with attachment';
//create a boundary string. It must be unique
//so we use the MD5 algorithm to generate a random hash
$random_hash = md5(date('r', time()));
//define the headers we want passed. Note that they are separated with \r\n
$headers = "From: webmaster@example.com\r\nReply-To: webmaster@example.com";
//add boundary string and mime type specification
$headers .= "\r\nContent-Type: multipart/mixed; boundary=\"PHP-mixed-".$random_hash."\"";
//read the atachment file contents into a string,
//encode it with MIME base64,
//and split it into smaller chunks
$attachment = chunk_split(base64_encode(file_get_contents('attachment.zip')));
//define the body of the message.
ob_start(); //Turn on output buffering
?>
--PHP-mixed-
Content-Type: multipart/alternative; boundary="PHP-alt-"

--PHP-alt-
Content-Type: text/plain; charset="iso-8859-1"
Content-Transfer-Encoding: 7bit

Hello World!!!
This is simple text email message.

--PHP-alt-
Content-Type: text/html; charset="iso-8859-1"
Content-Transfer-Encoding: 7bit

TechniqZone Is Help To Guide Developers issues

This is something with HTML formatting.

--PHP-alt---

--PHP-mixed-
Content-Type: application/zip; name="attachment.zip"
Content-Transfer-Encoding: base64
Content-Disposition: attachment


--PHP-mixed---

//copy current buffer contents into $message variable and delete current output buffer
$message = ob_get_clean();
//send the email
$mail_sent = @mail( $to, $subject, $message, $headers );
//if the message is sent successfully print "Mail sent". Otherwise print "Mail failed"
echo $mail_sent ? "Mail sent" : "Mail failed";
?>
