PHP and jQuery: send email
Blogs20112011-07-02
I wrote a very compact, simple web app: send email via a web page. The functions use PHP and jQuery(version 1.5.1), include:
- form validation
I use a excellent jQuery plugin: Validation Engine to do the form validation. - Ajax Style send email
use jQuery’s $.ajax(), and ‘click’ event to send email instead of form submit.
(1) the header part: to launch all the need js and css file.
http://js/jquery-1.5.1.min.js
http://js/jquery.validationEngine-en.js
http://js/jquery.validationEngine.js
<link rel="stylesheet" type="text/css" href="css/validationEngine.jquery.css" />(2) form and its javascript action:
<form id="request_form" method="post" action="<?=$_SERVER['PHP_SELF'];?>">
<p>Organization:</p>
<p>Name:</p>
<p>Email:</p>
<p>Phone #:</p>
<input id="request_submit" value="Send Request" type="submit">
</form>
$(document).ready(function() {
$("#request_submit").click( function(event) {
$("#request_form").validationEngine();
event.preventDefault();
if ($("#request_form").validationEngine({returnIsValid:true})) {
alert( $("#request_form").serialize());
$.ajax({
type: $("#request_form").attr('method'),
url: $("#request_form").attr('action'),
data: $("#request_form").serialize(),
success: function(data) {
alert(data);
$("#request_form").append('Successfully send out this email request!');
}
});
}
});
});(3) PHP process:
<?php
if(isset($_POST['email'])) {
if ( !check_email( trim($_POST['email']) )) {
echo 'Please enter a valid email address<br />';
}
else send_email();
}
exit;
function check_email($emailAddress) {
if (preg_match('/b[A-Z0-9._%-]+@[A-Z0-9.-]+.[A-Z]{2,4}b/i', $emailAddress)){
$emailArray = explode("@",$emailAddress);
if (checkdnsrr($emailArray[1])){
return true;
}
}
return false;
}
function send_email() {
$message = "nOrganization: " . $_POST['organization'] .
"nName: " . $_POST['name'] .
"nEmail: " . $_POST['email'] .
"nPhone: " . $_POST['phone'];
$message .= "nnBrowser Info: " . $_SERVER["HTTP_USER_AGENT"] .
"nIP: " . $_SERVER["REMOTE_ADDR"] .
"nnDate: " . date("Y-m-d h:i:s");
$siteEmail = 'test@test.com';
$emailTitle = 'Request from examples.com';
$thankYouMessage = "Thank you for contacting us, we'll get back to you shortly.";
if(! mail($siteEmail, $emailTitle, $message, 'From: ' . $_POST['name'] . ' <' . $_POST['email'] . '>'))
echo 'Mail can not sent.';
}
?>It works pretty cool.
