Contact Form working in Chrome, not in IE/Firefox - php

Question

Having some trouble with the contact form on my website, http://www.techcom.co.nz/
It works fine on google chrome, however on IE and Firefox it doesn't send any message and just redirects back up to the top of the page/refreshes the page.
Here is the php code for the form:
// EDIT THE FOLLOWING LINE BELOW AS REQUIRED
$send_email_to = "techcomnz#gmail.com";
function send_email($name,$email,$email_subject,$email_message)
{
global $send_email_to;
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=iso-8859-1" . "\r\n";
$headers .= "From: ".$email. "\r\n";
$message = "<strong>Email = </strong>".$email."<br>";
$message .= "<strong>Name = </strong>".$name."<br>";
$message .= "<strong>Message = </strong>".$email_message."<br>";
#mail($send_email_to, $email_subject, $message,$headers);
return true;
}
function validate($name,$email,$message,$subject)
{
$return_array = array();
$return_array['success'] = '1';
$return_array['name_msg'] = '';
$return_array['email_msg'] = '';
$return_array['message_msg'] = '';
$return_array['subject'] = '';
if($email == '')
{
$return_array['success'] = '0';
$return_array['email_msg'] = 'email is required';
}
else
{
$email_exp = '/^[A-Za-z0-9._%-]+#[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
if(!preg_match($email_exp,$email)) {
$return_array['success'] = '0';
$return_array['email_msg'] = 'enter valid email.';
}
}
if($name == '')
{
$return_array['success'] = '0';
$return_array['name_msg'] = 'name is required';
}
else
{
$string_exp = "/^[A-Za-z .'-]+$/";
if (!preg_match($string_exp, $name)) {
$return_array['success'] = '0';
$return_array['name_msg'] = 'enter valid name.';
}
}
if($subject == '')
{
$return_array['success'] = '0';
$return_array['subject_msg'] = 'subject is required';
}
if($message == '')
{
$return_array['success'] = '0';
$return_array['message_msg'] = 'message is required';
}
else
{
if (strlen($message) < 2) {
$return_array['success'] = '0';
$return_array['message_msg'] = 'enter valid message.';
}
}
return $return_array;
}
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
$subject = $_POST['subject'];
$return_array = validate($name,$email,$message,$subject);
if($return_array['success'] == '1')
{
send_email($name,$email,$subject,$message);
}
header('Content-type: text/json');
echo json_encode($return_array);
die();
?>
and here is the html:
<fieldset id="contact_form">
<div id="msgs"> </div>
<form id="cform" name="cform" method="post" action="">
<input type="text" id="name" name="name" value="Full Name*" onfocus="if(this.value == 'Full Name*') this.value = ''"
onblur="if(this.value == '') this.value = 'Full Name*'" />
<input type="text" id="email" name="email" value="Email Address*" onfocus="if(this.value == 'Email Address*') this.value = ''"
onblur="if(this.value == '') this.value = 'Email Address*'" />
<input type="text" id="subject" name="subject" value="Subject*" onfocus="if(this.value == 'Subject*') this.value = ''"
onblur="if(this.value == '') this.value = 'Subject*'" />
<textarea id="msg" name="message" onfocus="if(this.value == 'Your Message*') this.value = ''"
onblur="if(this.value == '') this.value = 'Your Message*'">Your Message*</textarea>
<button id="submit" class="button" style=""> Send Message</button>
</form>
</fieldset>
Any help would be greatly appreciated.

Leaving the action attribute blank will cause most browsers to submit the form data to the current page by reloading it with the data in GET or POST.
If this is your intention, try removing the action="" altogether as it has been known to cause issues with older browsers.
