PHP Mailer form not sending emails?

PHP
1

Hi I am using a form on a site that a user fills in some basic details that are then sent to an email address. Nothing fancy but I’m using ajax to process the form just so it looks a bit better from the users point of view.
Problem is the form is not sending the emails.
Everything looks to be working fine but the email never arrives.

Here’s the form code:

<div id="quick-form-header">Contact Form</div>
    <div id="quick-form">
    <form id="contact-form" name="contact-form" method="post" action="submit.php">
      <table width="100%" border="0" cellspacing="0" cellpadding="5">
        <tr>
          <td width="15%"><label for="name">Name</label></td>
          <td width="70%"><input type="text" class="validate[required,custom[onlyLetter]]" name="name" id="name" value="<?=$_SESSION['post']['name']?>" /></td>
          <td width="15%" id="errOffset">&nbsp;</td>
        </tr>
        <tr>
          <td><label for="email">Email</label></td>
          <td><input type="text" class="validate[required,custom[email]]" name="email" id="email" value="<?=$_SESSION['post']['email']?>" /></td>
          <td>&nbsp;</td>
        </tr>
        <tr>
          <td><label for="phone">Phone</label></td>
          <td><input type="text" class="validate[required,custom[onlyNumber]]" name="phone" id="phone" value="<?=$_SESSION['post']['phone']?>" /></td>
          <td>&nbsp;</td>
        </tr>
        <tr>
          <td><label for="subject">Contact</label></td>
          <td><select name="subject" id="subject">
            <option value="" selected="selected"> - Choose -</option>
            <option value="Email">Email</option>
            <option value="Phone">Phone</option>
            </select></td>
          <td>&nbsp;</td>
        </tr>
        <tr>
          <td valign="top"><label for="message">Message</label></td>
          <td><textarea name="message" id="message" class="validate[required]" cols="35" rows="5"><?=$_SESSION['post']['message']?>I would like to...</textarea></td>
          <td valign="top">&nbsp;</td>
        </tr>
        <tr>
          <td><label for="captcha"><?=$_SESSION['n1']?> + <?=$_SESSION['n2']?> =</label></td>
          <td><input type="text" class="validate[required,custom[onlyNumber]]" name="captcha" id="captcha" /></td>
          <td valign="top">&nbsp;</td>
        </tr>
        <tr>
          <td valign="top">&nbsp;</td>
          <td colspan="2"><input type="submit" name="button" id="button" value="Submit" />
          <input type="reset" name="button2" id="button2" value="Reset" />
          
          <?=$str?>          <img id="loading" src="img/ajax-load.gif" width="16" height="16" alt="loading" /></td>
        </tr>
      </table>
      </form>
      <?=$success?></div>

Here is the php code from the top of the page:

<?php

session_name("fancyform");
session_start();


$_SESSION['n1'] = rand(1,20);
$_SESSION['n2'] = rand(1,20);
$_SESSION['expect'] = $_SESSION['n1']+$_SESSION['n2'];


$str='';
if($_SESSION['errStr'])
{
	$str='<div class="error">'.$_SESSION['errStr'].'</div>';
	unset($_SESSION['errStr']);
}

$success='';
if($_SESSION['sent'])
{
	$success='<h1>Thank you!</h1>';
	
	$css='<style type="text/css">#contact-form{display:none;}</style>';
	
	unset($_SESSION['sent']);
}
?>

Finally this is the php script that actually sends the email if the form has been filled in correctly.

<?php

/* config start */

$emailAddress = 'me@test.com';

/* config end */


require "phpmailer/class.phpmailer.php";

session_name("fancyform");
session_start();


foreach($_POST as $k=>$v)
{
	if(ini_get('magic_quotes_gpc'))
	$_POST[$k]=stripslashes($_POST[$k]);
	
	$_POST[$k]=htmlspecialchars(strip_tags($_POST[$k]));
}


$err = array();

if(!checkLen('name'))
	$err[]='The name field is too short or empty!';
	
if(!checkLen('phone'))
	$err[]='The phone field is too short or empty!';

if(!checkLen('email'))
	$err[]='The email field is too short or empty!';
else if(!checkEmail($_POST['email']))
	$err[]='Your email is not valid!';

if(!checkLen('subject'))
	$err[]='You have not selected a subject!';

if(!checkLen('message'))
	$err[]='The message field is too short or empty!';

if((int)$_POST['captcha'] != $_SESSION['expect'])
	$err[]='The captcha code is wrong!';


if(count($err))
{
	if($_POST['ajax'])
	{
		echo '-1';
	}

	else if($_SERVER['HTTP_REFERER'])
	{
		$_SESSION['errStr'] = implode('<br />',$err);
		$_SESSION['post']=$_POST;
		
		header('Location: '.$_SERVER['HTTP_REFERER']);
	}

	exit;
}


$msg=
'Name:	'.$_POST['name'].'<br />
Phone:	'.$_POST['phone'].'<br />
Email:	'.$_POST['email'].'<br />
IP:	'.$_SERVER['REMOTE_ADDR'].'<br /><br />

Message:<br /><br />

'.nl2br($_POST['message']).'

';


$mail = new PHPMailer();
$mail->IsMail();

$mail->AddReplyTo($_POST['email'], $_POST['name']);
$mail->AddAddress($emailAddress);
$mail->SetFrom($_POST['email'], $_POST['name']);
$mail->Subject = "A new enquiry from Website";

$mail->MsgHTML($msg);

$mail->Send();


unset($_SESSION['post']);

if($_POST['ajax'])
{
	echo '1';
}
else
{
	$_SESSION['sent']=1;
	
	if($_SERVER['HTTP_REFERER'])
		header('Location: '.$_SERVER['HTTP_REFERER']);
	
	exit;
}

function checkLen($str,$len=2)
{
	return isset($_POST[$str]) && strlen(strip_tags($_POST[$str])) > $len;
}

function checkEmail($str)
{
	return preg_match("/^[\\.A-z0-9_\\-\\+]+[@][A-z0-9_\\-]+([.][A-z0-9_\\-]+)+[A-z]{1,4}$/", $str);
}

?>

I’m having to use phpmailer4 due to the version of php on the server I’m having to work on.

Can anyone see where the issues are with this or even give me some pointers as to how I can get this to show any errors while its going through the process.

any help will be much appreciated. Thanks in advance.
