Contact PHP stopped working?

[dubstarr]

I tested the site before it went live and it worked. That was a few weeks ago. Just realized today that it isn’t sending the emails. Well, at least I think it’s not sending. I send test messages to myself directly to the email address and it works that way. Just not receiving client email inquiries. YIKES!!!

[php]<?php
define(‘TO_EMAIL’, ‘“Anthony Andrews” [email protected]’);

class Mailer{

private $_params;
private $_errors;

public function __construct(){
    $this->_params = $this->LoadParams();
    $this->_errors = array();
}

public function run(){	
    if($this->Validate()){
        $res = $this->SendEmail();
        if($res === true)
            $this->OnSuccess();
        else
            $this->OnError();	
    }else
        $this->OnError();		
}

private function LoadParams(){
    return $_POST['contact'];
}

private function Validate(){
    if(!(isset($this->_params['name']) && ($this->_params['name'] != '')))
        $this->_errors['name'] = 'empty_name';
    if(!(isset($this->_params['email']) && $this->_params['email'] != ''))
        $this->_errors['email'] = 'empty_email';
    else{
        $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
        if(!preg_match($email_exp,$this->_params['email']))
            $this->_errors['email'] = 'invalid';
    }
    if(!(isset($this->_params['subject']) && $this->_params['subject'] != ''))
        $this->_errors['subject'] = 'empty_subject';
    if(!(isset($this->_params['message']) && $this->_params['message'] != ''))
        $this->_errors['message'] = 'empty_message';
    
    return (count($this->_errors) == 0);
}

private function SendEmail(){
    $headers = 
        'From: "' . $this->_params['name'] . '" <' . $this->_params['email'] . ">\r\n" .
        'Reply-To: "' . $this->_params['name'] . '" <' . $this->_params['email'] . ">\r\n" .
        'X-Mailer: PHP/' . phpversion();
    
    $to = TO_EMAIL;       
    return mail($to, $this->_params['subject'], $this->_params['message'], $headers);
}

private function OnSuccess(){        
    echo '{"success": true}';
}

private function OnError(){
    $response = '{';
    $response .= '"success": false, "errors": [';
    
    foreach($this->_errors as $key => $value) {  
        $response .= "{ \"field\": \"$key\", \"error\": \"$value\"},";
    }
    if(count($this->_errors) > 0)
        $response = substr($response, 0, -1);
    $response .= ']}';
    
    echo $response;
}

}
$mailer = new Mailer();
$mailer->run();
?>[/php]

Any help would be greatly appreciated.

If you add try/catch blocks to your code, you might be able to see where it’s failing
