在codeigniter的helper用phpmailer 发送邮件

首先下载phpmailer http://sourceforge.net/projects/phpmailer/files/phpmailer%20for%20php5_6/PHPMailer%20v5.1/，

解压缩后放到codeigniter的根目录吧，方便引用

然后在helper文件里 写入如下函数

function send_mail($to,$title,$body)
{
	$ci =& get_instance();
	require_once('phpmailer/class.phpmailer.php');
	require_once('phpmailer/class.smtp.php');
	
	$mail = new PHPMailer(true); // the true param means it will throw exceptions on errors, which we need to catch

	$mail->IsSMTP(); // telling the class to use SMTP

	try {
	  $mail->Host       = $ci->config->item('mail_smtp'); // SMTP server
	  $mail->SMTPDebug  = false;                     // enables SMTP debug information (for testing)
	  $mail->SMTPAuth   = true;                  // enable SMTP authentication
	  $mail->Port       = $ci->config->item('mail_port');                    // set the SMTP port for the GMAIL server
	  
	  $mail->Username   = $ci->config->item('mail_address'); // SMTP account username
	  $mail->Password   = $ci->config->item('mail_passwd');        // SMTP account password
	  
	  $mail->AddAddress('[email protected]', '');
	  $mail->SetFrom($ci->config->item('mail_address'), $ci->config->item('mail_name'));
	 
	  $mail->Subject = $title;
	  $mail->MsgHTML($body);
	  
	  $mail->Send();
	  return true;
	} catch (phpmailerException $e) {
	  //echo $e->errorMessage(); //Pretty error messages from PHPMailer
	  return false;
	} catch (Exception $e) {
	  //echo $e->getMessage(); //Boring error messages from anything else!
	  return false;
	}
		
}

另外在config里写入你的邮箱配置项

$config['mail_name']='焦常云';
$config['mail_passwd']='password';
$config['mail_address']='[email protected]';
$config['mail_smtp']='smtp.21cn.com';
$config['mail_smtp_port']=25;
