表单提交时发送邮件

1. 首先在phpcms后台找到邮箱配置
   
2. 在后台设置->模块->表单向导添加接收邮件，即可实现前台表单提交邮箱收到邮件功能
   
3. 一般情况下这个时候收到的邮件都是空白的，所以要去修改PHP代码
   找到 /phpcms/modules/formguide/index.php
   找到 foreach ($mails as $m) { sendmail($m, L('tips'), $this->M['mailmessage']); } 替换为

   $f_info = $this->db->get_one(array('modelid'=>$formid, 'siteid'=>$this->siteid));

   $MailSubject = '用户提交表单['.$f_info['name'].']提醒';

   $Fields = getcache('formguide_field_'.$formid, 'model');

   $Fields['username']['name'] = '用户名';

   $Fields['datetime']['name'] = '提交时间';

   $Fields['ip']['name'] = '提交IP';

   unset($data['userid'], $data['datetime']);

   foreach($data as $k=>$v){

   $MailBody .= $Fields[$k]['name'].'：'.$v.'<br />';

   }

   foreach ($mails as $m) {

   sendmail($m, $MailSubject, $MailBody.$this->M['mailmessage']);

   }
