来源：互联网发布：美化字体的软件编辑：程序博客网时间：2024/04/29 06:34

步骤1、在\phpcms\templates\default\formguide\show.html 中添加验证码显示

<input type="text" id="code" name="code" size="8"class="input-text">{form::checkcode('code_img', '4','14', 84, 24)}

步骤2、在 \phpcms\modules\formguide\index.php 中修改

具体如下

<?php
defined('IN_PHPCMS') or exit('No permission resources.');
define('CACHE_MODEL_PATH',PHPCMS_PATH.'caches'.DIRECTORY_SEPARATOR.'caches_model'.DIRECTORY_SEPARATOR.'caches_data'.DIRECTORY_SEPARATOR);
$session_storage ='session_'.pc_base::load_config('system','session_storage'); //判断验证码
pc_base::load_sys_class($session_storage); //判断验证码
class index {

private $db, $m_db, $M;
function __construct() {
  $this->db =pc_base::load_model('sitemodel_model');
  $this->m_db =pc_base::load_model('sitemodel_field_model');
  $this->M =new_html_special_chars(getcache('formguide', 'commons'));
  $this->siteid =get_siteid();
  $this->M =$this->M[$this->siteid];

找到下面代码

if(isset($_POST['dosubmit'])) {

$tablename = 'form_'.$r['tablename'];
$this->m_db->change_table($tablename);

在下方加入：

   if(!empty($_SESSION['code'])){
    //判断验证码
    $code= isset($_POST['code']) &&trim($_POST['code']) ? trim($_POST['code']) :showmessage(L('input_code'), HTTP_REFERER);
    if($_SESSION['code'] != strtolower($code)) {
     showmessage(L('code_error'),HTTP_REFERER);
    }
   }
