四：验证函数


/Application/Common/Common/function.php


/**
 * geetest检测验证码
 */
function geetest_chcek_verify($data){
  $geetest_id=C('GEETEST_ID');
  $geetest_key=C('GEETEST_KEY');
  $geetest=new \Org\Xb\Geetest($geetest_id,$geetest_key);
  $user_id=$_SESSION['geetest']['user_id'];
  if ($_SESSION['geetest']['gtserver']==1) {
    $result=$geetest->success_validate($data['geetest_challenge'], $data['geetest_validate'], $data['geetest_seccode'], $user_id);
    if ($result) {
      return true;
    } else{
      return false;
    }
  }else{
    if ($geetest->fail_validate($data['geetest_challenge'],$data['geetest_validate'],$data['geetest_seccode'])) {
      return true;
    }else{
      return false;
    }
  }
}


PHP
多谢 香蕉你个banana 童鞋的提醒；补上验证的函数；


五：php 生成验证码 并 验证
/Application/Home/Controller/IndexController.class.php


/**
 * geetest生成验证码
 */
public function geetest_show_verify(){
  $geetest_id=C('GEETEST_ID');
  $geetest_key=C('GEETEST_KEY');
  $geetest=new \Org\Xb\Geetest($geetest_id,$geetest_key);
  $user_id = "test";
  $status = $geetest->pre_process($user_id);
  $_SESSION['geetest']=array(
    'gtserver'=>$status,
    'user_id'=>$user_id
    );
  echo $geetest->get_response_str();
}
/**
 * geetest submit 提交验证
 */
public function geetest_submit_check(){
  $data=I('post.');
  if (geetest_chcek_verify($data)) {
    echo '验证成功';
  }else{
    echo '验证失败';
  }
}
/**
 * geetest ajax 验证
 */
public function geetest_ajax_check(){
  $data=I('post.');
  echo intval(geetest_chcek_verify($data));
}
