我尝试将这个RECaptcha-for-Codeigniter用于我的旧网站之一，编码非常古老。
我的页面中没有加载重新验证码。
我使用过这个：https://github.com/Cnordbo/RECaptcha-for-Codeigniter
代码：/application/modules_core/register/controllers/register.php

确定。我想问题是你在构造函数中调用了recaptcha_get_html（）函数，因此当你从索引函数加载视图时，它的作用域位于构造函数中。
试试这个 -
public function __construct()
{
parent::__construct();
$this->load->library('recaptcha');
$this->load->library('form_validation');
$this->load->helper('form');
$this->load->library('session');
$this->load->model('index/user_model');
$this->output->set_header("Cache-Control: no-store, no-cache, must-revalidate, no-transform, max-age=0, post-check=0, pre-check=0");
$this->output->set_header("Pragma: no-cache");
$data = $this->recaptcha->recaptcha_get_html();
$this->index($data);
}
并在索引函数中编写如 -
public function index($captcha)
{
$data['recaptcha_html']= $captcha;
// rest of your code
......
}

它会像这样工作......
从controllers / register.php中移除captacha条目：public function __construct（）
只需在controllers / register.php
中使用它public function index()
{
$this->load->library('recaptcha');
$data['recaptcha_html'] = $this->recaptcha->recaptcha_get_html();
$data['page'] = 'register/content';
你可以休息。
