谁能帮我解决这个问题"An Error Was Encountered Non-existent class: recaptchalib"

Question

我正在将 recaptcha 库更新为 recaptchalib。

我遇到了这个错误。

An Error Was Encountered Non-existent class: recaptchalib

1. 在库文件夹中包含库 recaptchalib.php。
2. 用户控制器：

    $this->load->library('recaptchalib');

    $data['fincaptcha_ok'] = $this->recaptchalib->recaptcha_get_html();

    $this->recaptchalib->recaptcha_check_answer($_SERVER['REMOTE_ADDR'],$this->input->post('recaptcha_challenge_field'),$this->input->post('recaptcha_response_field'));
    if(!$this->recaptchalib->getIsValid()) {
        $this->load->helper('directory');
        $data['error'] = 'incorrect captcha';
        $data['body_content']           = 'user/register';
        $this->load->view('template', $data);

3. 查看：<?php echo $fincaptcha_ok; ?>

如果我错了请纠正我，但我认为你使用 this recaptcha 库。

这个库提供了一组函数，没有对象实现。那就是说，如果您像这样使用它应该可以工作：

$this->load->library('recaptchalib');

$data['fincaptcha_ok'] = recaptcha_get_html();

$objResponse = recaptcha_check_answer($_SERVER['REMOTE_ADDR'],$this->input->post('recaptcha_challenge_field'),$this->input->post('recaptcha_response_field'));

if(!$objResponse->is_valid) 
{
    $this->load->helper('directory');
    $data['error'] = 'incorrect captcha';
    $data['body_content']           = 'user/register';
    $this->load->view('template', $data);
}

As an additional information, eventually it's better to use the built in captcha helper. Take a closer look at their documenation here.
