Codeigniter 表单发布数据为空

Posted 2023-02-25

【中文标题】Codeigniter 表单发布数据为空

【英文标题】：Codeigniter Forms Post Data is empty

【发布时间】：2021-06-26 16:09:52

【问题描述】：

我一直在尝试在 xampp 中本地设置现有的 CI 3.1 项目。数据库已连接，网站已加载，但登录/注册/表单无法正常工作。

详细检查后发现表单未在发布数据中发送。帖子对象为空。

下面是代码。

【问题讨论】：

您的Sign up 函数似乎是一个锚标记，因此它只会在单击时导航（不提交表单数据）。 SIGN IN 按钮应该正在发送数据。也许尝试将 var_dump($_POST); die(); 放在 Auth 控制器的顶部以验证您是否正在接收表单数据？

@dnapierata 我试过调试，帖子返回空。

【参考方案1】：

尝试先获取输入，然后将其传递给模型... 在您的控制器 Auth/login 中输入此代码

$email = $this->security->xss_clean($this->input->post('email')); $password = $this->security->xss_clean($this->input->post('password'));

然后通过调用将其传递给您的模型验证/验证

$result = $this->AuthModel->validate($email, $password);

代码应该是这样的...

    // Load the model
    $this->load->model('AuthModel');
    // Validate the user can login
    $result = $this->AuthModel->validate($email, $password);
    var_dump($_POST);
    // Now we verify the result
    if(!$result)
