Codeigniter,空白页,没有错误

Question

public function newreg()
    {
        $username = $this->input->post('username');
        $password = $this->input->post('password');

        $this->load->model('register_model');

        $data['list']=$this->register_model->add($username, $password);

        $this->load->view('register_display', $data);
    }

调用此函数后,这是一个名为register.php的控制器的一部分,我在屏幕上看到的只是空格.

此功能是工作控制器的工作副本的精确副本.仅更改文件名(模型,视图)

我无法弄清楚问题出在哪里.

你可以通过enalbing轻松检查enteire envoir中发生的事情CI logs,

去config/config.php编辑这个:

/*
|--------------------------------------------------------------------------
| Error Logging Threshold
|--------------------------------------------------------------------------
|
| If you have enabled error logging, you can set an error threshold to
| determine what gets logged. Threshold options are:
| You can enable error logging by setting a threshold over zero. The
| threshold determines what gets logged. Threshold options are:
|
|   0 = Disables logging, Error logging TURNED OFF
|   1 = Error Messages (including PHP errors)
|   2 = Debug Messages
|   3 = Informational Messages
|   4 = All Messages
|
| For a live site you'll usually only enable Errors (1) to be logged otherwise
| your log files will fill up very fast.
|
*/


  $config['log_threshold'] = 0; //put this to 4

然后,如果您还没有/logs/ application文件夹中的文件夹,请创建该文件夹并添加775 chmod到该文件夹​​(仅限日志文件夹).

更新: 您还必须chown apache:apache logs让apache能够在该文件夹中写入.

通过浏览器运行您的应用程序并在/logs文件夹中检查log.php文件,它将包含all the application errors.
