【问题标题】：CodeIgniter File upload not working and not giving errorCodeIgniter 文件上传不起作用且未给出错误

【问题描述】：

我正在尝试从 CodeIgniter 上传文件。文件没有给出任何错误，甚至没有将文件存储在根目录或 codeigniter 中的上传文件夹中。有人可以帮忙吗？请注意，因为我已经向我的上传文件夹授予了 755 权限。下面是我的代码

查看文件

<html>
<head>
<title>Upload Form</title>
</head>
<body>

<?php echo $error;?>

<?php echo form_open_multipart('UploadController');?>

<input type="file" name="userfile" size="20" />

<br /><br />

<input type="submit" value="upload" />

</form>

</body>
</html>

下面是我的控制器

<?php

class UploadController extends CI_Controller {

    function __construct()
    {
        parent::__construct();
        $this->load->helper(array('form', 'url'));
    }

    function index()
    {
        $this->load->view('uploadview', array('error' => ' ' ));
    }

    function do_upload()
    {
        $config['upload_path'] = './uploads/';
        $config['allowed_types'] = 'gif|jpg|png';
        $config['max_size'] = '100';
        $config['max_width']  = '1024';
        $config['max_height']  = '768';

        $this->load->library('upload', $config);

        if ( ! $this->upload->do_upload("add_1"))
        {
            $error = array('error' => $this->upload->display_errors());

            $this->load->view('upload_form', $error);
        }
        else
        {
            $data = array('upload_data' => $this->upload->data());

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

请在这个问题上帮助我。

【解决方案1】：

您的代码中有一些错误：请更改以下行：

1.改变 form_open_multipart('UploadController') 到 form_open_multipart('UploadController/do_upload')

2.改变 $this->upload->do_upload("add_1") 到 $this->upload->do_upload("userfile")。 3.改变 $this->load->view('upload_form', $error); 到
$this->load->view('uploadview', $error);

【解决方案2】：

改变

form_open_multipart('UploadController')

到

form_open_multipart('UploadController/do_upload')

【讨论】：

【解决方案3】：

更改表单操作路径

form_open_multipart('UploadController/do_upload')

或者你可以像这样在一种方法中使用它：

function index()
{
    $config['upload_path']      = 'upload_path';
  $config['allowed_types']    = 'gif|jpg|jpeg|png';
  $config['max_size']         = 5120;
  $config['encrypt_name']     = true;

  $this->load->library('upload', $config);

    $this->form_validation->set_rules('image', 'lang:image', 'file_size_max[5M]|file_allowed_type[image]');

    if($this->form_validation->run() == FALSE)
    {
        $this->load->view('uploadview', array('error' => ' ' ))
    }
    else
    {
        $user = array();

        $uploaded  = $this->upload->do_upload('add_1');

    //delete the original file if another is uploaded
    if($uploaded)
    {           
      $data = array('upload_data' => $this->upload->data());

      $this->load->view('uploadview', $data);
    } else {
      $error = array('error' => $this->upload->display_errors());

      $this->load->view('upload_form', $error);
    }
    }
}

并确保您的上传路径正确。
