Question

我已经编写了关于图像上传的代码，但它在byexost服务器中无效。我在服务器的根位置下创建了"uploads/products"目录，该文件夹也是可写的，但它仍然无法正常工作。请帮忙。

我打开了应用程序的错误日志记录。如果我访问"application/logs"目录的日志文件，则会显示以下错误。

错误 - 2018-03-25 00:47:08 - ＆gt; 404找不到页面：/ index

错误 - 2018-03-25 00:58:24 - ＆gt;上传路径似乎不是   有效的。

byexost服务器中图片上传目录的图片

我的产品控制器代码。

if(isset($_FILES['productimage']['name'])){
    $filename = $_FILES['productimage']['name']; 
    $config['file_name'] = $filename;
    $config['upload_path'] = realpath(FCPATH.'uploads/products/');
    $config['allowed_types'] = 'jpg|jpeg|png';    
    $config['remove_spaces'] = TRUE;
    $config['encrypt_name'] = TRUE;
    $config['min_width'] = 360;
    $config['min_height'] = 360;
    $config['max_width'] = 360;
    $config['max_height'] = 360;
    $this->upload->initialize($config);
    if($this->upload->do_upload('productimage')){
        $uploadeddata = $this->upload->data();
        $data['image'] = $uploadeddata['file_name'];
    }else{
            $this->session->set_flashdata('error', $this->upload->display_errors());
            $result = array("status"=>false, "message"=>$this->upload->display_errors());
    }

}

Answer 1

检查upload_tmp_dir权限（PHP使用的权限）。原生文件上传分为两步：上传到tmp目录并移动到你想要的任何内容。

另请确保您尝试上传符合upload limit的文件。

Answer 2

创建档案upload_form.php＆amp;放置它application/views/文件夹：

<html>
    <head>
        <title>Upload Form</title>
    </head>
    <body>
        <?php echo $error;?>
        <?php echo form_open_multipart('upload/do_upload');?>
            <input type="file" name="userfile" size="20" />
            <br /><br />
            <input type="submit" value="upload" />
        </form>
    </body>
</html>

创建upload_success.php并将其application/views/文件夹：

<html>
    <head>
        <title>Upload Form</title>
    </head>
    <body>
        <h3>Your file was successfully uploaded!</h3>
        <ul>
            <?php foreach ($upload_data as $item => $value):?>
                <li><?php echo $item;?>: <?php echo $value;?></li>
            <?php endforeach; ?>
        </ul>
        <p><?php echo anchor('upload', 'Upload Another File!'); ?></p>
    </body>
</html>

将其命名为upload.php并将其放在application/controllers/文件夹中：

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

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

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

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

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

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

代码点火器的REST过程与通常相同。在/htdocs/codeigniter/文件夹中创建上传文件夹。如果您使用的是Windows，请在/var/www/html/codeigniter/文件夹中创建一个上传文件夹。

输出应该如下所示。

    Your file was successfully uploaded!
    file_name: 6cedb4d846cade717196c96c155537fd.png
    file_type: image/png
    file_path: /var/www/html/ci/upload/
    full_path: /var/www/html/ci/upload/6cedb4d846cade717196c96c155537fd.png
    raw_name: 6cedb4d846cade717196c96c155537fd
    orig_name: download.png
    client_name: download.png
    file_ext: .png
    file_size: 4.76
    is_image: 1
    image_width: 126
    image_height: 126
    image_type: png
    image_size_str: width="126" height="126"

Answer 3

除了完全糟糕的配置外，还有两个可能的问题，我在这里看不到：

树中的一个文件夹是不可读的，即'uploads'和'products'目录都必须是可读的，当然也是可写的。
其他一些系统错误导致目录访问失败，例如：没有足够的磁盘空间或selinux权限。

Answer 4

您可以更改服务器上传目录777权限，这可以解决您的问题

Answer 5

尝试使用以下

更新.htaccess

SELECT  ( (SELECT COUNT(*) FROM scheme.student) + 
          (SELECT COUNT(*) FROM scheme.employer) 
         ) AS 'Column' ;
