在Codeigniter中上载图像显示错误上载路径似乎无效

如何解决在Codeigniter中上载图像显示错误上载路径似乎无效

$config[\'upload_path\'] = site_path().\'photos/\';
$config[\'allowed_types\'] = \'gif|jpg|png|jpeg\';
$config[\'max_size\'] = \'2048\';
$this->load->library(\'upload\',$config);    
if ( ! $this->upload->do_upload())
{ 
    $this->data[\'alert\'] = $this->upload->display_errors();                     
    $this->load->view(\'profile/photo\',$this->data);
}   
else
{
    $upload_data = $this->upload->data();

    $filename = $upload_data[\'file_name\'];
    $width = $upload_data[\'image_width\'];
    $height = $upload_data[\'image_height\'];
    $config1 = array();
    $this->load->library(\'image_lib\');
    $config1[\'source_image\'] = site_path().\'photos/\'.$filename;


    $this->remove_existing_file($this->session->userdata(\'user_id\'));
    $this->Profile_model->savephoto(\'Edit\',$filename );
    redirect(\'/profile/photo\');
}

我收到此错误：上载路径似乎无效。

解决方法

发生此错误的原因只有几个：目录site_path().\'photos/\'不存在，请尝试运行is_dir()以确保它存在。该目录存在，但不可写。确保在目录上设置了适当的权限。尝试运行is_writable()以确保。您要使用的目录已存在，但尚未正确将其表示在Upload库中。尝试使用带有斜杠的绝对路径，类似于《用户指南》中的示例。除此之外，我没有想到的任何解释。这是用于验证路径的CI代码（属于Upload类的一部分）：

public function validate_upload_path()
{
    if ($this->upload_path == \'\')
    {
        $this->set_error(\'upload_no_filepath\');
        return FALSE;
    }

    if (function_exists(\'realpath\') AND @realpath($this->upload_path) !== FALSE)
    {
        $this->upload_path = str_replace(\"\\\\\",\"/\",realpath($this->upload_path));
    }

    // This is most likely the trigger for your error
    if ( ! @is_dir($this->upload_path))
    {
        $this->set_error(\'upload_no_filepath\');
        return FALSE;
    }

    if ( ! is_really_writable($this->upload_path))
    {
        $this->set_error(\'upload_not_writable\');
        return FALSE;
    }

    $this->upload_path = preg_replace(\"/(.+?)\\/*$/\",\"\\\\1/\",$this->upload_path);
    return TRUE;
}

更新：根据您的评论，尝试使用此方法，让我们看看在进行下一步调试之前会发生什么：

$config[\'upload_path\'] = \'./community/photos/\';

$config[\'upload_path\'] = \'./photos/\';
$config[\'allowed_types\'] = \'gif|jpg|jpeg|png\';
$config[\'max_size\'] = \'1000\';
$config[\'max_width\'] = \'1920\';
$config[\'max_height\'] = \'1280\';                     

$this->upload->initialize($config);

将此代码写在您的控制器块中这个问题很常见，我知道您在__construct（）块中编写了此代码，但是正确的方法是在调用上载代码的特定Controller中使用此代码。 , 这应该有帮助如果您需要在上传文件时自动创建以下目录：./assets/2016-07-27/，则必须扩展Upload库以自动创建目录（如果目录不存在）。代码：

<?php
defined(\'BASEPATH\') OR exit(\'No direct script access allowed\');

class MY_Upload extends CI_Upload {

    /**

     */
    public function validate_upload_path()
    {
        if ($this->upload_path === \'\')
        {
            $this->set_error(\'upload_no_filepath\',\'error\');
            return FALSE;
        }

        if (realpath($this->upload_path) !== FALSE)
        {
            $this->upload_path = str_replace(\'\\\\\',\'/\',realpath($this->upload_path));
        }

        if ( ! is_dir($this->upload_path))
        {
            // EDIT: make directory and try again
            if ( ! mkdir ($this->upload_path,0777,TRUE))
            {
                $this->set_error(\'upload_no_filepath\',\'error\');
                return FALSE;
            }
        }

        if ( ! is_really_writable($this->upload_path))
        {
            // EDIT: change directory mode
            if ( ! chmod($this->upload_path,0777))
            {
                $this->set_error(\'upload_not_writable\',\'error\');
                return FALSE;
            }
        }

        $this->upload_path = preg_replace(\'/(.+?)\\/*$/\',\'\\\\1/\',$this->upload_path);
        return TRUE;
    }
}

如何使用：只需创建application/libraries/MY_Upload.php并将上面的代码粘贴到其中即可。就这样！更多信息： GitHub Gist。我在Eharry.me上的博客文章注意：此扩展与CodeIgniter 3.x和2.x版本兼容。 , 如果您在Windows上，请尝试写入\“ c：\\\”，然后查看是否可行。还有site_path（）的输出是什么，例如echo site_path（）;。？在xammp上，我发现我需要写c：\\ xammp \\ htdocs \\ myproject \\ photos \\而不是仅使用\'\\ photos \\\'; , 您好在服务器上，您可以连接filezilla并右键单击文件夹并更改文件属性 , 检查您的.htaccess文件不阻止应用程序文件夹检查上传的是CHMOD 777 使用var_dump（is_dir（\'/ photos / \'））;看看您的目录是否存在！最后尝试一下：

    $config[\'upload_path\'] = \'photos/\';
    $config[\'allowed_types\'] = \'gif|jpg|jpeg|png\';
    $config[\'max_size\'] = \'1000\';
    $config[\'max_width\'] = \'1920\';
    $config[\'max_height\'] = \'1280\';                     

    $this->upload->initialize($config);

, 我认为问题可以通过使用解决

$config[\'upload_path\'] =\'./photos/\';

代替

$config[\'upload_path\'] = site_path().\'photos/\';

, 我知道这已经得到回答。即使是我也很难尝试上传文件。但就我而言，问题是我在/ var / www以外的文件夹中有CodeIgniter应用程序，而www文件夹中有索引页（主要是出于安全措施）。 uploads文件夹应位于包含index.php文件的/ var / www文件夹中。这就是我要做的。接下来是将777权限授予上载文件夹。 , 我在Windows上使用湿巾

$config[\'upload_path\'] = base_url().\'./resources/uploads/\';

根本不工作。

var_dump(is_dir($config[\'upload_path\'])); //return false
var_dump(is_writable($config[\'upload_path\']));  //return false

但是当我将其更改为

$config[\'upload_path\'] = \'./resources/uploads/\';   //works fine

它工作正常。所以我想在Windows上这不是权限问题，这是由base_url（）方法引起的，这有多奇怪。 , 在您的控制器中试用此代码

$config[\'upload_path\'] = \'images\'; //name of the uploading folder
$config[\'allowed_types\'] = \'jpeg|png|jpg\'; 
$config[\'file_name\'] = \'name_for_file\'; 

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

if (!$this->upload->do_upload())
 {
  echo $this->upload->display_errors();
  exit;
 }
else
 {
  $upload_data = $this->upload->data();
 }
