Codeigniter AJAX文件上传不起作用

Question

我正在尝试将文件上传到应用程序文件夹所在的同一目录

-应用

-图片

-系统

-其他...

我正在尝试的代码是

$config = array(
        'upload_path' => "images",
        'allowed_types' => "*",
        'overwrite' => TRUE,
        'max_size' => "2048000", // Can be set to particular file size , here it is 2 MB(2048 Kb)
        'max_height' => "768",
        'max_width' => "1024",
    );
    if(isset($_FILES["image"]["name"])) {
        if (0 < $_FILES['image']['error']) {
            echo 'Error Occurred During Upload Of File ' . $_FILES['image']['error'];
        } else {
            $this->load->library('upload', $config);
            if(!$this->upload->do_upload('image')) { 
                echo $this->upload->display_errors();   //ALWAYS THIS LINE IS EXECUTING   
            }
            else {
                echo "FILE UPLOADED";
            }
        }
    } else {
        echo "Please Select A File";
    }

问题是，在最里面的 if 总是有注释的行正在执行，它说<p>The upload path does not appear to be valid.</p>。

当我尝试使用 is_dir 检查该目录是否存在时，它还说该目录存在，并且我尝试给它 777 文件权限，但我仍然遇到相同的错误。我也在网上尝试了大多数类似的答案，但都没有奏效。

请帮忙

试试这个：

$config = array(
        'upload_path' => "./images/",
        'allowed_types' => "*",
        'overwrite' => TRUE,
        'max_size' => "2048000",
        'max_height' => "768",
        'max_width' => "1024",
    );
