Question

我在我的网站上使用“Blueimp Jquery file upload plugin”，并且我允许用户在我的服务器上上传文件。我在HostGator上托管了我的网站。问题是用户无法上传文件大小超过64MB /文件，搜索后我发现HostGator已将上传文件的限制设置为64MB /文件，最大限度地在“php.ini”文件中，我不能改变这个大小限制。

但实际上我可以直接通过FTP上传任意大小的文件而没有任何限制。

所以，我在询问是否有可以使用的解决方法来避免此HostGator限制，或者如果有办法允许用户通过FTP将文件直接上传到服务器，则抛出这个jquery插件“web应用程序”。

Answer 1

你绝对可以更改hostgator的最大文件大小设置，因为我已经多次这样做了。

在您选择的目录中，创建.htaccess文件。在此文件中包含php覆盖设置。

php_value upload_max_filesize 200M
php_value post_max_size 200M

除非最近几个月发生了变化，否则这种解决方法一直对我有用。

Answer 2

jupload可以通过ftp上传

http://jupload.sourceforge.net/

这是一个很好的解决方案imo。虽然并非所有用户都启用了java，但您可以使您的html页面优雅地降级为http上传，在这种情况下，唯一丢失的用户是那些想要上传大文件的用户。

或切换webhosts--另一种简单有效的解决方案。

Answer 3

你 CAN 使用带有＆＃34; Blueimp Jquery文件上传插件的＃＆＃34;但它需要一些PHP编码。不要破解UploadHandler类（file-uploads / server / php / UploadHandler.php），而是应该扩展它并根据需要覆盖这些函数。

使用以下内容替换file-uploads / server / php / index.php的内容：

require('UploadHandler.php');

/*
 *  custom class for uploading files, simply extends the UploadHander class
 */
class CustomUploadHandler extends UploadHandler {


    /*
     * rewreite the handle_file_upload() function to use FTP to send the files to the FTP server
     */
    protected function handle_file_upload($uploaded_file, $name, $size, $type, $error, $index = null, $content_range = null) {
        $file = new stdClass();
        $file->name = $this->get_file_name($uploaded_file, $name, $size, $type, $error,
            $index, $content_range);
        $file->size = $this->fix_integer_overflow((int)$size);
        $file->type = $type;
        if ($this->validate($uploaded_file, $file, $error, $index)) {
            $this->handle_form_data($file, $index);
            $upload_dir = $this->get_upload_path();
            if (!is_dir($upload_dir)) {
                mkdir($upload_dir, $this->options['mkdir_mode'], true);
            }
            $file_path = $this->get_upload_path($file->name);
            $append_file = $content_range && is_file($file_path) &&
                $file->size > $this->get_file_size($file_path);
            if ($uploaded_file && is_uploaded_file($uploaded_file)) {
                // multipart/formdata uploads (POST method uploads)
                if ($append_file) {
                    file_put_contents(
                        $file_path,
                        fopen($uploaded_file, 'r'),
                        FILE_APPEND
                    );
                } else {
                    move_uploaded_file($uploaded_file, $file_path);
                }
            } else {
                // Non-multipart uploads (PUT method support)
                file_put_contents(
                    $file_path,
                    fopen('php://input', 'r'),
                    $append_file ? FILE_APPEND : 0
                );
            }
            $file_size = $this->get_file_size($file_path, $append_file);
            if ($file_size === $file->size) {
                $file->url = $this->get_download_url($file->name);
                if ($this->is_valid_image_file($file_path)) {
                    $this->handle_image_file($file_path, $file);
                }
            } else {
                $file->size = $file_size;
                if (!$content_range && $this->options['discard_aborted_uploads']) {
                    unlink($file_path);
                    $file->error = $this->get_error_message('abort');
                }
            }
            $this->set_additional_file_properties($file);
        }

        /* 
         * now send it to the FTPserver
         */
        $source_file = $file_path; // the path of the file to upload
        $destination_file = '/your/path/' . $file->name; // the file path to upload to (must have trailing / in the path before the $file->name is appended)

        $ftp_error = $this->ftp_upload($source_file, $destination_file);

        if ($ftp_error != '') {
          $file->error = $ftp_error;
        }

        return $file;
    }


    /*
     * new function for uploading using FTP
     */
    protected function ftp_upload($source_file, $destination_file) {

        $ftp_server = 'YOUR FTP HOST NAME';
        $ftp_user_name = 'YOUR USER NAME';
        $ftp_user_pass = 'YOUR PASSWORD';
        $port_number = YOUR FTP PORT NUMBER;

        $error = '';

        // set up basic connection
        $conn_id = ftp_connect($ftp_server, $port_number); 
        if (!$conn_id) {
            $error = "FTP connection has failed! Connection attempt was blocked." ;
            return $error;
        }

        // login with username and password
        $login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass); 

        // check connection
        if (!$login_result) { 
            $error = "FTP connection has failed! ";
            $error .= "Could not log into fpt://$ftp_server for user $ftp_user_name"; 
            return $error;
        }

        // upload the file
        $upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY); 

        // check upload status
        if (!$upload) { 
            $error = "FTP upload has failed!";
        } else {
            $error =  "Uploaded $source_file to $ftp_server as $destination_file";
        }

        // close the FTP stream 
        ftp_close($conn_id); 

        return $error;
    }

}

// options to pass to the upload handler object
$options = [
   // ANY OPTIONS, SUCH AS FILE UPLOAD LOCATION
   'upload_url' => 'fpt://YOUR-FTP-SERVER-NAME/files/',
];

// finally, instantiate the new class   
$upload_handler = new CustomUploadHandler($options);

请注意，这只是在将文件上传到上传服务器后通过ftp将文件复制到ftp服务器。这意味着您将拥有同一文件的两个副本。您可以删除最初上传的文件而无需额外的工作，但请确保先完成ftp操作。

您需要 AND ，您需要Ohgodwhy所描述的.htaccess apache设置

使用“Jquery文件上传插件”将文件直接上传到FTP服务器
