我目前正在通过mysql在blueimp / jquery-file-upload脚本中插入标题和描述.我使用this教程让我在那里,但是,我需要添加另一个变量.该变量是当前登录用户的ID $_SESSION [“userid”]的会话,我想将其插入到我添加的名为uid的列中.通常很容易将另一列插入到插入中,但是这个脚本非常敏感,任何时候我都搞乱它,即使是最轻微的一点,我得到“SyntaxError：Unexpected token<”.任何帮助将不胜感激. /server/php/index.php

$options = array(
    'delete_type' => 'POST',
    'db_host' => 'localhost',
    'db_user' => 'fpform_fanuser',
    'db_pass' => '*****',
    'db_name' => 'fpform_fandata',
    'db_table' => 'files'
);

error_reporting(E_ALL | E_STRICT);
require('UploadHandler.php');

class CustomUploadHandler extends UploadHandler {

    protected function initialize() {
        $this->db = new mysqli(
            $this->options['db_host'],
            $this->options['db_user'],
            $this->options['db_pass'],
            $this->options['db_name']
        );
        parent::initialize();
        $this->db->close();
    }

    protected function handle_form_data($file, $index) {
        $file->title = @$_REQUEST['title'][$index];
        $file->description = @$_REQUEST['description'][$index];
    }

    protected function handle_file_upload($uploaded_file, $name, $size, $type, $error,
            $index = null, $content_range = null) {
        $file = parent::handle_file_upload(
            $uploaded_file, $name, $size, $type, $error, $index, $content_range
        );
        if (empty($file->error)) {
            $sql = 'INSERT INTO `'.$this->options['db_table']
                .'` (`name`, `size`, `type`, `title`, `description`)'
                .' VALUES (?, ?, ?, ?, ?)';
            $query = $this->db->prepare($sql);
            $query->bind_param(
                'sisss',
                $file->name,
                $file->size,
                $file->type,
                $file->title,
                $file->description,
            );
            $query->execute();
            $file->id = $this->db->insert_id;
        }
        return $file;
    }

    protected function set_additional_file_properties($file) {
        parent::set_additional_file_properties($file);
        if ($_SERVER['REQUEST_METHOD'] === 'GET') {
            $sql = 'SELECT `id`, `type`, `title`, `description` FROM `'
                .$this->options['db_table'].'` WHERE `name`=?';
            $query = $this->db->prepare($sql);
            $query->bind_param('s', $file->name);
            $query->execute();
            $query->bind_result(
                $id,
                $type,
                $title,
                $description
            );
            while ($query->fetch()) {
                $file->id = $id;
                $file->type = $type;
                $file->title = $title;
                $file->description = $description;
            }
        }
    }

    public function delete($print_response = true) {
        $response = parent::delete(false);
        foreach ($response as $name => $deleted) {
            if ($deleted) {
                $sql = 'DELETE FROM `'
                    .$this->options['db_table'].'` WHERE `name`=?';
                $query = $this->db->prepare($sql);
                $query->bind_param('s', $name);
                $query->execute();
            }
        } 
        return $this->generate_response($response, $print_response);
    }

}


$upload_handler = new CustomUploadHandler($options);

解决方法:

假设您要更改INSERT查询(您发布的代码中只有一个INSERT查询),这是您需要更改的内容：

if (empty($file->error)) {
    $sql = 'INSERT INTO `'.$this->options['db_table']
            .'` (`name`, `size`, `type`, `title`, `description`, `uid`)'
            .' VALUES (?, ?, ?, ?, ?, ?)';
    $query = $this->db->prepare($sql);
    $query->bind_param(
            'sisss',
            $file->name,
            $file->size,
            $file->type,
            $file->title,
            $file->description,
            $_SESSION['userid']
        );
    $query->execute();
    $file->id = $this->db->insert_id;
}
