PHP jQuery的阿贾克斯（）文件上传服务器端的理解 [英] PHP jQuery .ajax() file upload server side understanding

问题描述

我有一个HTML形成previously仅用于为用户文本属性，这是所有使用AJAX通过URL来调用PHP控制器的功能，通过数据库和服务器端调用（删节版），以刷新页面内容

I have an HTML form that previously was only used for text attributes for users, that was all using AJAX to call a PHP controller functions via URLs to refresh page content via database and server-side calls (abridged version)

 <input type="text" id="firstname" name="FIRSTNAME"/>
 <input type="text" id="lastname" name="LASTNAME"/>
 <input name="Submit"type="submit" value="Submit" />

这创建用户的形式现在需要将文件上传机制，用户图像

This "create user" form now needs to incorporate a file uploading mechanism, for user images

 <input type="file" name="userImage" />

问题是，窗体被通过 .serialize 提交的阿贾克斯 #create表单提交

The problem is that the form is being submitted via .serialize in the .ajax #create form submit

        $.ajax({
            url: 'controller.php?command=create',
            type: 'POST',
            data: $( form ).serialize(),

创建URL调用PHP控制器回声$ dmv-＆GT;创建（）; ，这是模型公共函数来创建（）{/ /执行数据库插入并执行

我已阅读，连载没有意义的文件，这是事实，但我也想尝试找出如何更新我现有的形式将文件上传功能，它

I have read that serialize does not make sense for files, which is true, but I also want to try to figure out how to update my existing form to incorporate file upload functionality to it

我试图理解 jquery.form.js 插件（的 http://malsup.com/jquery/form/#file-upload ），但不知道如何将其结合在一起。

I have tried to understand the jquery.form.js plugin ( http://malsup.com/jquery/form/#file-upload ) but cannot understand how to tie it all together.

我相信什么，我需要做的是有一个单独的逻辑文件上传执行，再配合背部与文件名原来的逻辑，这是文件存储与记录，而不是在存储于数据库中的唯一的映像名称BLOB图像存储。

I believe what I need to do is have the file upload execute as a separate logic, then tie back with the original logic for file name , this is file storage with the unique image name stored in the database under the record, not BLOB image storage.

让我知道如果我能提供任何进一步的信息，并且由于可以给予任何帮助。

Let me know if I can provide any further info, and thanks to any help that can be given.
