接受用户上传最佳做法！ [英] accepting user uploads best practices!
问题描述
我试图在php中使用zend框架添加多页面表单，用户可以在其中列出项目到我的站点。在第一页上，他们输入有关该项目的详细信息（然后存储在会话中），第二页他们可以上传图像，然后第三页他们可以确认列表。如果他们确认，则添加列表。
Im trying to add a multi page form, in php with zend framework, where users can list an item to my site. On the first page they enter details about the item(which is then stored in session), page two they can upload images, and then page three they can confirm the listing. If they confirm then the listing is added.
在允许用户上传图片方面，实现此目的的最佳方法是什么？我将使用SWFUpload或uploadify，但是我应该将图像直接添加到数据库中，如果是这样，在哪个列表ID下？在用户点击确认之前，我不会创建列表ID。那么最佳做法是什么？我应该将它们存储在以会话命名的临时文件夹中吗？存储在数据库中的临时名称如地址+会话或什么？
What is the best way to achieve this with regards to allowing users to upload images? I am going to either use SWFUpload or uploadify, but should i add the images straight to the database and if so under which listing id? I dont create the listing id until the user clicks confirm. So whats the best practises? should i store them in a temp folder named after session? store in database under temp name like address + session or what?
编辑：嘿抱歉也许我没有表达自己非常清楚。我不是在寻找上传文件的方法。在我知道用户是否确实要确认列表之前，我要问的是如何最好地存储它们。我应该将它们存储在临时文件夹中，然后在用户确认列表时处理它们，然后编写一个删除一小时前创建的文件夹的自动脚本。或者我应该将它们存储在临时表中的数据库中的某种由会话和列表属性组成的密钥下？基本上我问的是，在你确认并创建它之前，ebay对你上传的图片做了什么。
edit: Hey sorry maybe I have not expressed myself very clearly. I am not looking for a way to upload files. What I am asking is how best to store them before I know whether the user is actually going to confirm the listing. Should i store them in a temp folder and then process them when the user confirms listing and then write an automatic script that deletes folder created over an hour ago. Or should i store them in the database in a temp table under some kind of key made up of session and a listing attribute? Basically I am asking what does ebay do to the images that you upload when adding a listing but before you have confirmed and created it.
非常感谢你的帮助！
