CodeIgniter + uploadify 在 IE 下会话丢失问题的解决方案

阅读更多关于 CodeIgniter + uploadify 在 IE 下会话丢失问题的解决方案

最近需要学习并用 CodeIgniter框架对一个项目进行二次开发，由于之前一直都是使用Symfony做项目，所以再换到CodeIgniter项目上还是比较顺畅的。不过相比较之下，感觉CodeIgniter比Symfony要轻量很多，当然这不是本文的讨论点。接下来会将我遇到的问题描述出来并给出最终的解决方案，希望能帮助到和我遇到同样问题的朋友。在项目开发中需要用到文件上传的功能，这边前端是使用 uploadify来实现文件上传功能的。在firefox完成这个功能的实现，测试并没有问题一切正常。可是在 IE 下的时候，头疼的问题就来了。文件上传成功之后，用户会话却丢失了。导致用户需再次登录，并且上一步的后续操作也没有执行（因为有权限验证，会话丢失之后验证不通过造成的）。网上搜索的结果大致都是firefox, chrome 下使用uploadify时使用了flash插件，flash中有个bug就是自身会创建一个session，这样就导致与web本身的session不一致，导致服务端权限验证失败的问题。可是我在firefox和chrome下是可以正常使用并没有出错，出错的反而是在 IE。后来经过一番分析找到原因了，首先CodeIgniter框架中session使用的不是php原生的session机制而是自己的一套东西，CodeIgniter会把session保存到Cookie中

Uploadify: show error message from HTTP response

阅读更多关于 Uploadify: show error message from HTTP response

If the server returns an error (HTTP response code != 200) when uploading a file with Uploadify, the uploaded file gets a red background and a message is show like this: file.jpg (52.78KB) - HTTP Error indicating that there was a HTTP Error. But that's not very useful to the the user. How can I make it show a more detailed error message? Like: 'Not a valid image' or 'Quota full'? I was thinking of passing those messages in the HTTP response body, but Uploadify doesn't pick them up. Is there a known way to pass error messages back to Uploadify? Take a look at these two posts in the uploadify

上传大文件的解决方案

阅读更多关于上传大文件的解决方案

需求：项目要支持大文件上传功能，经过讨论，初步将文件上传大小控制在500M内，因此自己需要在项目中进行文件上传部分的调整和配置，自己将大小都以501M来进行限制。第一步：前端修改由于项目使用的是BJUI前端框架，并没有使用框架本身的文件上传控件，而使用的基于jQuery的Uploadify文件上传组件，在项目使用的jslib项目中找到了BJUI框架集成jQuery Uploadify的部分，这部分代码封装在bjui-all.js文件中，在bjui-all.js文件中的全局变量定义中有以下部分代码，这就是定义的有关于上传的Uploadify控件的重要变量： upload:{uploadLimit:5,fileSizeLimit:31744,removeTimeout:0.8} 以上三个变量代表的含义是： uploadLimit ：表示上传文件个数的限制，5表示文件上传个数限制是5个 fileSizeLimit ：表示上传文件大小的限制，31744单位是KB，也就是表示31M removeTimeout ：表示移除文件的时间限制继续查找使用到这些变量的地方，看到了文件大小超出限制等了解了BJUI前端框架对于上传大文件的限制，可以这样使用，增大文件上传大小和数量，可以按照如下进行修改，我们在bjui-all
