Uploadify3.1上传5M以上文件显示成功,实际没上传成功
PHP Uploadify3.1上传4M多的可以上传成功,上传大点的,进度条和提示都显示成功,但实际文件没上传成功,调试环境IIS6
,可以确认路径没问题,操作应该也没问题,是不是uploadify本身不能上传大文件?还有没有其他好的上传大文件的PHP插件介绍。
JS代码如下

------解决方案--------------------
不是程序就是环境限制了上传大小
------解决方案--------------------
探讨

大哥可否说详细点 这个上传不上分块上传的吗?
如果不上分块的 估计肯定是上传不了的

------解决方案--------------------
if (!empty($_FILES)) {
if($_FILES['Filedata']['error'] != 0) die('错误号:' . $_FILES['Filedata']['error']);
$tempFile = $_FILES['Filedata']['tmp_name'];
....
------解决方案--------------------
php.ini设置max_post_size大于等于5m就行了
