文件上传导致文件大小为0，错误代码为0 [英] File upload results in file size 0 and error code 0
问题描述
我正在尝试将图像上传到php脚本.我有一个非持久性错误，导致某些上载的图像的文件大小为0.我试图将_FILES数组打印到我的日志文件中，并且显示错误代码为0，应该可以
I'm trying to upload an image to a php script. I have a, non-persistent, bug that results in some of the images uploaded has a file size of 0. I have tried to print the _FILES array to my log file, and it shows the error code being 0, which should be ok.
这些行:
foreach($_FILES['image_file'] as $key => $val){
error_log(date('j/n/o H:i:s')." ". $key ." => ".$val. "\n", 3,$log_path);
}
在日志文件中给我这些信息
Give me these in the log file:
- 2012年3月10日12:12:54名称=> 59175248636.jpg
- 2012年3月10日12:12:54类型=>图片/jpeg
- 2012年3月10日12:12:54 tmp_name => C:\ WINDOWS \ Temp \ php411F.tmp
- 2012年3月10日12:12:54错误=> 0
- 2012年3月10日12:12:54大小=> 0
可以从日志文件中读取该脚本，该脚本在Windows机器上运行，据我所知.我已经在php.ini中将post_max_size更改为10M，并将upload_max_size更改为10M.
As can be read from the log file, this script runs on a Windows machine, of which I have limited knowledge. I have already changed the post_max_size to 10M, as well as upload_max_size to 10M in the php.ini.
我对此问题感到震惊.当我在自己的设备上进行测试时，它可以正常工作，但是由于某些原因，当我的测试人员尝试该程序时，它会失败.
I am flabbergasted about this issue. When I test from my own devices, it works fine, but for some reason, when my testers try it out, it fails.
推荐答案
编辑-尝试以下操作:
我认为您可能需要将$ _FILES ['file']更改为$ _FILES ['image_file']才能使用您的设置.为了便于阅读，我将其保留如下.
I think you may need to change $_FILES['file'] to $_FILES['image_file'] to work with your setup. I have left it as below for ease of reading...
if ($_FILES['file']['error'] === UPLOAD_ERR_OK && $_FILES['file']['size'] > 0){
... upload was successful ...
}elseif($_FILES['file']['error'] === UPLOAD_ERR_OK && $_FILES['file']['size'] == 0){
die("Upload failed, random upload issue... please try again);
// change this error to something more useful... (leave this error in for testing)
}else {
die("Upload failed with error code " . $_FILES['file']['error']);
}
这不能解决随机文件大小的问题，但可以使您的代码/过程继续进行.将其视为上传失败，并告诉用户重试...
This doesn't solve the random filesize issue, but it will allow your code / process to continue. Treat it as a failed upload and tell the user to try again...
