File Upload, and MD5/SHA1 Errors.

[DrThodt]

Hello, here is my problem.

On certain files when I upload them they show up as 0size no type or any information associated with it. I thought maybe the file was to big for the default filesize php allows for uploads. I tried 2MB, 5MB, 15MB, 25MB, 50MB, 85MB files. this wasn't the case. As some files that were as large or larger worked fine. My question is, is this a bug in php or is itpossibly related to apache not knowing the mimetype? It mostly occurs with rar files and exe's.

Also when I upload a file and it succeeds I perform an MD5/SHA1 check, though oddly enough the MD5/SHA1 that is outputted is completely different from the program I originally created the hash with. Am I doing this wrong?

md5($FILES['file']['name'])

or do I have to use some specific function to read the file correctly for md5/sha1 or even open it and read its contents?

Thanks in advance.

first off $FILES, shoud be $FILES
and i am guessing you want to get the md5/sha hash of the file contents, not just the name, so you would want to to
md5_file($FILES['file']['tmp_name'];

ok so I did...

print "MD5: ".md5($FILES['file']['tmp_name']);
print "SHA1: ".sha1($FILES['file']['tmp_name']);

the original hashes were...

FILE: scary_terri.jpg
MD5: 76f2bb38ff6c2f46be3670a9fded699e
SHA1: 75fd1a389625dcb058bfab1e8f01d4bf9567770b

php md5() and sha1() produced...

MD5: e2bda290bc702a50d69bf777cd6e61a9
SHA1: 2bfe40bfc4feaa5c886857608a7ef229806c29f6

EDIT: So MD5 and SHA1 still dont work, and I can't upload all rar files etc.

[drew010]

yes i know, that is just taking the md5 and sha1 of the file name.

use
md5_file()
sha1_file()

[DrThodt]

Wow, thank you very much! Now to go and figure out this other error ^_

[drew010]

yeah im not sure why files of that type wont upload. php shouldnt really care what type it is, its all up to you to handle what to do with them.

if you continue having trouble, post the code and ill see if there are any fixes.

I solved it, I had to edit...

post_max_size

and

upload_max_filesize

though I am getting this...

Warning: md5_file(): Unable to open file in c:\program files\apache group\apache\htdocs\submit.php on line 6
MD5:
Warning: sha1_file(): Unable to open file in c:\program files\apache group\apache\htdocs\submit.php on line 7
SHA1:

Code:

<?php
if (move_uploaded_file($FILES['file']['tmp_name'], $FILES['file']['name'])) {
print "MD5: ".md5_file($FILES['file']['tmp_name']);
print "SHA1: ".sha1_file($FILES['file']['tmp_name']);
}
?>

I even tried...

<?php
if (move_uploaded_file($FILES['file']['tmp_name'], $FILES['file']['name'])) {
print "MD5: ".md5_file($FILES['file']['name']);
print "SHA1: ".sha1_file($FILES['file']['name']);
}
?>

This is confusing as I just had it working a few minutes beforehand on another file.

[drew010]

you will either have to do the md5_file and sha1_file calls before move_uploaded_file or you would need to change the variable inside from $_FILES['file']['tmp_name'] to the new filename they get. when you do move_uploaded_file the pointer to tmp_name gets outdated.

would $_FILES['file']['name'] work if I'm uploading into teh directory the script is executing from?

[drew010]

yes, i think that would work.

Ah finally, everything works
