PHP hoses form uploads?!

frigidman

I have been sitting here for the past two hours trying to make PHP "NOT" corrupt any sort of file upload through a form.

Enctype is set correctly, it saves a file on the server /tmp location, and it even copies the file from there to the new location to keep it past script execution.

The problem is... its getting seriously corrupt somewhere in there.

Simple script:
Upload an image, either .gif or .jpg.
copy() the tmp file to new location.

If I try to run a getimagesize() function on it, it returns nothing. If I try to ownload the file it has on the server, it wont open in anything I have. The original file on my machine will open in any graphic program I have. So the original is ok... but the one getting saved on the server is hosed beyond recognition.

Anyone have any idea why PHP would be doing this?

Server:
Linux YDL2.1
Apache
PHP4+

open the uploaded image file in a hex editor along with the original image and see if you can find a pattern to the corruption.

i'm using php to upload image files and it works fine with me.

Its adding this to the top of the file:

Content-Type: image/jpeg

Why on earth is it doing that ?
Why would this work for some others, but not working for me right now?

I'm getting mighty upset. No other scripting language ever corrupted file uploads with forms... its BASIC. Grrrrrrrrrrrr....

Forgot to mention, it does this whether uploading an image file from Mac IE or PC IE... either one, they both get corrupted at the server by PHP.

Is there some setting I am missing? There are only 3 in the php.ini file, which are to allow uploads, temp upload dir, and max size. I have the max size at 8M... more then enough for a 770byte gif or jpg.

Ok... it appears the file isnt the only isolated place where its screwing up. It appears to me that PHp is fully screwing up the POST data from a multipart/form-data type form.

All text fields are getting extra "newlines" added to the data in them, and it does it to all values from checkboxes, popups, and radios. Everything is getting bad mojo.

GUH?!
HELP! AAAAAAAAA....

Hey Randall, could you give us a bit more info? What server set up, what version PHP and all.

Like Brandon, I made a file upload without any problems whatsoever.

Thought I said that... must be in another post.

Specs:
YDL Linux 2.1
G3 cpu
PHP 4.0.4pl1
Apache/1.3.14 (Unix) (Linux)
MySQL 3.23.32

I am looking into now trying to 'upgrade' the php to the 4.0.6 version I just now found on php.net. I would have thought the brand new YDL distribution I got last week would have had a MORE UP TO DATE VERSION IN IT! grumble... I am believing its just the php version 4.0.4pl1 that is seriously buggy.

I would have it upgraded by now, if I knew what modules to include during configure. Lack of docs in the install archive is leaving me hanging...

I finally managed to hack together PHP 4.0.6 ... and the form upload now works. As does all the other fields in a multipart/form-data type form.

Evil... they shouldn't even be possing that 4.0.4pl1 around with system installs like that!!!
