.TMP File issue?

Mediawiki Version: latest, PHP version Latest mySQL latest --- When Users try to upload images onto the wiki, they get a error that states "Cannot find C:\WINDOWS\TEMP\PHP"X" Whereas X indicates a letter (currently PHPc.tmp) I've disabled Imagemagic(sp?) and I am still getting an error. Can I remote host the images and what tag would I use to embed it?

Potential bug in FSRepo.php causes image uploads to fail on Windows server: Internal error - Could not create directory

 * MediaWiki version: 1.15.0
 * PHP version: 5.1.6 (apache2handler)
 * MySQL version: 5.0.45-community-nt
 * URL: index.php?title=Special:Upload (on a private wiki)

I've been trying to debug file uploads on my Windows server. After going to Special:Upload and uploading a jpg (an allowed format) it would die with something like this: Internal error

Could not create directory "public/a/a5".

It would also generate a PHP error: Warning: mkdir [function.mkdir]: No such file or directory in \includes\GlobalFunctions.php on line 2012

I did some debugging and mkdir is called by wfMkdirParents which in this case is called by publishBatch in FSRepo.php line 298: if ( !is_dir( $dstDir ) && !wfMkdirParents( $dstDir ) ) {

I think the $dstDir path is not a valid one on the Windows server because the path is constructed manually in publishBatch using forward slashes ("/"), so what gets eventually passed to mkdir is something that looks like this: C:\my\path\htdocs\mediawiki/images/a/a5

I added this statement to GlobalFunctions.php at line 2011 to fix the path: $dir = str_replace('/', '\\', $dir);

So $dir was changed to something like this: C:\my\path\htdocs\mediawiki\images\a\a5

This solved my problem and I was able to upload files. Perhaps FSRepo.php needs to be more sensitive to servers that require a backslash as a path separator? Or is there a better way to fix this problem?

I am not running PHP in safe_mode and I have left $wgHashedUploadDirectory defaulted to true.

cheers, Dave

Change File Upload Destination to different partition on server

 * MediaWiki version: 1.14.0
 * PHP version: 5.2.9-1
 * MySQL version: 5.1.32
 * URL: private

I have a server that I set up MediaWiki on. Unfortunately it was installed in the C: partition that doesn't have much extra space. So, I'd like to point the file upload path to another partition (D:) on the server. I would appreciate any help you can provide. Thank you.

(RESOLVED) Unable to create public/x/x errors...

 * MediaWiki version: 1.15.1
 * PHP version: 5.2.10
 * MySQL version: 5.0.81
 * URL: http://www.aesedra.com/wiki/

I recently upgraded to wiki 1.15.1 and it went well. The thing is, when I try to upload a picture, I get ''Could not create directory "public/3/3b". . In my logs, I get Wed Jul 22 01:21:25 2009] [error] PHP Warning: mkdir [function.mkdir]: Permission denied in /home/aesedra/public_html/wiki/includes/GlobalFunctions.php on line 2012''

The images directory has been set to 777, LocalSettings.php has $wgEnableUploads = true; ''$wgUploadPath = "$wgScriptPath/images"; $wgUploadDirectory = "$IP/images"; ''

mkdir is not a disallowed function on my site. It works.

The funny thing is, if I go to any page that has a picture, I get a php warning (but the picture still shows) [Wed Jul 22 01:17:49 2009] [error] PHP Warning: imagejpeg [function.imagejpeg]: Unable to open '/home/aesedra/public_html/wiki/images/thumb/4/41/Wikibelantine.jpg/85px-Wikibelantine.jpg' for writing: Permission denied in /home/aesedra/public_html/wiki/includes/media/Bitmap.php on line 236

I'm not sure what's going on here, and thanks in advance for your help.

Edit: the uploads now work, but now I'm getting a zillion PHP warnings and black thumbnails.

 * Same problem here:


 * MediaWiki version: 1.15.1
 * PHP: 5.2.4-2ubuntu5.6 (apache2handler)
 * MySQL: 5.0.51a-3ubuntu5.4


 * Is this a software bug or how can I fix it?
 * --JuergenL 12:43, 22 July 2009 (UTC)


 * OK, it seems there is a disconnect between what actually is in /images/ and what the database thinks there is. I had to delete all my pictures and re-upload them. That fixed the black thumbnails/permission denied errors. Thi all occurred because I upgraded to 1.15.1 from 1.14 something. The upgrade script bombed out saying no connection to the database could be found despite the settings being right. So, I had to reinstall the Wiki using the upgrade/reinstall guide found here. This is when everything started to go south. Somehow, the database wasn't upgraded correctly or something and what exists in my /images/ folder didn't correlate with what the db said. This is my guess. Anyhow, it's all fixed, but I'll be wary of upgrading anything from here on. Peter Greenwell 14:01, 22 July 2009 (UTC)

Change Upload Directory in MediaWiki 1.14

 * MediaWiki version: 1.14
 * PHP version: 5
 * MySQL version:
 * URL: NA

I have been creating a wiki on my localhost, it is a dell laptop,i have a dual boot, and have it on both the linux and windows sides, i have been creating it as a test for my company, i have found a variable in LocalSettings.php "$wgUploadDirectory" that can change the upload directory from the images directory in mediawiki, to another directory outside the mediawiki directory, namely a shared directory for the business, or as a test, MyDocuments directory in my C: drive. The documentation i've found is good, but not specific as to how you point it to a local directory outside of the mediawiki directory, i tried adding this line

$wgUploadDirectory = "C:\Documents and Settings\IDT user\My Documents"

and i got this error message: "Parse error: parse error in C:\xampp\htdocs\mediawiki\LocalSettings.php on line 133" which is the line i added. anyhelp you can as to what i need to add or what variable value i can put, to allow this to work would be appreciated.
