CKFinder 3 can't upload files

Question

I have a problem with the implementation of CKFinder 3. Everything works fine, except the uploading of files and images.

When I click on upload. I choose a file on my pc and then it gives me an error message called: Upload finished with errors. When I click on Details it shows: invalid file.

In my debug file it outputs this:

[02-Sep-2015 16:35:27 Europe/Berlin] PHP Notice:  Undefined index: dirname in ckfinder/core/connector/php/vendor/cksource/ckfinder/src/CKSource/CKFinder/Filesystem/File/UploadedFile.php on line 70

Can someone please help me with this?

This is my config.php code of CKFinder:

Do you host CKFinder connector on IIS server? There was an issue with accessing the temporary directory on this configuration. — zaak, Sep 02 '15 at 15:22
I'm using XAMPP locally, do I have to change something. I don't know much about IIS Servers etc. — EddieAjax, Sep 03 '15 at 08:14
I've just checked a fresh installation of XAMPP 5.6.12 on Windows 7 and I couldn't reproduce this issue, everything seems to work fine. The only thing I had to do was enabling the `Fileinfo` extension (http://docs.cksource.com/ckfinder3-php/quickstart.html#quickstart_beforebegin_fileinfo). What version of XAMPP and what version of Windows do you use? — zaak, Sep 03 '15 at 15:07
I have XAMPP 5.5.19 running on my Macbook Pro with Yosemite. I did the Fileinfo extension already, but It still didn't work. — EddieAjax, Sep 04 '15 at 08:43

I was able to reproduce this issue on OSX. There's a problem with access to the preconfigured temporary directory in this version of XAMPP. This can be altered with sys_temp_dir directive in php.ini, but can be also configured in the new version of CKFinder.

Please try following:

Download the pre-release 3.1 version of CKFinder from this link.
Open CKFinder connector config (config.php) and look for tempDirectory option on the bottom of the file.
Replace sys_get_temp_dir() with your XAMPP temp directory path. For me it was /Applications/XAMPP/xamppfiles/temp/.

So instead:

$config['tempDirectory'] = sys_get_temp_dir();

there should be:

$config['tempDirectory'] = '/Applications/XAMPP/xamppfiles/temp/';

Configure other required CKFinder options, like authentication. Uploads should work fine now.

Another solution:

Instead of changing this on application level like described above you may also set a global sys_temp_dir directive in php.ini. To do that add a following line to /Applications/XAMPP/xamppfiles/etc/php.ini:

sys_temp_dir = "/Applications/XAMPP/xamppfiles/temp/"

Then restart Apache in XAMPP. After that the temporary directory location can be fetched with sys_get_temp_dir(), so there's no need to change tempDirectory option in CKFinder config.

Thanks a lot! This solved the problem for me! I do have one question though: If you go online, do you have to change the tempDirectory back to sys_get_temp_dir()? — EddieAjax, Sep 06 '15 at 19:18
It depends on what you mean by _going online_. If it's about making your machine accessible from the net, then no - the `tempDirectory` option should stay the same. If it's about deploying your app to a remote server, then yes - you will most probably need to set it back to `sys_get_temp_dir()`. I've edited my answer and added _Another solution_ describing how to set `sys_temp_dir` globally in `php.ini`. In this case you can keep using `sys_get_temp_dir()`. — zaak, Sep 07 '15 at 06:56
