Upload error - The file could not be written to disk

[eluser]PermanaJ[/eluser]
Im trying to upload image, but I get this error message

"The file could not be written to disk"

Dont want to get confuse with file permission, i set the folder 777. What could be the reason that error happen ? I use this setting :

Code:

...

$upload_cfg['upload_path'] ='./images/photos/';
$upload_cfg['allowed_types'] = 'gif|jpg|png';
$upload_cfg['max_size']    = '200';
$upload_cfg['max_width']  = '200';
$upload_cfg['max_height']  = '200';
$upload_cfg['encrypt_name'] = true;

...

That error is actually a PHP error, not anything to do with CodeIgniter as such. There error is [url="http://uk3.php.net/features.file-upload.errors"]UPLOAD_ERR_CANT_WRITE[/url].

The obvious reason for it not working is that the permissions or not set correctly, so I'd suggest you check the directory really is writeable by trying to create a blank file in there with PHP, or using is_really_writable().

Another reason might be your allowed Web quota. If you're nearing the limit, you may not be able to write to the disk.

I think no problem with the web quota, But I will try using the function that you suggest. Thanks for the reply

btw, when i try this code :

Code:

$isWriteable = is_really_writable('./images/photos/');
if($isWriteable){
    echo 'yes it is really writeable';
}else{
    echo 'no, it is not really writeable';
}

it result "yes it is really writeable", i haven't try creating blank file gonna try it in minutes

Hi,

I have the same problem here,.. is there anyway to solve this problem?

Thanks

@omar_yoi

i was posted this a year ago. I forgot how to solve this problem :| because when I trial and error it's just working. try using without . (dot) in file path ..

[eluser]omar_yoi[/eluser]
I am using this code to explain the path to the images

Code:

$this->gallery_path = realpath(APPPATH . '../img');

I have tried to removed one dot (.) or both, however the following error message appears:
The upload destination folder does not appear to be writable.

otherwise if I did not remove it at all, the following message appears:
The file could not be written to disk.

I have no idea what is going on since I did not change the code at all, and I did not do any changes on the web server (FreeBSD Platform) as well.

Any other suggestion to solve the problem?

Thank you in advance.

Ok, my problem solved.

I'm running on FreeBSD, my /var directory is already hit 100% capacity (full), so since the db was located under /var/db/ the database refused to write the file.

In my case, I moved all the directories which contain big size of data to /usr and made a symlink from /var to /usr. Then the size of /var directories was reduced 60% capacity, so that the database could continue to write the file.

Thanks to PermanaJ and TheFuzzy0ne for giving me the ideas of what causing the problem.
