History: File Gallery User

            !File Galleries User
The file galleries section of Tiki is a download manager, you can create/edit file galleries which are collections of files, you can define with the permission system who can create file galleries, upload files and download files. Statistics are recorded for each download, rankings where defined for the top downloaded files, most visited file galleries and last uploaded files. Modules are also available to display last changed file galleries, last uploaded files, top downloaded files and top visited file galleries.

You can use file galleries to distribute free multimedia (mp3, avis, etc), to distribute software (versions, patches, releases), to add files that users can download from Wiki pages, articles or weblog posts, etc.

If you enable the file galleries section from the admin menu you' ll see a menu section in the main menu for file galleries. From the menu according to the permissions you have you will be able to list existing file galleries (where you can create a new gallery) or upload a file to a gallery. 

A file gallery is just a collection of files that can be downloaded or displayed, files are kept in the Tiki database or in a directory and the number of downloads for each file are registered. 

The List galleries option in the main menu will take you to the following screen: 

!! Listing File Galleries
{img src=http://tikiwiki.org/img/wiki_up/ListGalleries.jpg width=618 height=300 title='Old File Gallery listing' desc='Old File Gallery listing' alt='File Gallery listing'}

From this screen you can create a new gallery, edit existing galleries, remove existing galleries, upload a file to a gallery or list the contents (files) of an existing gallery. The options you see as a user depend on the permissions the admins have set for your groups. 

!!Creating file galleries 
To create a new file gallery click the  create new gallery  link and the following form will be displayed.

::{img type="fileId" fileId="984" desc="Tiki 12.x screenshot" alt="edit file gallery screenshot"}::

The same form is displayed to edit an existing gallery, you have to fill the gallery name and a description. 

You can make a gallery ===invisible=== to normal users by unchecking the  "Gallery is visible to non-admin users" checkbox. This can be used to set-up galleries that cannot be browsed but contain files that you will make available for downloading in your site using direct links to download the file. 

If you want to allow uploads to this gallery from other users check the "Gallery is unlocked" checkbox. If the checkbox is not checked then only the gallery owner (or admins) can upload files to the gallery. 

!! Uploading files 
To upload a file you use the following form:

{img src=http://tikiwiki.org/img/wiki_up/UploadFileSS.jpg}

In this form you enter a title and description for the file, the gallery where the file will be stored and then the file from your local disk to upload. If everything goes well you will see a message indicating that the file was uploaded.

{REMARKSBOX(type="warning",title="Bug in Tiki 5.0")}In Tiki 5.0, if you have specified that files are stored in the database rather than the file system, and if you can upload files but uploaded image files don't display correctly, try commenting out the last line of the file ''db/local.php''. This bug will be corrected in the next release. {REMARKSBOX}

!!! Access to the file in the gallery
Link to the file using Wiki syntax (substitue in fileId=x: x = the fileId number):
^
~np~
[tiki-download_file.php?fileId=x|file name that you want to display]
~/np~
^
Imbed an image 
^
~np~
{img src="tiki-download_file.php?fileId=x&thumbnail=y" link="tiki-download_file.php?fileId=x" alt="alternate file name"}
~/np~
^
Link to the file using html syntax 
^
<a href="tiki-download_file.php?fileId=x">file name </a>

!!! Batch uploads 
{FADE(label="(click to expand) Batch Upload Bug in 4.0 and 4.1")}
^
There are essentially three ways to upload multiple files using the file gallery (not image gallery) feature...

#Use the standard upload interface's "Add" button and add multiple files one at a time
#Upload a flattened (no nested directories) zip file and check the "Unzip zip files" checkbox
#Enable "Directory Batch Uploading" using Tiki's Admin Panel (tiki-admin.php) for the "File Galleries" feature (this may be visible only if checkbox __experimental__ is active, as in Tiki 9.1).

~~#c00:__As of 4.0 and 4.1...__ ~~

~~#c00:The "upload multiple files one-at-a-time" (#1 above) feature still works on CentOS, but not on Windows XP.~~

~~#c00:The "upload and unzip zip file" feature (#2 above) is broken for Tikis installed on CentOS (likely all Linux versions) and on Windows XP.~~

__The bug seems to be connected to a new file quota feature.__ A more detailed description can be found here:  [http://dev.tiki.org/tiki-view_tracker_item.php?trackerId=5&itemId=3033|Batch-Upload Bug Reported Here]

~~#c00:__This bug exists whether or not the user chooses to store the files in the MySQL database or in a system file directory.__~~

{FADE}

If you have the right permission to batch file uploads then you will be able to make a batch upload of files by uploading a .zip file to the gallery and checking the batch-upload checkbox (if you don't check it the zip is uploaded as a single file). 

Note that you must only give batch uploading permissions to admin since if users can make batch uploads the results can be unpredictable.
__Note__ that you can use the Batch uploads only when you don't use the database to store the content of the files!

Tiki does not unzip files in the subdirectories of the zip.

!!! Troubleshooting File Uploads
If an upload is failing, especially if it is a large file, try the steps found on ((Why File Uploads May Fail)).

!!Replace Files or Upload New Version
When browsing a file gallery, one of the actions available when you click on the {img src=img/icons/wrench.png} icon for a file (assuming you have permission), is to either {img src=img/icons/database_refresh.png} __Replace__ or {img src=img/icons/database_refresh.png} __Upload New Version__. Which one of these options appears depends on your settings for that gallery. This and the difference between the two options are explained below:
* __Replace:__ Means that the current file will be replaced with the new file you have chosen and the old file will be deleted. Within the gallery you are working on, click on the __Edit Gallery__ button (available if you have permission) and set ''Maximum number of archives for each file'' to __0__ to use this option.
* __Upload New Version:__ Means that the old file will be archived when the new file is uploaded. Within the gallery you are working on, click on the __Edit Gallery__ button (available if you have permission) and set ''Maximum number of archives for each file'' to the number of archives you wish to allow or to __-1__ to allow unlimited archives.
+ The archived files are also available under the {img src=img/icons/wrench.png} icon under the {img src=img/icons/disk_multiple.png} __Archives__ option.

Whether or not the ID number for the file stays the same or is incremented depends on the setting at __Admin Home -> File Galleries__. Check the ''Keep fileId for archives'' to maintain the same file ID. If unchecked, the new file will receive a new auto-incremented ID number.

!! Listing file galleries and downloading files 
Once you have some files uploaded to the gallery you can visit the gallery from the gallery listing menu and see the uploaded files:

{img src=http://tikiwiki.org/img/wiki_up/ListingFileGalleries.jpg}

From this screen you will see the gallery description and the files uploaded to this gallery (the number of files per page varies), you can order the list by any of the columns in the listing. Clicking the  get  link in the actions column will download the file to your local disk. 

!! Permissions 

The following permissions can be set for the file galleries section:

{img src=http://tikiwiki.org/img/wiki_up/FileGalULPermissions.jpg}

The tiki_p_admin_file_galleries is a master permission that automatically includes the other permissions.
