1. Action

1.1. upload

• Form for file upload to a page or into global space
• Invoke: {{upload [global=1] [maxsize=200] [hide_description=1]}}
• Parameters:
  • global — this option allows uploaded files to be globally available for all users
  • maxsize — forcedly limits maximum size (must be less than in config)
  • hide_description — not to show text field "description", there remains only field for the file

Note : Please keep in mind that files might be rejected based on other criteria, for example lack of disk space, because the file is larger than the maximum allowed file size or because your web-host does not allow particular files.

If you’d like to allow larger files, you’ll need to edit the PHP configuration file (php.ini) and add or set the following lines in php.ini (the example allows files up to 32 Mb):

upload_max_filesize = 32M
post_max_size = 32M
max_execution_time = 300	

1.2. files

• shows uploaded files for a specific page or global space
• Call: {{files [page="PageName" or global=1 or all=1 or linked=1] [order="ext|ext_desc|name_desc|size|size_desc|time|time_desc"] [owner="UserName"] [media=1] [max=Number] [nomark=1]}}
• Parameters:
  • page — define the name of the page, from which the list of files is to be loaded. If global=1, list of global space will be shown
  • order — sort file list by time, name, name_desc, size, size-in-reverse-order, and file extension
  • owner — show files owned by a specific user
  • media — parses image, audio and video links into their media tags — similar to a gallery
  • nomark — if set to 1, no border around the query result will be shown

2. Syntax of reference to the file

Local uploaded files, attached to a page, were check against the pages read permission.

2.1. URL syntax

• https://example.com/file/global/archive.zip — file in the global name space
• https://example.com/Dev/ToDo/Upload/file?get=archive.zip — file that was attached to a specific page
  • without rewrite-mode it looks like:
  • https://example.com/?page=Dev/ToDo/Upload/file&get=archive.zip

2.2. Wacko syntax

does search

1. file:archive.zip - checks for local file, that is only available to readers of this page
2. file:/archive.zip - only the global file
3. file:!/archive.zip - for local file with relative path
4. file:/Subpage/archive.zip - for local file with absolute path, necessary for local files to be included in another page

The absolute path is only needed if you want to include a local attached file into another page, which is rather an exception, in the majority of cases the user will embed the file in the same page. In this case the relative syntax should always be the preferred option, it is not only shorter, but also works after the page the file is attached to has been renamed.

2.2.1. Media Parameters

Parameters are added to the file syntax by appending a question mark ? and adding additional parameters by an ampersand &.
e.g. file:/image.png?200x400&direct&caption

• linking
  • direct - to file
  • nolink - shows only the image
  • linkonly - shows only link
  • meta - to filemeta handler (default)
• alignment
  • right
  • left
  • center
• resizing
  • 400x300 - width x height
  • 0x700 - height
  • 600 - width
• others
  • caption - shows caption
  • clear - clears float

Example:
file:/Groups/WackoWiki/mammut_800.jpg?500&caption

2.3. Embedding media files

Media files are rendered in their media tag such as <image>, <audio> or <video> unless otherwise declared.

3. File storage on server

Files for all users (global)
file/global/

Files of specific pages
file/perpage/

Files after backup (admin panel)
file/backup/

4. Customize upload settings

4.1. Edit constants: config.php

constants.php

<?php
...
const UPLOAD_GLOBAL_DIR                = 'file/global';
const UPLOAD_LOCAL_DIR            = 'file/perpage';
const UPLOAD_BACKUP_DIR                = 'file/backup';
...
	

• UPLOAD_GLOBAL_DIR — where are placed the public files
• UPLOAD_LOCAL_DIR — where are placed files only for users allowed to view current page, attached to the concrete pages

4.2. Edit secondary config
