PmWiki can be configured to allow authors to upload and attach files to pages. Each Wiki Group can have its own collection of named attachments that are shared among all pages in the group. To add or link to an attachment, an author edits a page to include the markup "
Attach:" followed by a name of an attachment (e.g., "
Attach:resume.pdf"). When the page is displayed, the
Attach: markup becomes one of the following:
To have a link to an attachment appear without the "
Attach:" at the beginning of the link, use
To link to attachments on another page or WikiGroup, use
One can go directly to the upload form by appending "?action=upload" to the URI for any page that has file uploads enabled by the Wiki Administrator.
For security reasons, the upload feature is disabled when PmWiki is first installed; once enabled, uploads are generally restricted as to the types and sizes of files that may be uploaded to the server (see UploadsAdmin). PmWiki's default configuration limits file sizes to 50 kilobytes and file extensions to common types such as ".gif", ".jpg", ".doc", ".txt", and ".pdf". In addition, the administrator can configure the system to require an
upload password--see Passwords and PasswordsAdmin.
By default the upload allows the following extensions:
'gif','jpg','jpeg','png','bmp','ico','wbmp', # images 'mp3','au','wav', # audio 'mpg','mpeg','wmf','mov','qt','avi', # video 'zip','gz','tgz','tar','rpm','hqx', # archives 'doc','ppt','xls','exe','mdb', # MSOffice 'pdf','psd','ps','ai','eps', # Adobe 'htm','html','fla','swf', # web stuff 'txt','rtf','exe','tex','dvi','' # misc
At present uploaded files can only be deleted from the server by the wiki administrator. Any uploads-authorized user may over-write an existing file by uploading another of the same name and extension to the same location.
