Development of Files action


This is the development page for the {{files}} action.
  • For info about the version currently included in Wikka, take a look at Mod015fFilesAction.
  • For a documentation of how to use the current version, look at FilesActionInfo.
 


handlers/page/files.xml.php didn't work for me, so i use FilesActionHillar

Actual version


The code below offers a more visually improved layout for this handler and also displays the file size and the date of file upload.

Nice.. but shouldn't delete at least check some permissions? (answer: I am checking write permission...)
-- ArnarBirgisson

Why "files.xml"? shouldn't it be "files.php"? (answer: .xml actions does not include header and footer)
(files.xml didn't work, but renaming it to "files.xml.php" helped.)
=> Kommentar::
files-action only works if you copy files.xml and store it as files.xml.php as well as files.xml ??????????

Jetzt geht es, aber das ist ziemlich irre, weil ::
- files.xml
noch einmal als ::
- files.xml.php
abgespeichert werden muss. ?? es funktioniert ..

:: FileUp ::
By the way, having an upload form on a page seems to break the page preview "Store" and "Re-edit" buttons.
(fixed hidding the form on editing, thanks for your bug information)
-- Tero

Here is the same bug like in ImageAction: the use of $vars. Replace line 11 to 16 in actions/files.php with this:
 if ($tokens['download'] ) {

 // link to download a file
 $text = $this->stripquotes($action_params['download']);
 if ($tokens['text'])
 {
  $text = $this->stripquotes($action_params['text']);
 }
 echo "<a href=\"".$this->href('files.xml',$this->GetPageTag(),'action=download&file='.urlencode($this->stripquotes($action_params['download'])))."\">".$text."</a>";
}


For the function $this->stripquotes read ImageAction
--SilBaer

Fileupload on editing pages see FileUpload
--SilBaer

Fix: Added closing CurlyBrace in last replacement code.

I cleaned up the code and added:

Hope you like it.

yet another actions/files.php


http://wush.net/trac/wikka/ticket/72

it is not said in the ticket, but of course my version is also fully css skinable.

some other changes:

as i state in the ticket also, the upload file limit is not working for me. see the ticket


styling the file upload form


people might get frustrated by the browse button and the file input field.
this page offers a solution: http://www.quirksmode.org/dom/inputfile.html
Not a good solution: it requires JavaScript, and the field itself accepts no (typed) input any more (in a normal file upload field you can type or paste a path - that doesn't work on any of PPK's examples): that beaks basic functionality. The only "frustration" is the lack of styleability of the button - well, too bad, at least it's accessible (provided there's also a label, of course), and that's more important. -- JavaWoman


making uploaded images useful


to make the wiki a truly useful documentation tool, one needs pictures, uploaded pictures.
at the moment pictures uploaded using FilesAction are accessible only for download
(unless i am missing something). to let a department manage it's own pictures and be
able to include them in the page, one needs to access $upload_path. the current
.htaccess file makes this impossible.

so here is what i did:

.htaccess

<IfModule mod_rewrite.c>
 RewriteEngine on
 RewriteCond %{REQUEST_FILENAME} -d
 RewriteRule ^(.*/[^\./]*[^/])$ $1/

 RewriteCond %{REQUEST_FILENAME} !robots.txt
 RewriteCond %{REQUEST_FILENAME} !favicon.ico
 RewriteCond %{REQUEST_FILENAME} !files/.*$
 RewriteRule ^(.*)$ wikka.php?wakka=$1 [QSA,L]
</IfModule>


in the wikka page:

{{image alt="db model" title="db model" url="files/CostCenters/costcenters.png"}}

this way i can include the images for viewing in the page.
