What can this extension do?

This extension has this purposes:

  • Allow URI linking to files that are uploaded into your wiki
  • Allow UNC linking to files stored on your intranet "\\servername\path\filename.ext"

The link can be for documents of type:

  • image
  • simple link

The very useful if your wiki is housed internally and used for as an intranet for your company.

Usage

edit

Syntax

edit

This extension get us a new tag, with it,we can insert links (on URI or UNC format) to documents not incorporated at your wiki. <document_unc></document_unc>

Syntax: 

<document_unc 
     width=['100%'|'300px'] 
     heigth=['20%'|'300px'] 
     type=['embeded'|'image'|'link']
     link='unc|uri'
     margin='units' 
>
 [unc|uri]|label]
</document_unc>

Where:

  • width : It's the width for the object into the page, use pixels or percent units.
  • height : It's the height for the object into the page, use pixels or percent units.
  • type : It's the way for interpreting you URI, you have three choices:
  • link: Default, the tag it's intepreted like simple link. Its can use in combitation with label.
  • image: The tag it's intepreted like an URI to an image whose default link is to itself (if you not especify link). Its can use in combitation with label and link.
  • embeded: The tag it's intepreted like an URI to a document embeded. It works with PDF files!.
  • link : With this, you can specify an alternate URI at witch the navegator it go when press click over the image. Obviously only functions in combination with type='image'.
  • margin: With this, you can specify an margin to apply at the object to be incrusted, the margin to be added it's vía styles (CSS); from here that the format for units it's the same that supports the tag margin from CSS. Into the string value don't specify ';'.

On tag value exists two options:

  • uri or unc : Its about the path at your resource. You can specify the format UNC(\\server\ruta\file.ext) o URI (/ruta/file.ext)
  • label : Its the text to be displayed... this operates of any of the following forms:
  • Like Alternative tag (ALT="") when it is used in combinaciòn with type='image'
  • Like Link-text when it is used in combinaciòn with type='link'

Like image

edit
  • Sintax 1:
  • <document_unc width="100px" type="link">{{SERVER}}\wiki\docs\example.jpg|Mi example image<document_unc>
  • On this case you get a image with three properties:
  • width: 100px
  • A caption: Mi example image
  • A URI destination on click: A new page with just the full image.
  • Sintax 2:
  • <document_unc width="100px" type="link" link="http://www.mediawiki.org">{{SERVER}}\wiki\docs\example.jpg|Mi example image<document_unc>
  • On this case you get a image with three properties:
  • width: 100px
  • A caption: Mi example image
  • A URI destination on click: The MediaWiki.org principal page. It's very important put http:// otherwise the URI will be interpreted like relative on your site.
