Smugmug extension for MediaWiki

<digg />

Overview

This extension allows embedding images from Smugmug into a MediaWiki wiki.

<smugmug>206695594|right|thumb|s|example image embedded from smugmug</smugmug>

Syntax

Based on the basic syntax for images in a wiki, the full syntax for displaying an image from smugmug is:

<smugmug>{id}|{type}|{location}|{size}|{caption}</smugmug>

OR

<smugmug id="{id}" type="{type}" location="{location}" size="{size}" caption="{caption}"></smugmug>

• {id} is required.
• {type} can be thumb, thumbnail, or frame. This controls how the image is formatted. Default is none. For between-tag parameters, do not explicitly set "none" as it would be interpreted as location.
• {location} can be left, right, center, or none: Controls the alignment of the image(s) on the page. Default is none
• {size} can be Tiny, Thumbnail, Square, Medium, Large, Original, or their short name counterparts: Ti, Th, S, M, L, O. Default is Medium
• {caption text} is the caption text

The options are not case-sensitive and can be given in any order. If a given option does not match any of the other possibilities, it is assumed to be the caption text. Caption text can probably contain wiki links or other formatting, (not tested yet).

Caption text will default to the caption on Smugmug, or the keywords on Smugmug if the caption does not exist.

Options given as attributes will override options between the tags.

Examples

<source lang="xml"> <smugmug>206695566</smugmug> </source>

Display a medium-sized photo with no formatting

<source lang="xml"> <smugmug>206695594|right|thumb|s</smugmug> </source>

Display a small-sized photo on the right in a thumbnail frame

<source lang="xml"> <smugmug id="206695594" location="right" type="thumb" size="s"></smugmug> </source>

Same as above, but with parameters given as attributes instead of between tags

Requirements

Smugmug extension for MediaWiki requires

1. an installation of MediaWiki
2. Colin Seymour's PHP wrapper, phpSmug

Installation

1. Download phpSmug and install it on your server. Don't worry about "Usage" on the phpSmug page, but of course you'll need to remember where you installed it.
   • (This is probably overkill on details, but here's my Log of installation of phpSmug.)
2. Get a smugmug API key
   • Name: Smugmug extension for MediaWiki
   • Type: Plug-in
   • Platform: All
   • Use: Non-Commercial
   • Description:
     • if you will only make changes as described on this page, just use http://robnugen.com/wiki/index.php?title=Smugmug_extension_for_MediaWiki
     • otherwise, write whatever is appropriate for you. I'd love to get a note on how you are using it!
3. Copy the source code below into a file in your extensions directory: (e.g. wiki/extensions/Smugmug.php)
4. overwrite PATH TO YOUR LOCAL phpSmug in Smugmug.php with the location you chose in step 1
5. overwrite COPY YOUR SMUGMUG API KEY HERE in Smugmug.php with your new API key from step 2
6. Add the following line to the bottom of your MediaWiki's LocalSettings.php file:
   • <source lang="php">require_once("$IP/extensions/Smugmug.php");</source>
