Following on from [the previous
post](http://iphylo.blogspot.com/2008/10/books.html), I wrote a simpe
Mediawiki extension to insert a Google Book into a wiki page. Written in
a few minutes, not tested much, etc. 
 
To use this, copy the code below and save in a file **googlebook.php**
in the **extensions** directory of your Mediawiki installation. 
 

``` {style="border: 1px solid rgb(199, 207, 213);margin: 20px 0pt; padding: 15px; background: rgb(241, 245, 249)"}
# rdmp

# Google Book extension
# Embed a Google Book into Mediawiki
#
# Usage:
# 
# 
# To install it put this file in the extensions directory 
# To activate the extension, include it from your LocalSettings.php
# with: require("extensions/googlebook.php");
 
$wgExtensionFunctions[] = "wfGoogleBook";
 
function wfGoogleBook() {
 global $wgParser;
 # registers the extension with the WikiText parser
 $wgParser->setHook( "googlebook", "renderGoogleBook" );
}
 
# The callback function for converting the input text to HTML output
function renderGoogleBook( $input, $argv ) 
{
 $width = 425;
 $height = 400;
 
 if (isset($argv["width"]))
 {
 $width = $argv["width"];
 }
 if (isset($argv["height"]))
 {
 $width = $argv["height"];
 }
 
 $output = ' src="http://books.google.com/books/previewlib.js">
 ';
 $output .= ' GBS_insertEmbeddedViewer(\'' . $argv["id"] . '\','. $width . ',' . $height . '); '; 

 return $output;
}
?>
```

 
 
In your **LocalSettings.php** file add the line 
 

``` {style="border: 1px solid rgb(199, 207, 213);margin: 20px 0pt; padding: 15px; background: rgb(241, 245, 249)"}
require("extensions/googlebook.php");
```

 
 
Now you can add a Google book to a wiki page by adding a tag. For
example: 
 

``` {style="border: 1px solid rgb(199, 207, 213);margin: 20px 0pt; padding: 15px; background: rgb(241, 245, 249)"}
```

 
 
The **id** gives the book identifier (such as an OCLC number or a ISBN
(you need to include the identifier prefix). By defaulot, the book will
appear in a box 425 × 400 pixels in size. You can add optional **width**
and **height** parameters to adjust this.
