This is a trivial patch of MediaWiki Extension:Anysite to shift x-wise the included frame.

<?php

1. Minseong Extension
3. Tag :
4. <anyweb>website</anyweb>
5. Ex :
6. from url http://aurora1.sourceforge.net
7. <anyweb>http://aurora1.sourceforge.net</anyweb>
8. <anyweb mywidth="800" myheight="600" myshift="30">http://my.server.com/</anyweb> to shift x-wise -- F.P.L. laussy.org
10. Enjoy !

$wgExtensionFunctions[] = 'wfanyweb'; $wgExtensionCredits['parserhook'][] = array(

       'name' => 'anysite extension',
       'description' => 'Display sites',
       'author' => 'Minseong Kim and Others',
       'url' => 'http://www.mediawiki.org/wiki/Extension:Anysite'

);

function wfanyweb() {

       global $wgParser;
       $wgParser->setHook('anyweb', 'renderanyweb');

}

1. The callback function for converting the input text to HTML output

function renderanyweb($input, $argv) {

       if (isset($argv['mywidth'])) {
               $width = $argv['mywidth'];
       } else {
               $width = 770;
       }       
       if (isset($argv['myheight'])) {
               $height = $argv['myheight'];
       } else {
               $height = 500;
       }
       if (isset($argv['myshift'])) {
               $shift = $argv['myshift'];
       } else {
               $shift = 30;
       }
       $output= '<iframe style="position:relative; right:'.$shift.'px;" name="anyweb" src="'.htmlspecialchars($input).'" width="'.$width.'" height="'.$height.'" frameborder="0">'.'</iframe>';                 
       return $output;

}

You can now use

<anyweb myshift="30">http://wikipedia.org</anyweb>

to shift it 30px from the right (i.e., on the left).
