[opensuse] [Fwd: Re: [Mediawiki-l] using images as icons]

Tue, 30 Aug 2005 12:39:47 -0700

For enhancing the aspect of the opensuse pages, the use of images is very nice. However, mediawiki images use to link only to they own page, so clicking on the image don't send to the link waited by most users (the normal icons way);
I asked about this on the mediawiki list and was answed this (below). 


could somebody test this and if good insert the appropiate 
code? I've no php knowledge and can't do it myself


thanks
jdd

Did some more thinking.. the only solution I can see is some kind of
extension designed to do this.


Yep.
Untested, but should work.

extensions/ImageLink.php:
--snip--
require_once('../includes/Image.php');

$wgExtensionFunctions[] = "wfImageLink";

function wfImageLink()
{
    global $wgParser;
    $wgParser->setHook ('imglink', 'renderImageLink');
}

function renderImageLink ($text, $attr)
{
    global $wgParser, $wgUser, $wgTitle;
    $parserOptions = ParserOptions::newFromUser( $wgUser );
    $parser =& new Parser();

    $output =& $parser->parse("[[".$input."|IMAGE]]", 
$wgTitle, $parserOptions);

    $ret = $output->getText();
    $itag = "<img border='0' ";
    foreach ($attr as $k => $v) {
        if ($k == "src") {

            $itag .= "src='" . 
Image::imageUrl($attr['src']) . "' ";

        } else {
            $itag .= "$k='$v' ";
    }
     $itag .= "/>";
    return str_replace ($ret, "IMAGE", $itag);
}
--snip--
and add
  require_once('extensions/ImageLink.php');
to LocalSettings.php.

To use, do
<imglink src='MyImage'>Destination page</imglink>
instead of the doesn't-work
[[Destination page|[[Image:MyImage]]]]

You can also use height and width attributes on the 
<imglink> tag.


Hope this helps.
