Extension talk:FaviconLink

Here's a link to various Microsoft Office and Windows programs.--Hoggwild5 02:09, 18 February 2007 (UTC)

I added the XSS alert because this works:

<ilink>"><script>alert('hello');</script></ilink>

Some Improvements

There are two issues with the current version:

• if the target site has no favicon, an ugly placeholder is shown
• some sites use favicons larger than the usual 16x16 pixels, this may look bad especially in lists of links

Replacing

return "<a href=\"".$link."\"><img src=\"".$favicon."\"> ".$linkname."</a>";

with

$headers = @get_headers($favicon);
$iconExists = (preg_match("|200|", $headers[0]) != 0); // check for the HTTP return code; 200 means 'OK'
global $wgIconLinkDefaultIcon;
if (! $iconExists) { $favicon = $wgFaviconLinkDefaultIcon; }
return '<a href="'.$link.'"><img src="'.$favicon.'" width="16" height="16"> '.$linkname.'</a>';

should solve these issues. The default icon can be defined in LocalSettings.php:

$wgFaviconLinkDefaultIcon = "extensions/FaviconLink/default.png";

Hi @Roberthaenel,

Great - your improvment code works! But sorry for asking - I do not understand what exactly should be shown/appear as result, IF the target site has no favicon (e.g. an icon, so that all links and favicons are -vertically- in line)?

I mean, if through your new code simply no favicon should appear (because the site simply do not have a favicon), I think in this case I would simply not use the <ilink>-extension(-tags) OR would simple replace it (instead a placeholder or whatever) through the browsers "no favicon icon" or maybe any other icon. Therefore, it would be a nice next improvement, if your code would be able to automatically replace the "no icon place" with the browsers "no favicon icon" (similar as browsers do so in such a case) or a possibility to replace the "no favicon place" with any other -wished- icon (or maybe a possibility to use both examples) ...

Hi 80.109.228.11

I have updated the code to show a default icon.

@ Roberthaenel - THANK'S! I have just seen your similar Extension:IconLink. Your own extension is great too, so currently I have no idea, which one I should finally use ( ; - ) ... because both extensions are great!

Thank's again! --80.109.228.11 00:08, 6 April 2008 (UTC)
