Inline Uploaded Images

After having installed (and patched) the Upload Plugin? (see PhpWiki:Upload), and setup the Inter Wiki Map (to File: /wiki/uploads), one might well like to upload images, and expect to be able to inline them in a wiki page using the [File:my_image.gif] form.

Well, to do this is not too complicated (phpwiki 1.3.4), patch interwiki.php and stdlib.php.

This actually allows any interwiki image inlining.

• [File:my_image.gif] inlines the image
• File:my_image.gif shows a plain inter-wiki link
• [what a pic|File:my_image.gif] shows a named inter-wiki link

interwiki.php: add method linkImage()

    function linkImage ($link, $alt = false) {

        list ($moniker, $page) = split (":", $link, 2);

        if (!isset($this->_map[$moniker])) {
            return HTML::span(array('class' => 'bad-interwiki'),
                              $linktext ? $linktext : $link);
        }

        $url = $this->_map[$moniker] . $page;

        $link = HTML::img(array('src' => $url, 'alt' => $alt));
        $link->setAttr('class', 'inlineimage');

        return $link;
    }

stdlib.php: use linkImage()

function LinkBracketLink($bracketlink) {
    global $request, $AllowedProtocols, $InlineImages;

    include_once("lib/interwiki.php");
    $intermap = InterWikiMap::GetMap($request);

...

    elseif (! $label && preg_match("/^" . $intermap->getRegexp() . ":.*($InlineImages)$/i", $link))
        return $intermap->linkImage($link, $link);
    elseif (preg_match("/^" . $intermap->getRegexp() . ":/", $link))
        return $intermap->link($link, $label);
    else {
        return WikiLink($wikipage, 'unknown', $label);
    }
}
