New subject: [Mediawiki-l] Custom parser function returning raw code

30 Dec 2007


      Hello,
Due to parser tags not being able to correctly handle variables such
as {{{1}}} I created my own custom parser function that calls a parser
tag I've installed so that I could use such variables with it.
Unfortunately instead of outputting the actual image that it should do
it outputs the code raw - I've verified this is something to do with
the parser as I have done some testing and can confirm that before it
is return-ed it is still HTML code, not escaped HTML code. Below is a
copy of my custom code for anyone who is interested in helping. Any
assistance would be greatly appreciated.
<?php
/* Parser Function style work around, calls above function. */
$wgExtensionFunctions[] = 'wfImageLinkWorkAroundParserFunction_Setup';
$wgHooks['LanguageGetMagic'][] = 'wfImageLinkWorkAroundParserFunction_Magic';
function wfImageLinkWorkAroundParserFunction_Setup() {
    global $wgParser;
    $wgParser->setFunctionHook( 'link',
'wfImageLinkWorkAroundParserFunction_Render' );
}
function wfImageLinkWorkAroundParserFunction_Magic( &$magicWords, $langCode ) {
    $magicWords[ 'link' ] = array( 0, 'link' );
    return true;
}
function wfImageLinkWorkAroundParserFunction_Render( &$parser, $target
= '', $alt = "", $src = "", $height = "", $width = "" ) {
    $img = new LinkedImage;
    $img->wikipage = $target;
    $img->tooltip = $alt;
    $img->img_src = $src;
    $img->img_alt = $alt;
    $img->img_height = $height;
    $img->img_width = $width;
    $img->img_border = 0;
    #echo $img->render(); # Outputs actual HTML (e.g. <img src="foo" />)
    return $img->render(); #' Outputs escaped HTML (e.g. &lt;img src="foo" /&gt;)
}
?>
