hi there
a while back, hans had worked out the following function so that URLs
ending in .pdf, mp3, etc, would automatically receive
<a class='medialink pdf' ...
so that links to such media could be styled.
here's what that looked like:
$MediaExtPat = "mp3|ogg|aif|wav|mov|avi|mp4|m3u|doc|rtf|ods|txt|
pdf";
$LinkFunctions['http:'] = 'MediaLinkIMap';
function MediaLinkIMap($pagename,$imap,$path,$title,$txt,
$fmt=NULL) {
global $UrlLinkTxtFmt,$MediaExtPat;
if (!$fmt)
$fmt = (preg_match("/($MediaExtPat)$/", $path, $m)) ?
"<a class='medialink {$m[1]}' href='\$LinkUrl'
rel='nofollow'>\$LinkText</a>"
: $UrlLinkTxtFmt;
return LinkIMap($pagename,$imap,$path,$title,$txt,$fmt);
}
the problem i'm running into is that it worked for full URLs, but not
for uploaded files displayed via 'Attach:'.
i thought that combining the MediaLinkIMap function with the
LinkUpload function (from upload.php) would solve this problem (see
my solution below), and it does in fact add the correct styling - but
it breaks all my images.
for instance, these don't display anymore:
Attach:Group./image.jpg
image link: [[http://blah.com|Group./image.jpg]]
any ideas what i can do to correct this?
thanks!

# For Attach: -- the MediaLinkIMap function only works for http:, but
not for Attach:
# this function is taken from the upload.php recipe in the scripts/
folder
$LinkFunctions['Attach:'] = 'MediaLinkIMap';
function MediaLinkUpload($pagename, $imap, $path, $alt, $txt,
$fmt=NULL) {
global $FmtV, $UploadFileFmt, $LinkUploadCreateFmt, $UploadUrlFmt,
$UploadPrefixFmt, $EnableDirectDownload, $MediaExtPat;
if (preg_match('!^(.*)/([^/]+)$!', $path, $match)) {
$pagename = MakePageName($pagename, $match[1]);
$path = $match[2];
}
$upname = MakeUploadName($pagename, $path);
$filepath = FmtPageName("$UploadFileFmt/$upname", $pagename);
$FmtV['$LinkUpload'] =
FmtPageName("\$PageUrl?action=upload&upname=$upname",
$pagename);
$FmtV['$LinkText'] = $txt;
if (!file_exists($filepath))
return FmtPageName($LinkUploadCreateFmt, $pagename);
$path = PUE(FmtPageName(IsEnabled($EnableDirectDownload, 1)
? "$UploadUrlFmt$UploadPrefixFmt/$upname"
:
"{\$PageUrl}?action=download&upname=$upname",
$pagename));
if (!$fmt)
$fmt = (preg_match("/($MediaExtPat)$/", $path, $m)) ?
"<a class='medialink {$m[1]}' href='\$LinkUrl' rel='nofollow'>\
$LinkText</a>"
: $fmt;
return LinkIMap($pagename, $imap, $path, $alt, $txt, $fmt);
}
