[Catalyst] display multiple png's simultaneously
Hi,
I am developing a small "media bookshelf" where I want to display in a
matrix-like layout - among other informations - covers in png format (which are
saved in a BLOB in my Mysql-DB). I have something like [1] in my mind. The
problem I have now is, that only ONE cover is displayed at a time. The relevant
code looks like this:
matrix.tt2:
---
[% FOREACH m IN medien %]
[% IF ! (loop.count mod 4) %]
[% END %]
[% m.titel %]
[% m.typ %]
[% END %]
Medien.pm:
--
sub cover :Chained('object') :PathPart('cover') :Args(0) {
my ($self, $c) = @_;
my $medium = $c->stash->{object};
$c->response->header('Content-Type' => $medium->mime . ";
charset=\"ISO-8859-1\"");
$c->response->write($medium->cover);
}
I think I now where the problem is, but I do not know how I can fix it
properly: The cover action in my Medien controller works with $c->response and
therefor creates a new response for each object-tag in my tt2. So only the
"last" cover is displayed.
Can anybody help me on how I get all covers displayed simultaneously?
Thanks
Jürgen

Re: [Catalyst] display multiple png's simultaneously
Hy!
The code, looks good to me, the problem maybe in the action that
captures the argument for the chain, to confirm that, please check that
all the object's data attributes generated right, and check the debug
output for the server to see if all the object's requests, succeeds (
you can see the error messages that catalyst generates for the images,
if you change the object's to iframes... so then the images may display
ugly, but you can see the error messages it they sent instead of an image...

Re: [Catalyst] display multiple png's simultaneously
Hi Tamás, according to the server's debug output, all images are created correctly (ie. the requests succeed). If I switch from the object tag to iframe, all images (except the last one which is displayed correctly) produce an error message in their iframe's: "Die Grafik http://... kann nicht angezeigt werden, weil sie einen Fehler enthält" (Something like "The image http://... cannot be displayed because it contains an error.") Any idea?

Hmm, never mind: I don't know *what* I changed, but now it seems to work as intended - i.e. *all* covers are displayed simultaneously. confused greetings Jürgen -- Jetzt kostenlos herunterladen: Internet Explorer 8 und Mozilla Firefox 3.5 - sicherer, schneller und einfacher! http://portal.gmx.net/de/go/chbrowser ___ List: Catalyst@lists.scsys.co.uk Listinfo: http://lists.scsys.co.uk/cgi-bin/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/catalyst@lists.scsys.co.uk/ Dev site: http://dev.catalyst.perl.org/
