RSS export and flash

Tuesday 07 February 2006 11:58:04 am

Im trying to make ez communicate with a .swf file in my template. I have managed to import text through the RSS output - but I would like the full url for the image also. So that this can be implemented into the .swf

Now the RSS just shows <Object> when I choose the class and attribute, and no url.

Any ideas?

Nothing to find there I think. But thanx.

I just need to know how to force the RSS feed to output a url to the full-version image-attribute of my class.

If I set "Title" in the RSS feed to my "Image"-attribute of the class - I would like to output the full url to this image in the feed, so that I can import this with a XML-connector in Flash. Iam not a hardcore Ez or Flash programmer, but I think this is the way to go - or am I just heading the wrong way here?

any inputs or other suggestions would be deeply appriciated....

Steph, one of ideas from given link above was to use layout module, then you have full control on the ouput because it is template base so you can construct your feed as you want, only one file to hack /kernel/layout/set.php where you have to add xml header "header( 'ContentType=text/xml' );"

If you want to hack RSS output look on file where feed is construct.
kernel/classes/ezrssexport.php

Other way you can create your new module, this will be correct way to handle this. However using layout module is faster ;)

In this case, using layout module can be easiest then coding new module. Performance is good enough.

I think using RSS word is a bit confusing here, you need export data from eZ publish to XML format and read this data in other "application". The bast way is to create new module, fetch data, pack it around xml tags, send correct header, and provide as source stream to Flash. That's all. RSS is a standard you don't have to follow it, in your case enough will be

<?xml version="1.0"?>
<item>
    <img-src>path to image</img-src>
</item>

Just loop throw fetched objects and take img path. Browse forum for examples. This will be the cleanest way, without hacking kernel, so you will don't have to care about future updates.

Look also on loadVariables

What Lukasz Serwatka says about hacking /kernel/layout/set.php will make it easier for viewing the xml in a browser, but flash reads the xml without editing the content type. Please correct me if I'm wrong here, but won't hacking /kernel/layout/set.php this way affect other layouts like "print" and "popup"?

Hi,

I tried to do what Lukasz Serwatka suggested in his last posting but I'm not successful. Here's what I did.

In a siteaccess override for layout.ini I created this group:

[xml]
PageLayout=alb_xml_pagelayout.tpl
ContentType=text/xml

Of course I also created the template alb_xml_pagelayout.tpl which contains just some simple XML for test reasons.

Then I added the Code that Lukasz suggested into kernel/layout/set.php. That you can see where I added it, I'm showing you the line before and after my insertion:

if ( $layoutINI->hasVariable( $LayoutStyle, 'PageLayout' ) )
        $Result['pagelayout'] = $layoutINI->variable( $LayoutStyle, 'PageLayout' );

    if ( $layoutINI->hasVariable( $LayoutStyle, 'ContentType' ) )
        header( 'Content-Type: ' . $layoutINI->variable( $LayoutStyle, 'ContentType' ) . ' charset=' . $i18nINI->variable( 'CharacterSettings', 'Charset' ) );

    include_once( 'kernel/common/eztemplatedesignresource.php' );

But now, when I'm viewing a node using this layout, I'm getting this error message:

"<b>Fatal error:</b> Call to a member function on a non-object in <b>/var/albwww/ez/kernel/layout/set.php</b> on line <b>57</b>
<b>Fatal error:</b> eZ publish did not finish its request

The execution of eZ publish was abruptly ended, the debug output is present below."

I think that the usage of header() causes this problem, maybe it isn't allowed to use. But which function should I use instead? I tried to find information about setting headers etc. in this forum and the documentation, but didn't find anything.

Can anybody help me?

Thanks a lot, Kristof, now it works!

Just a note to the people who try to do the same: there's a little error in Lukasz Code he posted, concerning a missing semicolon in the header field's content which causes IE to fail loading the xml (but FF does, however).

Here's the corrected code:

if ( $layoutINI->hasVariable( $LayoutStyle, 'ContentType' ) )
        header( 'Content-Type: ' . $layoutINI->variable( $LayoutStyle, 'ContentType' ) . '; charset=' . $i18nINI->variable( 'CharacterSettings', 'Charset' ) );
