Symphony.

Hi,

I have the following problem I am trying to solve. I store mulitple youtube videos, by storing their key. Now I use the Youtube API to get some XML data about the videos according to their key. So I have an entry with key XXXXXXXX, and I use a parameter output wich creates a {$ds-youtube}-parameter. This parameter I use in another datasource which loads a dynamic URL located at http://gdata.youtube.com/feeds/api/videos/{$ds-youtube}

This works when I only have one entry, because then {$ds-youtube} will be ‘XXXXXXXX’.

But… when I have multiple entries, {$ds-youtube} will be ‘XXXXXXX1, XXXXXXX2, XXXXXXX3, etc’

Also, in both cases, the XML-output will be:

<youtube>
  <entry>
    ...
  </entry>
</youtube>
<youtube-detail>
  ...
</youtube-detail>

Where I want the output to be similar to:

<youtube>
  <entry>
    ...
    <youtube-detail>
      ...
    </youtube-detail>
  </entry>
</youtube>

Does anyone know how I can achieve this?

Thanks in advance!

Sounds like you’ll need to customize your dynamic XML DS to iterate over the available Youtube keys and fetch the XML data one-by-one. Then you can build the XML however you like.

Sorry to bring up this old post but i've ran into the same situation.

I've readed at stackoverflow i can query several videos info by id using a query like:

http://gdata.youtube.com/feeds/api/videos?q=videoid-1|videoid-2|videoid-3

If i could simply add a replace funcion in the DS, something like this imaginary dynamic XML datasource.

http://gdata.youtube.com/feeds/api/videos?q={replace($param,', ','|')}

Is this doable? I know you can do some advanced regexp and filtering in DS filter fields, that's why i ask.

If this can't be done i guess i need to create a custom datasource. This datasource would take as param a videos id list and perform the youtube batch api operation. I guess that would be much better than 30 or 40 unique requests for a video list page.

To be honest, i readed the datasources related code and i'm not sure on how to proceed "correctly", any tip, just a pointer on how to get started will be much apreciated.

My final goal is to easily use youtube stored data, things like publish date, thumbnails, duration, etc.

First attempt:

I edited the dynamic xml datasource and changed the default include in the grab function:

try{
     include(TOOLKIT . '/data-sources/datasource.youtube_dynamic_xml.php');
}

datasource.youtube_dynamic_xml.php is a copy of datasource.dynamic_xml.php where i added a str_replace line:

if(isset($this->dsParamURL)){
    $params = findParametersInString($this->dsParamURL);
    foreach($params as $key => $info){
        $replacement = $this->__processParametersInString($info['param'], $this->_env, false);
        if($info['encode'] == true){
            $replacement = urlencode($replacement);
        }

        $this->dsParamURL = str_replace("{{$key}}", $replacement, $this->dsParamURL);
        //custom line.
        $this->dsParamURL = str_replace(",", "|", $this->dsParamURL);
    }
}

While i achieved what i wanted it feels a bit dirty. Also, it did not solve my problem since the suggested youtube query using "|" and video ids is not very trustable, it breaks when a video id has a "-" character.

Just wanted to explain the dirty hack i tried so i may get corrected.

My next step is diggin more into youtube api.

I've found this "Youtube Videos" extension. It solves all my needs.
