Working with the YouTube API

[siobhyb]

Hi,

 

I'm working with the YouTube API to echo a feed based on a user's query.

 

My current code is below.  With this code, a whole list of videos is retrieved.

 

However, in order to present the feed as I wish to... I need to return each video in the feed individually. 

 

I am unsure how to do this and any advice would be really appreciated.

 

 $feedURL = "http://gdata.youtube.com/feeds/api/videos/-/$youtubeQuery?orderby=viewCount&max-results=10";
                
          // read feed into SimpleXML object
          $sxml = simplexml_load_file($feedURL);

          // iterate over entries in resultset
          // print each entry's details

          foreach ($sxml->entry as $entry) {
          // get nodes in media: namespace for media information
          $media = $entry->children('http://search.yahoo.com/mrss/');
                  
          // get video player URL
          $attrs = $media->group->player->attributes();
          $watch = $attrs['url']; 
                  
          // get video thumbnail
          $attrs = $media->group->thumbnail[0]->attributes();
          $thumbnail = $attrs['url'];
                  
          // get <yt:duration> node for video length
          $yt = $media->children('http://gdata.youtube.com/schemas/2007');
          $attrs = $yt->duration->attributes();
          $length = $attrs['seconds'];

          // get video title
          $title = $media->group->title;
                 
          // get <gd:rating> node for video ratings
          $gd = $entry->children('http://schemas.google.com/g/2005'); 
          if ($gd->rating) {
          $attrs = $gd->rating->attributes();
          $rating = $attrs['average'];
          } else {
          $rating = 0;
          }
            
          }
          ?>

Im not sure about the output from the feedURL variable (and I'm on my iPhone now so I can't test it) but if you could use

 echo "<pre>".file_get_contents($feedURL)."</pre>"

That would at least tell you what you're dealing with. 

You may have nested arrays which you can then deal with easily.

Hi,

 

I'm still a bit stuck with this.

 

I've got the original code...

 

    $feedURL = "http://gdata.youtube.com/feeds/api/videos/-/royalwedding?orderby=viewCount&max-results=10";
                
          // read feed into SimpleXML object
          $sxml = simplexml_load_file($feedURL);

          // iterate over entries in resultset
          // print each entry's details
          foreach ($sxml->entry as $entry) {
          // get nodes in media: namespace for media information
          $media = $entry->children('http://search.yahoo.com/mrss/');
                  
          // get video player URL
          $attrs = $media->group->player->attributes();
          $watch = $attrs['url']; 
                  
          // get video thumbnail
          $attrs = $media->group->thumbnail[0]->attributes();
          $thumbnail = $attrs['url'];
                  
          // get <yt:duration> node for video length
          $yt = $media->children('http://gdata.youtube.com/schemas/2007');
          $attrs = $yt->duration->attributes();
          $length = $attrs['seconds'];

          // get video title
          $title = $media->group->title;
                 
          // get <gd:rating> node for video ratings
          $gd = $entry->children('http://schemas.google.com/g/2005'); 
          if ($gd->rating) {
          $attrs = $gd->rating->attributes();
          $rating = $attrs['average'];
          } else {
          $rating = 0;
          }

 

If I echo the following code...

 

 // print record

echo "<div class=fvid><a href=\"{$watch}\"><img src=\"$thumbnail\"/></a></div>";

echo "<ul class='vidselector'><li><a href=\"{$watch}\">{$media->group->title}</span></a></li></ul>";

 

Then the last video in the feed in printed out.

 

If I put the same code in the "For" loop then all the videos in the feed are printed out. 

 

I want to find a way of choosing which videos in the feed I want to display.  For example, maybe just the third, fourth and sixth.

 

I don't know how to begin doing this.  Any advice would be really appreciated.  Thank you.
