Video length

Alright, long story short, the YouTube API doesn’t return duration during the “normal” API calls the plugin makes. This saves on API usage points but has the downside of not having duration.

This has been something that’s been “on the drawing board” to add to the plugin for some time.

I got things started a bit in light of this request. It’s not “integrated” into the plugin (yet) but the code below is tested and working over here.

You can drop it into a child theme functions.php or make a simple plugin out of it.

The code will check to see if you’re adding / updating a post with a YouTube video, and if so, attempt to update the duration if it’s not been previously set.

The duration is stored in two custom fields:

• tube_video_duration_hms is an array like this… array( ‘h’ => 0, ‘m’ => 3, ‘s’ => 47 )
• tube_video_duration_seconds is the total duration in seconds.

Give it a shot, and please mark resolved if it’s working for you. And if you dig the plugin, please consider leaving a review.

add_action('added_post_meta', 'tube_maybe_get_youtube_duration', 10, 4);
add_action('updated_post_meta', 'tube_maybe_get_youtube_duration', 10, 4);

function tube_maybe_get_youtube_duration( $meta_id, $post_id, $meta_key='', $meta_value='' ){
       
  // Do nothing unless correct key
  if ( $meta_key != 'tube_video_site' ) return;
  
  // only applied to youtube
  if ( $meta_value != 'youtube' ) return;

  // make sure it doesn't have duration already
  $has_duration = get_post_meta( $post_id, 'tube_video_duration_hms', true );
    
  if ( $has_duration ) return;
  
  tube_get_youtube_duration( $post_id );

}

function tube_get_youtube_duration( $post_id ){
  
  // get the video ID
  $video_id = get_post_meta( $post_id, 'tube_video_id', true );
  
  if ( ! $video_id ) return;
  
  // get the API key
  global $tube_video_curator;
  $youtube_api_key = $tube_video_curator :: $tube_youtube_videos -> get_youtube_api_key();
  
  if ( ! $youtube_api_key ) return;
  
  // generate the endpoint
  $endpoint = add_query_arg(
    array( 
      'part' => 'contentDetails',

     ),
    'https://www.googleapis.com/youtube/v3/videos'
  );
  
  // get the raw results
  $results_json = file_get_contents( $endpoint );
  
  // decode the results
  $results = json_decode( $results_json, true );
  
  // extract the duration
  $duration = $results['items'][0]['contentDetails']['duration'];
  
  // get the duraton parts  
  preg_match_all( '/PT(\d+H)?(\d+M)?(\d+S)?/', $duration, $duration_parts );
  
  // create HMS array
  $time_hms = array( 
    'h' => (int) str_replace( 'H', '', $duration_parts[1][0] ), 
    'm' => (int) str_replace( 'M', '', $duration_parts[2][0] ), 
    's' => (int) str_replace( 'S', '', $duration_parts[3][0] ) 
  );
  
  // calculate total seconds
  $time_total_seconds = ( $time_hms['h'] * 3600 ) + ( $time_hms['m'] * 60 ) + $time_hms['s'];
  
  // update the post meta
  add_post_meta( $post_id, 'tube_video_duration_hms', $time_hms );
  
  add_post_meta( $post_id, 'tube_video_duration_seconds', $time_total_seconds );  
  
  // all done
  return;
  
}

Are you actually looking in the database?

Or are you just looking at the Custom Fields meta box on the Edit Post page?

Assuming metabox, you will NOT see the tube_video_duration_hms there because it’s stored as a serialized array.

Try looking in your postmeta database table, or do a get_post_meta( $post_id, 'tube_video_duration_hms', true ) somewhere on the front end and you should see the hms value.

If it’s truly not being saved (unlikely) please provide a link to the video on YouTube.

This is “correct” in that the data IS stored as an array.

I think the issue with the way it’s being displayed.

The tube_video_duration_hms comes back as an array like this…

array( 
  'h' => 0, 
  'm' => 3, 
  's' => 47 
)

…so you’ll need to do something with it before you display it.

Simple example (not tested)…

$hms = get_post_meta( $post_id, 'tube_video_duration_hms', true );

echo sprintf( 
  'Duration: %1$d Hours %2$d Minutes %3$d Seconds', 
  $hms['h'], 
  $hms['m'], 
  $hms['s'] 
);

Of course you may want to get fancy with plural / singular or display it some other way but that should get you started.

Can you try this…

$hms = get_post_meta( $post_id, 'tube_video_duration_hms', true );

var_dump($hms);

Also, make sure the $post_id variable is properly set.

Depending on your theme, you may be able to use get_the_ID() there instead.
