I am trying to: Count the number of times a multiple-instance field has been used. For example, I am using a multiple-instance field to enter songs/tracks on an album. I would like to be able to display the number of tracks on each album in the content template.

Specifically, the reason for this is I am attempting to use the Schema.org markup for Music Album, which asks for the number of tracks. hidden link

For example:

<meta content="8" itemprop="numTracks" />

Would there be a way to count the number of the multiple-instance field I'm using for tracks on the album to fill in the

content="8"

?

You can try create a custom shortcode for it, for example another similar thread:

That solution works for me!

In case anyone else stumbles upon this thread, the final solution was to create a shortcode in a plugin like this:

//Shortcode to display number of tracks on an album
add_shortcode( 'count-tracks', 'count_tracks_func' );
function count_tracks_func($atts) {
    return sizeof(get_post_meta( get_the_ID(), 'wpcf-' . $atts['field'], false));
}

Then in the Content Template for the album, I was able to use this shortcode to display the number of tracks on the album:

[count-tracks field="track-listing"]

This can then be used with the schema markup for MusicAlbum like this:

<meta content='[count-tracks field="track-listing"]' itemprop='numTracks' />
