Each discography entry has a playa field for each disc that contains all the songs that appear on that record, creating a tracklisting. What I'd like to do is create a reverse navigation system, so that people can browse songs and see all releases they appeared on (albums, singles, collections, etc).

It was straightforward to get Low Alphabet to ouput a page containing all songs starting with a letter, now I'd like to have all parent releases listed under them.

I imagine it's something where I'd need to write some custom PHP or use an embed or stash based on research I've been doing.

Relevant template code below - it just outputs a long list of entries (even for X, which has one song that is included on two discography items). Removing channel="discography" doesn't make any impact.

     {if low_alphabet_heading}
         <h2>Songs that start with {low_alphabet_label}</h2>
            <li><a href="{url_title_path="songs"}">{title}</a></li>
            {if no_parents}{/if}
                <ul class="list-nav">
                {exp:playa:parents channel="discography"}
                        <li><a href="{path={channel_short_name}/{url_title}}">{title}</a></li>
        {if low_alphabet_footer}

The following works as expected

    {exp:channel:entries channel="lyrics" limit="50"}

            <li><a href="{url_title_path="songs"}">{title}</a></li>
                <ul class="list-nav">
                    <li><a href="{path={channel_short_name}/{url_title}}">{title}</a></li>


That code should work but you might want to use the var_prefix parameter to avoid variable name conflicts.

Also, because Low Alphabet is a plugin and EE's quirky template parser, you'll need to add parse="inward" to the opening low_alphabet:entries tag if you're using other tags inside it (as per the docs).

  • at this point the playa bit just outputs all songs associated with a discography entry - even for X which only has one song entry, it spits out the latest x discography entries. It's not targeting the "this" entry contained by the loop, but the channel itself as far as I can tell. – eru May 11 '14 at 6:20
  • Try adding entry_id="{entry_id}" to the playa:parents tag. But this is a Playa issue more than a LA one, really. – Low May 12 '14 at 7:56
  • Adding entry_id="{entry_id}" makes it so there are no results. I'll give pixel and tonic a ping. – eru May 13 '14 at 23:36
  • It does seem to be a LA issue. I'm honestly better off just running a SQL query based on url_segment and manually creating a menu embed if I can get the playa relationships working correctly sticking with a standard channel entries tag. – eru May 14 '14 at 0:16
  • Try adding parse="inward" to the opening LA tag. – Low May 14 '14 at 7:42
