Meta Box

Thanks!

I've worked this out myself. For benefit of others, make the field cloneable.

That was this listings view.

And this is the single view:

Views Screen (singular)

Thanks for all your help on this, but it is still not working for me... The twig is not rendering at all.

Here is the source code of the rendered page:

<table>
<tr>
        <th></th>
        <th>Date</th>
        <th>Title</th>
        <th>Location</th>
    </tr>
    
        <tr>
            <!-- not live so don't want to share URL publicly -->
            <!-- but this produces the URL of the listing page itself, not a link to the item page -->
            <td><a href="https://mysite.url/print-editions/">Detail</a>
            </td>
            <td><!--blank--></td>       
            <td><!-- should render {{ post.year }}</td>
            <td><!-- should render {{ post.booktitle }} -- a custom field called 'booktitle' rather than the name of the post --></td>
            <td><!-- should render {{ post.location }}--></td>  
       </tr>
    </table>

I can provide the PHP for the post type or field group, if it helps...

I have followed this suggestion, with no output.

But I think I need a bit more explanation.

This code was intended for a view, editions-list, that lists not all posts, but only custom post type, "edition" each of which represents a post about a book. I've created this using MetaBox.

editions-list looks something like this (I've only given the first few fields):

<table>
<tr>
<th></th>
<th>Date</th>
<th>Title</th>
</tr>

{% for post in query.posts %}
<tr>
<td>Detail</td>
<td>{{ post.year }}</td>
<td>{{ post.booktitle }}</td>
</tr>
{% endfor %}
</table>

Type for editions-list is archive.
Location for editions-list is edition Archive.

I then have created a second view, single-book-view, that gives a detailed view of each book.

single-book-view looks something like this (I've only given the first few fields):

<table>
   <tr>
     <td>Year</td>
     <td>{{ post.year }}</td>
   </tr>
   <tr>
      <td>Title</td>
      <td>{{ post.booktitle }}</td>
    </tr>
  </table>

Type for single-book-view is singular.
Location for single-book-view is edition / all
