How to get the native Pods blocks to work in Archive templates?

Auto templates are for classic themes which do not have templates editable outside PHP, but might use the excerpt or archive description hooks.

For themes using Full Site Editing like TwentyTwentyFour, blocks Pods Single Item, Pods Field Value, Pods Single Item - List Fields, or Pods Related Item List can be used within the Query Loop block.

An Archive template already contains a loop for the archive query, viewable as the Query Loop block in the left List View sidebar. It usually contains default blocks like Title, Featured Image, and Post Meta.

Nothing will appear when the blocks are first inserted. To get started, write a template in the Custom Template field of the block options, following the syntax {@field_name} where field_name is a name of a custom field that has been defined on the post type, or any WordPress core column from the wp_posts table.

For example:

<p><a href="{@permalink}">{@post_title}</a></p>

See: docs.pods.io > Magic Tags

For more complex queries, one may also use a shortcode block with the Pods shortcode.

For an if statement if a file field exists, this template would be a start:

[if pdf_field]
  <a href="{@pdf_field}">
    <img src="https://picsum.photos/50" /> Download {@pdf_field.post_title}
  </a>
[/if]

Where:

• [if field_name] ... [/if] documentation can be found at docs.pods.io > IF/ELSE Conditional Tag.
• The field is named pdf_field of type File / Image.
• {@pdf_field} will output the URL to the file unless field settings are changed to output a full HTML link.
• {@pdf_field.post_title} will output the name of the file.

Thanks, Paul; I really appreciate you taking the time with this in-depth explanation!
Unfortunately, my dilemma remains for some reason. In the block editor, it looked promising and still looks great. I.e., different icons appear due to the “if-field-logic,” just as I expected. I have used the Pods Single Item block inside the Query Loop, as shown in the attached screenshot. For now, I also left the default Title block (until I get the Pods blocks working).

The code in the Custom Template field looks like this:

<style>
  img.latvalign {
  vertical-align: middle;
  float: right;
  }
</style>
<div style="padding-bottom: 5px;">
[if noter]
<img class="latvalign" src="https://olfm2.jansson-fam.se/wp-content/uploads/icons/musical_notes_icon.png" />
[/if]
[if inspelning]
<img class="latvalign" src="https://olfm2.jansson-fam.se/wp-content/uploads/icons/recording_icon.png" />
[/if]
[if lank]
<img class="latvalign" src="https://olfm2.jansson-fam.se/wp-content/uploads/icons/link_icon.png" />
[/if]
[if midi-fil]
<img class="latvalign" src="https://olfm2.jansson-fam.se/wp-content/uploads/icons/MIDI_icon.png" />
[/if]
</div>

Unfortunately, nothing of the Pods Custom Template is still visible on the frontend (only the ordinary Title Block), and of course, I am logged in as an administrator.

Do you have further suggestions on what I should check?

I vaguely remember having to change something in wp-config.php, but I can’t remember where I read that.

As I wrote, the pod templates work exactly as expected for individual posts, but unfortunately not for archives.
