Introduction

When working with Drupal, it's not uncommon to encounter situations where you need to access the URL and description of file field items in a node template. This can be particularly challenging when dealing with multiple file fields, such as in the case of the publication content type. In this article, we'll explore how to get the URL and description of file field items in a node template, specifically for the node--publication.html.twig template.

Understanding FileFieldItemList

Before we dive into the solution, it's essential to understand what FileFieldItemList is. FileFieldItemList is a Drupal API that represents a list of file fields. It's a collection of file field items, each of which contains information about a file, such as its URL, description, and more.

Accessing FileFieldItemList in Node Template

To access the FileFieldItemList in a node template, you can use the file_entity module, which provides a set of APIs for working with file fields. In the node--publication.html.twig template, you can access the FileFieldItemList using the file_entity module's file_entity function.

Here's an example of how you can access the FileFieldItemList in the node--publication.html.twig template:

{% for file in file_entity('field_file_1') %}
  {{ file.url }}
  {{ file.description }}
{% endfor %}

In this example, field_file_1 is the name of the file field in the publication content type. The file_entity function returns a FileFieldItemList object, which we can then iterate over using a for loop.

Getting the URL and Description of FileFieldItemList's Items

Now that we have the FileFieldItemList object, we can access the URL and description of each file field item using the url and description properties, respectively.

Here's an example of how you can get the URL and description of each file field item:

{% for file in file_entity('field_file_1') %}
  <p>
    <a href="{{ file.url }}">{{ file.description }}</a>
  </p>
{% endfor %}

In this example, we're using the url property to get the URL of each file field item and the description property to get the description of each file field item.

Tips and Variations

Here are a few tips and variations to keep in mind when working with FileFieldItemList in a node template:

Multiple file fields: If you have multiple file fields in your content type, you can access each file field using the file_entity function, just like in the example above.
File field item properties: In addition to the url and description properties, you can also access other properties of each file field item, such as the filename, filesize, and filemime.
File field item rendering: If you want to render each file field item as a link, you can use the link function to create a link to the file.

Conclusion

In this article, we've explored how to get the URL and description of file field items in a node template, specifically for the node--publication.html.twig template. We've used the file_entity module's file_entity function to access the FileFieldItemList object and then iterated over the object to access the URL and description of each file field item. With these tips and variations, you should be able to access the URL and description of file field items in your node templates with ease.
