I'm usign the module Paragraphs for Drupal 8. I need to print the raw value of a paragraph field in the twig template, so I'm trying to access to the value of the field in the hook_preprocess_field, but I don't know how to access the value in $variables.

Any idea?

You can use preprocess field hook which is supported in drupal 8 also . Example below:

function example_preprocess_field(&$variables) {
    if (($variables['element']['#field_name'] == 'example')) {
    //get the value of the field
    // add a class to the field        
    $variables['attributes']['class'] = [
  • dsm function needs devel module, so before running this code install that module. Commented Sep 7, 2016 at 16:25
  • Thank you for your replies. But I don't know why when I print the content of the array in the hook_preprocess_field, the value of that field is not present. Maybe because it is part of a paragraph field, I don't know. I could achieve what I needed using the variable paragraph instead of content in the twig template like in drupal.org/node/2662400 where it describes exactly the same scenario I have.

  • Yes, the values of paragraph fields are in the variable paragraph, but not in field.html.twig, but in paragraph.html.twig.

To get at the value of a paragraphs field for manipulation etc you can use template_preprocess_paragraph(&$variables) or more specifically template_preprocess_paragraph__PARAGRAPH_TYPE(&$variables)


One Good solution for that is to first install Devel module and then you can use dsm function.

this function is easy to use just write dsm($variables) and it will print a hierarchical form of element.

Using that you will know how to have access to your desired values and fields.
