[How to include Drupal 8 & 9 webform values in confirmation etc emails]

howto.md

In the email subject use:

• [webform_submission:values:YOUR_FIELD_KEY].
  If you don't want a label to appear, you need to add :no_label
• [webform_submission:values:YOUR_FIELD_KEY:no_label]
• If the value is a field in a fieldset, use [webform_submission:values:YOUR_FIELDSET_FORM_KEY:YOUR_FIELD_KEY].
  (For more details, look at the webform tokens)

In the Email handler's custom Twig template:

• {{ data.YOUR_FIELD_KEY }}
  (For more info, look at the "HELP USING TWIG") section.

If you'd like to output a nice list of labels and values for all filled-out fields, you can use the following:

{% for key, value in data %} 
  {% if webform_token('[webform_submission:values:' ~ key ~ ']', webform_submission) %}
    {{ webform_token('[webform:element:' ~ key ~ ']', webform) }}: {{ webform_token('[webform_submission:values:' ~ key ~ ']', webform_submission) }}
  {% endif %}
{% endfor %}

with formatting:

<p><b><u>Submitted Data</u></b></p>
{% for key, value in data %} 
  {% if webform_token('[webform_submission:values:' ~ key ~ ']', webform_submission) %}
    <p><b>{{ webform_token('[webform:element:' ~ key ~ ']', webform) }}</b>: <br>
    {{ webform_token('[webform_submission:values:' ~ key ~ ']', webform_submission) }}</p>
  {% endif %}
{% endfor %}
