# how to get the raw field value in a twig template?

{{ entity.field_name.value }} to get the true raw value, includes tags and encoding.

    Example: {{ node.body.value }}
    result: <p>Batman &amp; Robin</p>

{{ content.field_name.0 }} to get the raw value minus tags and encoding.

    Example: {{ content.body.0 }}
    result: Batman & Robin

## with Twig Field Value module
{{ content.field_name|field_value }}

# How to trim body text (field_body)

## 1. Use |raw to output the html as html, may produce malformed tags:

{% set text = content.field_body|render %}
{{ text|length > 200 ? text|slice(0, 200)|raw ~ '...' : text|raw }}

## 2. Strip html first, cleaner:

{% set text = content.field_body|render|striptags %}
{{ text|length > 200 ? text|slice(0, 200) ~ '...' : text }}


# Check if field is empty
{% if content.field_name %}

## OR, if there is some unexpected output then this:

{% if content.field_name|render is not empty %}
  {% content.field_name %}
{% endif %}

## manual image style
{% for item in content.field_card_image['#items'] %}
  {% set image = {
    '#theme':      'image_style',
    '#style_name': 'medium',
    '#uri':        item.entity.uri.value,
    '#alt':        item.alt,
    '#width':      item.width,
    '#height':     item.height
  } %}
  {{ image }}
{% endfor %}
