Wie schreibe ich in Zweig Vorlage Ansicht?

Question

PHP-Code für Drupal 7:

<?php foreach ($rows as $row_number => $columns): ?> 
    <?php foreach ($columns as $column_number => $item): ?> 
     <?php print $item; ?> 
    <?php endforeach; ?> 
<?php endforeach; ?> 

Ich schrieb dies, aber ich bin immer Fehler in Drupal 8. Code:

{% foreach row_number, columns in rows %} 
    {% foreach column_number, item in columns %} 
     {{ item }} 
    {% endforeach %} 
{% endforeach %}

Answer 1

Verwendung for in Zweig statt foreach

{% for row_number, columns in rows %} 

    {% for column_number, item in columns %} 

     {{ item }} 

    {% endfor %} 

{% endfor %}
