public function FieldPluginBase::postRender in Drupal 8

Same name and namespace in other branches

1. 9 core/modules/views/src/Plugin/views/field/FieldPluginBase.php \Drupal\views\Plugin\views\field\FieldPluginBase::postRender()

Runs after every field has been rendered.

This is meant to be used mainly to deal with field handlers whose output cannot be cached at row level but can be cached at display level. The typical example is the row counter. For completely uncacheable field output placeholders should be used.

Parameters

\Drupal\views\ResultRow $row: An array of all ResultRow objects returned from the query.

$output: The field rendered output.

Return value

string[] An associative array of post-render token values keyed by placeholder.

Overrides FieldHandlerInterface::postRender
