abstract class ArgumentPluginBase in Zircon Profile 8

Same name and namespace in other branches
  1. 8.0 core/modules/views/src/Plugin/views/argument/ArgumentPluginBase.php \Drupal\views\Plugin\views\argument\ArgumentPluginBase

Base class for argument (contextual filter) handler plugins.

The basic argument works for very simple arguments such as nid and uid

Definition terms for this handler:

  • name field: The field to use for the name to use in the summary, which is the displayed output. For example, for the node: nid argument, the argument itself is the nid, but node.title is displayed.
  • name table: The table to use for the name, should it not be in the same table as the argument.
  • empty field name: For arguments that can have no value, such as taxonomy which can have "no term", this is the string which will be displayed for this lack of value. Be sure to use $this->t().
  • validate type: A little used string to allow an argument to restrict which validator is available to just one. Use the validator ID. This probably should not be used at all, and may disappear or change.
  • numeric: If set to TRUE this field is numeric and will use %d instead of %s in queries.
