function db_field_names in Zircon Profile 8

Same name and namespace in other branches
  1. 8.0 core/includes/database.inc \db_field_names()

Returns an array of field names from an array of key/index column specifiers.

This is usually an identity function but if a key/index uses a column prefix specification, this function extracts just the name.

Parameters

array $fields: An array of key/index column specifiers.

Return value

array An array of field names.

Deprecated

as of Drupal 8.0.x, will be removed in Drupal 9.0.0. Instead, get a database connection injected into your service from the container, get its schema driver, and call fieldNames() on it. E.g. $injected_database->schema()->fieldNames($fields);
