function FieldPluginBase::get_token_values_recursive in Views (for Drupal 7) 8.3

Recursive function to add replacements for nested query string parameters.

E.g. if you pass in the following array: array( 'foo' => array( 'a' => 'value', 'b' => 'value', ), 'bar' => array( 'a' => 'value', 'b' => array( 'c' => value, ), ), );

Would yield the following array of tokens: array( '%foo_a' => 'value' '%foo_b' => 'value' '%bar_a' => 'value' '%bar_b_c' => 'value' );

Parameters

$array: An array of values.

$parent_keys: An array of parent keys. This will represent the array depth.

Return value

An array of available tokens, with nested keys representative of the array structure.
