3. 10 core/modules/views/src/Plugin/views/field/FieldPluginBase.php \Drupal\views\Plugin\views\field\FieldPluginBase::getTokenValuesRecursive()

Recursive function to add replacements for nested query string parameters.

E.g. if you pass in the following array: [ 'foo' => [ 'a' => 'value', 'b' => 'value', 'c.d' => 'invalid value', '&invalid' => 'invalid value', ], 'bar' => [ 'a' => 'value', 'b' => [ 'c' => value, ], ], ];

Would yield the following array of tokens: [ '{{ arguments.foo.a }}' => 'value', '{{ arguments.foo.b }}' => 'value', '{{ arguments.bar.a }}' => 'value', '{{ arguments.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

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