1. 2.x src/BackgroundImageFormTrait.php \Drupal\background_image\BackgroundImageFormTrait::mapStatesConditions()
2. 2.0.x src/BackgroundImageFormTrait.php \Drupal\background_image\BackgroundImageFormTrait::mapStatesConditions()

Recursively maps a selector for a set of #states conditions.

Parameters

string $selector: The real DOM selector that should be used in the #states conditions.

array $conditions: A standard States API conditions array. In place of a condition selector, you can use "%selector" anywhere and it will be replaced with the real $selector value above. An example of what this real selector value would be is if an element's #parents value contained an array with the values ['parent', 'child', 'input_element'], then the corresponding selector would be "edit-parent-child-input-selector". In most cases, you can pass "*" as the whole selector which will turn into the following selector: "[data-drupal-selector="%selector"]".

Return value

array The newly mapped #states conditions.
