function template_preprocess_filter_tips

Prepares variables for filter tips templates.

Default template: filter-tips.html.twig.

Parameters

array $variables: An associative array containing:

• tips: An array containing descriptions and a CSS ID in the form of 'module-name/filter-id' (only used when $long is TRUE) for each filter in one or more text formats. Example:

[
    'Full HTML' => [
        0 => [
            'tip' => 'Web page addresses and email addresses turn into links automatically.',
            'id' => 'filter/2',
        ],
    ],
];

• long: (optional) Whether the passed-in filter tips contain extended explanations, i.e. intended to be output on the path 'filter/tips' (TRUE), or are in a short format, i.e. suitable to be displayed below a form element. Defaults to FALSE.
