Provide search query conditions.
Callback for hook_search_info().
This callback is invoked by search_view() to get an array of additional search conditions to pass to search_data(). For example, a search module may get additional keywords, filters, or modifiers for the search from the query string.
This example pulls additional search keywords out of the $_REQUEST variable, (i.e. from the query string of the request). The conditions may also be generated internally - for example based on a module's settings.
$keys: The search keywords string.
An array of additional conditions, such as filters.
function callback_search_conditions($keys) {
$conditions = array();
if (!empty($_REQUEST['keys'])) {
$conditions['keys'] = $_REQUEST['keys'];
}
if (!empty($_REQUEST['sample_search_keys'])) {
$conditions['sample_search_keys'] = $_REQUEST['sample_search_keys'];
}
if ($force_keys = config('sample_search.settings')
->get('force_keywords')) {
$conditions['sample_search_force_keywords'] = $force_keys;
}
return $conditions;
