Lack of interest Random resources (order clause)

[cclaerhout]

Could you please add a random option to set the resources order inside the "getResources" function from the resources model (like you did for feature resources)? It will be useful for widgets.

Example:

Search:

$orderClause = $this->prepareResourceOrderOptions($fetchOptions, 'resource.last_update DESC');

Replace with

    if (!empty($fetchOptions['order']) && $fetchOptions['order'] == 'random')
     {
       $orderClause = 'ORDER BY RAND()';
     }
     else
     {
       $orderClause = $this->prepareResourceOrderOptions($fetchOptions, 'resource.last_update DESC');
     }
