* This is a like smarty function. It sets a thumb button link that allows you to like (and unlike) an object. It also
|
|
* provides a count of likes thus far on that particular object.
|
|
* @param $params
|
|
* - type - sets the type of object being liked. Ex: trackeritem, wiki, article, etc
|
|
* - object - sets the id of the object being liked.
|
|
* - count_label - default "Likes" - sets the label after the count. Ex: "recommendations" would show "54 recommendations" instead of |Likes"
|
|
* - count_only - default 'false' - sets whether to only show the count.
|
|
*
|
|
* @param $smarty
|
|
* @return string|void
|
|
* @throws Exception
