PHP Class yii\data\Sort

When data needs to be sorted according to one or several attributes, we can use Sort to represent the sorting information and generate appropriate hyperlinks that can lead to sort actions. A typical usage example is as follows, ~~~ function actionIndex() { $sort = new Sort([ 'attributes' => [ 'age', 'name' => [ 'asc' => ['first_name' => SORT_ASC, 'last_name' => SORT_ASC], 'desc' => ['first_name' => SORT_DESC, 'last_name' => SORT_DESC], 'default' => SORT_DESC, 'label' => 'Name', ], ], ]); $models = Article::find() ->where(['status' => 1]) ->orderBy($sort->orders) ->all(); return $this->render('index', [ 'models' => $models, 'sort' => $sort, ]); } ~~~ View: ~~~ display links leading to sort actions echo $sort->link('name') . ' | ' . $sort->link('age'); foreach ($models as $model) { display $model here } ~~~ In the above, we declare two [[attributes]] that support sorting: name and age. We pass the sort information to the Article query so that the query results are sorted by the orders specified by the Sort object. In the view, we show two hyperlinks that can lead to pages with the data sorted by the corresponding attributes. Afficher le fichier Open project: yiisoft/yii2 Class Usage Examples

Свойство	Type	Description
$attributes		list of attributes that are allowed to be sorted. Its syntax can be described using the following example: php [ 'age', 'name' => [ 'asc' => ['first_name' => SORT_ASC, 'last_name' => SORT_ASC], 'desc' => ['first_name' => SORT_DESC, 'last_name' => SORT_DESC], 'default' => SORT_DESC, 'label' => 'Name', ], ] In the above, two attributes are declared: age and name. The age attribute is a simple attribute which is equivalent to the following: php 'age' => [ 'asc' => ['age' => SORT_ASC], 'desc' => ['age' => SORT_DESC], 'default' => SORT_ASC, 'label' => Inflector::camel2words('age'), ] The name attribute is a composite attribute: - The name key represents the attribute name which will appear in the URLs leading to sort actions. - The asc and desc elements specify how to sort by the attribute in ascending and descending orders, respectively. Their values represent the actual columns and the directions by which the data should be sorted by. - The default element specifies by which direction the attribute should be sorted if it is not currently sorted (the default value is ascending order). - The label element specifies what label should be used when calling Sort::link to create a sort link. If not set, [[Inflector::camel2words()]] will be called to get a label. Note that it will not be HTML-encoded. Note that if the Sort object is already created, you can only use the full format to configure every attribute. Each attribute must include these elements: asc and desc.
$defaultOrder		the order that should be used when the current request does not specify any order. The array keys are attribute names and the array values are the corresponding sort directions. For example, php [ 'name' => SORT_ASC, 'created_at' => SORT_DESC, ]
$enableMultiSort		whether the sorting can be applied to multiple attributes simultaneously. Defaults to false, which means each time the data can only be sorted by one attribute.
$params		parameters (name => value) that should be used to obtain the current sort directions and to create new sort URLs. If not set, $_GET will be used instead. In order to add hash to all links use array_merge($_GET, ['#' => 'my-hash']). The array element indexed by [[sortParam]] is considered to be the current sort directions. If the element does not exist, the [[defaultOrder|default order]] will be used.
$route		the route of the controller action for displaying the sorted contents. If not set, it means using the currently requested route.
$separator		the character used to separate different attributes that need to be sorted by.
$sortParam		the name of the parameter that specifies which attributes to be sorted in which direction. Defaults to sort.
$urlManager		the URL manager used for creating sort URLs. If not set, the urlManager application component will be used.
