属性详情

the zero-based index of the current page. Defaults to 0.

total number of items. Defaults to 0.

the limit of the data. This may be used to set the LIMIT value for a SQL statement for fetching the current page of data. This returns the same value as pageSize.

the offset of the data. This may be used to set the OFFSET value for a SQL statement for fetching the current page of data.

number of pages

number of items in each page. Defaults to 10.

name of the GET variable storing the current page index. Defaults to 'page'.

of parameters (name=>value) that should be used instead of GET when generating pagination URLs. Defaults to null, meaning using the currently available GET parameters.

the route (controller ID and action ID) for displaying the paged contents. Defaults to empty string, meaning using the current route.

whether to ensure currentPage is returning a valid page number. When this property is true, the value returned by currentPage will always be between 0 and (pageCount-1). Because pageCount relies on the correct value of itemCount, it means you must have knowledge about the total number of data items when you want to access currentPage. This is fine for SQL-based queries, but may not be feasible for other kinds of queries (e.g. MongoDB). In those cases, you may set this property to be false to skip the validation (you may need to validate yourself then). Defaults to true.

方法详情

Constructor.

Applies LIMIT and OFFSET to the specified query criteria.

Creates the URL suitable for pagination. This method is mainly called by pagers when creating URLs used to perform pagination. The default implementation is to call the controller's createUrl method with the page information. You may override this method if your URL scheme is not the same as the one supported by the controller's createUrl method.
