Simplified paginator which avoids potentially expensives queries to get the total count of records.
When using a simple paginator you will not be able to generate page numbers. Instead use only the prev/next pagination controls, and handle 404 errors when pagination goes past the available result set.

to modify which options/values can be set using request parameters.
array
$params Request params.
array
$settings The settings to merge with the request data.
array
Array of merged options.
paginate(object $object, array $params, array $settings)
Handles automatic pagination of model records.
When calling paginate()
you can use the $settings parameter to pass in pagination settings. These settings are used to build the queries made and control other pagination settings.
If your settings contain a key with the current table's alias. The data inside that key will be used. Otherwise the top level configuration will be used.
$settings = [ 'limit' => 20, 'maxLimit' => 100 ]; $results = $paginator->paginate($table, $settings);
The above settings will be used to paginate any repository. You can configure repository specific settings by keying the settings with the repository alias.
$settings = [ 'Articles' => [ 'limit' => 20, 'maxLimit' => 100 ], 'Comments' => [ ... ] ]; $results = $paginator->paginate($table, $settings);
This would allow you to have different pagination settings for Articles
and Comments
repositories.
By default CakePHP will automatically allow sorting on any column on the repository object being paginated. Often times you will want to allow sorting on either associated columns or calculated fields. In these cases you will need to define an allowed list of all the columns you wish to allow sorting on. You can define the allowed sort fields in the $settings
parameter:
$settings = [ 'Articles' => [ 'finder' => 'custom', 'sortableFields' => ['title', 'author_id', 'comment_count'], ] ];
Passing an empty array as sortableFields disallows sorting altogether.
You can paginate with any find type defined on your table using the finder
option.
$settings = [ 'Articles' => [ 'finder' => 'popular' ] ]; $results = $paginator->paginate($table, $settings);
Would paginate using the find('popular')
method.
You can also pass an already created instance of a query to this method:
$query = $this->Articles->find('popular')->matching('Tags', function ($q) { return $q->where(['name' => 'CakePHP']) }); $results = $paginator->paginate($query);
By using request parameter scopes you can paginate multiple queries in the same controller action:
$articles = $paginator->paginate($articlesQuery, ['scope' => 'articles']); $tags = $paginator->paginate($tagsQuery, ['scope' => 'tags']);
Each of the above queries will use different query string parameter sets for pagination data. An example URL paginating both results would be:
/dashboard?articles[page]=1&tags[page]=2
\Cake\Datasource\RepositoryInterface|\Cake\Datasource\QueryInterface

Cake\Core\Exception\Exception
validateSort(\Cake\Datasource\RepositoryInterface $object, array $options)
Validate that the desired sorting can be performed on the $object.
Only fields or virtualFields can be sorted on. The direction param will also be sanitized. Lastly sort + direction keys will be converted into the model friendly order key.
You can use the allowedParameters option to control which columns/fields are available for sorting via URL parameters. This helps prevent users from ordering large result sets on un-indexed values.
If you need to sort on associated columns or synthetic properties you will need to use the sortableFields
option.
Any columns listed in the allowed sort fields will be implicitly trusted. You can use this to sort on synthetic columns, or columns added in custom find operations that may not exist in the schema.
The default order options provided to paginate() will be merged with the user's requested sorting field/direction.
\Cake\Datasource\RepositoryInterface
$object Repository object.
array
$options The pagination options being used for this request.
array
An array of options with sort + direction removed and replaced with order if possible.
Runtime config
array
Whether the config property has already been configured with defaults
bool
Default pagination settings.
When calling paginate() these settings will be merged with the configuration you provide.
maxLimit
- The maximum limit users can choose to view. Defaults to 100limit
- The initial number of items per page. Defaults to 20.page
- The starting page, defaults to 1.allowedParameters
- A list of parameters users are allowed to set using request parameters. Modifying this list will allow users to have more influence over pagination, be careful with what you permit.array
