If we want to show a set of data that is huge, we can use pagination and this feature is available with cake php 4 which is very easy to use.
We have a table titled “articles” with following data −
Let us use pagination to display the data in the form of pages, instead of showing them all together.
Example
Make Changes in the config/routes.php file as shown in the following program.
config/routes.php
<?php use CakeHttpMiddlewareCsrfProtectionMiddleware; use CakeRoutingRouteDashedRoute; use CakeRoutingRouteBuilder; $routes->setRouteClass(DashedRoute::class); $routes->scope(''/'', function (RouteBuilder $builder) { $builder->registerMiddleware(''csrf'', new CsrfProtectionMiddleware([ ''httpOnly'' => true, ])); $builder->applyMiddleware(''csrf''); //$builder->connect(''/pages'',[''controller''=>''Pages'',''action''=>''display'', ''home'']); $builder->connect(''posts'',[''controller''=>''Posts'',''action''=>''index'']); $builder->fallbacks(); });
Create a PostsController.php file at src/Controller/PostsController.php. Copy the following code in the controller file. Ignore, if already created.
src/Controller/PostsController.php
<?php namespace AppController; use AppControllerAppController; class PostsController extends AppController { public function index(){ $this->loadModel(''articles''); $articles = $this->articles->find(''all'')->order([''articles.id ASC'']); $this->set(''articles'', $this->paginate($articles, [''limit''=> ''3''])); } } ?>
The data from articles table is fetched using −
$this->loadModel(''articles''); $articles = $this->articles->find(''all'')->order([''articles.id ASC'']);
To apply pagination and we would show the data with 3 per records and the same is done as follows −
$this->set(''articles'', $this->paginate($articles, [''limit''=> ''3'']));
This is enough to activate pagination on the articles tables.
Create a directory Posts at src/Template and under that directory create a Viewfile called index.php. Copy the following code in that file.
src/Template/Posts/index.php
<div> <?php foreach ($articles as $key=>$article) {?> <a href="#"> <div> <p><?= $article->title ?> </p> <p><?= $article->details ?></p> </div> </a> <br/> <?php } ?> <ul class="pagination"> <?= $this->Paginator->prev("<<") ?> <?= $this->Paginator->numbers() ?> <?= $this->Paginator->next(">>") ?> </ul> </div>
The pagination for the list of pages is done as follows −
<ul class="pagination"> <?= $this->Paginator->prev("<<") ?> <?= $this->Paginator->numbers() ?> <?= $this->Paginator->next(">>") ?> </ul>
Execute the above example by visiting the following URL −
http://localhost/cakephp4/posts
Output
When you run the code, you will see the following output −
Click on the numbers below, to switch to next page, or use the next or previous button.
For example
You will see that page=2 is appended to the page url in the browser.
