Certain parts of the web pages are repeated on multiple web pages, but at different locations. CakePHP can help us reuse these repeated parts. These reusable parts are called Elements - help box, extra menu, etc. An element is basically a mini-view. We can also pass variables in elements.
Cake\View\View::element(string $elementPath, array $data, array $options =[]
There are three arguments to the above function as follows ?
The first argument is the name of the template file in the /src/Template/element/ folder.
The second argument is the array of data to be made available to the rendered view.
The third argument is for the array of options. e.g. cache.
Out of the 3 arguments, the first one is compulsory, while the rest are optional.
Example
Create an element file at src/Template/element directory called helloworld.php. Copy the following code in that file.
src/Template/element/helloworld.php
<p>Hello World</p>
Create a folder Elems at src/Template and under that directory create a View file called index.php. Copy the following code in that file.
src/Template/Elems/index.php
Element Example: <?php echo $this->element('helloworld'); ?>
Make Changes in the config/routes.php file as shown in the following program.
config/routes.php
<?php
use Cake\Http\Middleware\CsrfProtectionMiddleware;
use Cake\Routing\Route\DashedRoute;
use Cake\Routing\RouteBuilder;
$routes->setRouteClass(DashedRoute::class);
$routes->scope('/', function (RouteBuilder $builder) {
$builder->registerMiddleware('csrf', new CsrfProtectionMiddleware([
'httpOnly' => true,
]));
$builder->applyMiddleware('csrf');
$builder->connect('/element-example',['controller'=>'Elems','action'=>'index']);
$builder->fallbacks();
});
Create an ElemsController.php file at src/Controller/ElemsController.php. Copy the following code in the controller file.
src/Controller/ElemsController.php
<?php
namespace App\Controller;
use App\Controller\AppController;
class ElemsController extends AppController{
public function index(){
}
}
?>
Execute the above example by visiting the following URL http://localhost/cakephp4/element-example
Output
Upon execution, the above URL will give you the following output.

How do I embed PHP code in an HTML file?
Jun 22, 2025 am 01:00 AM
You can embed PHP code into HTML files, but make sure that the file has an extension of .php so that the server can parse it correctly. Use standard tags to wrap PHP code, insert dynamic content anywhere in HTML. In addition, you can switch PHP and HTML multiple times in the same file to realize dynamic functions such as conditional rendering. Be sure to pay attention to the server configuration and syntax correctness to avoid problems caused by short labels, quotation mark errors or omitted end labels.
What are the best practices for writing clean and maintainable PHP code?
Jun 24, 2025 am 12:53 AM
The key to writing clean and easy-to-maintain PHP code lies in clear naming, following standards, reasonable structure, making good use of comments and testability. 1. Use clear variables, functions and class names, such as $userData and calculateTotalPrice(); 2. Follow the PSR-12 standard unified code style; 3. Split the code structure according to responsibilities, and organize it using MVC or Laravel-style catalogs; 4. Avoid noodles-style code and split the logic into small functions with a single responsibility; 5. Add comments at key points and write interface documents to clarify parameters, return values ??and exceptions; 6. Improve testability, adopt dependency injection, reduce global state and static methods. These practices improve code quality, collaboration efficiency and post-maintenance ease.
