To view records of database, we first need to get hold of a table using the TableRegistry class. We can fetch the instance out of registry using get() method. The get() method will take the name of the database table as argument.
Now, this new instance is used to find records from database using find() method. This method will return all records from the requested table.
Example
Make changes in the config/routes.php file as shown in the following code.
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('/pages',['controller'=>'Pages','action'=>'display', 'home']);
$builder->connect('/users', ['controller' => 'Users', 'action' => 'index']);
$builder->fallbacks();
});
Create a UsersController.php file at src/Controller/UsersController.php. Copy the following code in the controller file.
src/controller/UsersController.php
<?php
namespace App\Controller;
use App\Controller\AppController;
use Cake\ORM\TableRegistry;
use Cake\Datasource\ConnectionManager;
class UsersController extends AppController{
public function index(){
$users = TableRegistry::get('users');
$query = $users->find();
$this->set('results',$query);
}
}
?>
Create a directory Users at src/Template, ignore if already created, and under that directory create a View file called index.php. Copy the following code in that file.
src/Template/Users/index.ctp
<a href="add">Add User</a>
<table>
<tr>
<td>ID</td>
<td>Username</td>
<td>Password</td>
<td>Edit</td>
<td>Delete</td>
</tr>
<?php
foreach ($results as $row):
echo "<tr><td>".$row->id."</td>";
echo "<td<".$row-<username."</td>";
echo "<td>".$row->password."</td>";
echo "<td><a href='".$this-<Url->build(["controller" => "Users","action" => "edit",$row->id])."'>Edit</a></td>";
echo "<td><a href='".$this->Url->build(["controller" => "Users","action" => "delete",$row->id])."'>Delete</a></td></tr>";
endforeach;
?>
</table>

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.
