How do you handle form submissions in Slim Framework?
To handle form submissions in Slim Framework, follow these steps:
Step 1: Set up a POST route
Create a route to handle the form submission using the post()
method in Slim.
Example
<?php
use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
use Slim\Factory\AppFactory;
require __DIR__ . '/vendor/autoload.php';
$app = AppFactory::create();
// Define a route to show the form
$app->get('/form', function (Request $request, Response $response) {
$form = '<form method="POST" action="/submit">
<input type="text" name="name" placeholder="Your Name">
<button type="submit">Submit</button>
</form>';
$response->getBody()->write($form);
return $response;
});
// Define a POST route to handle form submission
$app->post('/submit', function (Request $request, Response $response) {
// Retrieve form data
$data = $request->getParsedBody();
$name = $data['name'] ?? 'Guest';
// Return a response
$response->getBody()->write("Hello, " . htmlspecialchars($name));
return $response;
});
$app->run();
?>
Step 2: Access Form Data
When the form is submitted, Slim retrieves the form data via $request->getParsedBody()
. This method returns an associative array of form inputs. Use it to process the data as needed.
Step 3: Run and Test
Start your Slim app and test the form submission.
