Pass Request through Laravel Routes

Watch "Pass Request Data to View" on Laracastsopen in new window

Retrieving Request Data

We have previously learned that data passed through the URL or query string is stored by PHP in the $_GETopen in new window variable. In Laravel, the requestopen in new window help function is used instead.

Route::get('/', function () {
  /* /?name=John */
  $name = request('name'); // John

  return view('home');
});

Sending Data to the View

An array of data may be passed to viewsopen in new window. When doing this, the array of data must be an associative array, with key / value pairs. The array is added as the optional argument to the view helper function.

Route::get('/', function () {
  /* /?name=John */
  $name = request('name'); // John

  return view('home', ["name" => $name]);
});

Inside the view, each value can be access using its corresponding key. A variable with the same name as the key will be accessible in the view.

<html>
  <body>
    <h1>Hello, <?php echo $name; ?></h1>
  </body>
</html>

Of course, "echoing" data directly received from a user is an unsafe practice as could leave your site vulnerable to attack. That is why is better to use Blade to display the dataopen in new window.

<html>
  <body>
    <h1>Hello, {{ $name }}</h1>
  </body>
</html>
