- you're done!
- </p>
-
- <p>
- If not, you will need to add the component as a module to your
- application. Add the entry <code>'Zend\Mvc\Plugin\Prg'</code> to
- your list of modules in your application configuration (typically
- one of <code>config/application.config.php</code> or
- <code>config/modules.config.php</code>).

- <h2>Usage</h2>
-
- <p>
- When a user sends a POST request (e.g. after submitting a form), their
- browser will try to protect them from sending the POST again, breaking
- the back button, causing browser warnings and pop-ups, and sometimes
- reposting the form. Instead, when receiving a POST, we should store the
- data in a session container and redirect the user to a GET request.
- </p>
-
- <p>This plugin can be invoked with two arguments:</p>
-
- <ul>
- <li><code>$redirect</code>, a string containing the redirect location,
- which can either be a named route or a URL, based on the contents of
- the second parameter.</li>
- <li><code>$redirectToUrl</code>, a boolean that when set to
- <code>TRUE</code>, causes the first parameter to be treated as a URL
- instead of a route name (this is required when redirecting to a URL
- instead of a route). This argument defaults to <code>FALSE</code>.</li>
- </ul>
-
- <p>When no arguments are provided, the current matched route is used.</p>
-
- <h3>Example Usage</h3>
-
- <pre><code class="lang-php" data-trim>
-// Pass in the route/url you want to redirect to after the POST
-$prg = $this->prg('/user/register', true);
-
-if ($prg instanceof \Zend\Http\PhpEnvironment\Response) {
- // Returned a response to redirect us.
- return $prg;
-}
-
-if ($prg === false) {
- // This wasn't a POST request, but there were no params in the flash
- // messenger; this is probably the first time the form was loaded.
- return ['form' => $myForm];
-}
-
-// $prg is an array containing the POST params from the previous request
-$form->setData($prg);
-
-// ... your form processing code here
- </code></pre>
- </div>
