Post/Redirect/Get plugin for zend-mvc controllers.
$ composer require zendframework/zend-mvc-plugin-prgInstall via composer:
$ composer require zendframework/zend-mvc-plugin-prg
If you are using the zend-component-installer, you're done!
If not, you will need to add the component as a module to your
application. Add the entry 'Zend\Mvc\Plugin\Prg' to
your list of modules in your application configuration (typically
one of config/application.config.php or
config/modules.config.php).
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.
This plugin can be invoked with two arguments:
$redirect, a string containing the redirect location,
which can either be a named route or a URL, based on the contents of
the second parameter.$redirectToUrl, a boolean that when set to
TRUE, 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 FALSE.When no arguments are provided, the current matched route is used.
// 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
