[FIXED] CakePHP redirect with form parameter

Issue

In CakePHP 3.1 I am redirecting to login page after a database update and I want to pass back the email so that form input is already populated.

I can do it the standard way with using the controller and action in the redirect.

Instead I am using just a url string

return $this->redirect('/login',['?' => ['email' => $email]]);

This gives me the error Unknown status code

Solution

The redirect method expects a status code as the second parameter. You will need to provide and array-based URL as the first parameter or append the query var to the current string.

return $this->redirect('/login?email=' . $email);

return $this->redirect([ 'controller' => 'Users', 'action' => 'login', '?' => [ 'email' => $email ] ]);
