Question

There is some solution for using CakePHP route with params only when are not empty?

Now I code below, but I would like some better:

if(Configure::read('Config.language') !== 'en') { // en is default language
    $language = '/:language';
} else {
    $language = '';
}

Router::connect($language .'/'. __('register', true), array(
    'controller' => 'users',
    'action' => 'register'));

This code works perfectly, but I still must set language in AppHelper by url() method.

In older apps I was always duplicate Router::connect:

Router::connect('/:language/'. __('register', true), array(
    'controller' => 'users',
    'action' => 'register')); // for all languages without default language
Router::connect('/'. __('register', true), array(
    'controller' => 'users',
    'action' => 'register')); // only for default language (en)

Maybe there is simplest solutions?

Answer 1

You need to use 2 routes but add the ‘persist’ option for your language based routes. Adding ‘persist’ will avoid having to specify ‘language’ key each time when generating urls.

// for all languages without default language. 
Router::connect(
    '/:lang/'. __('register', true),
    array(
        'controller' => 'users', 
        'action' => 'register'
    ), 
    array(
        'persist' => array('lang')
    )
);

// only for default language (en)
Router::connect(
    '/'. __('register', true),
    array(
        'controller' => 'users', 
        'action' => 'register'
    )
);
