Symfony 2.0 - How to create route with array-parameters?

问题

I want to create a route, that matches on an array.

example:

    Name_show:
        pattern:  /Name/{names}
        defaults: { _controller: testBundle:Name:showNames }

where {names} holds an array of names, like:

array([1] => 'Thomas', [2] => 'Anton', [3] => 'Berta');

How to handle this? Symfony 2.0 responses with

Warning: preg_match() expects parameter 2 to be string, array given

can't find any solution in symfony doc.

回答1:

You can use it as a string and just serialize() the content before and after.

As far as I know symfony2 doesn't allow arrays in routing, how would the URL Look with an array in? A URL has to be a string, so serializing the array and passing it as a string is probably a better option.

回答2:

I agree with @JamesHalsall about serializing. I would also add that the serialized string should then be urlencoded before being used as a GET parameter.

回答3:

You have to validate the route, so either use some contrived event handling (see the kernel.controller event ) or use a controller that simply redirects to a new URL if the Name is in the array or displays an error page.

Also you could experiment with the ChainRouter that is a replacement for the default Symfony2 router (supports Doctrine-based routing and such).
