Custom Endpoint with Multiple Arguments/Parameters

I’ve developed a custom plugin for my project implementing several endpoints that take either no or one argument(s) and they are all working great.

Now I want to get a second parameter but if anything is wrong with the URL at all it will return a 404 so it becomes difficult to figure out what the exact problem is. Here is my latest attempt, which still returns 404:
```
add_action( 'rest_api_init', function () {
    register_rest_route( PLUGIN_NAMESPACE, '/v1/getstuff/(?P<slug>[a-z0-9\-]+)/(?P<secondparam>[a-z0-9\-]+)', array(
        'methods' => 'GET',
        'callback' => 'myFunctionToGetStuff',
    ));
});
```
How do I add additional parameters to a custom endpoint?

I’m not sure I follow. What request are you making?

Sorry. Let’s say my namespace is “myplugin” and my website is “example.com”. This would be an example request:

http://example.com/wp-json/myplugin/v1/getstuff/first-slug/second-slug

In my callback function I expect to be able to access (again referencing the example code from the first post) both arguments like this:
```
function myFunctionToGetStuff($data) {
    $firstSlug = $data['slug']; // in the above request would be "first-slug"
    $secondSlug = $data['secondparam']; //in the above request would be "second-slug"
}
```

Ok. Given the following code in a mu-plugin:
```
add_action( 'rest_api_init', function () {
    register_rest_route( 'myplugin', '/v1/getstuff/(?P<slug>[a-z0-9\-]+)/(?P<secondparam>[a-z0-9\-]+)', array(
        'methods' => 'GET',
        'callback' => 'myFunctionToGetStuff',
    ));
});

function myFunctionToGetStuff( $request ) {
	return array( 'hello world' );
}
```
When I do GET http://wordpress-develop.dev/wp-json/myplugin/v1/getstuff/first-slug/second-slug, I see:
```
[
"hello world"
]
```
If you’re getting a 404 with that request, then there’s something else going wrong in your codebase.

How do I add additional parameters to a custom endpoint?

Not sure what I was missing, but I have it sorted out now and working with multiple parameters. Thanks!

Do you have the final example you were using?

Hi Bachhuber,

I just using rest api v2, got route problem about document not clear at http://v2.wp-api.org/extending/adding/#arguments.
Can you improve docs about ‘/author/(?P<id>\d+)’ pattern ?
