You just need to set the has_archive parameter to true or your chosen slug when registering the post type.

add_action( 'init', 'question_10706_init' );

function question_10706_init() {

    register_post_type( 'example', array(
        'labels' => array(
            'name' => __('Examples'),
            'singular_name' => __('Example')
            ),
        'public' => true,
        'show_ui' => true,
        'rewrite' => array(
            'slug' => 'example',
            'with_front' => false
            ),
        //'has_archive' => true // Will use the post type slug, ie. example
        //'has_archive' => 'my-example-archive' // Explicitly setting the archive slug
    ) );

}

• True - The archive url uses the post type slug
  Eg. www.example.com/example/
• Explicit - Use whichever slug you've provided
  Eg. www.example.com/my-example-archive/

Next visit the permalink page, doing this will regenerate the rewrite rules, accounting for the new post type archive.

Next create an archive-{$post_type}.php template to handle that archive (it could be a straight copy->paste of your existing archive, make adjustments as necessary). {$post_type} would represent the name of your actual post type.

Yes, you'll just need to set the has_archive parameter to true or your chosen slug when registering your custom post type.

So firstly add the has_archive parameter to your post type, here's an example...

add_action( 'init', 'question_10706_init' );

function question_10706_init() {

    register_post_type( 'example', array(
        'labels' => array(
            'name' => __('Examples'),
            'singular_name' => __('Example')
            ),
        'public' => true,
        'show_ui' => true,
        'rewrite' => array(
            'slug' => 'example',
            'with_front' => false
            ),
        //'has_archive' => true // Will use the post type slug, ie. example
        //'has_archive' => 'my-example-archive' // Explicitly setting the archive slug
    ) );

}

The has_archive parameter supports the following settings.

1. false (default)

No archive

2. true

The archive url is formulated from the post type slug

www.example.com/example/

3. 'string'

The archive url is explicitly set to the slug you provided

www.example.com/my-example-archive/

Once you've added the parameter visit the permalink page, this will cause a regeneration of the rewrite rules, accounting for the custom post type archive.

Lastly, create an archive-{$post_type}.php template to handle that archive (it could be a straight copy->paste of your existing archive, make adjustments as necessary).
Noting, that {$post_type} would of course represent the slug of your actual post type.
