Custom preview template for eZ content types

Implementing custom preview templates for eZ Publish content types is as easy as adding a new eZ view type in your content view configuration.

For every content type you wish to add the preview for, you need to define an override template for ngcb_preview view type, which will then automatically be used by the Content Browser to display the preview.

For example, to add the preview for your custom content type with identifier my_content_type, add the following config to your eZ Publish:

ezpublish:
    system:
        default:
            content_view:
                ngcb_preview:
                    my_content_type:
                        template: '@App/ngcb/preview/my_content_type.html.twig'
                        match:
                            Identifier\ContentType: my_content_type

@App/ngcb/preview/my_content_type.html.twig is then a regular eZ Publish content view template, meaning you have access to content and location variables, which you can use to render what ever you wish.
