Create Output Channel

Basic steps

• create a service tagged with name: dynamic_search.output_channel and a meaningful identifer
• register your service:

  opendxp_dynamic_search:
      context:
          default:
              output_channels:
                  my_output:
                      service: <your-identifer>

• your service must implement OpenDxp\Bundle\DynamicSearchBundle\OutputChannel\OutputChannelInterface
  • add your implementation in getQuery and getResult
  • optional: define options for your output channel

Example

config/services.yaml

services:
    App\DynamicSearch\OutputChannel\MyOutputChannel:
        tags:
            - { name: dynamic_search.output_channel, identifier: my_output_channel }

config/config.yaml

opendxp_dynamic_search:
  context:
      default:
          output_channels:
              my_output:
                  service: 'my_output_channel'
                  use_frontend_controller: true
                  options:
                      query_option: true
                      result_option: false
