# `PhoenixKitWeb.Helpers.MediaSelectorHelper`
[🔗](https://github.com/BeamLabEU/phoenix_kit/blob/v1.7.165/lib/phoenix_kit_web/helpers/media_selector_helper.ex#L1)

Helper functions for integrating the media selector component.

Provides convenience functions to generate media selector URLs,
parse returned selections, and handle media selector integration
from any LiveView or controller.

## Examples

    # In a LiveView template
    <.link navigate={MediaSelectorHelper.media_selector_url(@current_path, mode: :single)}>
      Select Featured Image
    </.link>

    # In handle_params to receive selection
    def handle_params(params, _uri, socket) do
      case MediaSelectorHelper.parse_selected_media(params) do
        {:ok, [file_uuid]} ->
          socket
          |> assign(:featured_image_uuid, file_uuid)
          |> put_flash(:info, "Image selected!")

        {:ok, file_uuids} ->
          socket
          |> assign(:gallery_uuids, file_uuids)
          |> put_flash(:info, "#{length(file_uuids)} images selected!")

        :none ->
          socket
      end
    end

# `get_first_selected`

Extracts the first file UUID from selected media.

Useful for single-selection scenarios where you only need one file UUID.

## Examples

    get_first_selected(%{"selected_media" => "id1,id2,id3"})
    #=> {:ok, "id1"}

    get_first_selected(%{"selected_media" => "single-id"})
    #=> {:ok, "single-id"}

    get_first_selected(%{})
    #=> :none

# `media_selector_url`

Generates a URL to the media selector page.

## Parameters

  - `return_to` - The URL to return to after selection (required)
  - `opts` - Keyword list of options:
    - `:mode` - Selection mode: `:single` or `:multiple` (default: `:single`)
    - `:filter` - File type filter: `:image`, `:video`, or `:all` (default: `:all`)
    - `:selected` - List of pre-selected file UUIDs (optional)

## Examples

    # Single image selection
    media_selector_url("/admin/blog/edit", mode: :single, filter: :image)
    #=> "/admin/media/selector?return_to=%2Fadmin%2Fblog%2Fedit&mode=single&filter=image"

    # Multiple selection with pre-selected files
    media_selector_url("/admin/gallery", mode: :multiple, selected: ["id1", "id2"])
    #=> "/admin/media/selector?return_to=%2Fadmin%2Fgallery&mode=multiple&selected=id1%2Cid2"

# `parse_selected_media`

Parses the selected media from LiveView params.

Returns `{:ok, [file_uuids]}` if media was selected, or `:none` if no selection.

## Examples

    parse_selected_media(%{"selected_media" => "id1,id2,id3"})
    #=> {:ok, ["id1", "id2", "id3"]}

    parse_selected_media(%{"selected_media" => "single-id"})
    #=> {:ok, ["single-id"]}

    parse_selected_media(%{})
    #=> :none
