Feather: Image field

Feather's sfImageField directive enables you to select and display an image from the existing libraries in your website. In addition, you can also use this directive to upload an image to a library.

After you select an image, the default template lists information about its base properties such as type, size and upload date. To change the selected image, using the image selector and you can also edit the image's properties. For more information, see Feather: Use an image selector.

You can use the directive in the frontend, as well as in the backend, for example, on a page, as well as in a widget designer. For more information, see Feather: Use content selectors outside of widget designer views.

The sfImageField is a directive with an isolated scope that is defined in a module with the same name: sfImageField. For more information, see AngularJs Isolated scope.

The following image is an example of an image field:

The sfImageField directive exposes the following attributes:

The following example demonstrates how to add a image field directive in a widget designer's view.

To enable AngularJs to link the sfImageField directive in your custom designer view, you must load the script of the directive and add a dependency to the module:

1. Feather automatically registers the scripts you need and, if no other designer view with explicitly set priority exists, Feather sets your designer view priority 1. In case you need to have full control over the scripts that are loaded or you want to set custom priority, you can alternatively create your own DesignerView.YourView.json file. If you have a JSON file that matches the convention (even if empty), this automatic scripts registration will not occur. In your DesignerView.YourView.json file, add a scripts array. As a result, the file content should be similar to the following:
2. Feather automatically finds all AngularJS modules you rely on and references the widget designer to them. In case you rely on custom AngularJS modules or have logic that needs an AngularJS controller, you can create your own designerview-<yourview>.js file. If you have a .js file that matches the convention (even if empty), this automatic modules referencing will not occur. In your designerview-yourview.js file, right before the definition of your custom view controller, place the following code snippet:

   Since there is no selected image when the controller is initialize for the first time, the sf-auto-open-selector attribute in the code above opens an image selector. After you select an image, the image and its ID are stored in their respective scope variables: selectedImage and selectedImageId. The imageProvider variable holds the name of the provider from which image libraries are loaded.

   NOTE: The image selector can load images from different providers.

3. In your DesignerView.YourView.cshtml file, place the following tag where you want to render the sfImageField directive:
