Method: CmsApplicationHelper#form_icons

Defined in:
app/helpers/cms_application_helper.rb

#form_icons(object_name, method_name, options = {}) ⇒ Object

Takes object_name and method_name as arguments (like other form helpers, such as text_field) and returns html containing form_error.gif and form_loading.gif. If there are no errors for the given field, form_error.gif is hidden using style=“display: none”. If there are errors, form_error.gif is shown, and its hover text lists the errors.
