mp-wp_genesis 2 SWFUpload Graceful Degradation Plug-in
mp-wp_genesis 3
mp-wp_genesis 4 This plugin allows SWFUpload to display only if it is loaded successfully. Otherwise a default form is left displayed.
mp-wp_genesis 5
mp-wp_genesis 6 Usage:
mp-wp_genesis 7
mp-wp_genesis 8 To use this plugin create two HTML containers. Each should have an ID defined. One container should hold the SWFUpload UI. The other should hold the degraded UI.
mp-wp_genesis 9
mp-wp_genesis 10 The SWFUpload container should have its CSS "display" property set to "none".
mp-wp_genesis 11
mp-wp_genesis 12 If SWFUpload loads successfully the SWFUpload container will be displayed ("display" set to "block") and the
mp-wp_genesis 13 degraded container will be hidden ("display" set to "none").
mp-wp_genesis 14
mp-wp_genesis 15 Use the settings "swfupload_element_id" and "degraded_element_id" to indicate your container IDs. The default values are "swfupload_container" and "degraded_container".
