add geometry to feature layer

Question

I am looking for an example that will take a provided lat/long and attribute from a form and then create the point (or line) feature in a feature service layer

Any help would be appreciated.

The feature layer has an applyedits method that you can use to add new features to a feature layer. The following samples show how to use this method.

FeatureLayer inherits from GraphicsLayer, so you should be able to use the add() method. See http://help.arcgis.com/en/webapi/javascript/arcgis/help/jsapi/graphicslayer.htm#add.

To create a point graphic to add, where pointX and pointY are the x and y from your form:
// Create the Point
var point = new esri.geometry.Point(pointX, pointY, new esri.SpatialReference({ wkid: 4326 }));

// Create a point image symbol:
var symbol = new esri.symbol.PictureMarkerSymbol("/Images/point.png", widthInPixels, heightInPixels);

// Set up the template for the info window.
var infoTemplate = new esri.InfoTemplate("Point attributes", "${*}");

// Create a graphic from the point:
var graphic = new esri.Graphic(point, symbol, infoTemplate);

// Add the graphic
featureLayer.add(graphic);

Substitute your own spatial reference ID for 4326.
