Thanks so much!!! That's just what I was looking for. My features are now
displaying as I'd hoped. Is it difficult to extend this to change features
that are selected onhover? I added:
var selrules = [new OpenLayers.Rule({
symbolizer: {strokeColor:"blue",strokeWidth: 2},
elseFilter: true
})];
oStyleMap.styles["select"].addRules(selrules);
to your .js file but nothing happens when I hover over the points (it's a bit
gawdy but I just wanted to see if it would work). I think I need to add a
control but haven't tried this before. Will this work? The points aren't
currently changing. Are there additional considerations that I need to think
about. I'm just trying to port my old mapserver interface to openlayers and
any help is appreciated. Thanks again,
Todd

Subject: Re: [OpenLayers-Users] wfs stylemap example?
Hi Todd,
I have some to share. My WFS layer contains line features ( roads ) and
they have different color depending on their type ( Local road, Highway,
etc ). I hope this can be of any help :
============= otherfile.js =============
// prepare to style the data
var oStyleMap = new OpenLayers.StyleMap();
// Array of symbolizer and other values for ROL_CO_CLA attribute
// this will be used to create a html select list and will be used
// as the symbolizer array for the addUniqueValueRules function
// sorry, there's some french words here :)
var aRoadType = new Array();
aRoadType = {
AUT: {
text: "Autoroute",
strokeColor: "#ff0000", strokeWidth: 3 },
NAT: {
text: "Nationale",
strokeColor:"#ff8c00", strokeWidth: 2 },
REG: {
text: "Régionale - Reg",
strokeColor:"#ff8c00", strokeWidth: 2 },
COL: {
text: "Régionale - Col",
strokeColor:"#ff8c00", strokeWidth: 2 },
ACC: {
text: "Locale - Acc",
strokeColor:"#d2b48c", strokeWidth: 2 },
LOC: {
text: "Locale - Loc",
strokeColor:"#d2b48c", strokeWidth: 2 },
ACH: {
text: "Chemin forestier - Ach",
strokeColor:"#734c00", strokeWidth: 2 },
MRN: {
text:"Chemin forestier - Mrn",
strokeColor:"#734c00", strokeWidth: 2 }
}
// a style will applies to each drawned vector feature depending on
// the ROL_CO_CLA attribute value. It will match the good value and applies
// the corresponding symbolizers
oStyleMap.addUniqueValueRules("default", "ROL_CO_CLA", aRoadType);
// If no rules applies to the current vector feature, that means it's
// not a road, but an other type of feature like a circle for drag
// control. The "elseFilter: true" is used to display those vectors.
var rules = [new OpenLayers.Rule({
symbolizer: {strokeColor:"#FF0000",strokeWidth: 2},
elseFilter: true
})];
oStyleMap.styles["default"].addRules(rules);
============= yourHTMLFile.html =============
--- inside your <head> section ---
<script src="otherfile.js"></script>
--- inside your init() function ---
OpenLayers.Feature.Vector.style['default']['strokeWidth'] = '2';
// then some variables... map definition... base layer ... some WMS
layers ... and :
olWFSRoads = new OpenLayers.Layer.WFS(
"Roads - WFS", sMSURL,
{ typename: "roads", map: sMapPath },
{ extractAttributes: true, minScale: 49999,
typename: "roads", styleMap: oStyleMap
}
);
// then addlayers, controls, etc. and your <body>
