[OpenLayers-Users] simple gazetteer test with geojson

[Gery .]

Thanks for the answer but still I don't get how to do that. It seems to me that the PHP script generates SQL WHERE filters (@params) but I think I have to set that up before the search button is triggered in OL, and what I need is to search for the feature from a search button in OL. I read the filtertoParams but don't get it, do you have some code or example available for this? also, why is this procedure different from XML and GeoJson?




For name__like to be taken into account (1) your postgis_geojson.php script needs to support comparison filters in the requests, and (2) Protocol.HTTP object needs to have a filterToParams format. By default, if no filterToParams format is passed to the constructor, an Protocol.HTTP instance is configured with QueryStringFilter format, which, for example, converts a LIKE filter on attribute "name" into name__like=%value% in the query string.

Hope it helps
