My task is to store the values in the database(postgreSQL) when the user inputs the lat-lon values in the form. and after submitting the form, the map should be displayed with markers at corresponding lat-lon values stored in DB. I have achieved this task using PHP,ajax & storing values in a text file. Now I have to do the same task using Geoserver+PostGis for which I am totally new. I have just installed Geoserver,postGIS,PostgreSQL in my system. I want your help to how to carry this task step by step. How to store these values in DB, how to retrieve them using geoserver.
Thanks in advance
