IMHO, layerswitcher is too primitive for this. I use a combo box (eg http://kite.gns.cri.nz/PBE/#MAP:OPAConfig.json) to select the searchable layer and then user can try point, polygon or text searching. Its unlikely that all of your layers are seachable. > Step 2: After knowing the selected layer , Using php search that > corresponding table for the search string in names column , if it is present > get the latitude and longitude values.

Depending on your database, you can just use WFS to make the query. In the response function from the WFS query, the "features" object will have the geometry to work on.
