[Users] Example of a Search form reading from postgis

[Robert Buckley]

Hi,

I need to build a search form into a webap. My data is in Postgis and the form 
should be able to offer the following... 1. combobox listing firstly the layers 
in the map ( this would be search stpe 1), then 2. offer the columns from the 
the selected layer in step one, and then, 3. list the entries in the column 
selected in step 2.

I don´t want to offer an empty textbox for a search as there are many layers and 
many users won´t know exactly what they are looking for before the search 
begins. I find if one has the opportunity to narrow from step one the search 
becomes much more logical.


Has anyone seen such a thing? 

Thanks for any help,

Robert Buckley
