[postgis-users] simple puffer script

[Robert Buckley]

Hi,

I have to use postgis to create a puffer layer. I could do this within postgis, 
but the problem is that I have to display the result in my webapp!

I have seen many examples on how to puffer, but none where a user inputs a value 
from a textbox e.g 50 and presses a button to calculate a puffer over the data 
with a 50m puffer and then displays the resulting vector layer in the openlayers 
map.


Is this very complex?
How should I start coding this?  PHP to script the postgis query? 

thanks for any scripts, tips or advice.

yours,

Rob
