[mapserver-users] Show only one POI on the map

[valerio vianello]

Hi Tamas,

thanks for the replay, 

I can set the FILTER into the map file but How can I change the FILTER value from the template ?

I need to change the point to show dynamically based on user selection.

At the moment the only solution that I have found is to put each Poi in a different layer using a filter in each layer to choose the Poi. So from the template to change the Poi  the user have to change the layer.   

But I hope to find a better solution.

best regards,
Valerio

Valerio,

How about setting a FILTER based on the attributes of the layer so as
to select the single point to be rendered?

Best regards,

Tamas
