[mapserver-users] PHP-Mapscript - clusterObj ?

[Chris Green]

Hi Tamas

 

Thanks for your comment. My first thought was that it should be available from layerObj, and I spent quite a while trying variations like:

$map = ms_newMapobj("/var/www/vhosts/mysite/httpdocs/test.map");

$layer1=$map->getLayerByName("test1");

$cluster1=$layer1->getClusterByName(“cluster1”);

But unfortunately I couldn’t make anything like that work. Anyone know how this clusterObj works in php-Mapscript?

Chris,

clusterObj should not be constructed from scratch, it is an existing member of layerObj. Not sure how is that working in PHP, however.


Best regards,

Hi list

 

I am running Mapserver 6.0 under Ubuntu 10.04 with PHP-Mapscript and I have been trying to get clustering to work with Mapscript. Actually it works fine when using a mapfile very similar to the ‘Clustering Railway Stations’ example given in the 6.0 documentation if I use the mapfile to generate a WMS layer without Mapscript. However using the same mapfile I can’t get the clustered output to appear with Mapscript when I try the usual construction along the lines of:

 

$map = ms_newMapobj("/var/www/vhosts/mysite/httpdocs/test.map");

$layer1=$map->getLayerByName("test1");

..

..

..

$image=$map->draw();

$image_url=$image->saveWebImage();

 

This structure works on a non-clustered layer in the same mapfile. I can see in the documentation for MS RFC 69 that the idea is to use a new Mapscript object called clusterObj, but I can’t find any information on how to construct a clusterObj and several hours of trial and error yesterday didn’t get me very far. Can someone tell me how I should set up and use clusterObj?
