Hi Steve
That's a very constructive suggestion. With no mapscript involved and with the mapfile set up without a cluster class I added into the layer section: FILTERITEM 'Groups' FILTER /group4/ This worked: I got only group4 features. Then I changed the mapfile to use a cluster class, with no filter: this worked, I got all features clustered and with labels showing the FeatureCount for each cluster. Then I inserted the same FILTERITEM and FILTER into the layer as above, and there is no output. Nada. So it seems to be not a mapscript problem, but some kind of conflict between clustering and filtering in Mapserver?

A plain 'ol regex expression did not change between 5.6 and 6.0, so this is still valid: FILTERITEM 'myitem' FILTER /myregex/ Where regex's changed is inside logical expressions: FILTER ('[myitem]' ~= /myregex/) becomes FILTER ('[myitem]' ~ 'myregex') There are regression tests for these cases (query/filters.map) so I'm pretty sure MapServer proper is working ok. You might try setting the filter and filteritem directly in the mapfile see if that works. If it does then it's likely a problem with PHP/MapScript. Steve From: [email protected] [mailto:[email protected]] On Behalf Of Chris Green Sent: Monday, June 20, 2011 12:39 PM To: [email protected] Subject: [mapserver-users] Mapserver 6.0 regex I have one (hopefully the last!) problem with migrating from Mapserver 4.6 to 6.0, this time over the use of regex. Using Mapscript on a Fedora platform I have been setting a filter in this manner: $map=newMapobj("/var/www/vhosts/mysite/httpdocs/test.map"); $layer1=$map->getLayerByName("test1"); $layer1->set("filteritem", "Attribute1"); $layer1->setFilter("/target/"); This worked fine, but not anymore. I see in the migration guide that a regex should now be delineated as a string so I assume that "/target/" should become "target". But that doesn't work either. I am wondering if part of the problem is that as well as going from Mapserver 4.6 to 5.0 I also changed from Fedora to Ubuntu 10.04, and I see from the Mapserver documentation on Expressions that the OS may affect regex operation. Am I missing something obvious here? I am really tired of going in circles over this. Chris
