[mapserver-users] Mapserver 6.0 regex

[Chris Green]

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?

Hmmm. 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.

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.
