[mapserver-users] MapServer Layer Filter not applying to WFS

[Hawk AA]

Hi,

 

Thanks for the help.

 

Using filter in the CLASS did nothing more than adding FILTER to the layer
tag. I tried this definition:

 

LAYER

                               NAME Traseer

                               GROUP TelMe

                               TYPE LINE

                               DATA "TM_Nett/TM_Traces"

                               minscaledenom 0

                               maxscaledenom 5500000

                               CLASS

                                               EXPRESSION ('[type]' !=
"LUFT")

                                               TEMPLATE 'void'

                                               NAME "TelMe_Traseer"

                                               STYLE

                                                               COLOR 255 0 0

                                                               WIDTH 2

                                               END

                END # Layer

 

It does not display the data, nor queryable in MapScript, but I can get the
feature geometry with WFS.

 

I’ve until now used CONNECTIONTYPE OGR with CONNECTION, and it has worked
flawlessly. Recently, when upgrading to PHP 5.4, it started UTF-8 encoding
my tables. I’ve addressed the issue here:
http://comments.gmane.org/gmane.comp.gis.mapserver.user/49756 . I have some
more research to do regarding the issue, but I’d be very thankful for any
hints.

One other idea. I believe you can avoid using OGR by adding your filter to
class expressions and setting a template (which enables queries) at the
class level. Class expressions are always checked. If you have one class
it’s easy:

 

LAYER

     NAME Traseer

     GROUP TelMe

     TYPE LINE

     DATA "TM_Nett/TM_Traces"

     CLASS

        EXPRESSION'[type]' != "Bru")

        # Styling and more etc....

        TEMPLATE ’void’

      END

      # No template set at the layer level

END

 

Might consider WMS-only vs. WFS-only layer defs to simplify life if you have
multiple classes.

Hi there, mailing list,

 

We have a customer sending us data with sensitive information. The most
convenient way for us is to receive the complete data set and applying a
filter in the mapfile.

 

The layer definition looks like this:

LAYER

                               NAME Traseer

                               GROUP TelMe

                               TYPE LINE

                               DATA "TM_Nett/TM_Traces"

                               FILTER('[type]' != "Bru")

                               #Styling and more etc....

END

 

This works flawlessly using PHP Mapscript and the mapserver WMS service. The
data is not accessible. The problem occurs when querying by WFS. The
Mapserver WFS service seems to omit the FILTER information and opens up for
selecting items with the type “Bru”, which is a serious security flaw. 

 

I’d consider this as a bug, although I’m not certain. If anyone please can
confirm this, or show me how to make mapserver filter data in WFS as well,
I’d be much obliged.

 

Best Regards,

Håkon
