Dear anyone willing to help,
I'm having a hard time interpreting how to properly execute runtime cgi
variable substitution using an of type=text.
If I replace '%county%' with a sample county attribute value in single quotes
the EXPRESSION works and is displayed on the returned html template.
Currently my html input variable in the template looks like this :
...and my mapfile variable to be substituted for looks like this:
LAYER
NAME blah_ohio
STATUS OFF
TYPE POINT
DATA BLAH/BLAH_Ohio
PROJECTION
"init=epsg:3754"
END
CLASS
NAME 'Class1'
EXPRESSION ('[County]' eq
'%county%')
STYLE
SYMBOL "circle"
COLOR 250 50 50
OUTLINECOLOR 0
0 0
SIZE 2
END
END
METADATA
"wms_title" "blah_ohio"
"wms_srs" "epsg:4326"
END
END

I couldn't find a way to do it through modifying the URL that's passed either.

[mapserver-users] Run Time Substitution and Mapscript questions
I am attempting to use python mapscript to generate some maps, however I am
running up against some problems.
My mapfile layer has a CONNECTION of
""http://127.0.0.1/cgi-bin/wms/rs/seacoos_rs_test?TIME_OFFSET_HOURS=%time_offset_hours%";
My mapscript test script has an OWSRequest that has a
setParameter("TIME_OFFSET_HOURS", "2")
When checking the web logs, I see the request come in, however the
substitution is not being made, I see
"/cgi-bin/wms/rs/seacoos_rs_test?TIME_OFFSET_HOURS=%time_offset_hours%"
Are these types of substitutions still possible?
Thanks,
Dan

Re: [mapserver-users] Run-time substitution
Alright, thank you for confirming run-time substitution's lack of LAYER NAME support. My setup involves MapServer 5.0, OpenLayers 2.7, and TileCache 2.1. Maps are WMS and not all layers (including the ~50 in my first post) are cached. I've written a small javascript library that handles feature queries, loads custom tools, and does the communication between client interaction and MS/OL/TC. Most maps are in html pages for partner and sponsor projects. Mapscript intrigues me and I should understand it better, but I'm still not clear on the topic in general (even after going through the documentation). It sounds like instead of OL doing direct MS requests it would hit a (Python, etc) CGI that handled MS requests and generated the relevant images? An OL mailing list search for mapscript just returned a bunch of results, I'll research some more. Thank you. ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
Re: [mapserver-users] Run-time substitution
It's not (and won't be) supported. There may be other ways to structure things but you'd need to tell the list a bit more about your setup.

Re: [mapserver-users] Run-time substitution
I want to confirm that LAYER NAME is not supported in run-time substitution before I re-work everything. It sure isn't, confirmed. A recompile, though, should be able to enable it. If you have elementary C skills and are used to compiling MapServer from source, that may present little difficulty. -- HostGIS, Open Source solutions for the global GIS community Greg Allensworth - SysAdmin, Programmer, GIS Person, Security Network+ Server+ A+ Security+ ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
[mapserver-users] Run-time substitution
Hello, I have ~50 layers/shapefiles that are the same datasets scaled to various values, used in OpenLayers. My map file for this data is quickly growing (3000+ lines) and I was hoping to use run-time substitution to reduce this, changing the LAYER NAME and DATA. I've read the documentation on run-time substitution which didn't mention LAYER NAME as being supported (other posts made it sound like it specifically was not supported), and which I would need to change for OpenLayers. I want to confirm that LAYER NAME is not supported in run-time substitution before I re-work everything. Thank you.

Re: [mapserver-users] Run-time Substitution vs. Variable Substitutionand what are the Parameters Supported?
Variable substitution refers to those parameters that can have part of their value changed remotely. The supported parameters are: LAYER: data, tileindex, connection and filter CLASS: expression Setting up parameter validation is STRONGLY encouraged. In your layer metadata you'd define keys based on variable names to do validation. For example, if your variable was called 'foo' and you wanted to allow a single digit integer from 1 to 9 as a value you'd do: METADATA ... 'foo_validation_pattern' '^[1-9]$' ... END The value of 'foo' would have to pass the supplied regex before the parameter would be altered. It is up to you to author the correct validation pattern. MapServer also supports some URL-based configuration. This is different than substitution in that you are completely changing values of object parameters or even creating new objects. That is, you can change a class color or create a new point feature. Support here (at the moment) is limited to parameters that are validated as part of mapfile parsing. For example, MapServer checks to make sure a color is of the correct format, that a double is a double and so on. The only two exceptions are layer DATA and TEMPLATE properties and they are required to validate against DATAPATTERN or TEMPLATEPATTERN before being used. This is all going to be generalized and improved in 5.4.

[mapserver-users] Run-time Substitution vs. Variable Substitution and what are the Parameters Supported?
Hi, What is the difference between Run-time Substitution vs. Variable Substitution within a map file? They look like they are the same thing. Also what are the Parameters Supported? >From documentation that is almost 3 years old it lists the following parametes (listed below) is this list complete? - LAYER: DATA (must validate against DATAPATTERN) - LAYER: TILEINDEX - LAYER: CONNECTION - LAYER: FILTER - CLASS EXPRESSION Thanks, -- John J.
