Andrea,
What I do is set the default_idvalue to 1=1 and change the filter to
FILTER %idvalue%. Then the cgi value is something like idvalue=id=1
Your valididation regex becomes more complex though.

Hi,
I need to set a layer to allow to retrieve in the response all the
elements available in the layer, and when the request has a specific
parameter it should apply a filter to limit the show to only the
filtered geometries.
To do this until now I have set this configuration:
LAYER
...
DATA geometry from table using unique gid srid=25832
FILTER PK_FIELD like '%idvalue%'
VALIDATION
'idvalue' '^[a-zA-Z0-9\-_]+$'
END
...
METADATA
'default_idvalue' '%'
This configuration work pretty well when the PK is a string field.
Infact is the request has no the idvalue parameter it show all the
records , thx to the default_idvalue % definitioni,
instead if the request has a parameter as example
..idvalue=xxx1
It show only the specific item having PK_FIELD=xxx1
Now I have the same need for a layer where the PK is numeric.
With this layer the solution described seem don't work, infact the
'default_idvalue' '%'
is not working with a numeric field.
There same other solution to have the same result?
I need to show all the records and apply the filter only when there is
a specific parameter in the request.
Thx,
