Hello,
I am working on a filter plugin. So far, most of the client side is
done. There is an ini file, that contains a list of layers and templates
of the filter strings. The client class parses the form and generates an
array of FilterRequest objects (FilterRequest implements CwSerializable)
which looks like
Array
(
[0] => FilterRequest Object
(
[layerId] => wzbra_branche
[filter] => the_geom from (SELECT gid, the_geom ...) USING
UNIQUE gid USING SRID=31468
[className] => FilterRequest
)
[1] => FilterRequest Object
(
[layerId] => kreise
[filter] => the_geom from (SELECT gid, the_geom FROM ...)
USING UNIQUE gid USING SRID=31468
[className] => FilterRequest
)
)
Further, I created a Server class that implements
ClientResponderAdapter. Both parts of the plugin are loaded in the ini
files. I also have an idea about setting the filter on the server side.
However, I am stuck with the communication between client and server:
1. How do I transfer an array of FilterRequest objects? Do I need a
separate class in the common part?
2. How should the wsdl for the FilterRequest class look like? Probably
<complexType name="FilterRequest">
<all>
<element name="layerId" type="xsd:string"/>
<element name="filter" type="xsd:string"/>
</all>
</complexType>
But how do I handle the array of requests?
3. Which function on the server side should I use to handle the request
and set the filter strings?
And finally a general question:
I would like to prevent that Cartoweb fails and shows an error message
if the provided filter is wrong, e.g. syntax errors. Supposed a user
provides an incorrect filter string, can I somehow test the filter and
ignore it?
Thanks,
Dirk
