Hi Peli,

Please CC to the list, because otherwise I might end up giving the same
explanation to 10 different people individually.
As I mentioned, you probably have to join your data. Meaning create one
single layer that has the information that you are after. Either that,
or you have to partially rewrite the widget. To get the functionality
you want would need some pretty elaborate customisation, so you should
probably just do joins on your data.

regards,

Jacob

	Hi Jacob:
	I still have a trouble with my assignment.And sorry about my
early explanation.
	Now , i will ask you in another way.What i' am understand here
is, if i want to make a link between two table (table in same database
and also , table in different database), i need to use and adjust the
LocateByAttribute widget.So, if you have any suggestion, please tell me
what are the proper widget i need to use.

	As an example, i use the chameleon example that include in the
'ms4w PHP5 Base Installer version 2.2.3'.The example that i used is
sample_enhanced_jsapi.phtml
(chameleon/samples/sample_enhanced_jsapi.phtml).In this example, i
already success to used the search function (in the HOW_TO_USE.txt) from
LocateByAttribute widget.And i use the search function(button) at the
sample_enhanced_jsapi interface to find the 'rail' record, i choose to
search the
	'gid' rail data.So, all the rail data that have the same 'gid'
data value that i insert in the search function will shown up in popup
interface , because i use the popup implementation.After that, i close
the rail record that shown up early and start the new searching.

	Now i search the 'road' record, i also search the 'gid' data in
the road record.So, all the road  data that have the same 'gid' data
value that i insert in the search function will shown up in popup
interface and will arranged it by the gid value.The gid value that shown
up is the number 1,2,3,4,5,...11... and so on.So, i want to get the
record from the rail table to display in another popup, that have the
same gid with the road 'gid' data by clicking the road 'gid' data that
shown up early in popup.For explanation, if i click the road 'gid' data
(number 1) so, all the record or data from the rail record that have the
same 'gid' data(number 1) will shown up in another popup.So, what can i
do, please help me
	to solve this problem.Thank you.

		Hi Peli,

		The LocateByAttribute widget allows you to specify which
attributes you want shown in the initial results page, using the
"spatialsearchlist" metadata attribute. It's in the how_to_use.txt file
that comes with it.
		If you want to join your data to other data, it's best
to do this in advance, using a database or a GIS (assuming your
relationship is one-to-one) rather than on the fly, because it is faster
and more straightforward. If your join is one to many, it would not be
easy. It would not be straightforward to adjust the LocateByAttribute
widget to do this.
		To be honest, I don't understand your explanation of
what links to what, because you are mixing cities and states. Please let
me know if you still have trouble.

		regards,

		Jacob

			Hi there,i'am now try to learn the chameleon
example for GIS web development
			and try to use the LocateByAttribute file.Now i

is,California,New York,Washington

have the same name to link, 
			As an example , table 1 have the california name
,and table two also have 
			the California name ,so the data that call above
