I'm a newman in Mapserver. i want to use mapserver to distribute some
products in my office such as shape file, modis geotiff,and so on. i study
the tutorial create by Created by Pericles S. Nacionales . i think i grasp
the idea in section one ,that mean i learn how to write my own mapfile. but
i fail in section 2, when i try to imply mapfile into website. i don't
understand how to manage template file.
here is my mapfile
# The annotated map file (sort of)
# Created by Pericles S. Nacionales for the MapServer tutorial
# 20050408
#
# MapServer map file uses the pound sign (#) to denote the start of a line
# comment--each line that needs to be commented has to be prepended with a
"#".
#
# Map files begin with MAP keyword to signify the start of the map object.
# Well, the entire map file is THE map object. Enclosed between MAP and END
# at the very bottom of this map file, are keyword/value pairs and other
# objects.

# Layer objects are defined beneath the map object. You need at least one
# layer defined in your map file before you can display a map... You can
# define as many layers as you'd like although a limit is typically
hard-coded
# in map.h in the MapServer source. The default limit is set at 100.
You'd
# have to have a very specialized application to need more than 100 layers
in
# your application.

# CLASSITEM defines the non-spatial attribute that you will be using to
# separate a layer into classes. This attribute will be in the DBF file
# of your shapefile (it will be different for each data format). In
this
# example the shapefile states_ugl has an associated database
# (states_ugl.dbf) that contains an attribute called "CLASS". You will
be
# using two values in the CLASS attribute to separate the classes (also
# called themes) used in this layer--land and water. CLASSITEM is used
in
# association with the EXPRESSION parameter in the CLASS object. See
below.
CLASSITEM "湿润"
# Just like CLASSITEM, LABELITEM defines the database attribute that you
# will be using to draw labels. In this case, the values of the
attribute
# "STATE" will be used to label the states polygons.
LABELITEM "UNITENAME"
# The class object is defined within the layer object. You can define
as
# many classes as you need (well, there are limits as with layers, but
it's
# senseless to define more than ten on a "normal" layer. There are
# situations, however, where you might have to do it.)

it looks just like what i want..now i want to use this mapfile into a
template,just like turorial doing .
so i add some keword, in the map object before layer object.
TEMPLATEPATTERN 'tianjin_test.html'
WEB
TEMPLATE 'tianjin_test.html'
IMAGEPATH '/ms4w/tmp/ms_tmp/'
IMAGEURL '/ms_tmp/'
END # Every object in MapServer must have an END.;)
#

the template file is just like toturial

but problem happens when i click . it should be zoom in or zoom out but
