[mapserver-users] Dinamically changing HTML Template using CGIparameter? (instead of hardcoded)

[Wim Blanken]

Hello Kresh,

 

In Mapserver version 5 you can change the HTML template as follows.

 

At first you will have to set the templatepattern in the root part of the
mapfile (below MAP).

 

      TEMPLATEPATTERN   ".*"

 

Then you can change the template in the cgi with:

 

...&map_layer[Wegen]=TEMPLATE+othertemplate.html

 

'Wegen' is the name of the layer.

 

You may have to put the name of the template between single quotes...

It is also propably needed that you specify the full path to the template
file.

 

Regards,

Onderwerp: [mapserver-users] Dinamically changing HTML Template using
CGIparameter? (instead of hardcoded)

 


I have one mapfile, let say, PACITAN.MAP, with two template files:
PACITAN-TMPL.HTML and PACITAN-PRINT-TMPL.HTML. The former is the "primary"
template for the normal web map display, while the latter has "cleaner look"
for printing purpose (print page).

The print page (PACITAN-PRINT-TMPL.HTML) is called from the "primary"
template page using JavaScript window.open() function. 

When calling the print page, I can easily pass (and manipulate, if
necessary) map-related information using CGI parameters. For example, layer
information (ie which layers are selected) is passed with layers=[layers]
CGI parameter, while extent information is passed with mapext=[minx],
[miny], [maxx], [maxy] parameter.

The problem is: since the name of HTML template is hard-coded in the *.map
file, I have to create another map file named PACITAN-PRINT.MAP, which is
basically an exact copy of PACITAN.MAP, but using PACITAN-PRINT-TMPL.HTML as
template  (hard-coded in the mapfile, of course).

If I can dynamically change the name of the HTML template using CGI
parameters, I don't have to use two versions of mapfile; I can just use one
mapfile with two HTML templates and be done with it.

The problem is; is it possible to pass the name of the HTML template using
CGI parameters? And if it is, then how? I have browsed MapServer
documentations and this is all I found:

TEMPLATE has been removed, since the map_web_template syntax can be used to
alter a template file. Simplifies security maintenance by only having to
deal with this option in a single place. Note that the TEMPLATEPATTERN of
the mapfile has to be used to enable this feature.

However, save the vague reference above, I just could not find any other
explanation about the map_web_template syntax above. Is it a CGI parameter?
Can I just use the map_web_template parameter in my url, to specify which
template to use?

Many thanks,
-Kresh
