[mapserver-users] query creation issues

[Lime, Steve D (MNIT)]

Hi Mark: Personally I'd steer you to the simplified query templates as described here:

  http://mapserver.org/development/rfc/ms-rfc-36.html

This allows you to put everything in one place and better separates data from presentation. No more header/footer's. Plus you can have multiple presentations for the same layer. 

That said, the mapfile below doesn't have any queryable layers. There is no TEMPLATE defined for the one layer that is present.

If you want to use the new style templating you'd do something like this:

1- Define an output format:

  OUTPUTFORMAT
    NAME 'my-template'
    DRIVER 'TEMPLATE'
    MIMETYPE 'text/html; subtype=compass'
    FORMATOPTION "FILE=templates/my-template.html"
  END

2- Optionally make it the default query format (otherwise you need to use qformat CGI parameter):

  WEB
    QUERYFORMAT 'my-template'
    ...
  END

3- Make layers queryable by adding something like:

  TEMPLATE 'void'

4- Write your template, for example my-template.html might look like:

--- snip ---
<!-- MapServer Template -->
This is my template:<br/>

[resultset layer="mjrroads"]
  [feature]<b>Type</b>: [TYPE][/feature]
[/resultset]

Done presenting layers.
--- snip ---

Subject: [mapserver-users] query creation issues

Hello everyone,
 
I'm trying to create a query so I can query the roads/expressways from the map. I'm pretty sure I have created the headers and footers correctly but not sure...regardless i'm not entirely too sure where to stick the particular code in my .map file (shown below). I have bolded the code that I'm trying to incorporate into the .map file but not sure why it's not working. Thanks Mark
