<p class="MsoNormal">Hi all,<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I am using mapserver to allow WFS in Openlayers to access point data held in a PostgreSQL / PostGIS database. The mapfile includes the following statement:<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">...<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><i>INCLUDE "readonly.config"<br>
DATA "geom FROM table USING srid=32636 USING UNIQUE fid"</i><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">...<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Currently I make a new mapfile for each site visit to each project. However this means every time a new site visit or project is made, I have to create a new mapfile, and the only thing that changes is the "table" part of the statement.
All the styling info is in the Openlayers WFS statements.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Is it possible to get Openlayers to pass variables to the DATA parameter (e.g. a different table name) when called so that I can reuse the same mapfile for different WFS calls? <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Or alternatively, could store the point data in the same PostgreSQL table and have some other way of filtering the data (e.g. on timestamp)<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Am I misunderstanding how I should be using mapfiles? <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>

<div>
<p class="MsoNormal">thanks,<o:p></o:p></p>
