G'day all,
I am slightly confused about how CGI parameters work. My
understanding was you could pass a parameter in the url :
&vesselid=2&endyear=2006
and then pick it up in the map file using:
[vesselid]
Which seems to work OK (I'm including it into a PostGIS query).
I also thought you could then put:
<select name="vesselid">
<option value="1" [vesselid_1_select]>Foam Bay</option>
<option value="2" [vesselid_2_select]>Mary Ann</option>
etc
or
<select name="endyear">
<option value="2006" [endyear_2006_select]>2006 </option>
<option value="2007" [endyear_2007_select]>2007</option>
</select>
into your html template, and expect it to print selected into the
appropriate box, but I get the following source returned.
<select name="vesselid">
<option value="1" [vesselid_1_select]>Foam Bay</option>
<option value="2" [vesselid_2_select]>Mary Ann</option>
</select>
<select name="endyear">
<option value="2006" [endyear_2006_select]>2006 </option>
<option value="2007" [endyear_2007_select]>2007</option>
</select>
This seems to be working with radio buttons and checkboxes and text
fields and text areas :
<td valign='top'>
<input type="radio" name="zoomdir" value="1" [zoomdir_1_check]>Zoom In
</td><td valign='top'>
<input type="radio" name="zoomdir" value="0" [zoomdir_0_check]>Pan
</td><td valign='top'>
<input type="radio" name="zoomdir" value="-1" [zoomdir_-1_check]>Zoom
Out
</td><td valign='top'>
<input type='text' name='zoomsize' value='[zoomsize]' size='3'>
all work fine. I note that Pericles online tutorial uses select
boxes, and they also work fine.
Is there a limit on how many form items may be used?
or what they may be called?
or how they are injected back into the template?
or have I completely gotten the wrong end of the stick on this one?
cheers
Ben
