I've been able to generate a map using the OGR CONNECTIONTYPE to pull data
from a MySQL table.
Each record contains the geometry and extents and I've figured out how to
set the extents before drawing the map. However, if I could dynamically
modify the DATA element of a layer's CONNECTION, the end result would be
much better.
When I dump the $map array, I don't see an element that corresponds to the
CONNECTIONTYPE or the DATA string for the OGR connection.
The CONNECTIONTYPE, CONNECTION and DATA elements are members of the
layerobject, not the map object. Try something like this::
$layer = $map->getLayerByName('yourlayername');
$layer->set('connectiontype', MS_OGR);
$layer->set('connection', 'new value');
$layer->set('data', 'new value');
I'd be grateful if someone could post the equivalent to what I use to change
the EXTENT for the current map. I use something like this:
<?php
$row=mysql_fetch_assoc($result);
$map->setExtent($row['x1'],$row['y1'],$row['x2'],$row['y2']);
$image->$map->draw();
// then show the result
?>
Using $map->setExtent() is the right way to go.
Maybe I misunderstood the question or what you're trying to achieve?
