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.
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
?>
I'm terribly illiterate when it comes to O-O stuff, so if you care to help,
the more explanation the better for me!!!
Thanks in advance.
