If you aren't able to use Armin's solution, You can try this solution if you
can use a particular feature in the map and you are using postgis and
postgres tables:
<?php
if($_POST['Submit'])
{
$qry = 'SELECT xmin(box3d(the_geom)), ymin(box3d(the_geom)),
xmax(box3d(the_geom)), ymax(box3d(the_geom)) from subdiv where SUBDIVNAME
like \'' . strtoupper($_POST['subdiv']).'%\'';
$dbconn = pg_connect("host=localhost dbname=mydb user=myuser
password=mypassword")
or die('Could not connect: ' . pg_last_error());
$result = pg_query($qry) or die('Query failed: ' . pg_last_error());
$line = pg_fetch_array($result, null);
print $line['xmin'] . '+' . $line['ymin'] . '+' . $line['xmax'] . '+' .
$line['ymax'];
}
else
{
print <<<END
<form method='post' action='subgeom.php'>
Subdivion Name: <input type='text' name='subdiv'><br>
<input type='submit' name='Submit' value='Submit'>
</from>
END;
}
?>
I used this code to select the geometry of housing subdivisions so that some
of my fellows could create links back to mapserver and I wouldn't have to do
it for them. You could use the geometry in your image map links or in
javascript to pass to map.phtml, or as I've done as links in a select tag:
<select name='mysubdiv'
onchange="window.location.href=this.options[this.selectedIndex].value">
<option> Subdivisions </option>
<option
value='http://myserver.com/cgi-bin/mapserv?imgext=2460756.25+732970.6875+2465750.75+737314.8125&map=%2Fmaps%2Fexample%2Fdemo1.map&program=%2Fcgi-bin%2Fmapserv&img.x=250.0&img.y=200.0&zoomdir=1&zoomsize=2'>Two
Rivers</option>
<option
value='http://myserver.com/cgi-bin/mapserv?imgext=2461069.5+695974.25+2462774.75+697804.0625&map=%2Fmaps%2Fexample%2Fdemo1.map&program=%2Fcgi-bin%2Fmapserv&img.x=250.0&img.y=200.0&zoomdir=1&zoomsize=2'>Soda
Springs</option>
</select>
The php code above could very easily take a very long list and be run in a
loop outputting links that you want to use.
Remember too that all you really need to do to get retangles is to calculate
how far apart the center of each of your tiles will be then run a loop that
generates point coordinates for each point within your map's extents and
then just do:
$map->zoompoint(-10, $mypoint, $map->width, $map->height, $ext);
In php or use javascript to call mapserver.js zoompoint (using the same
trick with your image coordinates) or call map.phtml directly with the
correct query string.
The nice thing about this solution is that you aren't tied to pmapper's
display. You get all of the advantages of pmapper, but you can also have a
nice clean interface to mapserver for something like a public website and
still use many of pmapper's features.
Just a suggestion.
