[mapserver-users] Need help: How to make drawn layer visible?

[Jan Mantkowski]

Dear all,

i have rebuild the php script and the mapfile and sortet out a lot of
errors.
But i am still unshure how to make the dynamically drawn layer to appear?

Please have a look at my phpscript and the according mapfile.

Thank you all,

Jan



At the screen right now i get this:

Map name=FIRSTMAP, num lay=2
Layer num=0, name=world
Layer num=1, name=users

2500000    -4000000   Jan
8000000    1000000    Jose
4000000    3000000    Madeleine
2000000    4000000    Fritz

And a map showing europe.

php script:

<?php
dl("php_mapscript_35.dll");

$map = ms_newMapObj("europe.map");
$layerName="users";

printf("Map name=%s, num lay=%d<br>\n", $map->name, $map->numlayers);
for ($i=0; $i<$map->numlayers; $i++) {
  $myLayer = $map->getLayer($i);
  printf("Layer num=%d, name=%s <br>\n", $i, $myLayer->name);
}
echo"<br>";

//mysql_q
$db = mysql_connect("localhost", "root", "");
mysql_select_db("Rogue",$db);
$results = mysql_query("SELECT * FROM nuke_map",$db);
if ($results === false) die("failed");
//display result of mysql query on screen
while ($show = mysql_fetch_array($results, MYSQL_ASSOC)) {
echo
$show["pn_lon"]."&nbsp;&nbsp;&nbsp;&nbsp;".$show["pn_lat"]."&nbsp;&nbsp;&nbs
p;&nbsp;".$show["pn_name"]."<br>\n";
}

//drawPoints
$layer =  $map->getLayerByName( $layerName );

   // Loop through result of point query and:
   while ($line = mysql_fetch_array($results, MYSQL_ASSOC)) {
                 $pt = ms_newPointObj();
                 $pt->setXY( $line["pn_lon"], $line["pn_lat"] );
                 $pt->draw($map, $layer, $image, 0, "TEST");
                 $layer->set('status', MS_ON);
                 $layer->draw($image);
          }
// ende
$img = $map->draw();
$url = $img->saveWebImage(MS_PNG, 0, 0, 0);
printf("<IMG border=1 SRC=%s WIDTH=%d HEIGHT=%d>\n", $url, $map->width,
$map->height);
?>
