Hi everybody,
First let me tell you that I hardly speak
english and that this is the first time I join a list,
so if a make a mistake and upset somebody, please let
me know and I'll try to rectify my behaviour. Thanks.
My questions (I'm using PHP MapScript):
How can query a group of shape files and get the
contents of their corresponding .dbf's to, then, query
a datasource (Database, dbf, etc).
I've tried this code:
$map = ms_newMapObj($map_file, $map_path);
...
for($i=0; $i<$map->numlayers; ++$i) {
$layer=$map->getLayer($i);
printf("% 2d %s",($i+1),$layer->name.':
type['.layer_type($layer).'],
status['.layer_status($layer)."]");
if($my_extent && $layer->isVisible()) {
if(@$layer->queryByRect($my_extent)==MS_SUCCESS) {
$nres=$layer->getNumResults();
if($nres) {
$layer->open();
for($x=0; $x<$nres; ++$x) {
//$layer->getShape($r->shapeindex,
$r->tileindex); // got errors with this one
$shape=$layer->getShape($x, 0);
var_dump($shape);
}
$layer->close();
}
}
}
}
This is part of a app that zoom, pans and switches
layers on/off (the things I've did so far).
I have two problems:
1) I seem to get only the first record of the .dbf
2) I'm using a precompiled version of Linux HostGis
2.4.31 with MapServer 4.6.0 and the documentation in
http://mapserver.gis.umn.edu/docs/reference/phpmapscript-class
the layerObj has much more methods and properties than
what I got in my installation.
Thanks in advance for any help.
