<?php
dl('php_mapscript.dll');
$interval = $_GET['q']; // q is the value of what was selected
$options = array();
$map_path="C:\\ms4w\\Apache\\htdocs\\img_browser\\";
$map_file="img_browser.map";
$map = ms_newMapObj($map_path.$map_file);
$layer = ms_newLayerObj($map);
$layer->set("name", "Landsat");
$layer->set("data", "landsat_4");
print $layer->numitems;
This gives me the following.
[]
I (the user) "EXPECTED" that layer->set would actually set $layer to the
shapefile referenced in my Map file ... and that "numitems" would there
for give me the number of fields/items/attributes in that shapefile. Is
that not the case ?
++++++++++++++++++++++++++++++++++++++++++++++++++
My Map file (img_browser.map) has this layer entry ...
LAYER

DATA landsat_4
