On further investigation, it looks like the query statement is the cause
of trouble. There appears to be some change in syntax in MS 6.x.
I've been trying to re-write it, but to no avail. Can anyone provide an
example for a query statement for a shapefile data source, something
like this:
$value = "some value";
$query = '("[MYITEM]" = "' . $value . '")';
-In particular, what should be or should not be quoted?

Hi Alan,
I worked with the nextShape() a little bit as follows:
for ($i=0; $i<=($oLayer_master->getNumResults() - 1); $i++) {
while($oShape = $oLayer_master->nextShape()){
$oResult = $oLayer_master->getResult($i);
$oLayer_master->open();
$oShape = $oLayer_master->getShape($oResult);
$oShape->draw($oMap,$oLayer_shape,$oImage);
$oLayer_master->close();
}
}
That appears to have fixed the error message I was getting, but it still
does not draw results (it should).
You brought up a good point regarding the query. Here is the query
language, at least what I could find (it's worth noting I did not write
the application, but am now responsible to maintain it):
$query = $_GET['qpub'];
$query = '("[PUBCODE]" = "'.$_GET['qpub'].'")';
$oLayer_master->queryByAttributes("PUBCODE", $query,
MS_MULTIPLE);
pubExtent2($oLayer_master, $oMap);

Hi Bob,
I do not see any query in your code. Not sure why numresults return a
non-zero value. Check the example of the getShape() or nextShape()
functions in the documentation:
