RE: [mapserver-users] shape->draw problem
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:

I do believe I’m retrieving a valid shape. What’s even more confusing,
I’ve had to replace the getFeature with getShape in other parts of the
application and it seems to work.

[mapserver-users] shape->draw problem
I'm upgrading an application from Mapserver 5.6 to 6.0.1, PHP MapScript.
I'm having a problem with one section of code where it gives a
shape->draw command. In MS 5.6, the Shape was derived from a getFeature
method, but in MS 6 this had to be changed to a getShape. The next
command is to draw the shape. This returns the following error:
Fatal error: Uncaught exception 'MapScriptException' in
C:\ms4w_303\apps\mgs\htdocs\drawMap_detail_spatial.php:101 Stack trace:

{main} thrown in C:\ms4w_303\apps\mgs\htdocs\drawMap_detail_spatial.php
on line 101
Here is the code leading up to the error:
$oLayer_shape = $oMap->getLayerByName("master");
for ($i=0; $i<=($oLayer_master->getNumResults() - 1); $i++)
{
$oResult = $oLayer_master->getResult($i);
$oLayer_master->open();
// $oShape =
$oLayer_master->getFeature($oResult->shapeindex,-1);
-Old getFeature method-commented out and replaced on next line:
$oShape = $oLayer_master->getShape($oResult);
$oShape->draw($oMap,$oLayer_shape,$oImage);
-fails on this line
$oLayer_master->close();
}
I do believe I'm retrieving a valid shape. What's even more confusing,
I've had to replace the getFeature with getShape in other parts of the
application and it seems to work.
