I'm just a MapServer user.  I've copied this reply to the list so your

To me would be very good that mapserver documentation includes a since
version.subversion.release flag at documentation function names like php
does on their site.

And for those changes and breaks on code the user contribution on end of
function descriptions would be welcome too.

Example from php

pg_connect
(PHP 4, PHP 5)
resource pg_connect ( string $connection_string )

http://br2.php.net/manual/en/function.pg-connect.php

I don't think that the documentation has caught up with the changes in the
program.  People using older versions of MapServer have to use the older
method and the new method is used for 5.6+ version.  It was described
briefly in the migration document but took me some experimentation to get
results.

Hi,
thank you very much, shapeObj resultsGetShape is the solution.
resultsGetShape works fine.
But I don't understand why shapeObj getFeature is in the documentation?

This problem is due to the new single pass query in 5.6.

I have marked your code with what I am using.

Try these mods marked with "*************************":


@$datQuery = $query_layer->queryByRect($qRect);

 //number of objects
 $resnum = $query_layer->getNumResults();  echo "number of objects:
".$resnum."<br>";

 //if query success
if ($datQuery == MS_SUCCESS) {
//  $query_layer->open();      // <<REMOVE OPEN AND CLOSE ***********

 //first row
 $result = $query_layer->getResult(0);


 //$shpobj =
$query_layer->getShape($result->tileindex,$result->shapeindex);
 // resultsGetShape is now the way to get the shape object
***************************
 // note: change of order in arguments
************************************************
 $shpobj = $query_layer->resultsGetShape($result->shapeindex,
$result->tileindex);


 //read attribute
 $attr = $shpobj->values;

 //write headline
 echo '<table cellspacing="0" cellpadding="2" border="1" ><tr>';
 foreach($attr as $name=>$wert) {
  echo '<td bgcolor="#CCCCCC">'.$name.'</td>';
 }
 echo '</tr>';

 //write datasets
 for ($j=0; $j<$query_layer->getNumResults(); $j++) {
  $result = $query_layer->getResult($j);


  //$shpobj =
$query_layer->getShape($result->tileindex,$result->shapeindex);
  // see note above
**********************************************************************
  $shpobj = $query_layer->resultsGetShape($result->shapeindex,
$result->tileindex);


  $ri = $result->tileindex;
  $si = $result->shapeindex;
  $attr = $shpobj->values;
  echo '<tr id="row'.$si.'" >';
  foreach($attr as $name=>$wert) {
   echo '<td>'.$wert.'</td>';
  }
  echo '</tr>';
  $shpobj->free();
 }
//  $query_layer->close();      // <<REMOVE OPEN AND CLOSE ***********
 echo '</table>';

} // end success
...

Alan,
thanks for the reply, I tried it with getFeature(), but there comes the same
error.
nextShape() works only after msWhichShapes and here I need a rectobj.
But I want to use the script for queryByShape and queryByAttributes too.
Why there comes no array in $attr = $shpobj->values; ?
Any idea?
Sven
