[mapserver-users] php mapscript

[Worth Lutz]

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
