Hi,

i have a layer in a map file i want to show dynamicly from FORM
parameters choosed by user. This is a POINT layer.
When i do a queryByAttributes on that layer mapserver returns several
shapes but points doesn't appear, nor labels defined in layer.

What do i miss ? Points should be drawn with draw() method ? Is there
any particularity when querying POINT LAYERS ?

I tested the same thing on POLYGON layers and it works fine !
When i turn this POINT LAYER ON points are drawn fine.

Here is my POINT LAYER :

LAYER
  NAME "colPU"
  TYPE POINT
  STATUS OFF
  CONNECTIONTYPE OGR
  CONNECTION "data/etablissements/E-clgpu05.TAB"
  CLASSITEM "ETAB"

  METADATA
    "DESCRIPTION"   "|||Etablissements"
    "RESULT_FIELDS" "ETAB,NOM,DEPT,SECT"
    "RESULT_HEADERS" "|||Numero d'établissement,Nom
établissement,Département,Secteur"
    "RESULT_HYPERLINK" "ETAB"
  END
  LABELITEM "NOM"

  CLASS
    NAME "Collège public"
    TEMPLATE void
    COLOR 139 0 139
    SYMBOL 'circle'
    SIZE 5
      LABEL
        COLOR 139 0 139
        POSITION AUTO
        TYPE bitmap
        SIZE tiny
    WRAP " "
    FORCE TRUE
      END
  END
 
END

Here piece of PHP code :

    $db =& DB::connect($dsn, $options);
  
    # récupération de la liste des établissements
  
    $modele = & new carteModel($db);
    $modele->listeEtabSect($secteur);
    $Lcommunes=$map->getLayerByName("colPU");
    $Lcommunes->set("status", MS_ON);
    while ($item = $modele->getItem()) {

        if (!$item["numetab"]) continue;
                                          
@$Lcommunes->queryByAttributes("ETAB",$item["numetab"],MS_MULTIPLE);
        if (!$nb = $Lcommunes->getNumResults()) continue;
        $resultat=$Lcommunes->getResult(0);
        $Lcommunes->open();
        $nb = $Lcommunes->getNumResults();
        echo "{$item["numetab"]} Nombre de résulats $nb\n<br>";
      
        $Lcommunes->close();
        $shape->free();
      
    $Lcommunes->close();
    }
  
    $db->disconnect();
