[Mapserver-users] (2nd) Displaying a layer generated "on the fly" in a map

[Stéphane MOREL]

I do something very similar to you. I query a database build a shapefile 
on the fly and add the shapefile to the mapfile.
Here is a piece of code I use to do this

$lyr_resultat ="/home/mysite/mapserver/carto_bdd/tmp/requete".session_id();
$lyr = ms_newLayerObj($gpoMap);
$lyr->set("name","requete");
$lyr->set("type", MS_LAYER_POLYGON);
$lyr->set("status", MS_ON);
$lyr->set("data", $lyr_resultat);
$lyr->set("transparency","50");
$lyr->setprojection("proj=longlat,ellps=clrk80,no_defs");
$lyr->set("group","Données Galliformes");
$lyr->setmetadata("DESCRIPTION","Fiche(s) d'observation(s) sélectionnées");
$lyr->setmetadata("LYRNAME","Résultats de la requête");
$lyr->setmetadata("RESULT_FIELDS","CODE_OBSE");
$lyr->setmetadata("CHP_BDD","CODE_OBSERVATION");
$class_lyr = ms_newclassobj($lyr);
$class_lyr->set("name","données Galliformes");
$class_lyr->set("color",$gpoMap->addColor(255,0,255));

I hope this could help
