OK this is a part of the php code I used to add point to shp, notice to use it you have to first give an attribute value (fill a html input) which you will save in a dbf. file, than click on a map to add this point (I was using previously created blank shp. file)ad here is the code:else if ($HTTP_FORM_VARS["CMD"] == "INPUT_POINT"){
$nClickGeoX = GMapPix2Geo($nClickPixX, 0, $dfWidthPix,
$dfMinX, $dfMaxX, 0);
$nClickGeoY = GMapPix2Geo($nClickPixY, 0, $dfHeightPix,
$dfMinY, $dfMaxY, 1);
$oPoint = ms_newPointObj();
$oPoint->setXY($nClickGeoX, $nClickGeoY);$oshpfile = ms_newShapefileObj('C:\Program Files\Apache Group\Apache2\htdocs\data\siedlce\ptk', -2);$dbname = "C:/Program Files/Apache Group/Apache2/htdocs/data/siedlce/ptk.dbf";
$db = dbase_open ( $dbname,2);
$nf = dbase_numfields($db);
$rn = dbase_numrecords ($db);if (ereg("([0-9]+)", $HTTP_FORM_VARS["atrybuty"], $vatr))
{
$def = array($vatr[1]);
}
else
{
$def = array($rn+1);
}$oshpfile->addPoint($oPoint);
dbase_add_record($db, $def);dbase_close ($db);$oshpfile->free();
$oPoint->free();}usig this i never had any problem with overwriting allready added points, no such thing happenedhope this helpsregardsArtur Skalski

Subject: Re: [UMN_MAPSERVER-USERS] How to edit attribute of a selected shape?hi, Skalski,Thanks for the reply. However could you please give more information on this. Maybe an example.The code was working partly ok, the new point can be added, however as I said, it will overwrite the old one. It's attribute was inherited from the old one. I now want to change it's attribute and when I use $poLayer->getResult(0); there seems not point was picked up.regards,Jonathan

Subject: [UMN_MAPSERVER-USERS] How to edit attribute of a selected shape?Dear all,I am tring to create a function which can add comment point onto layer however I got a few problems here:1. the newly added one always overwrite the existing point so there is always only one point in that layer.2. I can not regain the added point.3. how to change the attribute of the added point, say there is one attribue called "Comment".thanks.My code is://Create a new comment point
$ClickGeo = ms_newPointObj();
$ClickGeo->setXY($nClickGeoX, $nClickGeoY);
//printf("ClickGeoX %f<BR>\n",$nClickGeoX);
//printf("ClickGeoY %f<BR>\n",$nClickGeoY);
//Add it to the comments layer
$shape = ms_newShapeObj(MS_SHAPE_POINT);
$line = ms_newLineObj();
$line->add($oClickGeo);
$shape ->add($line);
$poLayer = $gpoMap->getlayerbyname(comments); //get the layer "comments"
$poLayer->open();
//printf("Layer Name: %f<BR>\n", $poLayer->name);
$poLayer-> addfeature($shape); //add the new comment point
//Save the changes
$cmmShapefile = "../htdocs/data/comments";
$objShapefile = ms_newShapeFileObj( $cmmShapefile, MS_SHP_POINT );
$objShapefile->addshape($shape);
$objShapefile->free;
$poLayer->close();
//Task2: Use layer->querybypoint to regain the newly added point and then change it's comment attribut
//Task2.1:get the new added comment point
$poLayer->querybypoint($oClickGeo, MS_SINGLE, 2);
$numResults = $poLayer->getNumResults();
printf("Find point: %f<BR>\n", $numResults);
$oRes = $poLayer->getResult(0);
printf("tileindex: %f<BR>\n", $oRes->tileindex);
printf("SHAPEINDEX: %f<BR>\n", $oRes->shapeindex);
$oShape = $poLayer->getShape(-1,0); //(-1,-1)
print_r($oShape->values); //print the keys of the values array
$comment = $oShape->Values["Comment"];
printf("The comment attribute is ---: %f<BR>\n",$comment ); //display comment attribute
