Ok, since this list has been so helpful and generous to me in the past, here is an exhaustive example. I hope this will finally get you going. Disclaimer: I'm doing this all from memory and w/o testing so there may be a few errors. Setup a map file like this: MAP NAME "Parcel Query" STATUS on EXTENT xmin ymin xmax ymax SIZE 300 300 SHAPEPATH "/data_path" IMAGETYPE png IMAGECOLOR 255 255 255 QUERYMAP STYLE hilite COLOR 255 0 0 END LAYER NAME "Parcels" DATA "parcels" CLASS OUTLINECOLOR 0 255 0 END TEMPLATE "x" END END Setup a web page like this: < < <getLayerByName("parcels"); // Query. $layer->queryByAttributes("", "/".$parcel_ids."/", MS_MULTIPLE); // If you want to avoid errors when no matches are found use the ampersand // in the above statement like this: @$layer->queryByAttributes(); // Render an image and get its URL. $img = $map->drawQuery(); $url = $img->saveWebImage(MS_PNG, 1, 1, 0); $img->free(); ?> < < < <getNumResults() > 0) echo $layer->getNumResults()." parcels found."; else echo "No parcels found."; ?> < < Now that I look at it, the last thing you may have been missing was the mapObj::queryMap() method. Anyhow, I hope this helps. -Abe On Jan 22, 2005, at 10:07 PM, Steve Lehr wrote: Abe: I appreciate the help, still not getting it though. I'm wondering if I need to draw out the map after rendering? I've sceen other posts but no real solutions... I'll start from scratch rather then trying to reuse something I have. If anyone else has a more complete example I'd really appreciate seeing it.

You shouldn't even have to setup a separate layer to show queried parcels (though there are ways to do this). I suggest starting out with one layer that renders queried and non-queried parcels at the same time. Once you get the hang of that then you can do two different layers (if you still even want to). Make the layer like this: LAYER NAME "parcels" DATA "parcels" STATUS on TYPE polygon CLASS OUTLINECOLOR 0 255 0 END TEMPLATE "x" # Must be present to query on (though "x" means absolutely nothing). END The above layer will render all your parcels green outline with hollow fill. Then when you use the PHP code to query it will render your queried parcels red. This assumes you have QUERYMAP setup correctly. -Abe On Jan 22, 2005, at 7:12 PM, Steve Lehr wrote: Abe I've never used the QUERY MAP before, I tried putting it in the layer and it did not like that? My initial layer looks like: I changed my code to pass Pipe delimited. But I'm not quite certian I'm still getting what I need to do to my .map. Thanks for the help..below is the layer repeated my EXPRESSION is trashed I realize.

For the PHP it will be something like this: $target = use_appropriate_string_func_to_conver_semi_to_pipe($parcels); // $target should look like "1|2|3|4" ... where the numbers are the IDs. $layer = $map->getLayerByName("parcels"); $layer->queryByAttributes("parcel_id_field", "/".$target."/", MS_MULTIPLE); Also, don't forget to add the TEMPLATE "x" tag in your LAYER definition. I'm not a RegEx expert, so someone please put me in check if I'm leading Steven astray. -Abe On Jan 22, 2005, at 6:37 PM, Steve Lehr wrote: I'm trying to write some PHP that I can send extents and list of parcels to get it to highlight the parcels.

Now I want to highlight the list of parcels with something like the below. But I have to do something in php to take that ; delimited list and the turn on all the matching attributes. (I belive its a QUERYMAP with MULTIPLE_SELECT) but I'm having trouble getting my brain around what I need to code - might someone have a sample.
