[mapserver-users] RE: Highlight

[Moen, Paul T.]

If the database that you are querying has the same attributes as the shape file, you can query the Layer that points to the shape file and display the highlighted results on your map.  I know nothing about GeoMOOSE but I know it can be done with php-mapscript.

Regardless of what you are using, you need a map file layer for the shape file with the parcels.
You will then need to use php-mapscript to query that layer with something like
$map = ms_newMapObj(PATH TO YOU MAPFILE);
$qlayer = $map->$map->getLayerByName(NAME OF PARCEL LAYER);
$qlayer->queryByAttributes('PID','PID IN (1, 2,7,9,23,87)',MS_MULTIPLE);
You will then need to create the output image from query using something like
$img = $map->drawQuery();
header('Content-Type: image/jpeg');
$img->saveImage("");

I can't give you specifics without knowing how GeoMOOSE works, so the best thing is to look at the documentation for GeoMOOSE if that is what you are using.

Dang I misspoke...I am sorry...

I am querying a Database for records, these records have a PID (unique Number).
These are the records that show up in the Table.

As this happens I have to take the results and run the query against the parcels to get the features in the Shapefile, then highlight..

If that makes any sense...

If I am in a PHP file and have the records returned from the query (database)...what would I have to do next to take those records and run a query to highlight the parcels (PID to PID)?

Can all of this be accomplished in the PHP file?

Thanks...and sorry for my ignorance...

Set the mapfile QUERYMAP style to highlight http://mapserver.org/mapfile/querymap.html.   Draw the map using drawQuery() instead of draw().

$img = $map->drawQuery();
header('Content-Type: image/jpeg');
$img->saveImage("");

It returns the records into a table, which I then have the option to zoom to.

I am looking for a bit more....after I run the query (php) I want the returned records to highlight in the map...
I can get the Unique identifier but don't know if I can write some code in PHP to highlight those features

I don't even know where to start here...

The query and returning records into the table, as well as, the zoom to work great...just need the highlight part

Thanks

Any way to highlight a feature in my map in PHP?

I can grab a unique identifier but can figure out how to highlight it...

THanks
