Hi,
If you want to query your dynamic data, you'll have to create a
temporary shapfile. You can't insert attributes in the the inline
feature other than the text. To create a new shapefile, put the shape
object you were adding to your layer features in a shapefile object.
Than to add attributes, you'll have to create a separate DBF files.
Here's a sample code:
$aDbfStruct = array(
array( 'id' ,'N', 7, 0),
array( 'specie' ,'C', 50),
array( 'country' ,'C', 50)
);
$dbfFile = dbase_create( $szFileName.'.dbf', $aDbfStruct);
$shpFile = ms_newShapeFileObj( $szFileName, -2 );
$oShp = ms_newShapeObj(MS_SHP_LINE);
$oLine = ms_newLineObj();
$nPoints = count($aPoints);
for ( $i=0; $i<$nPoints; $i++ )
{
$oLine->addXY($aPoints[$i]['x'], $aPoints[$i]['y']);
}
$oShp->add( $oLine );
$oLine->free();
$shpFile->addShape($oShp);
$oShp->free();
dbase_add_record( $dbfFile, array_values( 1, 'specie', 'country' ) );
dbase_close($dbfFile);
You can also manage everything in a PostGIS, but that's a different world.
