[Mapserver-users] How does one create .map files?

[Merrett, Mike]

here is part of some code I am developing for user selection and then
building of map files:  (not all the code is here - and each database entry
Details column contains a complete Layers section (which I copy/paste into
the DB after verifying it works) then I call the processing script (mostly
gmap75) with the name of the map file.

Hope this helps,
	Mike Merrett

function do_build_map_file() {
	
	// get a random non existing file name for the map file
	do {
		$tmpfname = "tmp/TMPMAP". trim(strval( mt_rand( 1, (2^14) *
mt_rand(1,(2^15)) ))) .".map";
	} while ( ! file_exists( $tmpfname));

	$handle = fopen($tmpfname, "w");
	map_put_headers( $handle );   // put the headers (i.e. everything
above the layers in a normal map file

	//layers are selected -- now build the map file
	$link = dbx_connect (DBX_MYSQL, "localhost", "mysql",
"MapServer_Layers", "MapServer_Layers")
	 			or die ("could not connect");

	foreach( $_POST['layers'] as $a_Layer ) {
		$sql = "select Details"
			."   from MapServer_Layers "
			."   where LayerName = '" . $a_Layer ."'"
			;
		$result = dbx_query($link, $sql, DBX_RESULT_INDEX |
DBX_RESULT_INFO );

		fwrite( $handle, $result->data[0][0]);
		fwrite( $handle, "\n\n");
	}
	fwrite($handle, "\n\nEND");
	fclose($handle);

	return ($tmpfname);
}

well,
	based on Ed theory, i think some php Smarty templates and
phpmapscript 
can do the job well and easy.
	i'll try this and post some news.

	good luck.
