[mapserver-users] returning mouse click coordinates with PHP

Hi Scott,

try

<?php echo "X= ".$HTTP_POST_VARS["click_x"]." Y=
".$HTTP_POST_VARS["click_y"]."<BR>" ?>

It should do the trick.

Have a look at
http://mapserver.gis.umn.edu/doc/phpmapscript-byexample-howto.html

for demo scripts.
Example 2 should be OK for your needs.

OK, so i have my map being displayed with PHP and Mapscript calls now.  the
initial map is displayed fine, however I can't figure out how to make it
"clickable" so that I can find out which coordiniates have been clicked on.
any ideas?  also pretty soon i am going to want to do more, like panning,
zooming, etc, with PHP.  are there any good demo PHP scripts available to
learn from?  here is my testing.php file:
thanks!

<?php

$map_path="C:\\Program Files\\Apache\\htdocs\\mich\\";
$map = ms_newMapObj($map_path."demo.map");
$image=$map->draw();
$image_url=$image->saveWebImage(MS_GIF,1,1,0);

?>
