Create a polygon layer using PHPMAPSCRIPT

[Delfos, Jacob]

Hi Murat,

A few potential reasons why it might not work:

Your expression does not have quotes around the value:

$class->setExpression("'[ilce_ad]' EQ $ilceadi");
Maybe make it:
$class->setExpression("'[ilce_ad]' EQ '".$ilceadi."'");

If you only class on one attribute, you could set a class item, and make
the expression:
$class->setExpression($ilceadi);

Another possible reason is that you may not save your mapfile, so your
dynamic layer isn't saved in it. You can save it like:
$oMap->save("c:/mapfile.map");

If you are using PHP sessions, you may need to save the state of your
session instead. Try this, and see what ends up being written to your
mapfile by opening it.

Hope this helps...

Jacob
