Hello;
2nd bid !
In fact I think that my first mail has not been practical to read with too
much information. I try to re-ask my question with a new look ! :
I have a problem to declare dynamic layer with color depending of expression
under php mapscript see below.
Please could you help me with an example...
I have tested first with a .map file : It works (you will see the code here
after) and then with a PHP script wich does not work (code is given after).
At execution of the script, it does not display the layer and if I want to
redraw the page, it has an error : (I think that mapserver crashed, and I
need to restart the apache server whith mapserver).
Warning: MapServer Error in msLoadMap(): (é):(0) in c:\my
program\easyphp\www\projet1\pactes-ess\htdocs\mapserv.phtml on line 60
(Rmq line 60 : $gpoMap = ms_newMapObj("pactes-def.map"); )
Fatal error: Failed to open map file pactes-def.map in c:\my
program\easyphp\www\projet1\pactes-ess\htdocs\mapserv.phtml on line 60
If you are curious, you have also the object results (in annexes) for both
cases (.map, and php script).
I) .MAP CODE :
LAYER
NAME numdep
STATUS ON
DATA LIMITE_ADMINISTRATIVE
TYPE LINE
CLASSITEM "NATURE"
CLASS
EXPRESSION "Limite côtière"
COLOR 255 0 0 # dummy color
END
CLASS
EXPRESSION "Limite de département"
COLOR 0 255 0 # dummy color
END
CLASS
EXPRESSION "Limite de région"
COLOR 0 0 255 # dummy color
END
CLASS
EXPRESSION "Limite frontalière"
COLOR 0 255 255 # dummy color
END
END
II) PHP script CODE
$layer = ms_newLayerObj($gpoMap);
$layer->set("name","LIMITE_ADMINISTRATIVE");
$layer->set("type", MS_LAYER_LINE);
$layer->set("data", "lay2");
$layer->setMetaData("DESCRIPTION","Limites administratives des
départements");
$layer->set("classitem", "NATURE");
$fredclass = ms_newClassObj($layer);
$fredclass->set("name","lay2o001");
$fredclass->setexpression("Limite de département");
$fredclass->set("color",10); /* Corresponding to a new color :
128,128,128 */
$fredclass = ms_newClassObj($layer);
$fredclass->set("name","lay2o002");
$fredclass->setexpression("Limite côtière");
$fredclass->set("color",11); /* Corresponding to a new color :
64,0,128 */
$fredclass = ms_newClassObj($layer);
$fredclass->set("name","lay2o003");
$fredclass->setexpression("Frontière internationale");
$fredclass->set("color",12); /* Corresponding to a new color :
128,128,64 */
$fredclass = ms_newClassObj($layer);
$fredclass->set("name","lay2o004");
$fredclass->setexpression("Limite de région");
$fredclass->set("color",13); /* Corresponding to a new color :
64,128,128 */
MANY THANKS FOR YOUR HELP
