[Mapserver-users] box to select point php mapscript

[Sylvain Beorchia]

Hi all,

You don't have to draw another layer to change the style of an object.
Just before drawing the map :


$oLayer = $gpoMap->getLayerByName('foyers');    // foyers is the name of my
layer
$oLayer->set("status", 1);

$sym1 = $gpoMap->getSymbolByName ( "BF125" );    // retreive a symbol from
the symbol file

$class = $oLayer->getClass (0);    // retreive the class of the layer on
which the objects are
$style = $class->getStyle(0);            // retreive the style
$style->color->setRGB(0, 255, 0);    // change the style
$style->set ( 'symbol', $sym1 );        // change the style

$img = $gpoMap->draw();
$url = $img->saveWebImage($gAppletImgFmt, 0, 0, -1);
...

It works very well.
Tell me how u find this code.

Thank u.
Sylvain.
