Hi all,
I am currently developping a simple Mapserver aplication. I need to do the
folowing: create a div in my index php where i will have checkboxes
representing my layers. I want the user to be able to set my layers visibility
(status) on or off. I have the folowing html
<? include ('rosia.php'); ?>
<html>
<head>
<title> Rosia Montana Environmental Mapserver</title>
</head>
<body>
<center style="color: rgb(42, 29, 89); font: bold 14pt ;" ><b> Rosia
Montana Gold Corporation Environmental Mapserver</b></center>
<hr/>
<form METHOD=POST ACTION="<?php echo $HTTP_SERVER_VARS['PHP_SELF']?>" >
<div name="harta" id="harta" style="position: absolute; top:
8%; left: 1%; width: 63%; height: 73%; border: 3px solid black ">
<INPUT TYPE=IMAGE NAME="mapa" SRC="<?php echo
$image_url?>" style= >
</div>
<div name="navigare" id="navigare" style="position: absolute;
top: 8%; left: 65%; width: 32%; height: 8%; border: 1px solid black ">

</div>
<div align="center" style="margin-top: 6px"> <INPUT
TYPE=IMAGE NAME="scara" SRC="<?php echo $scara?>" ></div>
</div>
</>
</body>
</html>
how could I achieve this through phpmapscript?
i think that the logic should be
if the checbox is checked $layer->set("status", MS_ON)
else $layer->set ("status", MS_OFF)
i undestood it can be achieved only with not default layers
nay suggestion is welcomed
