Having hard time adding layers with php

[Assefa Yewondwossen]

Hi There,

 You should use  $layer->set("status", MS_ON) to set the layer on.

 Here is a simple example of something similar to your example.


  $gpoMap = ms_newMapObj("gmap75.map");
  $img = $gpoMap->draw();

  $layer = $gpoMap->getLayerByName ("park");
  $layer->set("status", MS_ON);
  $layer->draw($img);

   $url = $img->saveWebImage(0, 0);
   printf("<IMG SRC=%s WIDTH=%d HEIGHT=%d>\n", $url, $gpoMap->width,
$gpoMap->height);

 hope it helps,
