If you use pdflib to print, something like this (should do better ...):
1)gmap75.phtml:
<a href="#"
onclick="window.open('printSetup.php?PHPSESSID=<?=session_id()?>&ext=<?php
$dfMinX = $gpoMap->extent->minx;
$dfMaxX = $gpoMap->extent->maxx;
$dfMinY = $gpoMap->extent->miny;
$dfMaxY = $gpoMap->extent->maxy;
$ext = array($dfMinX, $dfMinY, $dfMaxX, $dfMaxY);
echo serialize($ext)?>
&layerNums=<?php
$j = -1;
$layerNums = array();
for($i=0; $i < $gpoMap->numlayers; $i++) {
$iLayer = $gpoMap->getLayer($i);
if($iLayer->status == MS_ON || $iLayer->status == MS_DEFAULT) {
$j++;
$layerNums[$j] = $i;
}
}
echo serialize($layerNums);
?>', '', 'width=250,height=100')" >
<img alt="print" src="images/print.jpg" align="center" border="0">
