[Mapserver-users] Re: php mapserver interference - usage question..

Sat Dec 27 12:04:17 PST 2003

i think that your problem is you are trying to use the CGI mapserver, 
the main_init.html is not needed when using php mapcript, to use the 
php mapscript you right a php script that loads mapscript, loads the 
map file and then generates the maps and outputs the appropriate html, 
here is an example that is in the mapserver source

-------------------------
<HTML>

<BODY BGCOLOR="#CCCCCC">

<CENTER>

<H1>PHP/MapScript module test</H1>
<P>

<?php
//
// This example opens a regular MapServer .MAP file, renders the main
// Map image (with the default layers enabled), the legend and the
// scale bar, and displays them in the HTML output.
//

//
// Load MapScript module.
//
if (PHP_OS == "WINNT" || PHP_OS == "WIN32")
{
   dl("php3_mapscript.dll");
}
else
{
   dl("php_mapscript.so");
}

//
// Load MapServer .map file
//
// You can download the MapServer demo data from 
http://mapserver.gis.umn.edu/
//
$map = ms_newMapObj("demo.map");

// print $map->numlayers;
// phpinfo();

//
// RENDER MAIN MAP
//
// Note: If you get errors with the saveWebImage() call below, then 
make sure
// that the directory specified by IMAGEPATH in the .MAP file exists 
and is
// writable by the httpd user.
//
$img = $map->draw();

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

//
// LEGEND
//
$img = $map->drawLegend();
$url = $img->saveWebImage(MS_PNG, 0, 0, 0);
printf("<P><IMG SRC=%s>\n", $url);

//
// SCALE BAR
//
$img = $map->drawScaleBar();
$url = $img->saveWebImage(MS_PNG, 0, 0, 0);
printf("<P><IMG SRC=%s>\n", $url);

?>

</BODY>
</HTML>

-------------------------
when this page is accessed it will draw the maps, save them to wherever 
the mapfile says to, and then send the html to the browser to display 
everything, it never uses the main_init.html file
