[mapserver-users] mapfile web object error

[Eric Weisbender]

Steve,

I am trying to pass the error.html page and error massage as a string to Mapserver and redirect the mapfile on the fly.  Below is the code that I assumed would work but doesn't, I get a "Unknown Identifier" error.  Is this possible and if so what is wrong with my code string. <input type="hidden" name="map_web" value="error /data/gis/www/html/error.html?message=[errmsg_esc]>.

Thanks,
EW

Your error HTML page is not a template, MapServer doesn't process it. Rather it just redirects
users to it. As I mentioned you can customize the URL redirected to by passing additional 
information like the error message generated by MapServer.

In your error page you'd have to use javascript or whatever to pluck that info off the query
string and display it on your page. This is totally outside MapServer. If your error page was
a PHP page you could do it there. Does that make sense?
