Greetings!
I thought I'd add a little something to a web site, a "tip of the week," and wanted it automated so that if I get hit by a truck (or, more likely, am forgetful), the tip is updated automatically.
I learned enough Perl (read: just enough) to code a script that does what I want it to do. Now the question is: how to get it to run automatically.
I would like the program to be invoked when someone, anyone, hits my homepage. I know little about our environment -- I'm not a developer -- but know that I'm on a Windows box and that we're running IIS. Server-side includes work. Perl for use with forms works. Beyond that, I must offer my apologies for my cluelessness.
I've tried to use the #exec command on my HTML page to invoke the Perl script. Doesn't work. Here's the HTML to my test page: -
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
-
-
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
-
<html xmlns="http://www.w3.org/1999/xhtml">
-
<head>
-
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
-
-
<title>testing perl script from HTML page</title>
-
</head>
-
-
<body>
-
<!--#exec "d:/webdocs/www/irm/training/CGI/tipweek.pl" -->
-
<p>This page is to test to see whether I can run a Perl script from an HTML page.</p>
-
<p> </p>
-
<br>
-
</p><p>Other stuff on the page, including a server-side include below this line.</p>
-
<p>
-
<!--#include file="Tips/currenttip.txt" -->
-
<br>
-
</p>
-
</body>
-
</html>

I do not get an error message, but the files that are supposed to be updated are not updated, so something isn't happening that should be happening.
If I enter the URL for the Perl script into my browser, the script runs; the files are updated.
I don't want the Perl script to create my homepage, as I'm not the only one who needs to be able to edit the page.
Is there some relatively painless way to invoke a Perl script (which doesn't use user input and doesn't need to return anything to the page) from an HTML page?
TIA!

use the virtual SSI tag instead of exec and you need to use the relative url to the script, not an internal machine path:
<!--#include virtual="../CGI/tipweek.pl" -->
see how that works
Thanks! I tried that, and get "Error processing SSI file."
I also tried <!-- #exec virtual="CGI/tipweek.pl" -->, which gives me "Invalid SSI Tag."
And "<!-- #exec "CGI/tipweek.pl" -->", which doesn't give me an error message, but also doesn't update the files.
This latter made me think it might be a files permissions problem, as I've had that problem before (a Perl script apparently running, but no changes appearing in the file that should be changed), so I wrote a little test script to write to the files, and that worked, so the permissions are fine.
I'm open to suggestions! Heck, at this point, I'm desperate for suggestions! I'm at the point where I'm ready to burn black candles and sacrifice a goat, even! Oy!!

I'm open to suggestions!
Check the server errror log and see if there is anything related to the script you are trying to run via the SSI tags. Probably not but it's worth a look. Post the script here if it's not too long or attach it to a post.
Thank you!!
Hi,
try
-
<!-- #exec CGi="CGI/tipweek.pl" -->
-
I got "Failed to execute CGI : Win32 Error Code = 3" in response.
or
-
<!-- #exec CMD="D:\webdocs\www\irm\training\CGI\tipweek.pl" -->
-
And for this, I got "The CMD option is not enabled for #EXEC calls" in response.
That banging you hear is my head against my desk!
The good thing is that the script DOES run when I enter the URL for it into the browser location. At least I have that!
I don't even know who to talk to here about this, but I guess I'm about to find out! :-D
And things aren't looking too good for the goat....!

I got "Failed to execute CGI : Win32 Error Code = 3" in response.
This is just a complete shot in the dark, but have you tried adding the onload="" option to your body tag in your HTML and specifying your Perl script after the equals sign in the double quotes?
ie: -
<body onload="/path/to/perl_script.pl">
-
Just a thought.

Jeff

hehehe.... good try. That would be for javascript. The browser would have no clue what to do with perl code.
The OP just needs to hit on the correct SSI tag and the correct path to his perl code to get it working.

He he, it was worth a shot. I didn't know if it was possible or not. Oh well.
