Setup problem

by dvdj (Initiate)
on Sep 05, 2004 at 12:56 UTC ( #388599=perlquestion: print w/replies, xml ) Need Help??

dvdj has asked for the wisdom of the Perl Monks concerning the following question:

Can somebody please help me!!

I am looking for Monk guidance for the first time so apologies in advance if I haven't followed protocall with the following submission.

I'm having an addressing issue with a PERL script i'm trying to use on my site. I'm new to learning PERL, so don't have the expertise to write a script that directs the content of a form to my email address and sends an automated reply to the submitter, with a thank you page. So I found a script online and am trying to get it to work on my server. I know I have included alot here! But i do so in the hope that a thorough look can be given, as I am at a real loss as to what I may have configured wrong. Many thanks in advance for any help.

The set up on the server is as follows:

The contact page contains the following form code. Please note i'am aware that i have additional fields that are not included in the PERL script which i intend to address once it's working. I hope I'm right in thinking that this wouldn't stop this script from working. But i have renamed the appropriate fields to match the scalars listed in the script.
<form action="/cgi-bin/AlphaMail.pl" method="POST"> <table width="100%" border="0" cellspacing="0" cellpadding="2"> <tr> <td>NAME</td> <td><input type="text" name="Name" class="formAreas"></td> </tr> <tr> <td>PHONE NUMBER</td> <td><input type="text" name="telephone" class="formAreas"></td> </tr> <tr> <td>EMAIL</td> <td><input type="text" name="Email" class="formAreas"></td> </tr> <tr> <td>COMMENT/ENQUIRY</td> <td><textarea name="Message" cols="15" rows="4" class="formAreas"></te +xtarea></td> </tr> <tr> <td>PLACE OF EXERCISE</td> <td><input type="text" name="plcOfExercise" class="formAreas"></td> </tr> <tr> <td>HOW DID YOU HEAR ABOUT TRUE VITALITY</td> <td><input type="text" name="howDidUHear" class="formAreas"></td> </tr> <tr> <td><br> <input name="resetVitality" type="reset" class="formAreas"></td> <td><br> <input type="submit" class="formAreas"></td> </tr> </table> </form>

    PodMaster is right to steer you away from this script, but he doesn't say why. I'll describe several of the warts on that thing.

    On its coding standard, this script is very primitive. It uses subroutines as a kind of simple substitution macro, taking no arguments and acting only through global variables. The subroutines occasionally return some useful value, but the caller never makes any use of the retrun values. Error handling is done with exit, which is mighty presumptious of a subroutine. It is uncatchable and prevents any more gracious message to the user.

    The ReadParse routine attempts to do what CGI.pm actually does for you automatically. Not taking advantage of that core module is a red flag. As it is, ReadParse does not appear to work. It seems to try to parse both raw posts and query strings in the same way -- and wrong for either.

    CheckReferingURL is easily spoofed and some browsers don't accomodate it well. It is well-known that HTTP_REFERER is not useful for security or use restriction.

    CheckEmailAddressFormat fails for legal addresses (like dvdj@localhost). This is a notoriously difficult function to implement, and you're usually just as well off without it.

    Follow PodMaster's advice and try the nms archive.

    P.S. we spell it "Perl" or "perl".

    After Compline,
    Zaxo

      Thanks to all of you, the problem is finally now resolved. Thanks Podmaster for your link to the nms archive the script there was fantastic. As it turned out in the end, It wasn't a script or addressing issue. It was the chmod execution permissions that ihadn't set correctly. Many thanks again to all of you for your speedy and helpful responses.

      TFmail is definitely higher quality code. But are you sure it has the auto-reply feature the poster wants? I couldn't find that feature just now.
        *Yawn* I said After that you gotta read/configure TFmail and it will do what you want. Do I have to be sure? Could you have made sure?
        confirmation_template - If this field is set then it must be the name of an email template that will be u +sed to send a mail back to the user confirmi +ng their submission. CAUTION: since the us +er could give any email address (not just t +heir own) and submit repeatedly, there is a r +isk that some nasty person will use this to mailb +omb a third party. Only switch this on if y +ou really need it. Template directives tha +t depend on user input will be disabled fo +r this template, so that this feature can't be +used to send SPAM. Default: no confirmation ema +il.

    Okay, I see several possible problems here. First, though, some protocol issues:

    1) protocol, not protocall
    2) Perl, not PERL
    3) a lot, not 'alot'. (You wouldn't write 'alittle', would you?)
    4) You did include an awful lot of stuff from the script, but no information about the system, nor about where you got the script. Those would have been helpful. You also didn't say what the script is doing. I assume it isn't working, but are there any error messages? Does it send mail, but it's empty? What exactly is the problem?

    We really need the answer to 4) before we can help you. What happens when the form is submitted? Also, if you log on to the Web server via command line, what happens if you do:

    perl -wc ./AlphaMail.pl

    Lastly, let's confirm a few things for you:

    1) /usr/sbin/sendmail is correct for $MailProgram.

    2) As long as you used only WordPad or Notepad to edit the file, your mailer should not have done anything strange with it. If you're worried about newlines, log on to the Web server via SSH (or - egad! - Telnet) and run pico -w AlphaMail.pl or, if they don't have pico, try nano -w AlphaMail.pl. Once you have the file open, press Ctrl-O, Enter, Ctrl-X. If you had any newline/carriage return weirdness, it'll be gone.

    3) All of the other variables in the 'configurable' part of the script are just strings used to construct the messages, so it doesn't really matter if they're correct or not.

    So the only thing that comes to mind is, if you log on to the Web server and run /usr/sbin/sendmail -t, what does it do? If nothing appears to happen, but you don't get your prompt back, that's probably good. (Press Ctrl-C to abort sendmail.) If not, what happens instead?

    Also, what did you use to FTP the file up to the server? Windows' command-line FTP util? Did you remember to use binary mode (type 'bin')? If not, you should send the file again (just overwrite the previous copy), making sure to use binary mode.

    --J

    Update: Added suggestion re: binary mode FTP.

      Your advice about ftp binary mode is wrong. When you transfer a win32-ish text file in binary mode, the splatline is seen as "#!/usr/bin/perl\r". There is no such executable file, resulting in a "File not found" error. ASCII mode does line end translation and prevents such errors.

      After Compline,
      Zaxo

        This is only true if the file was originally created on a Win32 system. Wordpad (and maybe Notepad) can correctly edit a UNIX-style text file (sans \r) without mangling it, as the original script itself suggests, and the author says she did.

        I've have no end of trouble transferring things in ASCII mode. The only time I've used any mode other than binary was when I sent a text file to a VAX using EBCDIC mode (bleh!). If I have to do some file cleanup - whether by using the 'pico cheat' or a cleanup Perl script - that's fine, but I'd rather do it myself than have my file transfer program doing things for me.

        Which is why I use Linux and write my own Perl code. :-) I don't do everything myself, but I want the option.

        NOTE: I sent e-mail to the author of the original post shortly after she posted it. No reply yet, and AFAIK, she only came back to the site once or twice to see if there were any answers.

      You wouldn't write 'alittle', would you?

      You'd be surprised how many people do.
