RE: form user interface issue
Okay, I think that I'm getting closer. I've condensed my code so that it is
a little clearer.
form method=post action=2003springcontest.pl onSubmit=return
submitIt(this)
input type=text name=check_email maxlength=60
input type=submit name=choice value=Check
/form
perl decision making code:
if ($choice eq ) {
checkemailform(); # displays form
}
elsif ($choice eq check) {
checkemail(); # inserts the data
}
Are you suggesting this for the form?:
form method=post action=2003springcontest.pl onSubmit=return
submitIt(this)
input type=text name=check_email maxlength=60
input type=hidden name=choice value=Check
input type=submit value=Check
/form
I took the name value out of the submit input tag and included a hidden
field that includes a the name choice and the value check, which is what I
logic code is looking for. Do you think this is the correct path?
Thanks in advance. I appreciate your input.
Thanks,
Andrew

That form probably has a submit button that has a parameter name=
The script might be checking for that param('...').
If the form is submitted by pressing the button, that parameter from the
submit button is sent to the server while if the form is submitted by
pressing enter from another form field, it is not, so the script will fail
when checking for it.
The solution is to put another hidden field like input type=hidden
name=... value=... and remove the name=... parameter from the submit
tag.

Subject: form user interface issue
I have a form that I am using to add data to a mysql database table. I am
using a .pl scrtipt to generate the html. I am using cgi.pm and param() to
insert the form data. And, I am using to the printHTML; function to
display my forms within the .pl script. The problem is that when the user
completes the form and hits the enter key (as opposed to the mouse to submit
the form), the form goes blank and nothing happens. However, if a user uses
the mouse, everything works fine.
Please let me know what you think the problem is. Any assistance would be
greatly appreciated.
Thanks,
Andrew

self refreshing web page question

RE: Forcing a refresh from within a CGI script
Rob Dixon wrote: Hi all. I'm in the process of modifying an existing CGI script. There is a page of HTML which has an anchor to the script which, when run, modifies the HTML file which linked to it and redisplays it. At present this is done by returning just the header line Location: http://www.domain.com/referrer.htm to the client after modifying the file. Firstly, I'm not at all sure if this is the preferred way to force a refresh, and secondly it doesn't always work as the client browser believes it has a valid cached copy of the page and refuses to reload it. Can someone help me towards a better solution? To prevent the client from using its cached copy, you'll need to have the server send an Expires header with the .html page. This can be accomplished by adding meta http-equiv=Expires content=0 in the head section of the .html file. (RFC 2616 specifies that clients must treat an expires value of 0 as already expired.) -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Removing all \n in a text file.
By writing it this way:
open(OUTPUTFILE, . $outputFile);
the script thinks that you are trying to open a file called
Out_input2.txt
with the greater than sign actually being part of the file name. But what
you want to do is open
Out_input2.txt
for writing, in which case the greater than sign, which means open this
file for writing, needs to be contained inside the quotes.
open(OUTPUTFILE, $outputFile);

Hi Scot,
Thanks for your help. I am not sure in what way this code differs from
my previous one. Is the change in the open statement significant wrt to
how \n are read and written.

RE: The very un-useful 'premature end of script headers' error message
Not really. If your form allows uploads, your form allows uploads. That's where DoS comes into play. Disguising the location of your code is a start, but you still have to figure out what you're going to do if someone tries to paste rogue code into your form or hit you with an obnoxiously large upload. CGI.pm does have some provisions for this built in, and I highly recommend its use for web forms as opposed to home-grown CGI. I believe many others on the list recommend the same Scot R. Well, does it help that this code snippet we have been looking at is not in a file with a .cgi or .pl extension, but in a .pm file being used by the actual .cgi file that people would be posting to.

Re: Why this perl error?
I guess it is a Perl 5.8 bug because this didn't happen in Perl 5.6.1. Or, ... it might be a DBI module error, but I don't think so.

Hi teddy, I ran into this exact same problem (on win2k using DBI and fork()) and eventually gave up. Alas. Someone more knowledgable will have to give us a definative answer but my primitive understanding is that fork() typically uses the system's implementation of the fork() command and that Windows doesn't have one :( So, efforts have been made to implement it at the interpreter level with limited success.

Re: portability question...IIS Vs. Apache
IIS thinks the CWD is the root directory of the script alias. Just set
up a script alias that points to the directory where the cgi actually is
and you'll be fine.
Peter Kappus wrote:
Hey all,
Anyone move scripts between IIS and Apache or need to write scripts that
work on both? The problem I'm facing is that IIS reports the current
working directory (CWD) as the root dir of the application as defined in
the IIS control panel while apache reports the CWD as the actual directory
of the script file itself.
This is a problem when including other files/modules...
For example, to include /myApp/func.pl from /myApp/index.pl:
require func.pl;#works fine in Apache but not IIS
require /myApp/func.pl; #works for IIS
ditto for modules:
require myMods::myModule.pm;#works in Apache
require myApp::myMods::myModule.pm; #works in IIS
aarrggh. I'd rather not add a big block like:
if(-e func.pl){
require func.pl;
}else{
require /myApp/func.pl;
}
at the top of every file and I don't even know if that would work...
Anybody got a more elegant solution? (other than dump IIS ;-)
Thanks!
