sure
umm...
here

http://www.footballjoint.com/Draft/team1.html

(if ya enter info you'll get a 500 error)
I took Matt's free links script and stripped the (a href) tags out of the script so it won't post values as a link
added in some html table and refresh tags to the html form page and...that's about it
after I removed those, I used an <li>(orderred list) tag as my counter instead of <a href like he did. But I'd swear it's 90-95% the very very same script. The 500 error is solely caused by that line. Everything is kewl otherwise.
And thanks for your time
here's the code:

# Get the input
read(STDIN, $buffer, $ENV{'CONTENT_LENGTH'});

# Split the name-value pairs
@pairs = split(/&/, $buffer);

foreach $pair (@pairs) {
($name, $value) = split(/=/, $pair);

$value =~ tr/+/ /;
$value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;
$value =~ s/<([^>]|\n)*>//g;
$value =~ s/<//g;
$value =~ s/>//g;
$FORM{$name} = $value;
}

if (!($FORM{'title'})) {
&no_title;
}

Seem to be working now, (http://www.footballjoint.com/Draft/team1.html)
and the script looks perfecly ok,h

**FJbrian** · Jun 18, 2002, 10:59 PM

I was playin' that's why there's no 500 error
same prob
please notice on Team 12 there are many of the same values
that is the line of the script I'm referring to
it doesn't match the value and send them to the repeat url function
a repeated value should not be allowed

**Calilo** · Jun 18, 2002, 11:06 PM

maybe the problems is that the $filename is an empty var, you should add something like this to see if that is the problem

open(FILE,"$filename") || die "couldnt open $filename in read mode";

always make sure to use those die expressions, very very importants ones,

**sir pannels** · Jun 19, 2002, 07:53 AM

calilo you missing > or >> in there?:confused

**FJbrian** · Jun 19, 2002, 10:47 AM

the filename variable is the real long location of the html page like
awholebunchofstuff/public_html/Draft/team1.html
basedir is ...
I didn't post those 4 lines of code nor
/usr/bin/perl
just to be safe

I am 100% certain the problem is that line I mentioned
In the meantime, I wrote someone else with the code and he responded "check line #"...the line I mentioned.
I don't have 200 bucks to pay him to fix that one line.

**sir pannels** · Jun 19, 2002, 11:09 AM

how you know its that line? if the logs or error is telling you..example its line 30 then most prolly its line 29 amd of ot says 83 its prolly 82 and so forth

sir p

**FJbrian** · Jun 19, 2002, 11:36 AM

How?
I changed it line by line checking every single time to make sure it still worked
that's where I got stuck

this isn't going so well
I guess I'm a bad 'splainer
I don't know PERL
forget that jazz above, try again
I want the script to go to repeat URL function if what's being submitted has already been submitted.

if $FORM{'url'} matches url's in document already
&repeat_url

How's this for wording a question

Can you replace my
ENGLISH (matches URL's in document already) with PERL?

**amy2go** · Jun 19, 2002, 06:46 PM

Decided to give this one a whirl.

Your code:

if ($line =~ /\<li([^]+)([^]+)/) {

should be:

if ($line =~ m/\<li([^]+)([^]+)/) {

Add the m in front of the forward slash. The m stands for match; s stands for substitute, and tr stands for transliteration (or translation). Hope this helps..didn't test it.

**FJbrian** · Jun 19, 2002, 09:27 PM

that didn't work
well the page still posts and functions it just doesn't match up and go to repeat URL function

see

http://www.footballjoint.com/Draft/team1.html

scoobydoo yogibear are on many teams

thanks for trying though

**amy2go** · Jun 20, 2002, 10:48 AM

I'm still new to Perl, but I haven't read a file the way that you have this set up, not to say that it can't be done that way. Here is how I have read a file in one of my Perl scripts - and maybe you can modify it to suit your needs:

open( FILE, "filename.txt") or
die("The file could not be opened");

while($line = <FILE>){
chomp($line);
#code to implement on each line
}

Other than that, maybe you should look at your regular expression: /\<li([^]+)([^]+)/

Minus the two forward slashes, which contain the regexp, you have a backslash, so the < will be taken literally, and the li will be also. That leaves <li
Then you have opening parenthesis ( , which signifies a group. Then you have brackets [] , which says you can have any one of the characters inside.
Then you have caret ^ , which means you're going to examine a string starting at it's beginning.
Then after the brackets you have a plus sign + , which means one or more of whatever the previous item was.
Then you have the closing parenthesis ) of the group.
Then you repeat that group.

Problems with this (that I can see) is:
1. You never closed your <li> tag, as in \>
2. You never specify what character is allowed in the brackets; you only signified a beginning of a string.
3. Usually the caret would be used only once at the beginning of the regexp as soon as you type the forward slash, as in /^

Best of luck,

Amy
