Re: real beginners stuff
Jimmy,
Sorry I had not read this post before I replied to the other.
You need the permissions on a folder to be readable and executable in order for people
to read what
is in that folder period (not just execute scripts). So your folder needs to be
permissions 755.
Your script must be readable and executable in order for somebody to run your script,
so again
permissions 755.
3 digit permission assignments:
- first position is the file owners permissions
- second position is the file groups permissions (permissions for everyone in the
group of the user
who owns the file)
- third position is the permissions for the whole world.
how to get a permission digit:
4 = read
2 = write
1 = execute
Add all of the allowed permissions to get the permission digit
example, 7 allows anything, 6 is read and write, 5 is read and execute.
Directories are kinda strange because you have to be able to execute them in order
to get a
directory listing.
Regards,
David

Re: Post to a second CGI script
Jim, My recommendation is to write a session file on your server and pass the session id around with the browser variables. Now whether you use cookies, get or post to pass the session id, you don't have to be passing the actual username. If you don't want to have the user see the session id, put it in a cookie, and check to see if the cookie was created, if not, then send it via a form with post. If you want to be really sneaky about it, get your session id, then encrypt the id before giving it to the individual, so if they modify it, the decrypted version of what they pass back will not only not match theirs, but it cant match any one else's session id because it likely will not translate into a valid session id format.

Re: regex - problem

Did you get the problem fixed? Yes it was because you did not escape your . when
you wanted a .
instead of an any character.
..[a-zA-Z]{2,3} will match .abc, but it will also match abcd but \.[a-zA-Z]{2,3}
will require
that the first character this part of the regular expression matches is a period, not
an any

Re: Couple of newbie questions
Kerr, Apache spawns a child for each web connection, while doing this, if a cgi script is called, it pulls a copy of the script into memory, executes it. Ways to debug: Yes Apache does have an error log, search your httpd.conf for ErrorLog. That like specifies where Apache will write any errors including errors returned from perl. If you use tail -f /var/logs/error_log (of course replace that with where your error log is), you will be able to watch the log incase any errors pop up. This is very very useful while developing. Other methods tricks are print STDERR \$var = $var\n; This way you can get the values of certain variables when ever they are in question. If you want it to be easier to see and your script is not live, you could even simply print your values to STDOUT (print uses this by default so simply print stuff would do this). Keep in mind, if you have not printed a content-type before attempting to print some debug to the browser client, you will get an Internal Server Error. If you are getting an Internal Server Error and you know that you are printing a valid content-type, this means there are probably other errors in your script (usually syntax). Watch the error log for these.

Re: Counting the time with fractions of a second. The solution!
Teddy, Because times is a perl function, not necessarily a var. Here's what one of my perl books has to say about it: --- The times function returns the amount of job time consumed by this program and any child processes of this program. The syntax for the times function is @timelist = times As you can see, times accepts no arguments. It returns a list consisting of the following four floating-point numbers: - The user time consumed by this program - The system time consumed by this program - The user time consumed by the child processes, if they exist - The system time consumed by the child processes, if they exist --- So there you have it. When you are calling $begin = (times)[0]; You are calling times function and specifying that you only want to get back the first element of the returned array, which happens to be the user time consumed.

Re: Why Premature end of script headers?
Probably your web server is timing out the request and killing your
script. Web servers don't like to run long-running processes like
this. Perhaps you can fork off a child and have the child take care
of it.
Another solution is to have something like the following in your loop:
--
local $|=1; # print things right away (no buffering)
# $ltime and $ctime should be defined before the loop
$ctime = time();
if ($ltime ne $ctime){
print . ;
$ltime = $ctime;
}

Then the browser does not time out because it continually gets information, so it
simply prints
another period to the browser every one second that it is working. This can help you
know its still
working.

Subject: Why Premature end of script headers?
Hi all,
I've made a little script that takes the lines from a file,
removes the
dupplicate lines and prints the result to a new file.
I've read the original file line by line because it is a big
file (over 7
MB).
The problem is that after printing almost 10% from the
original file into
the new file, the script dies and the only error I get in the
log file is:
[Mon Jul 15 14:44:48 2002] [error] [client 127.0.0.1] Premature end of
script headers: clean.pl
I've checked the original file to see if there are some
strange characters
in that line, or in the next one, but I haven't found
something that might
cause that problem.
Please tell me why is the script dying only after it runs for
a few minutes,
and after writing over 11000 lines, and not from the
beginning, if there is
a problem with the script.
Can you find any problems with my scriptt?

Re: Why Premature end of script headers?
Yes, your right.
It seems to me there has got to be a more efficient way to accomplish what is
being attempted.
Right now, the solution is making a copy of the file, then checking every line of the
original
against every line of the copy. This method becomes exponentially more processor
intensive for
additional lines to the file. Perhaps a recognize would be to loop through the lines,
give them a
line number, and write them to a copy. Then sort the copy alphanumerically, then loop
through the
copy checking one line against the next, and if the next is a duplicate, through it
away, and
continue checking it against the next until they are not the same. As soon as their
not the same,
take the line that is not the same and begin checking it against the next line. So on
and so forth.
Because every like line will be right next to each other, you don't have to check each
line against
every other line, just the ones next to it. After your done eliminating the
duplicates, sort the
file again by line number (this only if its necessary to keep them in a certain
order), and your
done. Granted this method requires that you find some efficient manner of sorting the
lines in
large text files, but if somebody knows of something that can do this, viola.

David

True. But there are two possible downsides to consider:
1. It ties up a server process for an extended period.
2. The server will kill the CGI script if the client goes away

Re: Executing cgi from perl script
Shane,
Um, first of all, you probably shouldn't be modifying your cgi script dynamically,
Lots of room
for error. What you should be doing instead is perhaps updating a text file that the
cgi script
will open and use as its Insert content here content.
Next, how is the template.cgi being called? Is it an include in an html page or
something? Are
you opening it with another cgi script? More information is needed to help you finish
resolving
this problem.

David

Subject: Executing cgi from perl script
Hi,
I want to execute a cgi script from a perl script that first updates the cgi
script. The basic code I'm using to open and update the file is:
print Content-type: text/html\n\n;
open RESULT, template.cgi;
while (RESULT) {
s/Insert content here/$output/g;
print;
}
close RESULT;
The cgi file calls the header and footer for the application. When I run it
like this I get a web page with cgi code in the header and footer and the
correct content. How do I execute the cgi file after updating it? I'm on the
right track?
Thanks
Shane

Oops, let me make one small revision to my code:
if (exists($form_vars{$name})) { # if this is the first of this form input name.
should be
if (!exists($form_vars{$name})) { # if this is the first of this form input name.
Sorry about that all.

Connie,
; has no problem, why you would like to escape( \ )it ?
I know that = and ; don't have a problem, I escape them because I escape every special
character,
that way I don't have to worry about what I do and don't need to escape. I know, bad
habit (old
habits die hard).
Besides, if you 'next' it if that $variable is not a name=value pair,
so is that mean this var will throw away ?
This is a safety net incase somebody types in the url with something like this:
http://www.domain.com/test.cgi?namea=valueanamebnamec=valuec
You don't try to split on = when there's not an = in there.
Trust me, I've put a lot of thought into this code over the last 2 1/2 years. I don't
particularly
care for CGI.pm either (but we wont go into that), I wrote my own called Form.pm which
I hope to get
up on CPAN one of these days. It handles both GET and POST as well as command line
parameters
(Along with post [MIME], I also accept files). It also works on Linux and Windows.
Its also much
faster than CGI.pm because its strait to the point, the only thing its intended to do
is retrieve
data and give it in a useable format.
Hmmm... what is this purpose ? $name is probably going to be a
var's name, how come it goes with a blank ? and with an assumption
that the $name is coming as a URI escaped string ?
Well that's exactly what we are doing, unescaping a URI, we just happen to split it
into name and
value before unescaping it (this is important incase somebody has a %26 in their name
or value).
Just hard to imagine how come a request coming with same name.
Aren't we supposing the later come value with same name will overwrite
the first one ?
How about this instance:
http://www.domain.com/test.cgi?name=joeprefscheckbox=YesEmailMeprefscheckbox=YesPhoneMeprefscheck
box=YesSnailMailMe
This is a scenario when you want all of the multiple values with the same name, so you
need to put
it into an array instead of a scalar.
I knew right from when you mentioned $ENV{'QUERY_STRING'} That you were intending to
write a form
input parser. Well if you are only going to use get, consider the following:
my @variables = split(/[\\;]/, $ENV{'QUERY_STRING'});
my %form_vars;
foreach $variable (@variables) {
next if ($variable !~ /\=/);
my ($name, $value) = split(/\=/, $variable);
$name =~ tr/+/ /;
$name =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack(C, hex($1))/eg;
$value =~ tr/+/ /;
$value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack(C, hex($1))/eg;
if ($value ne ){ # remove this if statement if you want to keep pairs where the
name has an
empty value
if (exists($form_vars{$name})) { # if this is the first of this form input
name.
$form_vars{$name} = $value; # setting the variable the hash with the name
to the value
} else { # for repeated times in with the same form input name
$form_vars{$name} = [($form_vars{$name})] if (ref($form_vars{$name} ne
ARRAY)); # make
this an array if this its not one yet
push(@{$form_vars{$name}}, $value); # adding the next element to the list
}
}
}
This essentially gives you a hash with name value pairs for every single value
names, and an
array ref for every name that has multiple values. Basically, it gives you anything
that was sent
(optionally even name empty value sets assuming you remove the if statement around the
assignment
block).
Eventually when I get it on CPAN, it will be a simple as
use Form;
my %input = Form();
Anyway, good luck,
David

You need to either .htaccess protect your destination page, which makes your logon form a waste of time, or you need to output your html from the cgi-script that does the password checking. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Form.pm
Janek,
Yes, I could have shorter lines at the cost of the number of lines. Personally, I
like taking
things like this:
--
if ($thisvar eq $thatvar and $thatvar eq $anothervar){
print all three were the same\n;
}
--
And making them this:
--
print all three were the same\n if ($thisvar eq $thatvar and $thatvar eq
$anothervar);
--
It just seems to me that a lesser number of lines the interpreter has to trudge
through, the better.
I guess for me, multiple lines are more of a burden than long lines.
There are a few small blurbs of code in Form.pm that are exact copies, but the two
sections of code
only have about 5 lines that are exactly the same which are intertwined with others
that are not. I
actually spent a few hours looking this up and down attempting to discover if I could
eliminate
additional code by putting it in another sub. I at length came to the conclusion of
what I
currently have.

Nowadays we print newspapers with very big dimensions.
Why do we still use columns ??
Because we can better read it that way.
And readability is the mose important part of a computer program.
Even without the aspect of readability long lines of code are an alert signal.
It's like having a description of something with long and difficult sentences.

There's nearly always a possibility to reduce the line length.

The trick is like in real language.

in a sequence of simpler ones.
Reduce also doubled code

Re: Including External Pages
Of course, and usually that's the way I do it. Basically, if you put the local
statement in a
block, then the scope of the change to the system variable is only effective inside of
the block.
Just like if you did this:
--
{
my $cool = stuff;
print qq^\$cool is still in scope and equals $cool\n^;
}
print qq^\$cool is no longer in scope so it is undefined, but if you tried to print
it, you would
get $cool\n^;
--
The difference is that my makes a new lexical variable, where local will make a copy
of a current
variable which is already in scope for use inside the block (including system vars and
globals).

You really didnt need to explain yourself in relpy to my post.
Here is a snip from the op's original post:
Kyle Babich [EMAIL PROTECTED] wrote in message

What would I use to include external pages in my script? (like if I
wanted
to print the contents of faq.txt or log.cgi in my script)
I was providing the op with an alternative way to get identical results.
Sometimes your solution is better, for the reason that you stated, so that
the info could be filtered.
Sometimes the code I provided is better, for example the file is very large
and it is best to avoid loading the data in to memory.
Sometimes there are other solutions that are better for other reasons.
The point I was trying to make was how print() takes a list of data and not
just a simple scalar, a key concept for new perl programmers to understand.
It probably took me months to understand it. It had nothing to do at all
with your solution.
But since your solution involves turning on slurp mode I do suggest
explaining what that means, and what side effects it could have to the rest
of the code. For instance, if your example is used, and later on in the
program in the same scope I say:
while (OTHER_FH) { # oops!
It is probably going to confuse someone. Again, someone is back in the
newsgroup trying to get help tracking down a very difficult-to-track bug.
Probably every example in the docs that show modification of $/ in action
have the corresponding code wrapped in a block, i.e.
{
local $/ = undef();
$_ = FH
}.
Quick quiz: can anyone explain why?

Duh, I should have thought of that one.
So the only time this would be an issue is if somebody not knowing that ; can be a
element delimiter
creates an href with a ; in the name or value. Ok, that solution works for me.

Form.pm
Well, I'm a little bit behind
schedule because the home page for Form.pm just got erased (long story).
Anyway, I just setup a backup system on my server now so I'll have a weeks worth
of daily backup's (ya, I know I should have had this before). But attached
are the main functions of Form.pm there are three functions I left out.
One is Form,another is read_net_input and the last one is
write_file. By the way, do I have any reason to believe that somebody may
run off with my code and claim it as their own?
I was about to just include a
link to the home page for Form.pm in this email, but now that its gone I'm not
going to do that. I'm hoping a buddy of mine has a cached copy.
I have yet to implement the file
size limitations, file upload limitation, and the getwith post
option.
Soon, I will get the home page back together (I may
have to rebuild it from scratch), then I'll post that, and you can just download
the actual lib with all of the functions and the perldoc in it.

Re: CGI.pm v/s roll-your-own [WAS:] Displaying Problems
The difference is, the efficiency and data structure CGI.pm returns. Mine came to
I think 72
times faster when not uploading images, and 2.5 times faster when uploading images.
I'm not saying
CGI.pm is written poorly or anything, I am saying that it is a little bit bloated and
has a lot of
functionality that is not needed (especially if the only thing you are doing with it
is receiving
input).
Well personally, I've always used
print Content-type:text/html\n\n;
but somebody told me this was not the spec, so I read through the spec and looked up
how CGI.pm was
doing it and what I found was
${CRLF}${CRLF}
as the \n\n replacement. I of coarse should have looked a little higher where they
defined $CRLF,
or at least tested what I had read before posting it, but oh well. From here on out,
I'll stick
with what I've known to work instead.
Like I've said before, it doesn't make much sense to make a wrapper for CGI.pm so
that I can
have things the way I want them, because this is doubling the work necessary. I'm not
making my lib
to prove superior, or to say anything like mine is better. I have simply found a very
positive
solution for me (quick and in a structure that works well for me). If others like my
solution, and
it works well for them too, more power to them. I will post mine on CPAN, if nobody
else in the
world feels it is a good solution for them, that's just fine with me. If people like
my solution,
but have a few suggestions of how to improve it, I welcome that.
One thing I am open to after posting my lib to CPAN is suggestions. I'm not
exactly close
minded here, I'm just the type of person who if I'm not perfectly happy with the way
something works
(whether programming or in the real world), I determine whether I can fix it, if I can
I do.
Because this lib puts the received values in a structure that I like to work with, in
my mind it
fixes things.

Not trying to post hate mail, just reasoning on the subject.
post this at all. What I hope for is several people telling me how to
make it slightly more
efficient or compatible with other OS's (you see I've only had opportunity
to test it on Linux and
Win2000, though I've been testing it on Linux for about 2 1/2 years).
Lincoln Stein (the original author of CGI.pm) already has (lots of) people
doing this for him, and his module has been maintained for around 10 years.
Its been tested on scores of OS's. Ive read four of his books. There is a
book dedicated to CGI.pm. My point is his module has been rigorously
debugged and you are just now here asking people for help debugging yours.
Its pretty hard to make it more simple than:
use Form;
my %input = Form();
But something else has already made it that easy.
Im not knocking your module. Im just explaining why people like us trust
people like Lincoln Stein's module over yours. For example, Ive seen alot of
hand rolled CGI parameter parsers, most of them have a line that says:
@pairs = split(//, $ENV{QUERY_STRING}); # WRONG!!
This works when the user agent uses an as a delimeter, but some user
agents use ; (a semicolon) which is perfectly valid. program chokes. Then
people are in the newsgroups trying to get others to help track down a very,
VERY difficult-to-track bug. But at the end of the post they say, I dont
want to use CGI.pm! Floors me. Really floors me. And this is just one of
several examples I've seen.
So I know, when I say:
print $q-header();
Its going to get it right.
BTW, I find the source to CGI.pm very easy to read and makes alot of sence.
Ive seen suggestions from you in this thread that are either wrong or wont
even work. (What does this do- print Content-type:
text/html${CRLF}${CRLF};) Which tells us again Mr. Stein has a thorough
understanding of the HTTP protocol, while you stll have a little to learn.
Again, this is NOT a flame. I suggest accepting the constructive criticism
professionally.

Re: CGI.pm v/s roll-your-own [WAS:] Displaying Problems
by the way, :) is a smiley, it means I'm joking with you. (reference the last email)
With mine, there is nothing beyond what I described. The hash structure I gave you
below, that's
it. Form.pm takes the input, makes a hash with it, and if you understand how to use a
hash and
array ref, your set. Its just a hash, no objects, no functions, just a hash.
So you use:
use Form.pm
my %input = Form();
and your done. All the data is sitting in the hash %input. You can at that point do
anything you
want to with it.
Like I say, simple and efficient.
If you decide you want to know what you are getting from the cgi input, simply do
something to this
effect:
---
foreach $key(keys(%input)){ # loop through all of the hash elements
if (ref($input{$key}) eq ARRAY){ # if this is an array ref
local $ = ', '; # change the array delimiter to , temporarily for
display
print qq^\@{\$input{$key}} = (@{$input{$key}})\n^;
# print out the array's values
# (make it easy to see which name in the hash this array belongs to)
} else { # if its not an array ref
print qq^\$input{$key} = $input{$key}\n^; # print out the hash element
}
}
---
Anyway, you will be able to get a closer look at it within a months time if you so
choose.

I haven't seen the rest of your module, so I'm not so sure that the point
really stands. It might. But, adding one line to initialize the CGI object
is really not that big a deal considering the kind of power you have
associated with that object. How much extra work do I have to do to utilize
the keys and values in your hash vs. the CGI.pm hash?
The data structure you get back from CGI.pm is:
- Called in a scalar context, a tied hash reference.
- Called in a list context, a standard hash
containing key/value pairs.
- Keys/params with multiple values are returned
as a packed string separated by \0.

I thought my humor was evident enough by the informal language, but I guess I should have put a smiley on it too. I didn't mean hubris in a bad sense. The sense I get from Larry's use of it (from reading the Camel book), and the sense I meant here, was having enough self-confidence to believe that you *can* do all the things you mention, rather than just putting up with what is handed to you because you're too humble to think that little old you could do better. It might tend towards arrogance in some cases, maybe, especially when unwarranted by the actual talent behind it, but true arrogance connotes more negative personality traits, such as not being open to other points of view or debate, and that's *not* what I meant. I did assume familiarity with Larry's philosophy of Laziness, Impatience, and Hubris as The Basis of All Good Software Design, and maybe I shouldn't have. I'd quote some of this from the Camel book, but I don't have it with me. I would summarize it as good programmers don't like write the same thing over and over, yet if they don't like something they got elsewhere, they'll write something themselves that they like better.

Re: Displaying Problems
Kyle,
Well, I'd start by printing an actual content type instead of depending on CGI.pm
for that:
---
print content-type: text/html\n\n;
---
Second, I would condense your if to this
---
my $c = param('c');
my $content = $c;
$content = \n if ($c eq h or $c eq eh or $c eq hd or $c eq p or $c eq c or
$c eq su);
---
Then I would HIGHLY recommend that you not depend on CGI.pm so heavily. I would
suggest you
print out your own html, then you can see exactly what it is displaying and know what
to change. If
you wanted to print it all in one clump, you could do it like this.
---
# the qq^ makes it use ^ as the quote. Just make sure if you us a ^ inside that you
escape it (like
this \^ )
print qq^
html
head
title$thetitle/title
/head
body bgcolor=#FF
!-- the rest of your html goes in here --
/body
/html
^;
---
Trust me on this one, it will save you so much headache if you will just print your
own html.

David

Bob, I fail to see how writing code with errors is somehow CGI.pm's fault No its not.

Me personally, I want to know what's really happening. And once I get to that point, not only can I become more efficient, but I can make better decisions for my own application. You see, just like sterio-typing can frequently be incorrect (because it uses blanket statements), CGI.pm is not the most efficient and for that matter appropriate for many situations. Except that that's not RFC2616-compliant, while CGI.pm's output is So what exactly is the RFC2616 compliant content type? You know its funny, but it seems that so many who stick up for CGI.pm so strongly are quick to say that CGI.pm is doing things right and that it does them better, but they seem to purposely avoid giving the actual solution. It seems to me that our way of life (freedom and prosperity) came about from people thinking for them selves and from innovation, learning and continued drive to improve what was given us.

Re: Displaying Problems
Bob,
That's interesting.
You know, I work with about 5 other perl programmers, most of which do use CGI.pm,
but none of
them use it for anything other that gathering input from the web. I have also
downloaded many
packages from CPAN, I would say a majority of them use CGI.pm, but very rarely do I
see it used for
anything but gathering data.
I'm not suggesting we shouldn't follow the standard. I am suggesting that this
particular
standard will never be enforced, because if it was, I'd be willing to bet, it would
break a great
percentage of perl scripts out there. But yes, I agree with you that we should all
try to follow
the specs pretty closely.
Anyway, personally, I don't use CGI.pm at all, and it would be a real shame if I
began including
the whole thing just for that. It would just seem smarter for me to begin using this
print
Content-type: text/html${CRLF}${CRLF}; instead.
I created a lib for receiving data from GET, POST or shell. I will be releasing
it to CPAN
soon, and expect to get this sort of thing quite a bit. That is good, because I want
my lib to be
very efficient and proper. The reason I wrote my own is because I like my variables
in a easy to
use structure:
%hash = (
'a_name' = 'value', # for single name value pairs
'b_name' = [multiple, values, for, this], # for single name muli-value
sets
'c_name' = {
'original_name' = 'filename.jpg',
'size' = '23554',
'location' =
'/tmp/fileupload/tmpfile-10028983-88.57.192.3-2783-298374-927837'
} # for files
);
With this structure, I can get to everything very easily. It didn't make much
sense to use
CGI.pm to gather the data, smush it into a data structure, only to loop through all
the data and
shove it into another structure.
I'm sure I'll get lots of hate mail from CGI.pm die hard's, but my other choice is
to just not
post this at all. What I hope for is several people telling me how to make it
slightly more
efficient or compatible with other OS's (you see I've only had opportunity to test it
on Linux and
Win2000, though I've been testing it on Linux for about 2 1/2 years).
Its pretty hard to make it more simple than:
use Form;
my %input = Form();

Ok, so here's the deal:
Some HTTP/1.0 software has interpreted a Content-Type header
without charset parameter incorrectly
to mean recipient should guess. Senders wishing to defeat
this behavior MAY include a charset
parameter even when the charset is ISO-8859-1 and SHOULD do
so when it is known that it will not
confuse the recipient.
By the way, I did not upper case the MAY and SHOULD, those
were that way in the doc which means they
were trying to emphasize them. I'd have to say that MAY
doesn't suggest that it is a requirement
for the content-type to work properly.
This is the relevant paragraph from 2.2 that I was going for:
HTTP/1.1 defines the sequence CR LF as the end-of-line marker for all
protocol elements except the entity-body (see appendix 19.3 for
tolerant applications). The end-of-line marker within an entity-body
is defined by its associated media type, as described in section 3.7.
Appendix 19.3 (Tolerant Applications) says, in part:
The line terminator for message-header fields is the sequence CRLF.
However, we recommend that applications, when parsing such headers,
recognize a single LF as a line terminator and ignore the leading CR.
But, section 3.7 says:
When in canonical form, media subtypes of the text type use CRLF as
the text line break. HTTP relaxes this requirement and allows the
transport of text media with plain CR or LF alone representing a line
break when it is done consistently for an entire entity-body. HTTP
applications MUST accept CRLF, bare CR, and bare LF as being
representative of a line break in text media received via HTTP. In
addition, if the text is represented in a character set that does not
use octets 13 and 10 for CR and LF respectively, as is the case for
some multi-byte character sets, HTTP allows the use of whatever octet
sequences are defined by that character set to represent the
equivalent of CR and LF for line breaks. This flexibility regarding
line breaks applies only to text media in the entity-body; a bare CR
or LF MUST NOT be substituted for CRLF within any of the HTTP control
structures (such as header fields and multipart boundaries).
Note especially the last sentence.
A nit-pick, to be sure. But little things like this cause programs
to break all the time. Like I said, most (maybe
Re: calling sub based on database list?
No, this is quite a simple problem actually. Here's how.
my $alias = home|htmlBody,Header,homebody,footer;
my ($name, $subs) = split(/\|/, $alias);
my @subs = split(/\,/, $subs);
foreach $sub(@subs){
my $return_val = {$sub}($pass_in_vars);
}
So the first part I assume you've got where you pull your strings into vars, but
don't put the
on the front of them. Then what you are doing with {$sub}($pass_in_vars); is you are
taking the
string htmlBody or whatever and saying I want to execute a sub called whatever
string is in $sub.
You use the same method as when you are dereferencing say an array ref. For example
my $stuff = [first element, second element, third element];
my @thearray = @{$stuff};
Same technique.

Subject: calling sub based on database list?
Ok, I got sorta a hard questionI think that involves calling randomly changing
subrutines. What
I'm Trying to do is this. 5 libaries are required into my CGI(PERL) program Each of
them has their
own set of subrutines. Now when someone accesses my site they also send a page
referance eg
main.cgi?page=home What im trying to get my code to do is take 'home' and then
start runing
subrutines based on a file entry that can be edited from my admin section of this
site. So basicly
the file looks like this.
home|htmlBody,Header,homebody,footer
So it should get the list of subrutined to call but I can not figure out how to call
them since they
are strings and not hard coded into the code. Basicly I can get the values and print
them out but
not call them. Does anyone have and tips for calling a sub using the name from a
string?
perl.call('htmlBody') does not work as one site pointed out. I guess thats for
something else all
together. Thanx
