UBB.Developers Forums Community Development Programming PHP and Server-side Scripting Anyone good with CGI or Perl?

I need to know how to find something in a CGI/Perl document and replace it with something else. It's for an interactive story I have, I want people to be able to make a return and have it go down to the next line... so, basically, how do I find n and replace it with < br > ? BUT... here's the tricky part...

The CGI file is a totally different file than where the story shows up. The Add Paragraph form in Story.shtml (the file where the story shows up) goes to story.cgi and tells it to add this paragraph, and then it sends it back and adds it. So, how would I find n in the form where people type their paragraph in story.shtml and replace it with < br >, from story.cgi?

Thanks!

CGI is a protocal.

Perl is the scripting language.

Please use Perl when refering to a Perl script that functions as a CGI.

Moving this to the Perl forum.

Right before you send it back, add:

$variable =~ s/n/
/ig;

(change $variable to the variable's name)

Eep, sorry about posting in the wrong forum.

And, which variable should I replace it with, and where exactly should I put that?

the $variable should be whatever variable the line of text you are getting from the user is. And should come after you get that line of text from the user.

Hmmm... This is what I have:

Is that how/where it should be? (look three lines from the bottom, that's the code you gave me)

er.... sorry for stretching the whole page

If anyone wants me to, I can send them the whole cgi file so they can look at it for me and tell me what to put?

uh, i would do something more like this...

as far as what you doing, it looks like your adding the code in, then replacing the n with
but you should replace first, then add.

ok, now I have:

I got a 500 internal server error.

how are you getting this info from the form? Are you useing the use::CGI modedule or that long ugly code that does sorta the same thing?

oh and BTW, it seems like to me, you are formating all the stuff then putting it into the story.cgi file, so, pray tell, why are you putting it into a cgi file? why not just put it into a TXT file and call it via SSI? That seems to me to be the easiest way...

What?
If you want to take a look at what the CGI script is doing, go here: http://www.thegrabbag.net/story.shtml
Let me try to restate the question...
The CGI script is telling the form what to do. The CGI script writes what the person typed to story.shtml, and I'm wondering how to make it so that whenever the person makes a Return, I want to replace it with an HTML break,
, because when the script writes the text to story.shtml, it just writes it with the returns, and only pre-formatted text will recognize returns as breaks. So I want to replace all returns with
, so that they show up as breaks.

It's the same thing with UBB, when you hit the Enter key on your keyboard, the UBB script replaces that with a
tag.

How do I do that?

no good
Is there a way to find n in a certain form (in this case, "story"), and then replace the stuff? Except, the form is in story.shtml.

Okay, i don't know what to tell you then, that is the exact line of code to replace the n you just have to put it in the right place.

ok, thanks anyways.

Change:


$FORM{'story'} is the variable that contains the story the user wrote, thus you want that variable to be pattern matched as indicated above to transform linebreaks into HTML breaks.
