UBB.Developers Forums Community Development Programming PHP and Server-side Scripting Guestbook Help

Hi, since I read a lot about Perl right now, I thoight, giive it a try.. After not too long work,
I kinda made it to the end of this guestbook.. It must show a template, but instead it gives a nasty error:

Please help me ! Thanks (y)

Seems like someone was a little bit tired when he wrote the wordlets_template.

Actually, it's far better to move the HTML into a seperate file entirely. Preferably use something like HTML::Template.

Personal pet peeve of mind. I can't stand having HTML mixed in with my code. Seperation of logic and display goooooood

True, just didn't want to make it too complicated.

Mark, how do I get the HTML::Template file using as a module? Do I need to use package, or import($module). Please help me, I'm going to change the error fixes now.. Oh yea, I Guess I was a bit tired, scipting at 22.30 until, le's say 12.00 with a few beers

It still gives the nasty error.. I know there ae some bugs and the script is not perfectionized, but ithas to be in the subs.. I only call a template and some default arguments.. help please?

Alright, I had a better look at the code, and I must say it's rather confusing, sorry. :rolleyes:

Anyway, I have no idea why you're trying to use read(), when open is probably what you really want to do.
The read function was designed to be the equivalent of the UNIX fread command,
which enables you to read arbitrary number of bytes into a scalar variable.
The syntax is something like: read (filevar, result, length, skipval);
Where "skipval" is optional.
Not going into any more details on that function here.

I got rid of the errors for you,
you can see the file by clicking this link .
Hope that helps a little bit.

Edit: HTML::Template

Thanks Idle, the Gueestbook does popups with no kinds of errors, but I am not able to post a message. check out:

http://gotanscgi.netfirms.com/gb_code.txt
for the script code.. I made 2 files now,
and check out http://gotanscgi.netfirms.com/guestbook_edited.cgi
for the guestbook..
I am getting nothing when I am trying to post a message! Help me please! This is my first scripts, and I want my Perl to be very good, even if I tried to learning it just over a month ago

Re: HTML::Template

I used this for a script I wrote, and later regretted it.

1) There was a report that HTML::Template has memory leaks. This might not be a big problem for a CGI script, but could be serious if you're using mod_perl. I've have some more info on this if you're interested, although not enough information to fix the problem. But that was several months ago. Maybe the problem has been fixed.

2) Doing complex stuff like dynamic nested tables was tricky. As I recall, a two-level nested table requires setting up an array of hashes of arrays of hashes.

I agree that separating the HTML from the "guts" of the script is good methodology. I'm just not sure that HTML::Template is the best approach.

Maybe I should use a package for the HTML Template instead using the module? Also, Dave, do you have seen a little rror, because the guestbook works properly, only it doesn't write the data to the file. Please help

ALso, thanks for the replies guys

I don't recall having any actual problems with HTML::Template myself.

The guy who reported the memory leak (which might be due a bug in Perl, rather than HTML::Template) wrote another template solution, Text::FastTemplate.

Thanks Dave_L for this info. I think I will use this module in the near future, but later on, when I am a bit more experienced with it. Tomorrow I'm getting a huge Perl book, so that may come to any help. I am going to script now (Profile script).. bye

I've never run across any bugs with HTML::Template and I use it all the time. Could have just been something funky on the server.

I haven't used it much in conjuntion with mod_perl, but it's supposed to work well with it. Could have been an older version of the module too..

My book explains the use of HTML::Template and how to use HTML::Template, in the near future, I think I will use this. However, for this simple Guestbook not, it us supposed to be very simple and all the extra files are not needed. I'm not sure to be using print($myhtml) (and concentate $myhtml each time, or printing << blocks.. I think << blocks, but i'm not sure if the printing takes longer or so
