Need help for perl+wml

Hi
I am pretty new 2 perl and also wml, and I desperately need a tutorial for embedding wml in perl or vice versa. I went through the entire forum. There were hardly any queries regarding this topic. There was an example given my jabba in this thread : (URL address blocked: See forum rules)=perl
But the problem is, it is working for simple wml pages like hello world and simple text, but not working for other complex pages(like input boxes, images, etc).

I will be grateful ,if any one can help me finding a decent tutorial as soon as possible(its a little urgent) or can help me by providing some examples.

Hi Ravi, welcome to dev shed.

It is a little diificult to tell which thread you were refering to due to the spam deterent in place for new members.

I don't have any link to perl tutorials, but the basics of writting a WML page in Perl
is the same as writting a HTML page in Perl.

Do you have any code snippets of your work already?
I am sure someone will help you if you post what you have.

You can also go to the Perl forum:
click on "search this forum" and enter WML - a few potentially useful threads come up.

Thanks jabba for your prompt reply. I was referring to this thread:
xttp://forums.devshed.com/wap-programming-20/wml-perl-mysql-226333.html?&highlight=perl
(to avoid spam detection i have replaced h with x...hope it works). Aneways it was written 2 years back, so I think you may no longer remember it.
This was d code in the link you had given:

xml Code:

Original - xml Code
#!/usr/local/bin/perl5.001 push (@INC, "../apputils"); require 'DeckUtils.pl'; #$AppUtils::CGIStandard; $DECK = "<wml> <card> <p> Hello, Unwired World! </p> </card> </wml>"; #Output the deck &AppUtils::OutputDeck($DECK)

#!/usr/local/bin/perl5.001
 
push (@INC, "../apputils");
require 'DeckUtils.pl';
 
#$AppUtils::CGIStandard;
 
$DECK =
"<wml>
<card>
<p>
Hello, Unwired World!
</p>
</card>
</wml>";
 
#Output the deck
&AppUtils::OutputDeck($DECK)

or explicitly passing the http headers...

Its working perfectly for simple text wml files, but not for any thing else. I tried wbmp images, input boxes ,etc, but its workin for none. And the browser I am using(Openwave) is not giving any details. So, if you know of any other methods or a better browser, please inform me. I will be very much greatful to you.

And about searching in d perl forum. I had done that before posting here. I found very few threads for wml, but none were much useful as the perl scripts used were very complex and as I had mentioned I am pretty new to it.

Waiting for your reply....

Can you test this in a web browser that supports WAP (Firefox or Opera)?
(what is the actual output code that you are generating).

It is difficult to guide you when I don't know what DeckUtils.pl does?
It may just be a parsing error?
WML is very unforgiving when the syntax is incorrect?

Instead of using those apputils and deckutils...i explicitly passed d headers using:

Code:

printf('Content-type: text/vnd.wap.wml');
printf("\n");
printf("\n");
printf('<?xml version="1.1"?>');
printf("\n");
printf('<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD wml 1.1//EN"');
printf('"(URL address blocked: See forum rules)">');
printf("\n");
printf($DECK);

this was mentioned in d link provided by you...and as i said its workin fine for hello world and other text, but not for other complex wml files...

What does $DECK generate when you are using images/ inputs etc....
Is it valid WML?
