Hi, I'm trying to incorporate a "preview" so to speak in my mail form.

A user will fill in their info into a form and click "Next"... then the values read in will be mailed to me. I got that down fine... but instead of taking them to a "thank you" page, I need the script to output their info in html... but I tried it and it leaves out the variables.

if it's not input thru a form, but rather declared in the beginning ($Variable='some predefined value here'), it works all right.... I can't figure out why it won't work if I declare the variable as $Variable=in{'FieldName'};

The method I used was:

print "Content-type: text/html\n\n";
print <<ENDHTML;
<HTML>
<HEAD>
<TITLE>test</TITLE>
</HEAD>
<BODY>
you entered the word: $Variable.
</BODY>
</HTML>

ENDHTML


Someone please help me! Thanks!

It sounds like you arn't parsing the forms before you try to show them,, Try this

-------
Put after your location to perl
-------

read(STDIN, $buffer, $ENV{'CONTENT_LENGTH'});
@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;
$FORM{$name} = $value;

}

##THen declare the forms like so

print "Content-type: text/html\n\n";
print <<ENDHTML;
<HTML>
<HEAD>
<TITLE>test</TITLE>
</HEAD>
<BODY>
you entered the word: $FORM{'usersName'}
</BODY>
</HTML>

ENDHTML

---------------------------
Now the form were the user rights in there data..

<form action="ScriptsName.cgi" method="POST">

<input type="text" name="usersName" value="Your Name">

<input type="submit" value="GO">
</form>


Hope it helps :D

sigh. I tried that. so I thought maybe I made a typo and I pasted exactly what you had but it does exactly what happens without parsing... It just prints the html, and normal text but leaves out the variables. :( so, it prints:

You entered the word:

just like that.

In the form action do you have

method="POST"

would look like this

<form action="script.cgi" method="POST">

I tried your code ans that didn't work... did the same thing as my code:


#!/usr/bin/perl -w

$variable='Name';

print "Content-type: text/html\n\n";
print <<ENDHTML;
<HTML>
<HEAD>
<TITLE>test</TITLE>
</HEAD>
<BODY>
Your name: $variable
</BODY>
</HTML>

ENDHTML
exit;


check this out: http://www.pageresource.com/cgirec/ptut5.htm

that works, but it's declaring the variable's value in the code... but i can't get it to let me read it in from the form instead... I dunno why... your code did the same thing even when parsing the forms

mmm,,, Okay try this,,.

First make the html page as this.

<form action="test.cgi" method="POST">
Your Email Address: <input type="text" name="user" value="">

<input type="submit" value="GO">
</form>

-----------


Now make this script test.cgi

++++++++++

#!/usr/bin/perl

read(STDIN, $buffer, $ENV{'CONTENT_LENGTH'});
@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;
$FORM{$name} = $value;

}

print "Content-type:text/html\n\n";
print "Your Email address is $FORM{'user'}\n";

exit;

sigh. that works. lol. thanx. i just thought i'd be able to use the endhtml deal so that i could avoid escaping some characters like '/' and such... cus i'm going to be using a crapload of tables and it'll be sort of annoying... but oh well. i guess i have no choice! thanks for your help! :thumbsup:

mmmm,, Well before you go through that table thingy hehe,, (nasty:D)

try this instead of print"";

---
print "Content-type:text/html\n\n";
print <<EOF;
Your Email address is $FORM{'user'}
EOF
exit;
