But that won't help in this case.
See, there are two different URL's. First, form.html calls the formmail cgi
with the url in the FORM ACTION. Then the user is redirected by formmail
with the URL in the redirect form element.
Additions to the link to the formmail script are of course not seen by the
following php3 page, because that's another link.
Form.html has a textbox with the message and a hidden textbox with redirect
URL.
[form.html]
|
| <form action="http://~/formmail.pl"?
V
[formmail.pl]
|
| redirect
V
[faq_confirm.php3] show message here
Formmail.pl does not need any addition to the link; it gets the form
elements by magic (POST method defined in FORM tag), like php scripts would
too, only with a different name.
To pass the textbox message through as you ask, the message needs to be in
the redirect URL. This addition of the message i can imagine can be done in
the first page with javascript (suggestion D) , in the formmail.pl (B) or in
formmail.php (C).
However, I suggest to change your concept as in suggestion A.
None is tested or claims to be complete. Just giving a direction and hints.
*************************************************************
A. Make your own PHP script
[form.html]
|
| form action="confirm.php3"
V
[faq_confirm.php3] with sendmail and print a HTML with $message
I strongly suggest to abandone formmail.pl, make a php script instead that
specifically sends a mail with the data from the form (use php function
sendmail() ) and then shows the response page with the content of that
specific text box. That's really the easiest way
If you called the message box 'message' the text will be in variable
$message .
A is best because: - all is done in one script,
- you will learn how to do this
- no use of long url and no dangers of too
long text in
that box of yours. (this socalled GET method
(with the ?
and variables in the URL) is limited
in some older browsers and maybe even servers
to
sometimes only 256 characters)
- this is the only proposal where you can do
some validation in php before sending the mail.
Disadvantage to formmail: formmail doesn't care if you rename your own form
element names. Your own php script will probably not catch all form
elements, unless if you check for all element names in PHP_POST_VARS - see
PHP manual function.each.html and language.variables.external.html.
*************************************************************
B. Modify the Perl Script (hard)
[form.html]
|
| form action="formmail.pl"
V
[formmail.pl] adapt redirect here
|
| redirect: .php3?message=bla
V
[faq_confirm.php3]
If you have access to the script and nobody minds you changing it, find this
line in the formmail.pl :
print "Location: $Config{'redirect'}\n\n";
This one calls a page mentioned in your form's textbox named 'redirect'
(see formmail documentation).
Now somehow add the textbox you need. It MIGHT look like this (i forgot
about scope and all kinds of perl details).
print "Location: $Config{'redirect'}".
'?nameofyourtextbox='
"$Config{'nameofyourtextbox'}".
"\n\n";
And hopefully variable $nameofyourtextbox in your redirect page.php contains
the text. MIND YOU i think you have to change the textbox contents to
prevent the spaces in the textbox (space would end the URL and you;ll end up
with only the 1st word), so you will have to find the Perl equivalent of
urlencode like this:
&urlencode($Config{'nameofyourtextbox'}).
Perl is more difficult to debug than PHP and i only give this to help you
going. I will not test it. I have many doubts about the way perl handles
qquotes and whether it is needed to escape the ?-mark. Find Perl gurus to
make it work.
Also check if your textbox even ends up in $config, maybe check the part
just after "# Define the configuration associative array. ".
*************************************************************
C. Adapt formmail.php (easy)
[form.html]
|
| form action="formmail.PHP"
V
[formmail.PHP] adapt redirect here
|
| redirect url?message=bla
V
[faq_confirm.php3]
find formmail.php instead of formmail.pl. I saw it hanging out there
somewhere, someone translated the perl script to a php version. It's free!?
Now it's less difficult. In the script find the forwarding line: it is
probably near the words header("location: $redirect").
Now to add the textbox i think it would be something like this:
$redirect .= '?nameofyourtextbox='.urlencode($nameofyourtextbox)."\n\n";
header("Location: $redirect");
exit;
(in your first form:
<FORM METHOD = 'POST' Name='.....' ACTION='http://path/formmail.php'>
<input type='hidden'
name='redirect'
value='http://www.ahost.org/jstump/faq_confirm.php3'>
<input type='text'
name='nameofyourtextbox'>
</form>
)
For C you can consider to study sessions() and make a session remember the
variable instead of clipping it to the URL, with the disadvantage of the GET
method mentioned in A.
*************************************************************
D Javascript
[form.html] change to redirect?var=message with javascript
|
| form action="formmail.pl"
V
[formmail.pl]
|
| redirect?var=message
V
[faq_confirm.php3]
Make a javascript which executes on submit, which safely adds the textbox to
the redirect. Only works if the javascript works in the users' browser, just
wanted to mention it. Probably a dangerous idea.
_like_ this:
<script language="javascript">
//<--
function addtextbox(){
document.formname.redirect.value = document.formname.redirect.value+
escape (
document.formname.yrtextbox.value)
location.href="http://path/formmail.pl" // or .php
exit;
}
//--> (where escape does what urlencode does in PHP)
</script>
and
<FORM METHOD = 'POST' Name='formname' OnSubmit='addtextbox()'>
<input type='hidden'
name='redirect'
value='http://www.ahost.org/jstump/faq_confirm.php3'>
<input type='text'
name='yrtextbox'>
</form>
*************************************************************
Jees, i surely hope you can use one of these brilliant ideas :-).
