Description
I have bumped into a variety of posts with this problem. Seems to be it is a basic requirement that you can pass the destination address from a node in drupal to the webform system, but I can't see how. Passing the email in the URL is not an option, as you are just asking for your form to be abused then by spammers. I would like to pass through a node ID, and then write a small piece of php so that webform can get the email address from this node. I know how to make the php to get the datam, but how can I integrate this with webform?
Unless I have missed something?

I found the validation php box and have got as far as the code below. So i take the value of a hidden field and load the node to get the email address out. I now want to stick this address back into the form data so it can be submitted to that address but I have no idea which part of $form or $form_state to modify as the value appears multiple times. is it possible to change the form in the validation stage?
<?php$nid = $form['submitted']['centre']['#value'];
if ( $nid == '' ) {
form_set_error('centre','No such centre');
} else {
$node = node_load($nid);
if ( is_array($node->field_email) ) {
// where can i change the value of this form field? it exists in $form_state as well as $form and in multiple places!
//$form['submitted']['centre']['#value'] = $node->field_email[0]['email'];
} else {
form_set_error('centre','No valid contact email or no such centre');
}
}
?>
Has anyone else done something similar. I find no documentation on how to do this. The code above is worked out from lots of debug output etc.

I'm getting closer. I can change the value of the form now, but the form still goes to "the id" that was set before
validation code
<?php$nid = $form_state['values']['submitted_tree']['centre'];
if ( $nid == '' ) {
form_set_error('centre','No such centre');
} else {
$mynode = node_load($nid);
if ( ! is_array($mynode->field_email) ) {
form_set_error('centre','No valid contact email or no such centre');
}
}
?>
processing code
<?php// set the field to the actual email address for the centre
$nid = $form_state['values']['submitted_tree']['centre'];
$mynode = node_load($nid);
$form_state['values']['submitted_tree']['centre'] = $mynode->field_email[0]['email'];
?>
any help would be most appreciated

SOLVED!
for the process code i use the following
<?php// get the email for the node
$nid = $form_state['values']['submitted_tree']['centre'];
$mynode = node_load($nid);
// set the destination for the form to the email
$node->webform['email'] = $mynode->field_email[0]['email'];
?>
hopefully others will find this useful too.

exobuzz... absolutely brilliant! Thanks a ton!

This is exactly the logic I need ... still doesn't seem to work for me.
It seems like I can't modify that field : $node->webform['email']
In my case, the mail is deduced this way : node url (HTTP_REFERER) -> node id -> author id -> author email
Actually, my validation block is empty. Could this be the reason ?
Thanks in advance for any advice.
EDIT : well I used a hidden field to catch the node id in $_GET (%get[nid]) instead of using the HTTP_REFERER and it works just fine! Thank you for the trick!

Please exobuzz, could you describe the whole process? I can´t seem to make it work. A lot of people need this so, i think, this should be some standard configuration. Be able to pull the email from anywhere.
OK, please describe: where did you create the hidden field. Whats the name of the hidden field?
Where do you write both codes?
Why am i getting the message "no such centre"?
Thanks

my code is tailor made for my scenario. It will differ depending, so you need to understand the code to modify it. I take a value from a session variable and put it in a hidden field in the form. This is a standard operation. I create the session variable on another drupal page, however you could pass it as a parameter also.
in my case I pass a node id into the form. the node contains an email field that I want the form to go to.
In the validation code, I check that the hidden field (in my case centre) contains something. If it does, I do a node load on it, and then check if there is the email field. If not I give an error. You would want to change the error and field name accordingly
In the Processing code, I get the node id that was previously validated, load the node, and extract the email address. I then set the destination of the form to this address.
You are getting the no such centre error, as you have nothing in a field called "centre" in your form. change this to reflect your field values.
Feel free to petition for some built in functionality like this.

thank you exobuzz, but still stuck.
I have the same needs as you. I need to collect the email from the node based on his id.
I created a hidden field in the form called centre too. But what code do i put in it, and what value? What do i do with this field?
How do i create this session variable. That´s where i´m stuck. I need the code and where do i write it.
In my case every page of a certain content type will have this session variable retrieved to be sent an email to.
In this content type i also have a field called "field_emailestabelecimento". This is where the email is.

you can pass the node id to the webform in a querystring which might be easiest and then get the webform to put this in a hidden field. See "Setting default values from the url" on http://drupal.org/node/296453
