Send Email Plugin

Send e-mails through an e-mail form.

Screenshot

Usage

  1. Create a form on the page that invokes the sendemail script
  2. Add a "to" field and a submit button
  3. Make sure to fill in allowed 'to' addresses in setting {Permissions}{Allow}{MailTo} in configure

Example

Send to:  

<form enctype="application/x-www-form-urlencoded" name="mailform" action="%SCRIPTURL{sendemail}%/%WEB%/%TOPIC%" method="POST">
<input type="hidden" name="subject" value="hello!" />
Send to: <input class="foswikiInputField" name="to" size="30" type="text" value="email address..." />&nbsp;
<input type="submit" class="foswikiSubmit" value="Send" />
</form>

Usage details

Sending emails through a form may contain these elements:
  1. An HTML form
  2. Allow/restrict settings in configure
  3. Optionally a feedback message macro SENDEMAIL
  4. Optionally a custom email template

HTML form elements

The HTML form encapsulates the data to be sent, each part passed as a form field, either an input field or hidden field.
<form enctype="application/x-www-form-urlencoded" name="mailform" action="%SCRIPTURL{sendemail}%/%WEB%/%TOPIC%" method="POST">
... fields ...
<input type="submit" class="foswikiSubmit" value="Send" />
</form>

Note, that the from, to and cc parameters can be either an email address or a wiki user name, in which case the email address of that wiki user is used instead.

Element Required Description Example
name,method Required A form must have a name; send method is POST.  
action Required Must call sendemail script action="%SCRIPTURL{sendemail}%/%WEB%/%TOPIC%"
to field Required Text input field or hidden field <input class="foswikiInputField" name="to" size="30" type="text" />
from field Optional Text input field or hidden field. May be used to specify a different sender, otherwise defaults to the mail address of the current user. <input class="foswikiInputField" name="from" size="30" type="text" />
cc field Optional Text input field or hidden field <input class="foswikiInputField" name="cc" size="30" type="text" />
subject field Optional Text input field or hidden field <input class="foswikiInputField" name="subject" size="30" type="text" />
body field Optional Textarea or hidden field <textarea class="foswikiInputField" cols="70" name="body" rows="6" style="width:100%"></textarea>
mailtemplate field Optional (Presumably) hidden field. See Email template <input type="hidden" name="mailtemplate" value="Main.MailTemplate" />
redirectto field Optional (Presumably) hidden field. If passed, after a sent success or error, the page gets redirected to this url. <input type="hidden" name="redirectto" value="%SCRIPTURL{view}%/%WEB%/MailFeedback" />
successsection field Optional (Presumably) hidden field. Will display a named section (that you define using STARTSECTION and ENDSECTION after a successful sent. <input type="hidden" name="successsection" value="feedbackYes" />
errorsection field Optional (Presumably) hidden field. Will display a named section (that you define using STARTSECTION and ENDSECTION after an unsuccessful sent. <input type="hidden" name="errorsection" value="feedbackNo" />

Allow/restrict settings

To prevent this plugin to be used as open email relay, by default sending emails is prohibited. To send out mails, first set the mail addresses you want to allow to send to in configure. Each can be a list of comma separated regular expressions that emails are checked against before allowing the mail to be sent.
  • {Plugins}{SendEmailPlugin}{Permissions}{Allow}{MailTo} - enter .* to allow to send to anyone
  • {Plugins}{SendEmailPlugin}{Permissions}{Deny}{MailTo}

Other preferences can be set depending on your needs:
  • {Plugins}{SendEmailPlugin}{Permissions}{Allow}{MailFrom}
  • {Plugins}{SendEmailPlugin}{Permissions}{Deny}{MailFrom}
  • {Plugins}{SendEmailPlugin}{Permissions}{Allow}{MailCc}
  • {Plugins}{SendEmailPlugin}{Permissions}{Deny}{MailCc}

Each Deny is evaluated after each Allow, so Deny settings overrule Allow settings.

Examples of allow/restrict settings

  • Allow to send to:
    • Set {SendEmailPlugin}{Permissions}{Allow}{MailTo} to:
      • john@tar.com to only allow to send mails to John
      • john@tar.com|mary@look.ca to allow to send mails to John and Mary
      • .*@tar.com to send mails to any address at @tar.com
      • .*@tar.com,mary@.* to send mails to any address at @tar.com and to all Marys in the world
  • Deny to send to:
    • Set {SendEmailPlugin}{Permissions}{Deny}{MailTo} to:
      • .*@tar.com to deny to any address at @tar.com
      • .* to deny any address (no emails will be sent)

The same rules apply for {MailFrom} and {MailCc}.

Feedback notifications

Use the macro SENDEMAIL to write a feedback message on the page, on the position of the macro.

Simply:
%SENDEMAIL%
will write a feedback message (if any), using the default message strings set in configure.

The message can be tailored using SENDEMAIL parameters:

Parameter Description Example
feedbackSuccess Message string in case of successful send. feedbackSuccess="Request sent, we'll contact you shortly."
feedbackError Message string in case of unsuccessful send. feedbackError="Could not send your message, please contact us."
format A format string. Use $message as placeholder for the actual feedback message. format="<div class=\"foswikiNotification\">$message</div>"

Feedback notification example

%SENDEMAIL{
feedbackSuccess="Request sent, we'll contact you shortly."
feedbackError="Could not send your message, please contact us."
format="<div class=\"foswikiNotification\">$message</div>"
}%

Email template

To customize the email, including its header, create a new template topic and pass the topic name in a mailtemplate form field. The default template is SendEmailPluginTemplate:

From: %FROM%
To: %TO%
CC: %CC%
Subject: %SUBJECT%

%BODY%
The tags %FROM%, %TO%, %CC%, %SUBJECT% and %BODY% are replaced with the respective form values when the email is created.

For a template topic named MailTemplate you can either pass the name Mail or MailTemplate.

The search path for templates always starts in the current web.

FAQ

How do I create linebreaks in the email body?

Use the token $n to create newlines.

How do I send data form fields?

If you have a data form with the fields Title and Summary and want to post the values of these fields in the body of the e-mail, eiter:
  • put them in a hidden field:
    <input type="hidden" name="body" value="Title: %FORMFIELD{"Title"}%, Summary: %FORMFIELD{"Summary"}%" />
    
  • preserve linebreaks by putting them in a textarea:
    <textarea name="body" class="foswikiHidden" cols="80" rows="6">
    Title: %FORMFIELD{"Title"}%
    Summary: %FORMFIELD{"Summary"}%
    </textarea>
