MailForm Module
included (not copied! from original-doc


This module can be used to collect user input via a web form and receive the filled form via email. The email can be sent to any registered Wikidot users.


attribute required allowed values default description
to no user names site admins comma-delimited list of Wikidot user names
button no any string "send" text displayed within the send button
format no "csv" none chooses alternative format of serializing the form data
title no text " - MailForm form data" title of the email containing the submitted form
successPage no valid page name none after the form is sent the browser will be redirected to the specified page. put a "thank you" there if you wish ;-)

The names of the 'to' recipients may not contain spaces: to specify a user name that has spaces, replace each space with a hyphen or underscore. If you do not specify a 'to' argument, the email will be sent to all site admins.

The definition of the form must be enclosed within the [[module … ]] … [[/module]] tags. The full specification of how to do this:

The definition of the fields is a nested list that looks like this:

# field1_name
 * option1_name: value
 * option2_name: value2
  * suboption1_nam: value
# field2_name
 * ...

where field_name is the alphanumeric identifier of the field, e.g. first_name. The options are:

option name required allowed values default description
title no, but recommended! any string field_name title of the field displayed in the same row on the left
type no text, textarea, select, checkbox text type of the input field
size no integer 30 size of the input field
default no value of the input none in case of the "text" or "textarea" fields it is just a string that appears inside the field; in case of "select" it must be one of the option labels
hint no any text none
options only for "select", see below
rules validation rules, see below

"Select" type

If your field is a "select" field, you must also provide options for it. Do so as shown:

# field_name 
 * title: Gender
 * type: select
 * default: male
 * options:
  * male: Male
  * female: Female
  * option_name: Displayed value

where the "default: …" is not required, but if provided it should match one of the names of the options.


This module offers a powerful way to validate the input data. To use validation do:

# field_name
 * title: Validated field
 * type: text
 * rules:
  * rule1_name: value
  * rule2_name: value

where rules are:

rule name allowed values description
required anything, e.g. "true" if the field is required
minLength integer does not allow strings shorter than limit
maxLength integer does not allow strings longer than limit
match perl regular expression checks the value against expression, e.g. /[a-z0-9]+/ allows only lowercase letters and numbers
number anything, e.g. "true" checks if numeric
minValue number for numerical fields sets the lower limit
maxValue number for numerical fields sets the upper limit
