Template:Form

Template documentation

This template is a template gadget. It requires the WikiForm gadget to work, which is loaded automatically when this template is used.

Use this template to create forms that can create new pages or add content to existing pages.

Parameters

General

The following parameters control the general behavior of the form:

template — Required! Name of the template that will process and format the submitted data. If you don't want to use a template (or if you want to use several templates) then you can create a template meant to be substituted and set subst:Your template as the value of this parameter.
page — Name of the page where the data will be posted. If the page doesn't exist, it will be created. If the page exists, the data will be appended. If omitted, the current page will be used. If the given page name contains a string like "{{{x}}}", it will be replaced with the value of the field named "x". This allows to build page names dynamically by combining predefined text and field values.
section — Name of the section where the data will be posted. If the section doesn't exist, it will be created. If the section exists, the data will be appended. If omitted, the data will be appended to the page. If the given section name contains a string like "{{{x}}}", it will be replaced with the value of the field named "x". This allows to build section names dynamically by combining predefined text and field values.
redirect — Set this to any value to redirect the user to the page (and section) where the data was posted. If omitted, then a success message defined by submit-success (see below) will be shown instead.
group — User group that is allowed to fill out the form, for example 'user' or 'sysop'. If omitted, then all user groups are allowed.

Fields

The following parameters control the form fields:

fieldN (replacing N for a number from 0 to 99) — Name of the field. This will also be the name of the parameter fed to the template. If you want to use anonymous parameters, just name them using numbers (e.g. field1 = 1). If no fields are defined, then the template will be injected with no parameters.
fieldN-label — Label of the field.
fieldN-help — Help text of the field.
fieldN-value — Default value of the field.
fieldN-placeholder — Placeholder of the field.
fieldN-required — Whether the field is required. Any value means yes.
fieldN-disabled — Whether to disable the field. Any value means yes.
fieldN-type — Type of the field. Supported values are:
- text — Use it for plain text inputs. This is the default field type. Use fieldN-values, fieldN-values-from-search to suggest values.
- textarea — Use it for multi-line text inputs.
- number — Use it for number inputs. Use fieldN-min and fieldN-max to limit the allowed numbers.
- checkbox — Use it for multi-checkbox inputs. Use fieldN-values to set the checkboxes. If you only need a single checkbox, consider using boolean instead.
- dropdown — Use it for dropdown menus. Use fieldN-values to set the allowed values. If fieldN-required is not set, then an additional empty option will be included, using fieldN-placeholder as the label.
- radio — Use it for radio select inputs. Use fieldN-values to set the allowed values. If fieldN-required is not set, then an additional empty option will be included, using fieldN-placeholder as the label.
- boolean — Use it for boolean inputs. Boolean inputs render as a single checkbox. If the checkbox is checked, then the value of fieldN-value will be posted, or "1" if no value is set. If the checkbox is not checked, then no value will be posted. Use fieldN-selected to control the initial state of the checkbox.
- hidden — Use it for hidden inputs.
fieldN-values — Comma-separated list of values. Relevant for fields of type "text", "checkbox", "dropdown" and "radio".
fieldN-values-from-search — Search query from which to suggest values. Use %s to represent the value typed by the user and see Help:CirrusSearch for other search options. For example, "incategory:Water" will suggest values in the Category:Water, while "%s incategory:Water" will search the category based on the user input.
fieldN-min — Minimum value for "number" fields.
fieldN-max — Maximum value for "number" fields.
fieldN-selected — Initial state for "boolean" fields.

submit — Text of the submit button. Default is "Submit".
