This page explains how you can embed input forms into wiki pages.
Input forms don't actually handle processing of the form data -- the feature simply allows creation of forms inside wiki pages. Forms processing can be found in the Cookbook (see below).
Two directives are used to begin and end forms:
(:input form "url" method:) ... (:input end:)
(:input form:) directive starts a form that will post to url using the supplied method. The url must be in quotes. If the url is omitted, then the current page is assumed. If method is omitted then "POST" is assumed. The
(:input end:) directive ends the current form.
Note that this feature doesn't ensure that the form output is correct HTML -- it assumes the author knows a little bit of what he or she is doing. Notably, (:input form:) and (:input end:) shouldn't appear inside tables, and all form fields and controls should be inside an (:input form:)...(:input end:) block.
Standard input controls
The standard input controls are:
(:input text name value size=n:) (:input hidden name value:) (:input password name value:) (:input radio name value:) (:input checkbox name value:) (:input select name value label:) (:input default default-name default-value:) (:input submit name value:) (:input textarea name value rows=n cols=n:) (:input reset name label:) (:input file name label:) (:input image name "src" alt:)
Where name and value are in the HTML syntax: name="addr" value="808 W Franklin".
For most controls the markup has the form:
(:input type name value parameter=value:)
where type is the type of input element (described below), name is the name of the control, value is its initial value, and parameters are used to specify additional attributes to the control. For example, the following creates a text input control with a size of 30 characters:
(:input text authorid "Jane Doe" size=30:)
For convenience, an author can also specify name and value arguments directly using
value= attributes (same as HTML):
(:input text name=authorid value="Jane Doe" size=30:)
textarea control a value can be set from PmWiki 2.2.0beta45 onwards.
submit control will more often be written as:
(:input submit value=label:)
Here's a more complete example, e.g., for a login prompt:
(:input form "http://www.example.com":) (:input hidden action login:) || Name:||(:input text username:) || || Password:||(:input password password:)|| || ||(:input submit value="Log In":) || (:input end:)
(:input select ... :)
The basic form of a select box is a sequence of options:
(:input form:) (:input select name=abc value=1 label=alpha :) (:input select name=abc value=2 label=beta :) (:input select name=abc value=3 label=gamma :) (:input submit:) (:input end:)
The values can be specified positionally:
(:input select abc 1 alpha :)
We can specify the size of the selection box:
(:input select abc 1 alpha size=3 :)
You can specify a multiple select box:
(:input select abc 1 alpha size=3 multiple:)
To have an element selected, use
(:input select abc 2 beta selected=selected:)
Note that to have two select boxes inline, not only should you give them different
name= parameters, but also place a separator, like a character,
or even the null sequence
[==] between them:
(:input form:) (:input select name=FIRST value=1:)(:input select name=FIRST value=2:)[==] (:input select name=SECOND value=3:)(:input select name=SECOND value=4:) (:input end:)
