The tag returns the named form input field value. Any Interchange tags in the output are HTML- and ITL-escaped by default for security reasons.
This tag is very similar to [value]
, except that it provides the
default value for the default=
parameter.
Example: displaying user's first name in a modifiable field
<form action="[process]"> Hello, <input type="text" name="fname" value="[default fname Anonymous]" />! </form>
TODO: Add a submit button
Example: displaying user's first name, or falling back to the default
Hello, [default fname Anonymous]!
