That's one of the minor features I wrote into my UpdateForm recipe...
you could adapt the code to do the same thing in scripts/forms.php.
Here are the relevant lines from updateform.php:
toward the top of the script:
# (:update textarea:)
':html' => "<textarea \$UpdateFormArgs>\$UpdateTextarea</textarea>"));
toward the bottom of the script:
$FmtV['$UpdateTextarea'] = $UpdateFields[$opt['name']]?
$UpdateFields[$opt['name']]: " ";
So basically you'd just change all places where it says "Update" to
"Input" and add $InputTextarea to your list of global declarations in
the InputMarkup function, and that should do the trick.
Needless to say this is a very useful feature, and I hope to see it
incorporated in a future version of PmWiki. ;-)

This can also be done with UpdateForm, if you don't mind keeping the
lists of values in a database... the syntax for a <select> box becomes,
(:update select field_to_save value=id_field label=label_field
All the <option> rows are generated automatically and the value that's
saved in the record you're currently viewing is automatically selected.
You could set default values for a new record by creating a record in
the table with a key value of 0 (or "" if your key field is not numeric)
-- every time the page is loaded with no key specified, it would get the
default values from the record with the 0 key.
Similarly with radio buttons and checkboxes -- whatever values are saved
in the record you're viewing are automatically checked... but you do
have to code each of the radio buttons individually, which can be a pain
when there are a lot of them. I haven't figured a good way to generate
sets of radio buttons automatically.
If you want to incorporate something similar into your FASTdata recipe,
feel free! But I think the two recipes should get along pretty well in
the same installation. --Ben
