Config::General arrayrefs and HTML::FormFu
I'm in the process of making a nicer backend for charlieharvey.org.uk using Catalyst (which is lovely BTW). One of the things I'm playing with is using HTML::FormFu for making the forms. But this morning I got proper stuck on the simple task of populating a select box with options from my Config::General config file.
I know what you're going to say. How come you're not using YAML. Well, its mostly its weird treatment of tabs and spaces, which I've found annoying enough to make me dislike it. I once spent an hour at New Internationalist trying to debug a YAML config for FormBuilder. I ended up having to reindent one character at a time.
Anyhow the problem was pretty simple to solve in the end, but doesn't seem documented in exactly this context on the web much, at least not for the terms I was googling. If you want an arrayref for a select element in your HTML::FormFu form you need to specify multiple blocks with each block having a label and value for that option. Here's the one I used for my Writings media types.
<elements>
name media
id media
type Select
label Media
size 1
<attributes>
title Enter media type; href is special
</attributes>
<options>
value txt
label txt
</options>
<options>
value href
label href
</options>
<options>
value pdf
label pdf
</options>
<options>
value ogg
label ogg
</options>
<options>
value odt
label odt
</options>
<options>
value sxw
label sxw
</options>
</elements>
Kinda long-winded compared to the much nicer YAML way of doing it. But it works OK.
