[Catalyst] receiving form-elements in sequence...?

[will trillich]

$c->req->body was empty every time we looked at it, so we went with Hernan's
javascript approach... works a treat! Thanks, folks.

<script type=3D"text/javascript">
// Drag-and-drop might reorder things here,
// so we store the ID sequence in hidden "seq" field, then submit:
function do_submit() {
    var x =3D [];
    $("#services .ix").each( function(){
        x.push( $(this).val() );
    });
    x =3D x.join(',');
    $("#services #seq").val( x );
    $("#services").submit();
}
</script>

<form id=3D"services" method=3D"POST">
<input type=3D"*hidden*" id=3D"*seq*" name=3D"*seq*" value=3D""/>
<ul id=3D"sortable">
[% FOREACH row =3D item_rs.all %]
<li>
    <span class=3D"name">
        [% row.name %]
    </span>
    <span style=3D"email">
        <input type=3D"checkbox" name=3D"email.[% row.id %]" value=3D"Email=
"[%
            row.email_trigger ? ' checked=3D"yes"' : ''
            %]/>
    </span>
    <input type=3D"*hidden*" class=3D"*ix*" value=3D"[% row.id %]" />
    <br clear=3D"both"/>
</li>
[% END %]
</ul>
<button type=3D"button" onClick=3D"*do_submit()*">Save Updates</button>
</form>

We're using http://jqueryui.com/demos/sortable to do the drag-and-drop.
