This sort of thing comes up a lot so I've added a new callback
function called 'beforeSerialize'. You can use it like this:
var ajaxFormOptions = {
beforeSerialize: function($form, opts) {
$("#hidden_input").attr("value","test");
}
};
$('#form').ajaxForm(ajaxFormOptions);
The updated plugin is available here:
