I'm implementing a sortable list of images with jquery in a Zend Framework application. I just can't get the .sortable('serialize') method to return more than an empty string.

When I try with a few simple examples outside my application it works.

Does it matter that the snippet below is wrapped in various other and other tags. I think it shouldn't. The unordered list should be found just by the id, right?


<ul id="mylist">
    <li id="1">
            <img src="image_1.jpg" />
            <p class="value_item">some text</p>
    <li id="2">
            <img src="image_2.jpg" />
            <p class="value_item">some text</p>


$(document).ready(function() {  			   
        update: function() {
            var order = $('#mylist').sortable('serialize');

If serialize returns an empty string, make sure the id attributes include an underscore. They must be in the form: "set_number" For example, a 3 element list with id attributes foo_1, foo_5, foo_2 will serialize to foo[]=1&foo[]=5&foo[]=2. You can use an underscore, equal sign or hyphen to separate the set and number. For example foo=1 or foo-1 or foo_1 all serialize to foo[]=1.
