I am using the awesome drag and drop script found at http://script.aculo.us/. Its a hog, but has lots of features. I have also added a modification that interacts to a db for reordering upon release of a dragable item. Within each dragable is a input checkbox. This checkbox holds a DB id value that is sent on submit. This process works fine in IE, but in FF the checkbox values dont get sent via GET, or POST. How do i get FF to react as i think it should, as IE does.

Just to clarify, If a row is dragged, that row's checkbox will not be sent in the POST vars. It reacts as if not checked. I need all checked boxes to POST. I have has some help on this here, http://www.webdeveloper.com/forum/sh...951#post745951.
I think the quy has a good idea of the direction but its not correct.

Heres a little bit of code from the project beyond the standard script.aculo.us library. Thanks,

Interface Script

Code:

<?php /*   needed for IE   */ ?>
<div id="page">
    <div id="sale_row" class="section">
        <div id="item_1" class="lineitem" style="cursor: move;">example 1 <input type="checkbox" name="check_value[]" value="example1"></div>
        <div id="item_2" class="lineitem" style="cursor: move;">example 2 <input type="checkbox" name="check_value[]" value="example2"></div>
    </div>
</div>

<?php /*   set JS outside *page* div   */ ?>
<script type="text/javascript">
    // <![CDATA[
    sections = ['sale_row'];

    <?php /*   this watches for event changes like drag and drop action   */ ?>
    Event.observe(window,'load',init,false);
    function init() {

        <?php /*   add a sortable.create for each group level div   */ ?>
        Sortable.create('sale_row',{tag:'div', dropOnEmpty:true, containment:sections, only:'lineitem', onUpdate:updateData});
    }

    Sortable.create('page',{tag:'div',only:'section',handle:'handle'});
    // ]]>
</script>

*Javasript* that formats and sends url to ajax db update page. When chekbox vars "params" are sent this works perfectly.

Code:

function updateData() {
    var params = '';
    var sections = document.getElementsByClassName('section');
    sections.each(function(section) {
        params = Sortable.serialize(section.id);
        var ajax = new Ajax.Request(page_url,{
            method: 'post',
            parameters: params
        });
    });
}
