Question

This is my code:

$(".img-line").sortable({
   update:function(){
      var order = $('.img-line').sortable('serialize');
      $.ajax({
         type: 'POST',
         data: order,
         url: '/ajax/imageSort.php'
      });
      return false;
   }
});

And in my imageSort.php when I try to get the data, looking for it in $_GET or $_POST, they are all empty. How do I get the data the sortable() sends?

You LI should have id.
The the jqueryui documentation. It is explain

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.
