Jquery sortable list won't serialize, why?

Question

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 s

Answer 1

Jquery runs into problems when you use non-compliant ids.

Ids are not allowed to begin with a number. They can have numbers in them, just not as the first character.

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.
