[jQuery] How to post a parameter with multivalues in ajax that PHP can understand

[pcdinh]

Hi all,

I have had a problem in making a post to my PHP server in ajax manner.
My form has a selection box that an user can select multivalue. It
means that I need to make a post to my server using a parameter that
accept multivalues.

Here is my code:

$("#submit").click(function() {
            $.ajax({
                        type: "POST",
                        url:  "post_json.php",
                        data:  {
                               message: 'help',
                               id: 1,
                               year: $('#year').val(),
                               input: ['45', '34'] // This line is ok with Java 
but will
cause PHP confused
                        },

                        dataType: "json",
                        success: function(json) {

                        },

                        error: function(request) {
                                $("div#content").empty().append("There is a 
problem with your
request: " + request.responseText);
                        }

            });
        });

The problem is the line input: ['45', '34'] will cause JQuery making
an URL input=45&input=34, that is valid in Java but not is the case in
PHP because PHP requires that url must be input[]=45&input[]=34. How
can I do that in Jquery way?

Thanks
