sending json data to server

Question

I have this code to send data:

function insert_new_image()
{
    var ids = [];
    $('.be-imagecontainer').each(function(i){
        ids[i] =$(this).find('span').text();
    });

    var jsonids = {'ids' : ids}

    var url  = base_url + 'ajax/get_new_images';
    $.ajax({
        url : url,
        data : {'ids' : jsonids},
        success : function(response)
        {
            $('#be-images ul').prepend(response)
        },
        dataType: 'html'
    });
}

and this code from the server(PHP):

function get_new_images()
    {
        $ids = json_decode($_GET['ids'], true);

        echo Kohana::debug($ids);
    }

the server responds with a

null

how can I make this work? I am trying to send a json data containing an array of ids to the server

Answer 1

Use json2.js to encode the Javascript object as JSON:

 data: {ids: JSON.stringify(jsonids)};

See this post for more information.

Answer 2

The data you send back isn't in JSON format, it should be a PHP array by the time your script reads it.

Either use : var jsonids = "{'ids' : ids}" (in JS) or $ids = $_GET['ids']; (in PHP)

Answer 3

Have you var_dump the $_GET variable? Maybe you aren't sending the right thing. Also check php.log

Another question, Kohana what kind of thing is responding?
