Get Mysql insert_id in java

ok all just to let you know i found a solution

i added these two lines to my controller function

Code:

$this->output->set_content_type('application/json');
    $this->output->set_output(json_encode($data))

and changed my java like so

Code:

$('#statusupdate').click(function(){  // when user click no move to next profile and save choice to db
var val_post = $("#msgstatus").val();
              
  
                 $.get("http://www.leap-it.be/tangoo2/auth_public/set_post/"+ val_post,
     function(data){
                
       alert(data.postid);
            });

if my coding looks bad let me know

thx
