$('#showdata').on('click', '.item-edit', function(){

            var id = $(this).attr('data');
            $('#update_model').modal('show');
         //s  $('#myform').attr('action', '<?php echo site_url() ?>/Admin/Authorisation/update');

id is going undefined when i try to update something in codeigniter its taking only id 1. Not gething the correct id. when i alert my id its saying undefined. and in place of id its going null so could not update any thing

Answer 1

the problem is you are getting your id in variable named id, but you are passing it as client_id.

     data: {id: client_id},

this should be data: {id: id},
