Answer 1

Change this line:

window.location.href = "<?php echo site_url('controller_d/login/admin_link_delete_user?id='.id);?>";

To:

window.location.href = "<?php echo site_url('controller_d/login/admin_link_delete_user');?>?id="+id;

Answer 2

Try using this

window.location.href = "<?php echo site_url('controller_d/login/admin_link_delete_user/'.id);?>";

assuming that in your controller you have this method

function admin_link_delete_user($id){
     echo $id;// u'll get the id which you are passing through javascript    
}

<script type="text/javascript">
function makeajaxcall(id)
{
      //alert(id);
      var r=confirm("Do you want to Delete");
      if (r==true)
      {
           $.post("<?php echo site_url('controller_d/login/admin_link_delete_user/');?>", {id:id},
           function(data) {
                alert(data+"a");
           }, 'json');
      }
      else
      {
           x="You pressed Cancel!";
           alert(x);
      }

}
</script>  

in controller

function admin_link_delete_user(){
   echo $this->input->post('id');
   //perform your code
}
