Question

I have code like this:

 $(".delete").click(function() {    
    var commentContainer = $(this).parent();
    var id = $(this).attr("id");            
    var string = 'id='+ id ;
    $.ajax({   
        url: "<?php echo site_url('admin/delete_admin') ?>",
        type: "POST",
        data: string,
        cache: false,
           error: function(){
            $(this).parent().append('You can not delete admin. Please contact main admin .');
        },
        success: function(){
            commentContainer.slideUp('slow', function() {$(this).remove();});               
        }         
    });
    return false;
});

and PHP:

function delete_admin()
{        
    $q = $this->admin_model->get_admin();
    if($q->privilege == 'main_admin')
        {
      $this->admin_model->delete_admin( $_POST['id']);         
        } 
        else 
        {
            return false;
        }
}//end of delete_admin

How to send message that user can’t do delete? Function is working like it is success every time (container is sliding).

Answer 1

The response data is sent to the success callback function, so you can pick it up and check the value.

If you return the string “ok” for success:

success: function(data) {
  if (data == "ok") {
    commentContainer.slideUp('slow', function() {$(this).remove();});               
  } else {
    $(this).parent().append('You can not delete admin. Please contact main admin.');
  }
}
