Answer 1

You send 'url: "admin_operation.php?mode=delete_category&id="+id,' in javascript.
And, in php script you have a condition that rewrite headers and exit script.
if($mode!='add_category' || $_GET['mode']!= "**delete_category**")
{
header('location:dashboard.php');
die;
}
The next block of code
if($mode=='delete_category')
{
// ...
}
never is reached.
Hope this helps you as solution.
