使用Ajax通知所有用户

In my application. I am writing blogs. On submitting a blog, a request is sent to Website Admin for approval.

So i want these request be loaded on Admin's page without reloading.

Now For my ADMIN,

    $(':button').click(function()
{
    var id = $(this).attr('id');

    $.ajax(
    {
        type: 'POST',
        url:'admin_approval.php',
        data: {'id': id},
        success: function(data)
        {
            $(':button[id='+id+'], p[id='+id+'], p[id=date'+id+'], pre[id='+id+']').hide();

        }
    });

});

On approval, a flag in the database is Set from 0 to 1

Owing to this action I want my show_blog.php to get refreshed for all Users

In my show_blog.php, I'm retrieving all blogs from my database..

Any solution to the problem, Can i have repeated Ajax calls every 1 minute ??
