如何使用jQuery发布数据

Question

I'm using PHP to submit a very simple data to db. On my page.php, I have a link, by clicking it I insert its id and some other data in the database. For example:

echo "<a href='".$base_url."?submit=$page_id'> Submit it</a>";

It generates the url like page/test-page/?submit=12

On the top of the page I get the page id with $_GET and insert it to the db in the following way:

if (isset($_GET["submit"])) {
        $page_id = $_GET['submit'] //yes, its not secure.       
        //insert in db.     
        //get db success/error msg in $db_msg       
    }

How can I submit the data and get the database success or fail message without refreshing the page.

check out the JQuery Documentation about Ajax Functions: http://api.jquery.com/jQuery.post/

you'd do something like

 $.ajax({
  type: 'POST',
  url: page.php,
  data: submit=$page_id,
  success: function(){print("success");}
});

btw: it is better to use post than get, it just looks cleaner. (at least in my opinion)
