如何使用jQuery发布数据

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)

<a href="#" onclick="$.post(
    '<?php echo $base_url ?>',
    { submit= '<?php echo $page_id ?>'},
    callback_function(data)
)">Submit it</a>

Send a post request to php, and deal with the message ( "data" ) with javascript?

Youll need to use a ajax method as per CyrillC's answer. here is the official docs ajax jquery

(there is a shortcode for using the POST method)

$.post.({ etc

the post method hides your data from the browser (get puts it in the query string) so its cleaner but also better for security

You will need to use AJAX with jQuery. For starters, have a look at the functions load , get and post here . The methods get and post are the ones used to submit the data to server-side scripting , since you are using GET method in PHP , use GET of AJAX
