使用X-Editable-后端部分

So I'm just trying to use xeditable (http://vitalets.github.io/x-editable/docs.html#gettingstarted) to make changes to my database via AJAX. Since I'm new to this concept and I'm (forcefully) working with PHP for the first time, I need some help.

I setup the frontend part, and a script called (say) script.php is handling the data for me (I need to write the new value in my database).

I can't really understand what to do in the script. Can someone guide me towards it? The docs above don't really do it for me.

Looking in a project I worked on a few months back (sorry about the mysql_ stuff – not my choice!)

Something like:

<?
include your/database/connection_stuff.php;


// Can't remember if x-editable passes the table in as well or not
$table = mysql_real_escape_string($_GET['table']);
// If not, 
$table = 'name_of_table';


$value = mysql_real_escape_string($_POST['value']);
$name = mysql_real_escape_string($_POST['name']);
$pk = mysql_real_escape_string($_POST['pk']);

$result = mysql_query("UPDATE `$table` SET `$name` = '$value' WHERE id = '$pk'");

?>

Will do the trick.
