I am trying to save HTML5 drap and drop divs to a database, there current state. this shows what I am trying to save
As you can see from the image, on the left hand side of the page is data that will be dragged into the grid which is what I am trying to save.
Currently I am able to drag the items from the left to the centre of the page in specific locations however I don't know how to then save this data in the state it is in, I am using HTMl5 and have wrote a php page that connects to the database,
I have done research online and found that I may need jQuery which I don't have an understanding of.
In the image you can see I have dragged the data to a specific location on the page.
Below is the html5 source code. Could somebody please help?

</html>below is the code to connect to the database.
<?php
$connection=m ysql_connect( "mi-linux.wlv.ac.uk", "user", "password");
if (!$connection) die( "Cannot connect to DataBase");
// making a connection to the database mysql_select_db("db1500052", $connection) or die( "Can not find DB");
?>
i have now managed to write a update.php page which will send the new position to the database, however still have not got around the jQuery and Ajax side of the html,
<?php
include("config.php");
$array = $_POST['listnumber'];
if ($POST['update'] == "order") {
$x = 1;
foreach ($array as $key => $value) {
$query = "UPDATE dragdrop SET listnumber = ". $x . "WHERE id = " . $value;
mysql_query($query) or die(mysql_error());
$x ++;
}
echo 'Saved';
} ?>
</div>
