how to convert data from javscript to a php variable

[onairric]

Hi guys, need help again.

I have a ajax-powered "Arrange Content by Drag-and-drop" php page here -> http://network.rxpinoy.com/temp-tester.php

I found the script here -> http://www.dhtmlgoodies.com/index.html?showDownload=true&whichScript=arrange-nodes-2

The page works but I have to be able to save the changes to a database.

Currently, when we click the save button at the end of the page, a dialog box will appear that will display a string of ID numbers (of the items being arranged) sorted according to their order in the page, separated by a semi-colon.

I want to be able to save the string on the database and the use php explode to echo them correctly.

Below is the javascript that puts the ID numbers into a string:

<script type="text/javascript">
/* The saveData function creates a string containing the ids of your dragable elements. 

The format of this string is as follow

id of item 1;id of item 2;id of item 3

i.e. a semi colon separated list. The id is something you put in as "id" attribute of your dragable elements.

*/

function saveData()
{
	var saveString = "";
	for(var no=0;no<dragableObjectArray.length;no++){
		if(saveString.length>0)saveString = saveString + ';';
		ref = dragableObjectArray[no];
		saveString = saveString + ref['obj'].id;
	}	

	alert(saveString);	// Create pop-up dialog box - For demo only
}
</script>

as you can see, the "saveString" is the string that contains the IDs. I just need to convert the "saveString" to a php variable ($savestring) so I can save it to the database and use Php explode to display the items correctly.

Please help. Thanks!
