Grid not saving, problem much?

[Remotive]

Hey guys, I am going to get straight to the point, so here it goes...

I am trying to get the drag, drop and save script from TechTuts to work, I tried alot of things to fix this and for some reason it just won't work, I have fixed all I can but I need some help as it asks me if I want to save it and I click OK it says its saved then I reload and the image has gone and there is no entry in the database, meaning there is a saving problem of course.

So, will you guys help me? If yeah here are the codes...

save.js

function ajaxReq()
{
    if (typeof XMLHttpRequest != "undefined") // XMLHttpRequest is supported by the browser...
    {
        return new XMLHttpRequest(); // Use it.
    }
    else if (typeof ActiveXObject != "undefined") // Else if the browser supports ActiveXObjects's, IE.
    {
        return new ActiveXObject("Microsoft.XMLHTTP"); // Use it.
    }
    else // Else nothing is supported...
    {
        throw new Error("XMLHttpRequest not supported"); // Show error
    }
}

var ajax = ajaxReq();
// Assign an ajax request to the global ajax variable
/*********************************/
function saveGridObjects()
{
    var objects = ""; // Create an empty objects string
    
    // Run through the gridObjects array full of all the objects on the grid
    for (i = 0; i < gridObjects.length; i += 1)
    {
        var obj = document.getElementById(gridObjects[i]);
        // Get each element
                
        objects +=
        "[array]" +

Those two files are the ones that save everything.

I have mainly fixed the save.js as I said but if there are anymore errors can people please point them out or even better correct them for me?

Any help is MUCH appreciated. :eusa_clap
