Question

Well, my problems is a little wierd,

I have an AJAX Request to get just a number.

That number is printed on: getMoney.php.
On index.php i have the AJAX request.

Ajax Code:

function getMoney(selected)
        {
            if(selected.value != -1)
            {
                // Obtener presupuesto via AJAX
                $(document).ready(function(){
                    $.ajax({
                            url: "getMoney.php",
                            async: true,
                            success: function(datos){
                                //My action
                            }
                    });
                });
            }
        }

The function is called when I change a value on a Combobox HTML

<select name="area_id" onchange="getMoney(this);">

Well… My problem:
If i write down the numbers on getMoney.php (mannualy) its works perfectly, the AJAX’s get it and the action is done, but when i get the numbers from my database i just get 0. I open mannualy too the getMoney.php, and the numbers ARE THERE! even if i get it from the Database.

What’s wrong?

Answer 1

make sure that getMoney.php is NOT using your standard view headers, i.e. script includes, stylesheet includes or anything else. Also, it’s better practice to have getMoney.php to return a JSON string with your data parametized that way you can pull back diagnosic and error codes as well as specific data. this will help in debugging. look at $.getJSON() if you need help with that.
