每次调用AJAX都会向PHP数组添加$ _POST值

Question

var itemtotal = parseFloat(words[1]).toFixed(2.0)*qty;

            $.ajax({

            type: 'POST',
            url: 'cartitem.php',
            data: {itemtotal:itemtotal},
            success: function(data){

                alert(data);

            }

我想将每个AJAX调用的值添加到PHP数组中以供稍后处理。我怎么能这样做？

Answer 1

php：

if (isset($_POST['itemtotal'])) 
{

$array = [];

if (is_numeric($_POST['itemtotal'])) { 
//you need to do some validation here its just an example
 array_push($array, $_POST['itemtotal']);
}
}

希望有所帮助
