Question

Form sending AJAX code:

var str = $("form").serialize();
alert(str);
// var uns=@unserialize(str);
//alert(uns);
$.ajax({
    type: "POST",
    url: "update.php",
    data: "box1="+str,
    success: function(value)
    {
        $("#data").html(value);  
    }

HTML Form:

<form>
  <input type=checkbox name=box[] value='1'/><input type=checkbox name=box[] value='2'/>
</form>  

In my PHP:

$box=$_POST['box1'];    

How can I access each of the box variable values in PHP side?

Answer 1

Your js should be like this:

var str = $("form").serializeArray();
$.ajax({  
    type: "POST",  
    url: "update.php",  
    data: str,  
    success: function(value) {  
            $("#data").html(value);
    }
});

With php you should loop your result array.

$box = $_POST['box'];
foreach ($box as $x) {
    echo $x;
}

Edit:
You have to use serializeArray function in jQuery. Then it will work with this code.
