我想以json格式将一些数据发送到PHP并在PHP中进行一些操作。我的问题是我无法通过ajax将json数据发送到我的PHP文件。请帮助我，我该怎么做。我试过这种方式..
<script>
$(function (){
$("#add-cart").click(function(){
var bid=$('#bid').val();
var myqty=new Array()
var myprice=new Array()
qty1=$('#qty10').val();
qty2=$('#qty11').val();
qty3=$('#qty12').val();
price1=$('#price1').val();
price2=$('#price2').val();
price3=$('#price3').val();
var postData =
{
"bid":bid,"location1":"1","quantity1":qty1,"price1":price1,"location2":"2","quantity2":qty2,"price2":price2,"location3":"3","quantity3":qty3,"price3":price3
}
var dataString = JSON.stringify(postData);
$.ajax({
type: "POST",dataType: "json",url: "add_cart.PHP",data: {myData:dataString},contentType: "application/json; charset=utf-8",success: function(data){
alert('Items added');
},error: function(e){
console.log(e.message);
}
});
});
});
</script>
在PHP中我使用：
if(isset($_POST['myData'])){
$obj = json_decode($_POST['myData']);
//some PHP operation
}
