jQuery Ajax POST JSON问题

Question

I'm trying to pass a JavaScript array into a PHP script to then be put into a database but I'm having issues. I have used JSON.stringify on the array before sending. The request seems to work in that when stepping through the code debugging the php page is called but no data is passed into the POST global. I'm sure its something amateurish that I've missed but I'm struggling. This is the code:-

$.ajax({
    type: "POST",
    datatype: "json",
    url: "processdraw.php",
    data: {
        json: pDrawnTeams
    },
    contentType: "application/json; charset=utf-8",
    success: alert('worked')
})

If you are not getting any error in your javascript, make sure that you are getting that parameter like this in your php target file:

$myJSON = $_POST['json']; // ['parameter name']

after that you will need to decode that json

$myData = json_decode($myJSON, true) // true is for retrieving as an array
