dataType: “json” won't work

Question

I\'m trying to send back multiple variables from a php file to ajax using json in an array. The code in the php file works perfectly and does everything with my database lik

Answer 1

I believe if you use dataType you should be using contentType, "The official Internet media type for JSON is application/json".

.ajax(
{
 url: 'UpdateComments.php',
 type: 'POST',
 contentType: "application/json",//note the contentType defintion
 dataType: "json",
 data: 
 {
   type: "add",
   comment: $("#comment").val(),
   id: videoID  
 },
 success: function (data) 
 {
   //Get the data variables from json and display them on page
 }
});
