How to retrieve the value sent by a $.ajax function in my php file?

I get the following error on the .php page. Notice: Undefined index: name
$.ajax({
url: 'test.php',
type: "GET",
data: ({name: "James"}),
success: function(data){
console.log(data);
}
});
I am trying to get the value sent from the data object in the test.php file as follows:
if(isset($_GET['name'])){
echo $_GET['name'];
} else {
echo "Not working";
}

Try this :
data: {name: "James"},
Instead of
data: ({name: "James"}),

You can use serialize for accommodate your data
example :
var serializedData = 'name=James';
$.post('test.php', serializedData,
function (enumData) {
console.log(enumData);
}
);
hope this helps you. cheers :)

I suspect it's something wrong with the jQuery part. Try to make the data a valid JSON object data: {"name": "James"} (notice how "name" is enclosed in quotes):
$.ajax({
url: "test.php",
type: "POST",
data: {"name": "James"},
success: function(data){
console.log(data);
}
});
Edit: Removed dataType. As Taplar pointed out, this is linked to the returned data.

Why is my JQuery variable not sending to php?

I have a variable which contains data, i'm then using a ajax function to send this variable data to this php file. I'm slightly unsure I can store this variable into php and echo it out. This is the code that I currently have...
var data = 1
// Sending this data via ajax to php file/
$.ajax({
type: 'post',
cache: false ,
url: 'function.php',
data: data,
success: function(data) {
alert ( data );
}
});
This is my php code
$noteone = $_POST['data'];
echo $noteone;
Any help would greatly be appreciated

data of your ajax call should be like below. Hope it will solve your problem.
data: { "data": data }

You also need to set the data type:
var data = 1
// Sending this data via ajax to php file/
$.ajax({
type: 'post',
cache: false ,
url: 'function.php',
data: { "data": data },
dataType: "json", // <---- THIS ONE
success: function(data) {
alert ( data );
}
});

Try this :
var data = 1
// Sending this data via ajax to php file/
$.ajax({
type: 'post',
cache: false ,
url: 'function.php',
data: JSON.stringify(data),
contentType: "application/json",
success: function(data) {
alert ( data );
}
});

PHP requires data to be submitted in key=value format when building $_POST/$_GET. You didn't do that. You only submitted value, so PHP has no key to populate $_POST with. You need to have:
data: { "whatever_you_want": data }
which becomes
$_POST['whatever_you_want']

How to pass data using jQuery/ Ajax to a URL

How to pass the fetched data using $.get() from a URL to a particular URL with query_string that can be retrieved using $_GET() in PHP. I'm using following but not working. I want to pass the fetched data into following parameter http://example.com/data?data=FETECHED_DATA
<?php
$ip_address=$_SERVER['REMOTE_ADDR'];
echo '<script>
$.get( "http://ipinfo.io/'.$ip_address.'/org", function( data ) {
$.ajax({
type: "GET",
url: "http://example.com/data",
data: data,
success: success,
dataType: dataType
});
});
</script>';?>
Well, don't recommended PHP to fetch and send data

I believe this will do what you want
<?php
$ip_address=$_SERVER['REMOTE_ADDR'];
echo '<script>
$.get("http://ipinfo.io/'.$ip_address.'/org", function(data) {
$.ajax({
type: "GET",
url: "http://example.com/data",
data: {data : data},
success: success,
dataType: dataType
});
});
</script>';?>
the only change is data: data changed to data: {data: data}
that's a lot of data :p
see this cut down mock up, http://jsfiddle.net/cm8o5dk8/ if you have a decent browser that can show you the network "usage" you'll see that the mockup fails trying to GET http://example.com/data?data=AS15169+Google+Inc.%0A - the %0A comes back from ipinfo.io

Thanks it worked
$.get("http://ipinfo.io/8.8.8.8/org", function(data) {
$.ajax({
type: "GET",
url: "http://example.com/data",
data: {data : data},
success: function() {},
dataType: 'json'
});
});

How to get json data coming from ajax and show it prefilled in input box

Following is the code that Ii have used to get the response in json.
but when I add alert alert(response.Subject); it returns "undefined"
HTML:
<input type="text" id="subject" value='Subject'>
Javascript:
$.ajax({
url: "/ebays/prefilledcontentajax",
type: "POST",
cache: false,
async: true,
data: {
Type: $("#Type").val(),
},
success: function (response) {
console.log(response); // it show the json that response returns. I want to show in the input box prefilled with the data that response return
}
});
please help me out.

You can use val to set value in the textbox
$('#subject').val(response[0].Subject);
Also, you might want to change the ajax call:
$.ajax({
url: "/ebays/prefilledcontentajax",
type: "POST",
cache: false,
async: true,
data: {
Type: $("#Type").val(),
},
dataType: "json",
// ^^^^^^^^^^^^^
success: function (response) {
// response is JSON
$('#subject').val(response[0].Subject);
}
});
val
Set the value of each element in the set of matched elements.
http://api.jquery.com/val/#val2
ajax
Perform an asynchronous HTTP (Ajax) request.
http://api.jquery.com/jQuery.ajax/

It really depends the construction of your JSON object, but standart is responseText that you parse with JS
maybe you try to get the response text or response JSON
$.ajax({
url: "/ebays/prefilledcontentajax",
type: "POST",
cache: false,
async: true,
data: {
Type: $("#Type").val(),
},
success: function (response) {
console.log(JSON.parse(response.responseText));
//or
console.log(JSON.parse(response.responseJSON));
}
});

you can write like this:
$('#subject').val(response.Subject);

I thinks it's really easy. Just add:
$('#subject').val(response.Subject);
in your success handler.

why cant i get the json object out of the url

I have this url which brings back the yahoo time...im guessing the PST
so i need to get this value with javascript...here is my code
$j.ajax({
type: "GET",
url: "http://developer.yahooapis.com/TimeService/V1/getTime?appid=YahooDemo&output=json",
dataType: "jsonp",
complete: function(data){
console.log(data);
}
});
but i cant seem to pull out that Timestamp out of the json...what am I doing wrong

You're using the complete method, which returns the XHR object, not the result.
You want success:
$j.ajax({
type: "GET",
url: "http://developer.yahooapis.com/TimeService/V1/getTime?appid=YahooDemo&output=json",
dataType: "jsonp",
success: function(data){
console.log(data.Response.Timestamp);
}
});
Source: http://api.jquery.com/jQuery.ajax/

I think you want to use the success callback:
$j.ajax({
type: "GET",
url: "http://developer.yahooapis.com/TimeService/V1/getTime?appid=YahooDemo&output=json",
dataType: "jsonp",
success: function(data,status,xhr){
console.log(data.Result.Timestamp);
}
});​

The JSON looks like {"Result":{"Timestamp":1331089290}}. That is, an object property called Result, which is another object literal containing the property Timestamp:
// Use .success rather than .complete
success: function(data){
console.log(data.Result.Timestamp);
}

javascript:
//change
dataType: "jsonp",
//to
dataType: "json",
Then extract the timestamp with data.Result.Timestamp.
When you use the value, remember that UNIX timestamp is in seconds whilst the javascript Date object works in milliseconds.
