How to get JSON data in ajax.php page?

Question

I am sending email using ajax JSON.

Code:

var lookup = {
            'name': fname,
            'email': email,
            'items': [{
                'message': message,
                'value': itemValue
            }]
        }
        $.ajax({
            type: 'post',
            url: 'ajax.php',
            data: JSON.stringify(lookup),
            success: function(data){
                alert(data);
            },
            contentType: 'application/json',
            dataType: 'json'
        });

My data is going to JSON format

{"name":"Chinmay","email":"[email protected]","items":[{"message":"Bla Bla Bla!!!","value":"100"}]}

In my ajax.php page how to get the name, email, message and value?

ok, so first lookup $.ajax. You made a POST request with lookup (which jQuery automatically converts, so you can safe some code). Now I look up sth like "php post" and am already linked to the official manual on $_POST — kero

Since you're posting the data as JSON, you have to deserialize the raw post data:

$data = json_decode(file_get_contents("php://input"), true);
echo $data['name'];

That is not going to work. The data argument needs key - value pairs, so you could do something like:

data: {json_string: JSON.stringify(lookup)},

and in php:

$data_array = json_decode($_POST['json_string']);

Although normally you would just send the form to your php (if possible) file without having to build the data-structure yourself:

data: $('form').serialize(),

and then in php you can do something like:

$name = $_POST['fname'];
