ajax request in jquery, data sent to the server not working - ajax

Question

var p = JSON.stringify(parameter);
console.log(p);
$.ajax({
type: 'POST',
url: 'http://abc.com/ajax.php',
data: p,
success: function(status) {
console.log(status);
}
});
console.log(p) shows {"o_fname":"hh","o_lname":"jkhk","o_email":"uifh#bjvh.com","o_phone":"","b_name":"bmnbmbm,b","b_address":"","b_city":"","b_postal":"","b_phone":""}
but in my http://abc.com/ajax.php page print_r($_POST) is giving me an empty array Array()

Answer 1

var p = JSON.stringify(parameter);
That is your problem.
When you pass string data to .ajax, it sends it “as-is” – but PHP only popuplates $_POST if it receives data encoded as application/x-www-form-urlencoded.
So don’t make your data into a string, but pass your parameter object directly as value for data – then jQuery will take care of sending it the right way, so that PHP understands what it is supposed to do with it.

Answer 2

I think park of the problem may be that in data: you're passing the parameter details, but to the function on the other side of the jQuery you're passing a parameter name and nothing else.
Try:
$.ajax({
type: 'POST',
url: 'http://abc.com/ajax.php',
data: {parametername:p},
success: function(status) {
console.log(status);
}
});
With parametername replaced with the parameter name ajax.php is expecting.
