I'm new in PHP/jquery
I would like to ask how to send json data from a form field like (name, age, etc) with ajax in a json format. Sadly I can't found any relevant information about this it's even possible to do it dynamically? Google searches only gives back answers like build up the data manually. like: name: X Y, age: 32, and so on.
Is there anyway to do that?
Thanks for the help!
Edit:
<form action="test.php" method="post">
Name: <input type="text" name="name"><br>
Age: <input type="text" name="email"><br>
FavColor: <input type="text" name="favc"><br>
<input type="submit">
</form>

here is a simple one
here is my test.php for testing only
<?php
// this is just a test
//send back to the ajax request the request
echo json_encode($_POST);
here is my index.html
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<form id="form" action="" method="post">
Name: <input type="text" name="name"><br>
Age: <input type="text" name="email"><br>
FavColor: <input type="text" name="favc"><br>
<input id="submit" type="button" name="submit" value="submit">
</form>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script>
$(document).ready(function(){
// click on button submit
$("#submit").on('click', function(){
// send ajax
$.ajax({
url: 'test.php', // url where to submit the request
type : "POST", // type of action POST || GET
dataType : 'json', // data type
data : $("#form").serialize(), // post data || get data
success : function(result) {
// you can see the result from the console
// tab of the developer tools
console.log(result);
},
error: function(xhr, resp, text) {
console.log(xhr, resp, text);
}
})
});
});
</script>
</body>
</html>
Both file are place in the same directory

The accepted answer here indeed makes a json from a form, but the json contents is really a string with url-encoded contents.
To make a more realistic json POST, use some solution from Serialize form data to JSON to make formToJson function and add contentType: 'application/json;charset=UTF-8' to the jQuery ajax call parameters.
$.ajax({
url: 'test.php',
type: "POST",
dataType: 'json',
data: formToJson($("form")),
contentType: 'application/json;charset=UTF-8',
...
})
