At the moment I save data when changes are made on the page using ordinary PHP but of course it makes the page reload every time which resets everything. I really need to do it without page reload. I've heard its possible to do with Ajax and JQuery. I would much prefer Jquery answers rather than Javascript.

for example you have this form
<input type="text" name="name" class="abc" id="test" placeholder="Name"> <a href="#" class="PopUpSendBtn" id="sendinfo">Send</a>
then write Script
<script> $(document).ready(function() { // invoke event on clicking send button $("#sendinfo").on("click", function(evt) { // get value of input field var userName = $('#test').val(); jQuery.ajax({ url: filename.php, type:'POST', async: false, data:{'userName':userName}, success: function(output_string){ // alert(output_string); if(output_string == 1){ // do someting } else { // do someting } } , error: function(object, status, response) { alert(response); } }); }); }); </script>
your php file(filename.php) get data using post request
$data = $_POST['userName']; // query to store data in db // after saving data successfully in db your can send back a success message //in json or any other format (in my case i am using json) $data['success'] = TRUE; echo json_encode($data);
Don't forget to include jquery script.
This is the basic idea how to send data using ajax. You can modify it according to your requirements.
