Calling a php function with a button by using jquery - php

Question

I'm trying to figure out how to call a PHP function with a html button as i understand so far i can't use javascript since it client side but would it work with jquery and how so?
Here my button
<button type="button" class="btn btn-default" data-dismiss="modal">Yes</button>
And here is my function in php
function confirmCloseTicket($conn) {
if (isset($_GET['deleteticketid'])) {
$id = $_GET['deleteticketid'];
$statuschange = "Closed Ticket";
$sql = "INSERT INTO closedtickets SELECT * FROM ticket WHERE ticketID = $id;";
$sql .= "DELETE FROM ticket WHERE ticketID = $id;";
$sql .= "UPDATE closedtickets SET status = '$statuschange' WHERE closedtickets.ticketID = $id;";
$result = mysqli_multi_query($conn, $sql);
if($result) {
header("location: http://localhost/ticketSystem/viewticket.php");
exit();
}else {
echo "failed";
}
}
}

I figure it out with this method:
Starting of to create a button using <a> tag and give it AN ID "Verify-Email" you can call it what ever you want just remember it!
HTML:
Verify Now!
In jquery or inside a <script></script> tag i call ID "#verify-email". also using # it tells is a ID and not a class, if you were using a class it would look like this.
".verify-email"
Then i'm using a .click(function(e){ a bassic click do function.
then i'm using e.preventDefault(); to prevent the page to refresh while we doing this click function by pressing the button from the page.
then i'm using a $.ajax({ }); reuqest to call it to POST Method.
as you can see inside my Ajax i have URL, method and DATA, what i have done i have called an action : 'verify-email' see step 6. how i GET that POST inside php.
jquery:
$("#verify-email").click(function(e) {
e.preventDefault();
$(this).text('Please Wait...');
$.ajax({
url: 'assets/php/process.php',
method: 'POST',
data: { action: 'verify-email' },
success:function(response){
$("#verifyEmailAlert").html(response);
$("#verify-email").text('Verify Now');
}
});
});
inside here i have a isset function by verify super global variable $_POST['action] and also checking it again with 'verify-email' both of those values need to be same as $.ajax method
process.php:
if (isset($_POST['action']) && $_POST['action'] == 'verify-email') {
// need to create a varible for "verify-email"
$Getemail = $_POST['verify-email'];
then call the function
}
