deleting an account using multiple ajax requests

deleting an account using multiple ajax requests

The user, upon clicking a button(delete) is given the option to delete his
account-he must enter his password also to do that. So I am describing
above the 1st ajax request which is made.WHat is returned from the server
is a response if there are still bookings(it is a booking web app) made
from the user and if he should reconsider-a message appears.
If he insists deleting his account then he must click the delete button
again. The problem(if you have not noticed) is that by clicking again the
delete button the above procedure is repeated while the aim now-after the
warning message appears-is that the click of the delete button means "yes,
despite the bookings I want to delete my account".
So, this delete button must have dual role, one before the warning appear
and one after the warning. What can I do in a situation like this?I was
thinking implementing a confirm box but the above are all taking place in
a modal box.So a confirm box over a modal I do not think is the correct
solution.
Here is the ajax request that is sent when the user first clicks the
delete button:
$('.deactivate').click(function(){
event.preventDefault();
var trimmeddelpass=$.trim($('input#del_password').val());
if(trimmeddelpass!=="")
{ $.ajax({
type: "POST",
url: "delaccountajax.php",
data: {"delpass":trimmeddelpass},
success:function(data){
if(data==2)
{$('#warning').html('You have still bookings pending');
$('#warning').show();
}
else if(data==3)
{ window.location.href = "../Frontend/login.php";//proceed
deleting the account
}
error:function(jxhr){
alert(jxhr.responseText);}
});
}
Here is the server code:
$output=delete_account($conn,$delpass,$sessionml);
if($output=='2')
{$success='2';}
elseif($output=='3')
{logout();
$success='3';}
echo $success;
Both of the codes above are simplified versions involved since some other
stuff were in them too,-they are not needed though for the issue we are
dealing.
