Post variable before redirect? - php

Question

I am currently building on a CMS. I want to send a page-id or site-id to the next page on redirect. I tried doing it using the jQuery POST function:
$(document).ready(function(){
$('.sender').on('click','a',function(){
var url = $(this).attr('href');
var n = url.indexOf('#')+1;
var siteid = url.substr(n,url.length);
$.ajax({
url: 'pages.php',
type: 'POST',
data: { siteid:siteid },
success: function(response){
console.log('check');
},
error: function(){
console.log('error');
}
});
});
});
But because the request is sent at the same time as the redirect, it does not seems to work.
Because I am using the apache rewrite_engine to redirect stuff, I cannot use GET.
Apart from session_variables, what are my options?
I want to keep it safe, so I don't want much info to be visible/available!

To achieve this you need to wait for the AJAX request to complete before the page is redirected. Try this:
$(document).ready(function(){
$('.sender').on('click', 'a', function(e){
e.preventDefault(); // stop the default redirect
var url = $(this).attr('href');
var n = url.indexOf('#') + 1;
var siteid = url.substr(n, url.length);
$.ajax({
url: 'pages.php',
type: 'POST',
data: {
siteid: siteid
},
success: function(response){
console.log('check');
window.location.assign(url); // redirect once the AJAX has successfully completed
},
error: function(){
console.log('error');
}
});
});
});

I'm not sure to clearly understand why you need but I think this can answer your problem.
If what you need is to transfert informations using a real POST method, just create an hidden form with method="POST" and fill it on click event.
<script type="text/javascript">
$(document).ready(function(){
$('.sender').on('click','a',function(event){
event.preventDefault();
var url = $(this).attr('href');
var n = url.indexOf('#')+1;
var siteid = url.substr(n,url.length);
$('input[name="siteid"]').val(siteid);
$('#redirectForm').submit();
});
});
</script>
<form id="redirectForm" action="pages.php" method="POST">
<input type="hidden" name="siteid" value=""/>
</form>
