A way to get a parameter from the URL - php

Question

I have this issue i'm trying to solve.
I have this page lista.php
In which i load another page (which refreshes every x seconds) named pagination.php
I use this script:
function LoadContent()
{
$('#lista').load('pagination.php');
}
$(document).ready(function(){
LoadContent(); //load contentent when page loads
setInterval('LoadContent()',30000); //schedule refresh
});
Well, there is this URL:
lista.php?id=3
I need the pagination.php to grab the id, but it won't work..
the pagination.php is inside lista.php... how can i solve it?
I tried the GET method..
Any suggestion please?
Thanks.

Answer 1

To obtain id from your url like lista.php?id=3 you could use
var url = window.location.href;
var queryStr = url.substring(url.indexOf("?")+1);
var id = queryStr.split('=')[1];
So the whole code maybe like:
function LoadContent()
{
var url = window.location.href;
var queryStr = url.substring(url.indexOf("?")+1);
var id = queryStr.split('=')[1];
$('#lista').load('pagination.php?id=' + id);
}
$(document).ready(function(){
LoadContent(); //load contentent when page loads
setInterval('LoadContent()',30000); //schedule refresh
});

Answer 2

Add the parameter to the url, e.g.:
function LoadContent()
{
var id = ... <== assign id here
$('#lista').load('pagination.php?id=' + id);
}
$(document).ready(function(){
LoadContent(); //load contentent when page loads
setInterval('LoadContent()',30000); //schedule refresh
});

Answer 3

If you're using AJAX to load dynamically then that's a different URL, so append the current query string to the request with something like location.search.substring(url.indexOf("?")).
$('#lista').load('pagination.php' + location.search.substring(url.indexOf("?")));

Answer 4

i think you can use this:
$('#lista').load('pagination.php?id=<?php echo $_GET['id'] ?>');
