Estoy teniendo un problema que me tiene rompiendo la cabeza ya varios dias, estoy programando un muro (tipo facebook) y tengo dos problemas que no eh podido solucionar y ojala pudieran orientarme.
Problema #1. El scroll automatico no funciona correctamente, debería de mostrar los datos que le siguen al último post pero vuelve a mostrar los mismos datos en todas las paginas que le des para abajo.
Problema #2. Despues de bajar el scroll y que se vuelven a mostrar los datos repetidos ya no puedo interactuar con ellos como comentarlos o darle like porque me dice que el formulario esta vacío.
Dejo el código del wall.php
Código:
<?php
include_once("header.php");
$limit = 5; #item per page
$user_id = $_SESSION['user_id'];
$page = (int) (!isset($_GET['p'])) ? 1 : $_GET['p'];
# sql query
$sql = "SELECT p.*,u.name as username, pl.like_id from fb_post p left join fb_users u on u.user_id = p.user_id left join fb_post_likes pl on pl.post_id = p.post_id and pl.user_id = '$user_id' group by p.post_id order by post_id desc";
# find out query stat point
$start = ($page * $limit) - $limit;
# query for page navigation
if( mysql_num_rows(mysql_query($sql)) > ($page * $limit) ){
$next = $page + 1;
}
$query = mysql_query( $sql . " LIMIT {$start}, {$limit}");
if (mysql_num_rows($query) < 1) {
header('HTTP/1.0 404 Not Found');
echo 'Page not found!';
exit();
}
if(!isset($_SESSION['user_id']) || $_SESSION['user_id'] == ""){
header("location:index.php");
}

Siento que el problema se soluciona simple en el Ajax (ya que no soy muy bueno) y algo me dice que solucionando el primer problema se arregla el segundo, pero ya probe de todo y no lo hago funcionar, espero puedan ayudarme, saludos y gracias.
