die(mysql_error());
after the mysql_query() line just above the loop it should tell you why.
it does:
No database selected
But i selected it in the init.inc.php, doesen´t i?
<?php
mysql_connect('127.0.0.1', 'blogger', 'blog');
mysql_select_db('blog');
include ('inc/posts.inc.php');
include ('inc/comments.inc.php');
?>

Also could you post the SQL here and I will take a look
the sql should be the same as in your videos:
<?php
function valid_pid($pid){
$pid = (int)$pid;
$total = mysql_query("SELECT COUNT(`post_id`) FROM `posts` WHERE `post_id` = {$pid}");
$total = mysql_result($total, 0);
if ($total !=1){
return false;
}else{
return true;
}
}
function get_posts(){
$sql = "SELECT
`posts`.`post_id` AS `id`,
`posts`.`post_title` AS `title`,
LEFT(`posts`.`post_body`, 512) AS `preview`, `posts`.`post_user` AS `user`, DATE_FORMAT(`posts`.`post_date`,'%d/%m/%Y %H:%i:%s') AS `date`, `comments`.`total_comments`,
DATE_FORMAT(`comments`.`last_comment`, '%d/%m/%Y %H:%i:%s') AS `last_comment`
FROM `posts`
LEFT JOIN (
SELECT
`post_id`,
COUNT(`comment_id`) AS `total_comments`,
MAX(`comment_date`) AS `last_comment`
FROM `comments`
GROUP BY `post_id`
) AS `comments`
ON `posts`.`post_id` = `comments`.`post_id`
ORDER BY `posts`.`post_date` DESC";
$posts=mysql_query($sql);
$rows = array();
while (($row=mysql_fetch_assoc($posts)) !== false){
die(mysql_error());
$rows[]=array(
'id' =>$row['id'],
'title' =>$row['title'],
'user' =>$row['user'],
'date' =>$row['date'],
'preview' =>$row['preview'],
'total_comments'=>($row['total_comments']===null) ? 0: $row['total_comments'],
'last_comment' =>($row['last_comment']===null) ? 'never': $row['last_comment']
);
}
return $rows;
}
function get_post($pid){
$pid=(int)$pid;
$sql = " SELECT
`post_title` AS `title`,
`post_body` AS `body`,
`post_user` AS `user`,
`post_date` AS `date`

WHERE `post_id` ={$pid}";
$post=mysql_query($sql);
echo mysql_error();
$post=mysql_fetch_assoc($post);
$post['comments'] = get_comments($pid);
return $post;
}
function add_post($name, $title, $body){
$name = mysql_real_escape_string(htmlentities($name));
$title = mysql_real_escape_string(htmlentities($title));

}
?>
PS: wouldnt it be possible you to upload the files you wrote, which did their job
