2 Guestbook Questions

spires · June 28, 2006

Hi, I'm building my first guestbook and have come across 2 problems.

[a href=\"http://www.spirestest.com/login2\" target=\"_blank\"]My Webpage[/a]

1st, the database will not add the latest post to the front (1st page), They all attach to the end of the rest of the posts. I have tryed 'ORDER by DATE ASC' 'ORDER by DATE DESC' and 'ORDER by DATE'

None of these seem to work.

2nd, I've built a navigation for the guestbook. The PREV button and the Numbers all work fine. But i dont know how to get the NEXT button to not display on the final page. At the moment you can go upto page 1000.

I hope this all makes sence. please goto [a href=\"http://www.spirestest.com/login2\" target=\"_blank\"]My Webpage[/a]
and click on guest book.

Any help would be great.
Thanks

Here is my code.

include('db.php');
include('validation.php');

I'd use the id field if you have set one up, rather than ordering by date. adn you'll want to use this:
ORDER by `post_id` DESC

About your pages thing you'll probably want to change this:
[code]if ($offset < 1000) {[/code]
to the following:
[code]if ($offset < $pages) {[/code]
$pages is the variable you setup for the max number of pages.

Also you might want to chnage this:
[code]$count = mysql_num_rows($result);

for ($i = 0; $i < $count; $i++) {
$row = mysql_fetch_array($result);[/code]
to the following:
[code]$count = mysql_num_rows($result);

if($count < 1)
{
    echo "No entries in guestbook"
}
else
{
    while($row = mysql_fetch_array($result);

    // rest of your guestbook code here
}[/code]
