[PHP] Re: Guestbook
Hi, you give less information. How do you compute the entry number and how do you save the entries and so on. Normally you will have to live with the gaps but sure, you can touch every entry and change its number ;-).

In the corner it keeps record of the entry number, but when I delete and entry the entries posted after it don't go back to catch up. So the entry numbers skip from 22 to 24, for example. Is there anyway to stop this happening, so if i delete an entry the next one will follow on instead of being the number it would have been if i hadn't deleted the entry?

in mysql the autoincrement field will not go back to fill gaps... and this is for a good reason ... suppose you had an entry (bogus1) in your guest book with entry number 23 and you deleted it... now a new entry comes and it is given the entry number 23 ... well this ambigus : did u delete the original one or modified it ? also people pointing to that particular entry in their sites will be confused by the change... where as in the real life we usuallay offer a record does not exist type of message ... got it ?! --- Thomas Seifert [EMAIL PROTECTED] wrote: Hi, you give less information.

Take a look at mysql_data_seek()

I have a really simple guestbook that allows someone to post to the book,
then it displays all the entries. Well, there are too many entries now for
just one page and it looks kinda wacky, so I wanted to do something where it
only displays 10 entries per page, then there are links for pages say 11-20,
21-30, etc. I have no idea how to do this - I only know how to limit the
number of entries per page. So, the script that displays all the entries
looks something like this:
$counter = 0;
$result = mysql_query(select name, post from guestbook order by id desc,
$db);
while (($myrow = mysql_fetch_row($result)) ($counter 10)) {
echo TRTD$myrow[0]/TD/TR\n;
echo TRTD$myrow[1]/TD/TR\n;
++$counter;
}
Well, that shows only the latest 10 alright, but what if I wanted to show
entries 11-20? I figure I could get the number of posts through
mysql_num_rows, I just can't piece it all together. Any suggestions would be
really helpful.
