Matt,
Here's how I did the "20 results per page". Messy, I know, but
it was the only way I figured out how to do it.
$query="SELECT * FROM table";
$result=mysql_query($query,$database);
$nr=mysql_num_rows($result);
/* Here you can slap in a check for how many results
you want, ie:
*/
if($nr>200) {
die("Bitch,whine and moan!");
}
$nr_pages=(ceil($nr/20));
Or, you could, in the first SELECT statement put in a
LIMIT 200, I suppose that would work, too.
I'd have to dig into this myself too, as my database will
have a tad over 100 000 records when it's done.
Then I have two buttons, prev & next that's got a little
javascript slapped on them;
<INPUT TYPE=button VALUE="previous page"
onclick="parent.location='nav.php?nav=true&go=prev';">
etc.
Then, in nav.php:
if($go=="next") {
if($page < $nr_pages && $page >= 0) {
$page++;
$with= (($page) * 20).",";
$what = (($page-1) * 20).",";
$query=ereg_replace($what,$with,$query);
}
}
if($go=="prev") {
if($page>=1 && $page <= $nr_pages) {
$page--;
$with = (($page) * 20).",";
$what = (($page+1) * 20).",";
$query=ereg_replace($what,$with,$query);
}
}
$result=mysql_query($query,$database)
print_table(); //processes the query
If you got any questions regarding my code,
please do drop me a mail.
Cheers,
Markus
