All rightey. Here it goes in it's (almost) full glory!
// The nav-function that's responsible for updateing the query
if($nav) {
if($go=="next") {
if($page < $nr_pages && $page >= 0) {
$page++;
$milla= (($page) * 20).","; // replace with
echo "millä: " . $milla; // echo out debug info
$mita = (($page-1) * 20).","; // replace what
echo "mitä: " .$mita; // echo out more debug info
$query=ereg_replace($mita,$milla,$query);
}
}
if($go=="prev") {
if($page>=1 && $page <= $nr_pages) {
$page--;
$milla = (($page) * 20).",";
echo "millä: " . $milla;
$mita = (($page+1) * 20).",";
echo "mitä: " . $mita;
$query=ereg_replace($mita,$milla,$query);
}
}
echo "query from nav(): " .$query;
$result=mysql_query($query,$database)
or die("BEATCH,WHINE AND MOAN!"); // hehe. just a debug output.
print_taulukko();
}
function print_taulukko() {
?>
<FORM ACTION="page.php" METHOD="POST">
<?
//debug
echo "query: " . $query;
echo "<BR><BR>";
echo "page: " . $page;
echo "<BR>";
echo "nr_pages: " .$nr_pages;
//endof debug
while($row=mysql_fetch_row($result)) {
[snip away stuff that doesn't really matter]
}
?>

}
And that's basically it. There's a function responsible for
reading user input and constructing the sql-query, and it
places the sql in $query, stuffs it down MySQL and throws
it over to print_taulukko(), and it seems to be working right,
since the first result always is the correct one. It also session_registers
$query. (yes, I use session_register("query"), not session_register($query).)
I checked the sess_<whatever> file step by step when testing again just to see
exactly what is put in it, but it seems to be a well-behaved little textfile.
Make any sense out of the code?
Cheers mate,
Markus
