I've got one of those problems that you know the problem is simple, but
you've been staring at it for too long to make sense anymore.
Basically, I have the following function to help step through a database
by displaying Previous and Next links, depending on some variable sent
to it.
function pagination($start, $num_rows,$file,$limit) {
if(empty($limit)) {
$limit = 20;
}
if($start ==0) {
$previous_link = " ";
} else {
$start = $start - $limit;
$previous_link = "<a
href=\"$file?start=$start\">Previous Entries</a>";
}
if($num_rows > ($start + $limit)) {
$start = $start + $limit;
$next_link = "<a href=\"$file?start=$start\">Next
Entries</a>";
} else {
$next_link = " ";
}
echo "<table width=\"100%\">
<tr>
<td width=\"50%\"
align=\"center\">$previous_link</td>
<td width=\"50%\"
align=\"center\">$next_link</td>
</tr>
</table>";
}
So $start is where to start retrieving items from the db. $num_rows is
how many rows there are in the DB. $file is the file calling it and
$limit is how many rows per page to display.
The problem I'm having is that when calling the function with:
pagination(5,10,"file",5);
The next link continually displays. This should be incorrect as 10
($num_rows) is not greater than 10 ($start + $limit. Any suggestions
will be appreciated.
Thanks,
Conor
