Hi,
i have a sql statement that has over 100 entries. Im not the best at PHP but understand it quite well. How do i spreed these over a number of pages i.e have only 15 per page or so so there is page numbers at the bottom of how many pages there are.
If any1 has any tuts on it or can shed some light on it, that would be great.
Thanks Adam
[code=php]
<?PHP
$id = 100;
/* $id is the maximum number of entries
This would be the number you would to grabe the correct row.
*/
if(isset($_GET['ent']) && is_numeric($_GET['ent']) && $_GET['ent'] <= $id) {$start=$_GET['ent'];} else {$start=$id;}
for($x=$start; $x>0; $x--)
{
/* necessary database interaction here. Display entries here as well.*/
echo($x."<br />n");
// at the 15'th entry, displays next and/or back links.
if($x==$start-14 && $x>1)
{
if($start<=$id-15){echo("<a href="page.php?ent=".($x+($start-$x+15))."">Back</a> | ");}
echo("<a href="page.php?ent=".($x-1)."">Next</a>");
break;
}
if($x==1 && $start < $id){echo("<a href="page.php?ent=".($x+($start-$x+15))."">Back</a>");}
}
