Php Page Display help

[Lenny]

Trouble figuring this one out. Trying to get in touch with guy who coded it but cant so asking your help here.

Take a look t this page Poker News | Casino News | Gambling News | Online Gambling News | Online Poker | see how on the bottem it showing all 190 different news pages, I would like to change that to show only the next few such as Poker News | Online Poker News | PokerNews see how it shows 1-10 then it changes as you go to different pages such as 2-11 or 10-20. This is the code on the page on my site which controls the page showing display, can you let me know what i would need to change to fix it .

Thanks

<?
if($page > 1){
$prev = ($page - 1);
echo "<a href=news.php?page=$prev class='yellow_link'>Previous</a> ";
}
for($i = 1; $i <= $total_pages; $i++){
if(($page) == $i){
echo "$i ";
} else {
echo "<a href=news.php?page=$i class='yellow_link'>$i</a> ";
}
}
// Build Next Link
if($page < $total_pages){
$next = ($page + 1);
echo "<a href=news.php?page=$next class='yellow_link'>Next</a>";
}
echo "</center>";
?>

Try adding single quotes around the URLs. You are already using single quotes on the "class" portion; try using them on the "href" part, too.

Old way:

echo "<a href=news.php?page=$prev class='yellow_link'>Previous</a> ";

Try this instead:

echo "<a href='news.php?page=$prev' class='yellow_link'>Previous</a> ";

Thanks for the look engineer.
Think i have not explained myself correctly as I myself do not know what im talking about.

After much searching found out this is called "pagenation"

What im trying to do is just to show a range of news pages instead of all of them. So trying in the pages to show only current page and a few previous ones and a few future ones.

What i think im trying to do is Set the number of page links to show on either side of the current page. Currently no matter what news page your on it shows all news page links.

How comfortable are you with changing the code? If you want you could look at the code on this link xxhttp://www.webmasterworld.com/php/3506050.htm which is pretty close to what you want, but might take a bit of messing around.

nah, dont want to mess around changing things. Thanks for the info i forgot about them, will post my question there,

Thankyou.

Your numbered pages are built using the "for" loop in the above code. I don't have access to your full code but I'm guessing some simple change to that line will make the difference.

for($i = $page-2; $i <= $page+8; $i++){ 

To explain the way "for" loops work, there are 3 variables, usually expressed as ($i = beginning number; $i = ending number; $i = increment in counting).

Your orginal code counted from 1 ($i = 1) to greater than or equal to the total number of pages ($i <= $total_pages) using increments of 1 ($i++).

I changed it to count from current page - 2 pages ($i = $page-2) to greater than or equal to current page plus 8 pages ($i <= $page+8) using increments of 1 ($i++)

My code is not going to be perfect but it may get you started in the right direction.

Mike, thanks that seems to work except for one problem. If your on page 1 or 2 When it reads the back pages it goes into the negative showing page numbers 0 and -1

i changed the bold part to 10 and 10 , so if your on page 3 it shows 0 and -1 - -7

Any way for it to not show before the first page?

for($i = $page-2; $i <= $page+8; $i++){

[Mike]

pm'd you

All Fixed, Thanks Mike
