[SOLVED] page numbers

[squiblo]

i have a pagination script working fine but the numbers at the bottom do not indicate what page i am currently on, how can change this to show that i am currently on page 5 for example by making the number 5 bold or underlined

 

<?php
for ($i=1; $i<=$maxPages; $i++)
   echo ($i === $page) ? $i .' ' : '<a href="?page='. $i . (strlen($search) ? '&search=' . $search : '') .'" class="pagenumbers">'. $i .'</a> ';
?>

Actually it is indicating it already now, it is not printing the current page as link now. But the code below would change it not a link and bolded.

 

echo ($i === $page) ? '<strong>' . $i .'</strong> ' : '<a href="?page='. $i . (strlen($search) ? '&search=' . $search : '') .'" class="pagenumbers">'. $i .'</a> ';

indicating what page i am on is perfect now, the last thing is only echoing 10 page numbers at a time when $maxPages => 10

Changing that piece of code should have not affected anything else but bolding the page number if its current. I tested it and for me it prints all pages no matter how many there are. This is the code I tested and it works.

 

<?php
// Print pages
for ($i=1; $i<=$maxPages; $i++)
{
echo ($i === $page) ? '<strong>' . $i .'</strong> ' : '<a href="?page='. $i . (strlen($search) ? '&search=' . $search : '') .'">'. $i .'</a> ';
}

sorry ill explain it a bit better, the page numbers below the results are infinate depending on the amount of results and the results per page, the page numbers can go above ten but i do not think that is user friendly... i tried this but on the 10th page the option to click next is not linked and will not allow you to view page 11...

 

$maxPages = ceil($foundnum / $perPage); //may come out as a decimal 
if ($maxPages > 10)
$maxPages = 10;

[premiso]

Well you are checking if maxpages is greater than 10, if it is you set it to 10...why would it goto 11 given that logic?

[squiblo]

that is why i need help with it, i understand why the page will not goto 11, on the 1st page i would like the page numbers shown like "1 2 3 4 5 6 7 8 9 10" but the second page to show "2 3 4 5 6 7 8 9 10 11"

[TeNDoLLA]

You probably should code the paging like that it would print out something like this, say you are on the page 10 and the print will be: prev ... 8 9 10 11 12 ... next. And make it dynamic. But I don't have the time to do everything for you ready. Maybe someone else has. There is still plenty of tutorials that show how to do this if you search on google. And I think I had a paging class somewhere if you want I can find and post it here. It had this functionality and some others also.

 

Edit: but I think the class might not help but instead make it more complicated. So it might be a good idea to try to understand and learn the current code and try modifying it. Or follow some tutorial.

[squiblo]

if you could post the class im sure i would find it very useful thank you for your help

First of all a WARNING, this class was created once for a specific app and thats why it might not be optimal to all apps. Also this might break a little concepts of OOP but here goes.

And usage for example

<?php
$currentPage = 10;
$maxPages = 20;

$paging = new Pager($maxPages, null, $currentPage, null, null, true);
echo $paging->init();

 

Of course you calculate the maxpages and currentpage etc. based on your queries. And might modify the url if needed. Plus some other stuff which is not so well commented.
