Creating PHP Pagination

[mfoland]

I got it figured out.. but My start = 0 should be showing 1-20 on the pagination but it's showing 1-21.. Very interesting!

[KULP]

Added the compatibility with url.

PHP Code:

<?php
$cnt= 100; //set to value in database
if(isset($_GET['page']))
    $currentpage = $_GET['page'];
else
    $currentpage = 1; // Whatever you wanna use.
$current = 1;
$limit = 20; //Or set to other value, or user defined.

while($current <= $cnt)
{
    $thislast = $current + $limit;
    $url = "?page=" . $currentpage;
    if($thislast > $cnt)
    {
          $thislast = $cnt;
    }
    if($current == ((($currentpage - 1) * 20) + 1))
    {
        echo '<p class = "paginationBold">'.  $current . ' - ' . $thislast . '</p>';
    }
    else
    {
        echo '<a class = "paginationLink" href = "http://localhost/testing.php?page=' . ((int)($current / 20) + 1) . '">' .  $current . ' - ' . $thislast . '</a>' ;
    }
        $current += $limit; //Added this to update $current. Was missing.
}
?>

1 + 20 = 21

But you can easy fix that.

[mfoland]

Right.. My start is 0 because in my script above in the beginning if the start is 0 it'll show 1-20

[mfoland]

Also, I went to another page, and my first link for the 0-20 disappeared. hmm

Edit.. nevermind on that. Was experiencing with the $current value! Still figuring out how to make it say 1-20 if i'm on start.. it does goes start = 2. I need them to be by 20..

[KULP]

Try changing

$thislast = $current + $limit;

to

$thislast = $current + $limit - 1;

[mfoland]

That worked.. I'm learning.. Thanks!

Now when I click the link instead of it going by one.. I need it to still go by 20.. My start needs to be 0 for the 1-20 records to show.. So 0 + 20 obviously but then to show the next record.. that's the hard part.. I do want to think it has to do with the link area.

What? And sorry but I'm not going to code your entire site...

[mfoland]

I'm thinking while having the 1-20 say start = 0 the next would say that first number... example the 41-60 say start = 41.. I can think of it, but to code it, is the hard part, well with the pagination. It is a learning experience for me!

[mfoland]

This is the only project I need help with.. How do I get the page to increase or decrease by say 20.. On the links I need it to echo the <?=$current?> so if I click 41-60 the page would say 41

What do you mean by 'the page would say 41'

?page=41

That!

So when I click on the link it goes by 20s instead of one.

EDIT.. I'll give you an example.. The default is page= 0 so 1-20 should be bold.. although it doesn't for that. But then if I click 21-40 the page variable will be ?page=21, and so on.

That can be changed but... why?... Is the rest of the page already coded to work that way or something?

Yes it is..

[KULP]

Well you're almost there, just change a few things. I think you can play around with it enough.

The only thing I could think of is if I change the +1 in the link to say $current it'd work, but it didn't even work.. That's why I sent the reply asking for help as to what to change.
