Had just finished developing a hack, and realized over time that the pages in the admin cp would become quite long if they weren't paginated, so I ventured into the modcp/banning.php file to help me out...

This article is for hack authors, and presumes you are familiar with vBulletin and PHP in general.

First block of code...
PHP Code:
    $vbulletin->input->clean_array_gpc('r', array(
        'pagenumber'   => TYPE_UINT,
    ));

    $perpage = 25;//number of results per page
    if(!$vbulletin->GPC['pagenumber']){
        $vbulletin->GPC['pagenumber'] = 1;
    }
    $start = ($vbulletin->GPC['pagenumber'] - 1) * $perpage;

    //count the number of rows
    $rewardscount = $db->query_first("
        SELECT COUNT(*) AS count
        FROM " . TABLE_PREFIX . "table_name
    ");    
        
    $pagecount = ceil($rewardscount['count'] / $perpage);
Things to change are the $perpage variable, the table_name.

Then the output of the pagination...
PHP Code:
        if($pagecount > 1){
            $pagenav = "<strong>$vbphrase[go_to_page]</strong>";
            for ($thispage = 1; $thispage <= $pagecount; $thispage++){
                if($thispage == $vbulletin->GPC['pagenumber']){
                    $pagenav .= " <strong>[$thispage]</strong> ";
                } else {
                    $pagenav .= " <a href=\"incent_admin.php?$session[sessionurl]do=rewards&amp;page=$thispage\" class=\"normal\">$thispage</a> "; //your admin cp page and do=
                }
            }

            print_description_row($pagenav, false, 4, '', 'right'); //change 4 to your colspan
        }
Here you have to change incent_admin.php to your filename and the do=, and the 4 in the print_description_row.

Then there's your query:
PHP Code:
        $getrewards = $db->query_read("
            SELECT rewardid, name, points, cost
            FROM " . TABLE_PREFIX . "table_name
            ORDER BY rewardid ASC
            LIMIT $start, $perpage            
        ");
All you just need to add to your query is the LIMIT $start, $perpage.

If you've done it correctly you should have page navigation on your admin cp page.


Here's the code in full from one of my pages, if you don't understand anything above:
PHP Code:
    $vbulletin->input->clean_array_gpc('r', array(
        'pagenumber'   => TYPE_UINT,
    ));

    $perpage = 25;
    if(!$vbulletin->GPC['pagenumber']){
        $vbulletin->GPC['pagenumber'] = 1;
    }
    $start = ($vbulletin->GPC['pagenumber'] - 1) * $perpage;

    $rewardscount = $db->query_first("
        SELECT COUNT(rewardid) AS count
        FROM " . TABLE_PREFIX . "incent_rewards
    ");    
        
    $pagecount = ceil($rewardscount['count'] / $perpage);
        
    print_table_start();
    print_table_header("Incent Rewards", 4, 0, '', 'center', 0);
    echo '<tr><td align="center" class="thead">Reward</td>';
    echo '<td align="center" class="thead">Points Required</td>';
    echo '<td align="center" class="thead">Cost</td>';    
    echo '<td align="center" class="thead">Info</td></tr>';
        if($pagecount > 1){
            $pagenav = "<strong>$vbphrase[go_to_page]</strong>";
            for ($thispage = 1; $thispage <= $pagecount; $thispage++){
                if($thispage == $vbulletin->GPC['pagenumber']){
                    $pagenav .= " <strong>[$thispage]</strong> ";
                } else {
                    $pagenav .= " <a href=\"incent_admin.php?$session[sessionurl]do=rewards&amp;page=$thispage\" class=\"normal\">$thispage</a> ";
                }
            }

            print_description_row($pagenav, false, 4, '', 'right');
        }
        $getrewards = $db->query_read("
            SELECT rewardid, name, points, cost
            FROM " . TABLE_PREFIX . "incent_rewards
            ORDER BY rewardid ASC
            LIMIT $start, $perpage            
        ");
            while($reward = $db->fetch_array($getrewards)){
                $cell[1] .= "<a href=\"incent_admin.php?do=edit_reward&rewardid=$reward[rewardid]\">$reward[name]</a>";
                $cell[2] .= "$reward[points]";
                $cell[3] .= "$reward[cost]";
                $cell[4] .= "<a href=\"incent_admin.php?do=reward_stats&rewardid=$reward[rewardid]\">Stats</a> / <a href=\"incent_admin.php?do=edit_reward&rewardid=$reward[rewardid]\">Edit</a> / <a onclick=\"return confirm('Are you sure you want to delete this reward?');\" href=\"incent_admin.php?do=delete_reward&rewardid=$reward[rewardid]\">Delete</a>";
        
                print_cells_row($cell);
                unset($cell);
            }
            
    echo '<tr><td align="center" class="alt1" colspan="4"><a style="font-weight: bold;" href="incent_admin.php?do=add_reward">Add Reward</a></td></tr>';        
    print_table_footer(4, '', '', 0);
(Phrases are hard coded coz the hack is just for my own use, for now)


Also, thanks to Revan for his [How-To] Paginate your results for user pages.

Awsome TX....

5x stars


EDIT :
Im haveing problems with linking to pages..

The problem is, linking from pagenavs
and the one that lists my query is DO Find
and when i change the pagenav to fit the links to the other pages fail

Code:
$pagenav .= " <a href=\"sh2.php?$session[sessionurl]do=Find&amp;page=$thispage\" class=\"normal\">$thispage</a> ";


and find is the one printing results, and works fine, only shows the ammount i
set it for, howewer when clicking additional pages, it goes blank just as if it cant
located the requested destination..

any suggestions ? Im confused where the link goes, i can see it goes to do=find but the rest page=X
heh nope.
