Question

此代码完美无缺。但我无法获得该表的最后一行。例如：我的表有9行，但这只有8行，缺少1行。当我使用ASC或DESC时，缺少的行是最后一行。这是我的代码.. 抱歉我的英语不好。 谢谢！

的index.php

<?php
$db_username = 'root';
$db_password = '';
$db_name = 'ad_man';
$db_host = 'localhost';
$item_per_page = 2;
$connecDB = mysqli_connect($db_host, $db_username, $db_password,$db_name)or die('could not connect to database');
    if($check_ad = mysqli_query($connecDB,"SELECT ad_uid FROM fullbanner WHERE ad_uid='501'")){
        $countr=mysqli_num_rows($check_ad);
    if($countr>=1){

    $pages = $countr/$item_per_page;


    //create pagination
    if($pages > 1)
    {
        $pagination = '';
        $pagination .= '<ul class="paginate">';
        for($i = 1; $i<$pages; $i++)
        {
            $pagination .= '<li><a href="#" class="paginate_click" id="'.$i.'-page">'.$i.'</a></li>';
        }
        $pagination .= '</ul>';
    }

    }else {$pagination="<ul class='paginate'>Empty ADs</ul>";}}else {$pagination="Empty ADs";}//mama

Answer 1

检查页码是否等于0，如果不简单地将$ position除以2

//get current starting point of records
if ($position === 0) $position = $position;
else $position = ($position/2)
