Php“预览”和“下一步”

Question

I have a code what generated a list for number of pages, but I want to replace them with two buttons “preview” and “next”

Code is:

$results = mysqli_query($connecDB,"SELECT COUNT(*) FROM list");
$get_total_rows = mysqli_fetch_array($results); //total records

//break total records into pages
$pages = ceil($get_total_rows[0]/$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>';
}

You'll need a var to know the current page, like:

$page = ($_GET['page']) ? (int)$_GET['page'] : 1;

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