php - 如何在标题标签中添加分页号

问题描述

这是分页代码它的作品很好的分页显示像这个url mywebsite.com/samplepage.php?page=1 等等..代码是

<?php
    include"config.php";


function pagination($query,$per_page=10,$page=1,$url='?'){   
    global $conn; 

    $query = "SELECT COUNT(*) as `num` FROM {$query}";
    $row = mysqli_fetch_array(mysqli_query($conn,$query));

    $total = $row['num'];
    $adjacents = "2"; 

    $prevlabel = "&lsaquo; Prev";
    $nextlabel = "Next &rsaquo;";
    $lastlabel = "Last &rsaquo;&rsaquo;";

    $page = ($page == 0 ? 1 : $page);  
    $start = ($page - 1) * $per_page;                               

    $prev = $page - 1;                          
    $next = $page + 1;

    $lastpage = ceil($total/$per_page);

    $lpm1 = $lastpage - 1; // //last page minus 1

    $pagination = "";

    if($lastpage > 1){   

        $pagination .= "<ul class='pagination'>";
        $pagination .= "<li class='page_info'>Page {$page} of {$lastpage}</li>";

        if ($page > 1) $pagination.= "<li><a href='{$url}page={$prev}'>{$prevlabel}</a></li>";



        if ($lastpage < 7 + ($adjacents * 2)){   

            for ($counter = 1; $counter <= $lastpage; $counter++){

                if ($counter == $page)
                    $pagination.= "<li><a class='current'>{$counter}</a></li>";
                else
                    $pagination.= "<li><a href='{$url}page={$counter}'>{$counter}</a></li>";                    

            }

        } elseif($lastpage > 5 + ($adjacents * 2)){

            if($page < 1 + ($adjacents * 2)) {

                for ($counter = 1; $counter < 4 + ($adjacents * 2); $counter++){

                    if ($counter == $page)
                        $pagination.= "<li><a class='current'>{$counter}</a></li>";
                    else
                        $pagination.= "<li><a href='{$url}page={$counter}'>{$counter}</a></li>";                    

                }

                $pagination.= "<li class='dot'>...</li>";
                $pagination.= "<li><a href='{$url}page={$lpm1}'>{$lpm1}</a></li>";
                $pagination.= "<li><a href='{$url}page={$lastpage}'>{$lastpage}</a></li>";  

            } elseif($lastpage - ($adjacents * 2) > $page && $page > ($adjacents * 2)) {

                $pagination.= "<li><a href='{$url}page=1'>1</a></li>";
                $pagination.= "<li><a href='{$url}page=2'>2</a></li>";
                $pagination.= "<li class='dot'>...</li>";

                for ($counter = $page - $adjacents; $counter <= $page + $adjacents; $counter++) {

                    if ($counter == $page)
                        $pagination.= "<li><a class='current'>{$counter}</a></li>";
                    else
                        $pagination.= "<li><a href='{$url}page={$counter}'>{$counter}</a></li>";                    
                }

                $pagination.= "<li class='dot'>..</li>";
                $pagination.= "<li><a href='{$url}page={$lpm1}'>{$lpm1}</a></li>";
                $pagination.= "<li><a href='{$url}page={$lastpage}'>{$lastpage}</a></li>";      
            } else {
                $pagination.= "<li><a href='{$url}page=1'>1</a></li>";
                $pagination.= "<li><a href='{$url}page=2'>2</a></li>";
                $pagination.= "<li class='dot'>..</li>";
                for ($counter = $lastpage - (2 + ($adjacents * 2)); $counter <= $lastpage; $counter++) {

                    if ($counter == $page)
                        $pagination.= "<li><a class='current'>{$counter}</a></li>";
                    else
                        $pagination.= "<li><a href='{$url}page={$counter}'>{$counter}</a></li>";                    

                }
            }
        }
        if ($page < $counter - 1) {

            $pagination.= "<li><a href='{$url}page={$next}'>{$nextlabel}</a></li>";
                $pagination.= "<li><a href='{$url}page=$lastpage'>{$lastlabel}</a></li>";
        }
        $pagination.= "</ul>";        
    }
    return $pagination;
}
?>

我想像这样在标题中添加页码..

详细信息 - 第 24 页或详细信息 - 第 24 页，共 200 页（总页数）

我可以更新这个分页代码吗？此代码显示来自数据库的全部数据，但如果我想从表中的单行显示分页。来自“关键字”行的表格..但我的主要问题是如何在标题中显示页码..提前谢谢

解决方案

要为您的网站添加标题，您需要<title></title>在 html 头中添加标签。

你可能会做类似的事情

<title>Page <?php echo $pagination ?> of <?php echo $total ?></title>

如果您想即时更改它，您可以使用 javascript (链接)

document.title = currentPage+" of "+total;
