Question

我的客户网站在他的图库中超载图像。我想知道我是否可以得到一些建议，看看你们/女孩认为什么是处理我目前处境的最佳方式。

http://www.richsdockcompany.com/Gallery.php

此图库由php和mysql创建。我想设置12个图像的限制，然后它将切换到不同的页面，但它无法刷新页面，否则图库将重置。

当前的图库代码

<?php

include_once "header.php";
include($_SERVER['DOCUMENT_ROOT'] . "/connections/dbconnect.php");
$images = mysql_query("SELECT * FROM images");
while ($image=mysql_fetch_assoc($images))
?>

<div id="Wrap">
<div class="Titles"><h2 style="font-size:36px;">Rich's Dock Company Image Gallery</h2></div><br />
<hr />
<div id="PhotoBoxWrap">

我能想到的唯一一件事就是创建一个包含所有图像的滑块，或者使用带分页的ajax，这样就不会出现刷新问题。

我从未尝试过分页，所以请在这里轻松一下。

任何建议都将受到赞赏。

谢谢！

查看此示例代码，它以简单的方式处理分页。您可以为每个应该分页的列表重用函数getPagesNavi。它返回带有链接的html，以浏览页面。

如果你想用ajax加载页面，你需要自己做一些修改。这只是向您展示它如何运作的一个例子。

$page = intval($_GET['page']);
$myurl = 'index.php?action=list';

$db->select("select * from tablename");
$count_total = $db->getRecords();

$items_per_page = 10;
$start = $page * $items_per_page;
$limit = "limit $start, $items_per_page";

$db->select("select * from tablename $limit");

while($row = $db->fetchArray()) {
    // your output here...
}

echo getPageNavi($myurl,$page,$count_total,$items_per_page);


function getPagesNavi($link, $current_page, $count_total, $items_per_page, $number_of_visible_pagelinks_updown = 5, $page_varname = "page") {
    $result = "";
    if ($count_total <= 0) {
        return "";
    }
    $pages_float = $count_total / $items_per_page;
    $number_of_pages = ceil($pages_float) - 1;
    $start = $current_page - $number_of_visible_pagelinks_updown;
    $end = $current_page + $number_of_visible_pagelinks_updown;
    if ($end > $number_of_pages) {
        $dif = -$number_of_pages + $end;
        $end = $number_of_pages;
        $start = $start - $dif;
    }
    if ($start < 0) {
        $dif = -$start;
        $end = $end + $dif;
        $start = 0;
    }
    if ($end > $number_of_pages) {
        $end = $number_of_pages;
    }
    $back = $current_page - 1;
    $forward = $current_page + 1;
    if ($current_page > 0) {
        $result .= "
          <span class=\"pageItem\"><a href=\"$link&$page_varname=0\"><<</a></span>
          <span class=\"pageItem\"><a href=\"$link&$page_varname=$back\"><</a></span>";
    } else {
        $result .= "<span class=\"pageItem\"><<</span>";
        $result .= "<span class=\"pageItem\"><</span>";
    }
    for ($i = floor($start); $i <= floor($end); $i++) {
        $j = $i + 1;
        $class = "";
        if ($i == $current_page) {
            $class = " currentPageItem";
        } 
        $result.= "<span class=\"pageItem$class\"><a href=\"$link&$page_varname=$i\">$j</a></span>";
    }
    if ($current_page != $number_of_pages) {
        $result .= "<span class=\"pageItem\"><a href=\"$link&$page_varname=$forward\">></a></span>";
        $result .= "<span class=\"pageItem\"><a href=\"$link&$page_varname=$number_of_pages\">>></a></span>";
    } else {
        $result .= "<span class=\"pageItem\">></span>";
        $result .= "<span class=\"pageItem\">>></span>";
    }
    return $result;
}
