[1]为查询结果建立向后/向前按钮
    来源: 互联网  发布时间: 2013-11-30
最近在Support Forums上有很多问题都是关于如何为一个搜索结果制作象"向后 1 2 3 4 5 向前"样子 的链接。我希望下面的脚本可以帮助你,在你的搜索结果页面中加入这种功能。这个例子是专为MySQL所写 的,但是对于其它的SQL引擎也可以很容易地适应。

  因为每种应用都是不同的,这样我使用了一些通用的语句进行MySQL查询处理。TABLE名应该替换成你的 实际表名。YOUR CONDITIONAL HERE应该替换成你的where 条件,并且WHATEVER应该替换成你希望对结果进 行排序的字段(如果你的应用需要降序排列,不要忘记加上DESC)。

<?php

$limit=20; // 返回的行
$numresults=mysql_query("select * from TABLE where YOUR CONDITIONAL HERE order by WHATEVER");
$numrows=mysql_num_rows($numresults);

// 接着判断是否offset已经传给脚本了,如果没有设为0
if (empty($offset)) {
    $offset=0;
}

// 取结果
$result=mysql_query("select id,name,phone ".
    "from TABLE where YOUR CONDITIONAL HERE ".
    "order by WHATEVER limit $offset,$limit");

// 现在可以显示返回结果了
while ($data=mysql_fetch_array($result)) {
    // 在此处包含如你所愿的显示结果代码
}

// 接着我们需要生成其它结果的链接

if ($offset==1) { // 如果offset为0,则忽略PREV链接
    $prevoffset=$offset-20;
    print "<a href="/blog_article/$PHP_SELF/offset/$prevoffset.html">PREV</a>   n";
}

// 计算需要链接的页面数
$pages=intval($numrows/$limit);

// 如果除后没有余数,$pages 现在包含需要页面的整数值
if ($numrows%$limit) {
    // 如果有余数那么增加一页
    $pages++;
}

for ($i=1;$i<=$pages;$i++) { // 循环
    $newoffset=$limit*($i-1);
    print "<a href="/blog_article/$PHP_SELF/offset/$newoffset.html">$i</a>   n";
}

// 检查是否为最后一页
if (!(($offset/$limit)==$pages) && $pages!=1) {
    // 如果不是下一页,则给出向后链接
    $newoffset=$offset+$limit;
    print "<a href="/blog_article/$PHP_SELF/offset/$newoffset.html">NEXT</a><p>n";
}

?>  

  这些对你来说可能有些用。当然,你可能想要使HTML的输出更干净一些...  

  而且,请注意在$PHP_SELF后的链接只包含了$offset。如果你需要为查询的where条件传递参数的话, 你也需也需要把这些补在上面。
