我有两个小问题;
1。我想在此代码中添加上一个/下一个按钮 2。我希望它只显示前一个和下一个之间的最多10个链接。因此,如果我有50个数字/链接,它将只显示10个,而不是页面上的50个链接。
我在clo上搜索了
代码有效,只需要两个选项。 有人可以帮我吗?谢谢!
<?php
include 'includes/connection.php';
$per_page = 8;
$pages_query = mysql_query("SELECT COUNT(`id`) FROM `products`");
$pages = ceil(mysql_result($pages_query, 0) / $per_page);
$page = (isset($_GET['page'])) ? (int)$_GET['page'] : 1;
$start = ($page - 1) * $per_page;
$query = mysql_query("SELECT `name` FROM `products` LIMIT $start, $per_page");
while ($query_row = mysql_fetch_assoc($query)) {
echo '<p>', $query_row['name'] ,'</p>';
}
if ($pages >= 1 && $page <= $pages) {
for ($x=1; $x<=$pages; $x++) {
//echo $x, ' ';
echo ($x == $page) ? '<strong><a href="?page='.$x.'">'.$x.'</a></strong> ' : '<a href="?page='.$x.'">'.$x.'</a> ';
}
}else{
header("location:index.php?page=1");
}
?>

首先,你应该,只是为了良好的做法,放一个“退出”;在header()之后调用。它在这个特定的脚本中没有什么区别,但请记住,在重定向之前,将执行标题(“Location:...”)调用之后的任何代码。
现在回答您的问题,试试这个(更新:此代码已经过测试并且有效。)

}
echo implode('', $html);
还要注意最终?&gt;
,在PHP代码之后没有HTML代码的PHP文件中不需要这样做。
