我想在下面的脚本中添加分页，该脚本搜索数据库并将文件夹中的图像输出到行和列中。但我希望输出在页面中，而不是在同一页面上。我该怎么办？
<?php
echo '<table border="0" cellpadding="15" cellspacing="15">';
$getImages = mysql_query("SELECT * FROM yaamembers");
if(!$getImages)
die("Cannot execute query. " . mysql_error());
$countRows = mysql_num_rows($getImages);
$i = 0;
if ($countRows > 0)
{
while ($row_rsYaamembers = mysql_fetch_assoc($getImages))
{
if ($i % 3 == 0) echo ($i > 0? '</tr>' : '') . '<tr>';
echo '<td valign="top"><a target="_blank" href="yimagelarge.php?yaaid=' . $row_rsYaamembers['yaaID'] . '"><img src="/home/youngatart/yaamembers/'.$row_rsYaamembers['photo'].'" border="0" width="120" /></td>';
if ($i == $countRows - 1)
echo '</tr>';
$i++;
}
}
echo '</table>';
?>
我修改了代码，得到了三行三列图像，页面上的最后一行填充了一个图像。对于分页链接生成的所有页面，这是相同的。它应该在进入下一页之前均匀填满。我能做错什么？
以下修改后的代码：
<?Php
$getImages = mysql_query("SELECT * FROM yaamembers");
if(!$getImages)
die("Cannot execute query. " . mysql_error());
$output = "";
$getImages = get_images($start,$limit);
if ($getImages && mysql_num_rows($getImages) > 0)
{
/* Pagination section2 */
$getAllImages = get_images();
$total_items = mysql_num_rows($getAllImages);
$paginate = paginate($targetpage,$total_items,$limit,$pagenum);
$paginate = trim($paginate);
/* Pagination section2 End */
echo '<table border="0" cellpadding="15" cellspacing="15">';
$countRows = mysql_num_rows($getImages);
$i = 0;
if ($countRows > 0)
{
while ($row_rsYaamembers = mysql_fetch_assoc($getImages))
{
if ($i % 3 == 0) echo ($i > 0) . '<tr>';
echo '<td valign="top"><a target="_blank" href="yimagelarge.php?yaaid=' . $row_rsYaamembers['yaaID'] . '"><img src="http://localhost/youngatart/yaamembers/'.$row_rsYaamembers['photo'].'" border="0" width="120" /></a><div id="text2"><div class="clear_4"></div><div align="center" id="text2"><a target="_blank" href="yimagelarge.php?yaaid=' . $row_rsYaamembers['yaaID'] . '"><div align="center" id="text2"> '.$row_rsYaamembers['school'].'</a></div><div class="clear_4"></div><div align="center" id="text2"><a target="_blank" href="yimagelarge.php?yaaid=' . $row_rsYaamembers['yaaID'] . '"> '.$row_rsYaamembers['year'].'</a></div></div></td>';
if ($i == $countRows - 1)
echo '</tr>';
$i++;
}
}
echo '</table>';
$output .= $paginate;
}
echo $output;
?>
答案 0 :(得分：0)
我建议您对脚本进行简单的更改，以使我的解释变得舒适（因为我不是一个优秀的程序员！:)）。另外，我已经创建了一些可以使用的函数。
建议的更改
get_images作为一项功能function get_images($start=0,$limit=0)
{
mysql_connect("host","user","pass")or die("Cannot connect DB");
mysql_select_db("db_name")or die("DB does not exist");
$sql = "SELECT * FROM yaamembers";
if($start!=0 || $limit!=0)
{
$sql .= " LIMIT ". $start .", ". $limit;
}
$sql .= ";";
$data = mysql_query($sql);
mysql_close();
return $data;
}
/* Pagination section1 */
$pagenum = 1;
$limit = 10; /* Items per page*/
$start = 0;
