我有一些PHP代码，从数据库中提取数据，并将其放置到三列布局，如下所示:
第一栏第二栏第三栏
现在可以工作了，唯一的问题是，while循环继续进行，它一遍又一遍地重复相同的数据。如果我在数据库中只有一个条目，那么这将重复三次，最后得到一列数据。如下所示:
http://www.gulfwarmemorial.co.uk/events.php如果我有三个条目，那么行是重复的。我试了各种方法，但似乎都不起作用。
$tableName="fundraising_event";
$targetpage = "events.php";
$limit = 6;
$query = "SELECT COUNT(*) as num FROM $tableName";
$total_pages = mysql_fetch_array(mysql_query($query));
$total_pages = $total_pages[num];
$stages = 3;
$page = mysql_escape_string($_GET['page']);
if($page){
$start = ($page - 1) * $limit;
}else{
$start = 0;
}
// Get page data
$query1 = "SELECT *, SUBSTRING(event_details,1,200) AS event_details_short FROM $tableName LIMIT $start, $limit";
$result = mysql_query($query1);
// Initial page num setup
if ($page == 0){$page = 1;}
$prev = $page - 1;
$next = $page + 1;
$lastpage = ceil($total_pages/$limit);
$LastPagem1 = $lastpage - 1;
$paginate = '';
if($lastpage > 1)
{
$paginate .= "<div class='paginate'>";
// Previous
if ($page > 1){
$paginate.= "<a href='$targetpage?page=$prev'>previous</a>";

问题是，反过来，您需要用数据库中的当前事件填充一个事件列。因此，您需要为下一行添加一个选择器来填充下一个事件列。
您可以选择依次填充每个列，这稍微复杂一些。或者水平填充这些列。这段代码试图做到的。
这是所有未经测试的代码，但希望显示所需的逻辑。
