Question

我想在3个bootstrap colums中动态显示内容。

<div class="col-xs-12 col-sm-6 col-md-6 col-lg-4">
<content> 
</div> <---- Problem (should be placed at the very end of the column, 
but the same code should also fill 2nd and 3rd columns)

我将查询提取到mysql。此外，我希望对象从左到右按降序排序（id = 51，id = 50，id = 42（对象标题中的最后一位数字是id））我能够做到这一点，使用row_number和row_number％3 = 0 row_number％3 = 1和row_number％3 = 2来显示3列，但我必须对数据库进行3次查询以及3个html块（这是坏）。

SELECT *
FROM (
    SELECT 
    @row_number:=@row_number + 1 AS rownum, id,title, description, ...etc
    FROM (
        SELECT @row_number:=0) r, flats ORDER BY id DESC) ranked WHERE rownum%3=1 ORDER BY id DESC

但是，当我开始实现过滤器时，它会导致显示对象出现问题，因为并非每列都有我想要显示的对象，但我对每一列都有自己的查询。 Problems with filters

我想要的：动态地形成3个单独的列，其内容使用一个MYSQL查询。等待你的帮助！ 3列中的1列示例：

<div class="col-xs-12 col-sm-6 col-md-6 col-lg-4">
<?php
  $zapros = $DB_con->prepare('SELECT *
FROM (
    SELECT 
    @row_number:=@row_number + 1 AS rownum, id,title, description,type, area,address, square, name, phone, email, price, avito, farpost
    FROM (
        SELECT @row_number:=0) r, flats ORDER BY id DESC) ranked WHERE rownum%3=1 ORDER BY id DESC');
  $zapros->execute();
  $rowsone=$zapros->rowCount();
if($zapros->rowCount() > 0)
  {$tmpCount = 1;

    $count=$zapros->rowCount();
    while($data=$zapros->fetch(PDO::FETCH_ASSOC))
    {
      extract($data);


       $number=$data['id'];
                                              $imagestm=$DB_con->prepare('SELECT file FROM flats_images WHERE post_id=:uid LIMIT 1');
                                              $imagestm->bindParam(':uid',$number);
                                              $imagestm->execute();
                                              $imgrow=$imagestm->fetch(PDO::FETCH_ASSOC);
                                              extract($imgrow);?>

<div class="well-lg well-smallborders">

                                              $imagestm2->execute();


for ($i = 1; $i <= $imagestm2->rowCount(); $i++) {
  $imgrow2=$imagestm2->fetch(PDO::FETCH_ASSOC);
                                              extract($imgrow2); ?>

<div class="col-xs-6 col-sm-6 col-md-4 col-lg-4">

我想要的实际结果：Actual result

Answer 1

我认为你只是试图迭代你的结果，生成3列输出，然后也可以通过Javascript来应用过滤器，这可能会隐藏你的一些元素。我知道这样做的最简单方法如下：

<div class="row">
    <div class="col-xs-12 col-sm-6 col-md-6 col-lg-4"></div>
    <div class="col-xs-12 col-sm-6 col-md-6 col-lg-4"></div>
    <div class="col-xs-12 col-sm-6 col-md-6 col-lg-4"></div>
    <div class="col-xs-12 col-sm-6 col-md-6 col-lg-4"></div>
    <div class="col-xs-12 col-sm-6 col-md-6 col-lg-4"></div>
    <div class="col-xs-12 col-sm-6 col-md-6 col-lg-4"></div>
    ... 
    <!-- Bootstrap can manage with only 1 .row -->
</div>

Answer 2

我不认为这是可能的，我想做什么，而是我找到了更简单的方式来显示内容：只需将3列合并为一个并将所有数据放在那里。是的，当你打开扰流板时它有问题，但我想我会处理它。谢谢你的所有答案。
