使用PHP在bootsrap中动态形成列

Question

i want to dynamically display content in 3 bootstrap colums.

<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)

while i fetch the query to mysql. Also i want object to sort in descending order from left to right (id = 51, id = 50, id = 42 (last digit in the object title is id)) I was able to do that, using row_number and row_number%3=0 row_number%3=1 and row_number%3=2 to display 3 columns, but i have to make 3 queries to the database along with 3 blocks of html(which is bad).

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

But, when i started to implement filters, it caused problems with displaying objects, because not every column had the object i wanted to display, but i had own query for every column. Problems with filters

What i want: Dynamically form 3 separate columns with content to use one MYSQL query. Waiting for your help! Example of 1 of 3 columns:

<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();

Answer 1

I think you are simply trying to iterate over your results, generate 3 columns of output, and then also apply filters, maybe through Javascript, which hide some of your elements. The simplest way I know to do that is as follows:

<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

I don't think it's possible to do, what i wanted to do, instead i found much easier way to display content: just unite 3 columns in one and put all data there. Ye, it has problems when you open the spoiler, but i think i'll deal with it. Thank you for all your answers.
