Php Mysql结果没有正确对齐

我有一个引导购物车，我正试图添加到我的网站，问题是表单的第一行非常完美（四对一行），但是第二行分割其结果，一行两个，另一行两个

我可以得到的结果显示每行两个完美没有任何错误。但我似乎无法得到四列的正确结果

可在此处找到该网站的链接

网页中的HTML和PHP

<section class="products" data-image="">

<?php
//
// Show Product Grid 
//
if (isset($_GET['category'])) {
    $category = $_GET['category'];
} else {
    $category = 1;
} // list category from table bsc_category
$shoppingcart_vertical = 0; // if the is vertical shoppingcart_vertical=1 / is top or bottom are horitzontal -> shoppingcart_vertical=0
$_SESSION['LastProductPage'] = $_SERVER["REQUEST_URI"]; // take the name of this page for return
include "BootstrapShoppingCart/products_grid.php";  // list products 
//
// Show Product Grid 
//
?>                   

</section>

以下代码是形成结果的部分，是产品网格页面内容的一部分。我遗漏了sooe代码，但这只是查询，不认为它有任何关系

<div class=".col-md-3" data-id="<?php echo $thisproduct[0]    ['id_product']; ?>" data-type="<?php

    echo 'select'; // are selection/type? 
}
?>" data-quantity="1">
    <div class="thumbnail">

                $price = new getprice($rs['id'], 0); // first its id->product second id->type
                $price_array = $price->get(); // getting price [0] = no offer price [1]= offer price

                if (count($thisproduct)==1) { // its only 1 product or ... have types ?
                    if ($thisproduct[0]['price'] > 0) { // have price ?

选择。。。

对于初学者来说，在HTML代码的第一行，您的class属性中似乎有一个额外的
