php - mysql 将关联提取到列中

Question

我已经使用 do while 多年了，但总是逐行输出

我想要做的是输出到 4 列 -

我已经从其他各种问题中尝试了几件事，但似乎无法锁定它。

在此示例中 我在所有四列中获得相同的信息 -

不太了解如何让单独的行计数器单击每列 -

请原谅任何格式的粗俗 - 不太确定这个界面

mysql_select_db($database_products, $products);
        $query_products = "SELECT productURL, productName, price FROM products WHERE      productName LIKE '%earring%' AND merchantId = 37638 ORDER BY id ASC";
        $products = mysql_query($query_products, $products) or die(mysql_error());
        $row_products = mysql_fetch_assoc($products);
        $totalRows_products = mysql_num_rows($products);


    <?php do { ?>  

            <div class="col-md-3">

              <img src="<?php echo $row_products['productURL']; ?>" width="200"><br>

我假设这就是您所追求的，即页面上行中的四个项目，对从数据库读取的每一行重复。

mysql_select_db($database_products, $products);
$query_products = "SELECT productURL, productName, price 
                   FROM products 
                   WHERE productName LIKE '%earring%' 
                     AND merchantId = 37638 
                   ORDER BY id ASC";
$products = mysql_query($query_products, $products) 
             or die(mysql_error());

$totalRows_products = mysql_num_rows($products);


while ($row_products = mysql_fetch_assoc($products) ) : 
?>  
    <div class="col-md-3">
        <img src="<?php echo $row_products['productURL']; ?>" width="200">
    </div>

    <div class="col-md-3">
        <span class="dM"><?php echo $row_products['productName'];?></span>
    </div>

    <div class="col-md-3">
        <span class="dN">$<?php echo $row_products['price']; ?></span>
    </div>

    <div class="col-md-3">
        <p>
         <a class="btn btn-default" href="<?php echo $row_products['productLink']; ?>" role="button">add to cart &raquo;</a>
        </p>
    </div>

<?php 
endwhile;  

mysql_free_result($products); 
?>

当您使用现代布局工具时，您还应该将 width="200" 至少更改为内联样式，即 style="width:200px"

You are also using the mysql_ extension which is deprecated and to be totally removed in PHP7 out in a few months. You should look to move this to mysqli_ or PDO see this document for a bit of help on that.
