mysql將assoc提取到列中

Question

我已經使用do多年了，但一直都是逐行輸出

我想做的是輸出到4列-

我已經嘗試了其他各種問題的一些方法，但似乎無法將其鎖定。

在此示例中，我在所有四列中都獲得了相同的信息-

不太了解如何讓單個行計數器為每一列單擊-

請原諒任何格式粗俗性-對此界面不太確定

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>

我假設這就是您要執行的操作，即跨頁行中的四個項目，對於從數據庫中讀取的每一行都重復執行。

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); 
?>

當您使用現代布局工具時，還應至少將width="200"更改為嵌入式樣式，即style="width:200px"

您還使用了不推薦使用的mysql_擴展名，並且幾個月后將在PHP7中將其完全刪除。 您應該將其移至mysqli_或PDO以mysqli_有關此文檔的幫助 。

根據我的評論，看看它是否適合您。

<div class='row'>
<?php $i=1; for ($x=0;$x<count($row_products);$x++) { ?>  
    <div class="col-md-3">
        <img src="<?php echo $row_products['productURL']; ?>" width="200"><br>
        <span class="dM"><?php echo $row_products['productName']; ?></span> <br>
        <span class="dN"><?php echo $row_products['price']; ?></span><br>
            <p><a class="btn btn-default" href="#" role="button">add to cart &raquo;</a></p>
    </div>
<?php if ($i == 4) {
        echo "</div><div class='row'>";
        $i = 1;
    } else {
        $i++;
    }
}
?>
</div>
