Question

我会尝试解释我的问题，但我的英语不好，所以我希望你能理解我。

目前，当我在管理页面中添加产品时，它们会在一行中显示在另一个旁边，例如，如果我添加10个产品，我必须向右滚动页面才能看到它们。

现在我想在5个产品的网格中显示它们。因此，当我添加产品时，其中五个显示在一行中，然后第六个产品显示在第一个产品下面，依此类推。我真的非常需要这个，所以每一个帮助都会很有用，谢谢你的每一个答案。

这是代码

<?php 
include "storescripts/connect_to_mysql.php"; 
$sql = mysql_query("SELECT * FROM products ORDER BY date_added DESC LIMIT 10");
$productCount = mysql_num_rows($sql); // count the output amount
if ($productCount > 0) {
echo"<table width='100%' border='0' cellspacing='5' cellpadding='6'>";
   echo "<tr>";
while($row = mysql_fetch_array($sql)){ 
        $id = $row["id"];
$product_name = $row["product_name"];
$price = $row["price"];
$date_added = strftime("%b %d, %Y", strtotime($row["date_added"]));

    $count = 0;   
    if($count == 5) {
            $count = 0;                     
            echo "</tr> <tr>";       
    }
     echo "<td width='17%' valign='top'><a href='product.php?id=" . $id . "'><img              `enter code here`style='border:#666 1px solid;' src='inventory_images/" . $id . ".jpg' `enter code here`alt='" . $product_name . "' width='77' height='102' border='1' />     </a>`enter code here`</td>";
       echo "<td width='83%' valign='top'>" . $product_name . "<br />
       $" . $price . "<br />";
       echo "<a href='product.php?id=" . $id . "'>View Product Details</a></td>"; 

}

}else {
echo "We have no products listed in our store yet";
}

   echo"</tr>";
 echo"</table>";
mysql_close();
?>

Answer 1

声明$count=1;一边while循环

像这样使用

if($count % 5==0) {                     
        echo "</tr> <tr>";       
}

并且在while循环结束之前增加$count++

Answer 2

   if ($productCount > 0) {
echo"<table width='100%' border='0' cellspacing='5' cellpadding='6'>";

    $count = 0;
while($row = mysql_fetch_array($sql)){
            echo "<tr>";
    $id = $row["id"];
    $product_name = $row["product_name"];
    $price = $row["price"];
    $date_added = strftime("%b %d, %Y", strtotime($row["date_added"]));
    echo "<td width='17%' valign='top'><a href='product.php?id=" . $id . "'><img style='border:#666 1px solid;' src='inventory_images/" . $id . ".jpg' `enter code here`alt='" . $product_name . "' width='77' height='102' border='1' />     </a>`enter code here`</td>";
    echo "<td width='83%' valign='top'>" . $product_name . "<br />
   $" . $price . "<br />";
    echo "<a href='product.php?id=" . $id . "'>View Product Details</a></td>";
    if($count%5==0) {
        echo "</tr> <tr>";
    }
        echo "</tr> ";
}
    $count++;
   }
