Question

我知道有一种更简单的方法可以做到这一点。我想要做的是按编号对字段进行分组，并使用isset来测试$ _POST ['item＃']值是否为空。如果该项目＃不为空，我想发送相应的颜色，数量和价格。如果提交了多个项目，我想发送倍数。

以下是我的帖子变量：

$item1 = $_POST['item1'];
$color1 = $_POST['color1'];
$quantity1 = $_POST['quantity1'];
$price1 = $_POST['price1'];

$item2 = $_POST['item2'];
$color2 = $_POST['color2'];
$quantity2 = $_POST['quantity2'];
$price2 = $_POST['price2'];

$item3 = $_POST['item3'];
$color3 = $_POST['color3'];
$quantity3 = $_POST['quantity3'];
$price3 = $_POST['price3'];

$item4 = $_POST['item4'];
$color4 = $_POST['color4'];
$quantity4 = $_POST['quantity4'];
$price4 = $_POST['price4'];

$item5 = $_POST['item5'];
$color5 = $_POST['color5'];
$quantity5 = $_POST['quantity5'];
$price5 = $_POST['price5'];

$item6 = $_POST['item6'];
$color6 = $_POST['color6'];
$quantity6 = $_POST['quantity6'];
$price6 = $_POST['price6'];

$item7 = $_POST['item7'];
$color7 = $_POST['color7'];
$quantity7 = $_POST['quantity7'];
$price7 = $_POST['price7'];

$item8 = $_POST['item8'];
$color8 = $_POST['color8'];
$quantity8 = $_POST['quantity8'];
$price8 = $_POST['price8'];


I'm using isset to test if $_POST[] values are empty:

if( isset($_POST['item1']) )
{
    $message = 'Item: '.$item1." \nColor: ".$color1." \nQuantity: ".$quantity1." \nPrice: ".$price1;

}

if( isset($_POST['item2']) )
{
    $message = 'Item: '.$item2." \nColor: ".$color2." \nQuantity: ".$quantity2." \nPrice: ".$price2;
}

if( isset($_POST['item3']) )
{
    $message = 'Item: '.$item3." \nColor: ".$color3." \nQuantity: ".$quantity3." \nPrice: ".$price3;
}

if( isset($_POST['item4']) )
{
    $message = 'Item: '.$item4." \nColor: ".$color4." \nQuantity: ".$quantity4." \nPrice: ".$price4;
}

if( isset($_POST['item5']) )
{
    $message = 'Item: '.$item5." \nColor: ".$color5." \nQuantity: ".$quantity5." \nPrice: ".$price5;
}
if( isset($_POST['item6']) )
{
    $message = 'Item: '.$item6." \nColor: ".$color6." \nQuantity: ".$quantity6." \nPrice: ".$price6;
}
if( isset($_POST['item7']) )
{
    $message = 'Item: '.$item7." \nColor: ".$color6." \nQuantity: ".$quantity7." \nPrice: ".$price7;
}
if( isset($_POST['item7']) )
{
    $message = 'Item: '.$item8." \nColor: ".$color7." \nQuantity: ".$quantity8." \nPrice: ".$price8;
}

Answer 1

$items = $_POST['item'];

for ($i = 0; $i < count($items); $i++) {
    if ($items[$i])){  //not necessarily the best way to check if it has a value
        //do what you want with $items[$i], $color[$i], $quantity[$i], and $price[$]
    }
}

对于HTML表单输入，请使用：

<input type="text" name="item[]" />

Answer 2

这是请求的HTML。我只是在学习，所以我确信有更有效的方法来命名输入。我尝试对item-color-quantity-price进行分组，以便在通过电子邮件发送表单时，相关数据位于每个项目的段落或表格中。

<td align="center"><p><span>Item Name</span><br><input id="item1" type="text" name="item1"></p></td>
<td align="center"><p><span>Color</span><br><input id="color1" type="text" name="color1"></td>
<td align="center"><p><span>Quantity</span><br><input id="quantity1" type="text" name="quantity1"></td>
<td align="center"><p><span>Wholesale Price</span><br><input id="price1" type="text" name="price1"></td>
</tr>
<tr>
<td align="center"><p><input id="item2"  type="text" name="item2"></p></td>
<td align="center"><p><input id="color2" type="text" name="color2"></p></td>
<td align="center"><p><input  id="quantity2" type="text" name="quantity2"></p></td>
<td align="center"><p><input id="price2" type="text" name="price2"></p></td>
</tr>
<tr>
<td align="center"><p><input id="item3" type="text" name="item3"></p></td>

<tr>
<td align="center"><p><input id="item4" type="text" name="item4"></p></td>

<td align="center"><p><input id="price4" type="text" name="price4"></p></td>

<tr>
<td align="center"><p><input id="item5" type="text" name="item5"></p></td>

我将所有输入名称转换为数组，并且我有工作循环。但是，我需要格式化foreach以生成带表的HTML电子邮件。它在回显数据时工作得很好但是一旦我将其格式化为$ message消息，它只发送最后一个$ item。

以下是完美运行的foreach循环：

foreach ( $_POST['item'] as $items) {
    {
       echo '<table>';
        echo '<tr>';
        echo '  <td>', $items['name'], '</td>';
        echo '  <td>', $items['color'], '</td>';
        echo '  <td>', $items['size'], '</td>';
        echo '  <td>', $items['quantity'], '</td>';
        echo '  <td>', $items['price'], '</td>';
        echo '</tr>';
    }
    echo '</table>';
}

使用PHP邮件功能的HTMl电子邮件：

foreach（$ _POST ['item'] as $ items）{

$message = "
   <html>
   <body>
   <table>
   <tr>
    <th>Name</th>
    <th>Color</th>
    <th>Size</th>
    <th>Quantity</th>
    <th>Price</th>
    </tr>
    <tr>
      <td>" . $items['name'] . "</td>
      <td>" . $items['color'] . "</td>
      <td>" . $items['size'] . "</td>
      <td>" . $items['quantity'] . "</td>
      <td>" . $items['price'] . "</td>
    </tr>
    </table>
    </body>
    </html>
    ";
}
