Question

我正在尝试通过电子邮件发送数组（购物车）中的结果，但是当我发送电子邮件时，它只是电子邮件中显示的第一个名称，价格和数量，而不是任何其他名称，价格或数量＆＃39;第我假设我的循环有问题，但不确定在哪里。提前谢谢了。结果放在comma_separated变量

中

$result= mysqli_query($conn, "SELECT * FROM testtable  ");

// save product list as array

if (mysqli_num_rows($result) > 0) {

while($row = mysqli_fetch_object($result)) 
{
$sku = $row->ProductSKU;
$productInfo[$sku] = array();
$productInfo[$sku]['Name'] = $row->Name;
$productInfo[$sku]['Price'] = $row->Price;
$productInfo[$sku]['QTY'] = $row->QTY;
}
} else {
die ("ERROR");
}

$i=0;
$total=0;
// print the currently selected items
foreach ($_SESSION['cart'] as $sku => $quantity) {


$subtotal = $quantity * $productInfo[$sku]['Price'];
$total += $subtotal;
$array = array("Product:".$productInfo[$sku]['Name'],
"Units @".$productInfo[$sku]['Price'] ,
"Total:".number_format($subtotal, 2));
$comma_separated = implode("\n", $array);
}

Answer 1

您应该更改以下代码：

// print the currently selected items
foreach ($_SESSION['cart'] as $sku => $quantity) {


$subtotal = $quantity * $productInfo[$sku]['Price'];
$total += $subtotal;
$array = array("Product:".$productInfo[$sku]['Name'],
"Units @".$productInfo[$sku]['Price'] ,
"Total:".number_format($subtotal, 2));
$comma_separated = implode("\n", $array);
}

成：

// print the currently selected items

$comma_separated = array();

foreach ($_SESSION['cart'] as $sku => $quantity) {


$subtotal = $quantity * $productInfo[$sku]['Price'];
$total += $subtotal;
$array = array("Product:".$productInfo[$sku]['Name'],
"Units @".$productInfo[$sku]['Price'] ,
"Total:".number_format($subtotal, 2));

 $comma_separated[] = implode(', ',$array);
}
$comma_separated = implode("\n", $comma_separated);

之前你已经创建了产品数组，使用新行破坏了它，但最后你还没有将这个数组保存在任何其他变量中，所以每次运行foreach循环时你都会再次初始化$comma_separated变量，所以之前的价值不在那里。

现在您应该将$comma_separated附加到邮件内容，例如：

$mail_content .= $comma_separated;
