PHP電子郵件購物車沒有被填充循環

即時通訊試圖做的是從網站生成一個購物車，並讓它通過電子郵件發送。當我運行我的代碼時，該函數在頁面上運行，並不通過電子郵件發送，但它顯示正確。我不能得到我的函數的輸出存儲到一個將在電子郵件中工作的變量。這裏是我的代碼有...PHP電子郵件購物車沒有被填充循環

在函數emailcartview中，您需要生成字符串而不是echo語句，並且在函數結束時您應該返回該字符串。

檢查下面的代碼：

function emailcartview() { 
$total=0; 
$totalvalue=0; 
$str = ''; 
foreach($_SESSION as $name => $value) { 
    if ($value>0){ 
     if (substr($name, 0, 5)=='cart_'){ 
      $id = substr($name, 5, (strlen($name)-5)); 
      $get = mysql_query('SELECT id, name, cost, item_number FROM mydbname WHERE id='.mysql_real_escape_string((int)$id)); 


      $cart = array(); 
      while ($get_row = mysql_fetch_assoc($get)) { 
       $cart[] = array(
       'hsid' => $get_row['id'], 
       'cost' => $get_row['cost'], 
      $cost = $get_row['cost'], 
       'itemno' => $get_row['item_number'], 
       'name' => $get_row['name'], 
       'value' => $value, 
       $sub = $value*$cost, 
       $total += $sub, 
       $totalvalue = $value, 
       'realsub' => number_format($sub, 2), 
       ); 

       } 
       foreach($cart as $index => $record){ 
        global $emailcart; 
        $str. = "Item: {$record['itemno']} - {$record['name']} | Qty: {$record['value']} | Cost: {$record['cost']} x {$record['value']} = {$record['realsub']} <br>"; 

      } 

     } 

    } 


} 
$str. = "Total : $".number_format($total, 2); 
return $str; 
} 


$emailSubject = 'Invoice Submission'; 
$webMaster = '[email protected]'; 


$companyName = $_POST['companyname']; 
$contactName = $_POST['contactname']; 
$contactEmail = $_POST['contactemail']; 
$teleNumber = $_POST['telenumber']; 
$billAddr = $_POST['billaddr']; 
$shipAddr = $_POST['shipaddr']; 
$neededBy = $_POST['neededby']; 
$cartprint .= emailcartview(); 

$body = " 
<br><hr><br> 
Company Name: $companyName <br> 
Contact Name: $contactName <br> 
Contact Email: $contactEmail <br> 
Telephone Number: $teleNumber <br>

Shipping Address: $shipAddr <br> 
Date Needed: $neededBy <br> <br> 
<br><hr><br> 
".emailcartview(); 

$headers = "From: [email protected]\r\n"; 
$headers .= "Content-type: text/html\r\n"; 
$success = mail($webMaster, $emailSubject, $body, $headers); 

?>

當我嘗試返回行，只發出了第一項.....據我瞭解它結束與返回指令循環以某種方式......你能解釋我可以怎麼做嗎？ – user1834995

添加代碼。現在檢查。 – VibhaJ

這工作幾乎完美！我現在唯一的問題是我不能讓總回報，我只能使用一個回報？它是你在回報之上註釋掉的代碼。 – user1834995
