在PHP中使用foreach循環 - wordpress

Question

我想從foreach循環中排除電子郵件代碼，此時電子郵件成功消息顯示3次。我試過不同的組合，但不能讓它只顯示一次...？

任何想法..？感謝

if (isset($_POST['submit'])) { 

    $posted = $_POST; 
    $options = array('option-1' => __('Procedure: Suture Skin Wounds', 'appthemes'), 
      'option-2' => __('Procedure: Cat castration', 'appthemes'), 
      'option-3' => __('Procedure: Cat spay', 'appthemes') 
    ); 

    foreach ($options as $option => $value) { 

     if ($posted[$option] == "selected") { 
      echo "<li class='error-list'>"; 
      echo "Please select an answer for:" . " " . $value . " > 
    " . '<a href="' . get_permalink(30) . '">Back to form</a>'; 
      echo "</li>"; 
     }// if == "selected" 
     else/* if(isset($_POST['submit'])) */ { 

      $adminemail = get_option('admin_email'); 

      $ToEmail = $adminemail; 
      $EmailSubject = 'Skills Assessment Form'; 
      $mailheader = "From Leapfrog"; 
      $mailheader .= "Reply-To: " . $_POST["email"] . "\r\n"; 
      $mailheader .= "Content-type: text/html; charset=iso-8859-1\r\n"; 
      $MESSAGE_BODY = "Form:Small Animal\n"; 
      $MESSAGE_BODY = "Name: " . $_POST["canname"] . "\n\n"; 
      $MESSAGE_BODY .= "\n\n" . "Procedure: " . "Suture Skin Wounds: " . $_POST["option-1"]; 
      $MESSAGE_BODY .= "\n\n" . "Procedure: " . "Cat castration: " . $_POST["option-2"]; 
      $MESSAGE_BODY .= "\n\n" . "Procedure: " . "Cat spay: " . $_POST["option-3"]; 

      mail($ToEmail, $EmailSubject, $MESSAGE_BODY, $mailheader) or die("Failure"); 
      echo "Your skills assessment form has been Sent:" . " " . 
      '<a href="' . get_permalink(13) . '">Back to your Dashboard</a>'; 
      //echo '<a href="'.get_permalink(13).'">Dashboard</a>'; 
     }//else         
    }//foreach loop;  
}//if isset

你正在做foreach循環內的一切：顯示錯誤，郵件消息並顯示成功消息。

您需要將循環中的所有內容全部移出，例如在循環之前設置一個空的$errors數組並將所有錯誤消息添加到該數組。

然後，在循環之後，您可以檢查$errors數組是否仍爲空，併發送郵件並顯示您的成功消息。如果不是，則顯示所有錯誤。
