郵件表單發送成功消息，並檢查是否輸入！空

-2

因此，我正在做一個聯繫表單，當我們點擊提交時，它應該發送一封電子郵件給管理員，包括輸入。電子郵件功能已經正常工作，我缺少的是驗證，以檢查輸入字段是否爲空。我嘗試在輸入標籤中添加所需的屬性。它在本地主機上工作，但由於某種原因，不在服務器上。此外，它還需要彈出一條消息，確認您已提交表單。我在這裏使用了onclick函數。但我無法澄清它是否有效，因爲它只需在提交成功並且沒有空字段時彈出消息。郵件表單發送成功消息，並檢查是否輸入！空

這是我使用的代碼。連接已經建立。

有沒有不同的方式來做到這一點？

確實有辦法做到這一點，但它會涉及到你的一部分編碼。對於驗證，您不能隱式地信任客戶端驗證。您需要包含服務器端代碼來檢查值是否已提交。例如，您目前檢查'isset（$ _ POST ['submit']）'以查看錶單是否完全發佈。您可以執行類似的檢查以查看錶單中是否發佈了特定的數據元素，您可以檢查發佈的字符串的長度等。構建邏輯以執行檢查並相應地發送或不發送消息。 – David

下面是我用作我內部開發工具的一部分的驗證器。它是一個服務器端，也是一個更大框架的一部分，但它可以適合你。

       'error_list' => $errorList, 
       'error_msg' => $msg, 
      ); 
     } 
    } 

}

調用驗證這樣的：

$validator = new InputValidation(); 
     $val = $validator->validateInputs($data); 

     if (isset($val['error']) && $val['error'] == true) { 
      // do whatever 
      ); 
     }

驗證器也接受像

$的ExceptionList [ 'formField'， 'anotherFormFiled'] 使用其他可選參數，以免除驗證某些領域

$ alias pass as array（'formField'=>'Form Filed Caption'）用於顯示自定義的一些字段標題

$ filters作爲['email'=> array（'must'=>「@」）] 用於驗證輸入。例如電子郵件
