無法將數據存儲到數據庫中

Question

我正在處理一個應用程序，該應用程序通過PHP API將用戶輸入存儲到數據庫表中，但我從PHP代碼獲得了一條錯誤消息給LogCat。任何建議將不勝感激。

D/Create Response(284): {"message":"Required field(s) is missing","success":0} 

PHP API

<?php 
// array for JSON response 
$response = array(); 

// check for the fields 
if (isset($_POST['title']) && isset($_POST['request_date']) && isset($_POST['reqEndDate']) && isset($_POST['reason']) && isset($_POST['requestor']) && isset($_POST['status']) && isset($_POST['submitDate']) && isset($_POST['explanation']) && isset($_POST['hours']) && isset($_POST['id'])) { 

    $title = $_POST["request_title"]; 
    $date = $_POST["request_date"]; 
    $eDate = $_POST["reqEndDate"]; 
    $reason = $_POST["reason"]; 
    $requestor = $_POST["requestor"]; 
    $status = $_POST["status"]; 
    $dateSubmitted = $_POST["submitDate"]; 
    $explanation = $_POST["explanation"]; 
    $numhours = $_POST["hours"]; 
    $id = $_POST['id']; 


    // mysql inserting a new row 
    $result = mysql_query("INSERT INTO requests(request_title, request_date, reqEndDate, reason, requestor, status, submitDate, explanation, hours, empid) 
          VALUES('$title', '$date', '$eDate', '$reason', '$requestor', '$status', '$dateSubmitted', '$explanation', '$numhours', '$id')"); 


?>

只是計算您的數據庫列：似乎是他們中的12。你只能插入到11中，並且在消除之後，它看起來像你正在離開「主動」，除非它具有默認值或可以爲空，否則會拋出「必填字段缺失「你嘗試插入數據庫時​​遇到的錯誤。
