Question

我正在开发一个应用程序，它通过PHP API将用户输入存储到数据库表中，但是我收到了从PHP代码到LogCat的错误消息。任何建议都将不胜感激。

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')");


?>

只计算您的数据库列：似乎有12个。你只是插入到11中，并且在消除过程之后，看起来你正在遗漏“活动”，除非它有一个默认值或者可以为null，否则会抛出“必填字段” “尝试插入数据库时遇到的错误。
