數據不會插入數據庫

[英]Data wont insert into Database

問題描述

我正在嘗試將表單中的數據插入到我的數據庫中，但它似乎不起作用。 我在插入查詢之后放了一個echo，所以我可以驗證數據是否已經插入，但它不會回顯我寫的內容。 我的查詢或我的PHP的任何部分有問題嗎？

我的PHP： 

<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "stat_system";

$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}

$fname = $lname = $mname = $contact = $age = $attain = $course = $school = $position = $exp = $ref = $batchtxt = $hiredate = $prevbpo = $remarks = $nho = $nonbpo = $holdAttain = $holdPos = "";
$error_flag = 0;                   


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

                $holdAttain = (isset($_POST['cmbAttain']));
                $holdPos = (isset($_POST['cmbPosition']));

                if (!empty($_POST['firstname'])) {
                    $fname = $_POST['firstname'];
                }

                if (!empty($_POST['lastname'])) {
                    $lname = $_POST['lastname'];
                }

                if (!empty($_POST['middlename'])) {
                    $mname = $_POST['middlename'];
                }

                if (!empty($_POST['contact'])) {
                    $contact = $_POST['contact'];
                }

                if (!empty($_POST['age'])) {
                    $age = $_POST['age'];
                }

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

                    $course = $_POST['course'];
                }

                if (isset($_POST['exp'])) {
                    $exp = $_POST['exp'];
                }

                if (!empty($_POST['remarks'])) {
                    $remarks = $_POST['remarks'];
                }

                    $batchtxt = $_POST['batchtxt'];
                }

                if (!empty($_POST['nho'])) {
                    $nho = $_POST['nho'];
                }

                if($error_flag == 0){
                    $sql = mysqli_query($conn,"INSERT INTO applicants (appID, appLastName, appFirstName, appMidleName, Age, appPhoneNumber, appBatch, appExperience, appRemarks, appPreviousBPO, appSchool, appCourse, appGraduate, appNonBPO, appPosition, appHireDate, appNHO, appReferrer)

4 個解決方案

解決方案1

使用$ _POST而不是$ _REQUEST ..

喜歡： 

$lname =  $_POST['lname'];

解決方案2

一目了然，你的NULL測試應該用&&而不是||分開 。 你有它的方式，它只檢查它們中的一個（任何）是否包含一個值。

解決方案3

您查詢時會出現一些錯誤，只需將其替換為 

$sql = "INSERT INTO applicants (appLastName, appFirstName, appMidleName, Age, appPhoneNumber, appBatch, appExperience, appRemarks, appPreviousBPO, appSchool, appCourse, appGraduate, appNonBpo, appPosition, appHireDate, appNHO, appReferrer) VALUES ('$lname','$fname','$mname',$age,'$con',$batch,'$exp','$rem','$prevbpo','$school','$course','$gradsit', '$nbpo', '$pos', '$hdate', '$nho', '$ref')";

在這里，沒有必要添加appid，因為它是自動遞增的。 還有一些缺少單引號。

解決方案4

  • 跳過在insert語句中發送NULL值
  • 在哪里檢查$ _POST是否為空，如果為空，則設置為$ error_flag = 1
  • 在if (isset($_POST['submit'])) { print $ _POST

希望這有助於調試。 如果仍然有問題，請檢查您的error_log
