我有一個表格，如果有數據庫記錄，我使用php進行檢查。 如果數據庫中存在記錄，則輸入框將自動填充。 我已經這樣做了，不用擔心。 問題是如果我想修改輸入框中的文本，那麼我不能得到輸入框的新值。我怎樣才能做到這一點？從回聲輸入字段獲取值
<?php
$title="Welcome";
require("connect.php");
session_start();
if(isset($_SESSION['CurrentUser'])) {
$AppID=$_SESSION['CurrentUser'];
}
else{
header("Location: ApplicantLogin.php");
}
$Flag = mysql_query("SELECT EXISTS(SELECT 1 FROM Submission WHERE AppID='$AppID') AS FLAG");
$SubmissionDetailSQL=mysql_query("SELECT * FROM Submission WHERE AppID = '$AppID'");
function saveData() {
if (isset($_POST['QualificationPlace']) && isset($_POST['QualificationType']) && isset($_POST['QualificationInstitution']) && isset($_POST['QualificationMonth'])
&& isset($_POST['QualificationYear']) && isset($_POST['QualificationSubject']) && isset($_POST['QualificationGrade'])){
$QualificationPlace = $_POST['QualificationPlace'];
$QualificationType = $_POST['QualificationType'];
$QualificationInstitution = $_POST['QualificationInstitution'];
$QualificationMonth = $_POST['QualificationMonth'];
$QualificationYear = $_POST['QualificationYear'];
$QualificationSubject = $_POST['QualificationSubject'];
$QualificationGrade = $_POST['QualificationGrade'];
mysql_query("UPDATE Submission SET QualificationPlace='$QualificationPlace', QualificationType='$QualificationType',
QualificationInstitution='$QualificationInstitution', QualificationMonth='$QualificationMonth', QualificationYear='$QualificationYear',
QualificationSubject='$QualificationSubject', QualificationGrade='$QualificationGrade' WHERE AppID=$AppID");
}
}
if (isset($_POST['savebtn'])) {
saveData();
header("Location: applicantCase.php");
}
if (isset($_POST['nextbtn'])) {
saveData();
header("Location: ApplicantApplyEmployment.php");
}
if (mysql_fetch_array($Flag) == True) {
while ($SubmissionDetails=mysql_fetch_array($SubmissionDetailSQL)){
$_SESSION['QualificationPlace']=$SubmissionDetails['QualificationPlace'];
$_SESSION['QualificationType']=$SubmissionDetails['QualificationType'];
$_SESSION['QualificationInstitution']=$SubmissionDetails['QualificationInstitution'];
$_SESSION['QualificationMonth']=$SubmissionDetails['QualificationMonth'];
$_SESSION['QualificationYear']=$SubmissionDetails['QualificationYear'];
$_SESSION['QualificationSubject']=$SubmissionDetails['QualificationSubject'];
$_SESSION['QualificationGrade']=$SubmissionDetails['QualificationGrade'];
}
}
include("html/applicantsheader.html");
include("html/ApplicantApplyQualifications.html");
include("html/footer.html");
?>
的HTML代碼： 「$ _ SESSION [ 'QualificationPlace'。」

問題一定值=。但我怎樣才能做到這一點？
您是否在問如何獲得現場價值 - 就像使用Ajax一樣？我有點不清楚。您想如何以及何時修改該值？ – user1167442
這個概念是創建一個將分成幾部分的表單。每個部分在最後都會有一個保存按鈕，用戶可以存儲他迄今爲止輸入的表單詳細信息，稍後可以填寫其餘部分。當用戶返回到表單時，我想從數據庫中取回這些輸入。我能夠取他們。但如果我想修改html代碼中的回顯行，請不要讓我。就像我不能修改它的一個常數值。 – Bobys
你的代碼對sql注入是開放的。 [你應該逃避你的輸入]（http://stackoverflow.com/questions/60174/how-can-i-prevent-sql-injection-in-php）。 – CUGreen
