我正在處理一個項目,我想用$_GET
方法更新另一個用戶的詳細信息。我的問題是,當用戶點擊ID,它確實去編輯頁面,但是當我改變某些東西並按下更新按鈕時,它不會更新。我不知道我在這裏做錯了什麼。如果有人能幫助我,我會非常感激。更新查詢不起作用php
//編輯
我的代碼工作,現在,大家好,我只是改變了$ _ POST到$ _REQUEST現在我的狀態更新。謝謝所有幫助我..謝謝你..這是我的編輯的代碼..我已經取出了密碼字段,但我有一個疑問..使用請求安全嗎?
<?php
include '../../connection.php';
$sid = $_REQUEST['sid'];
$query = "SELECT * FROM STUDENT WHERE STU_ID='$sid'";
$result = mysqli_query($connection, $query);
if(mysqli_num_rows($result)>0){
while($row = mysqli_fetch_assoc($result)){
$unm = $row["STU_UNAME"];
$fnm = $row["STU_FNAME"];
$lnm = $row["STU_LNAME"];
$dob = $row["STU_DOB"];
$add = $row["STU_ADD"];
$tlp = $row["STU_PHONE"];
$sem = $row["STU_SEM"];
$img = $row["STU_IMG"];
$sts = $row["STU_STATUS"];
$cid = $row["CRS_ID"];
}
}
else{
$no = "0 result!";
}
if($_SERVER["REQUEST_METHOD"] == "POST"){
//insert details in data
$sid = $_POST["sid"]; $snm = $_POST["snm"]; $fst = $_POST["fnm"]; $lst = $_POST["lnm"]; $sdb = $_POST["dob"];
$sad = $_POST["add"]; $shp = $_POST["tlp"]; $stt = $_POST["sts"]; $sem = $_POST["sem"]; $cid = $_POST["cid"];
$sql = "UPDATE STUDENT SET
STU_ID='$sid', STU_UNAME='$snm', STU_FNAME= '$fst', STU_LNAME='$lst', STU_DOB='$sdb', STU_ADD='$sad', STU_PHONE='$shp',
STU_STATUS='$stt', STU_SEM='$sem', CRS_ID = '$cid' WHERE STU_ID='$sid'";
//check if data is updated
if (mysqli_query($connection, $sql)) {
header("Location: searchStudent.php");
}
else {
echo "Error: " . $sql . "<br>" . mysqli_error($connection);
}
}
?>
